It is a functional postulate with no established physical referent: no enzyme, hormone, transit-time measure, microbiome signature, resting metabolic rate or imaging finding has been shown to correspond to it. No study located here tests an agni instrument against a pre-specified, independently established physiological criterion. The closest thing to such an attempt is the serum-lipid comparison in the 2017 agnibala instrument paper (PMID 27381899), and its own abstract frames the lipids not as a validating criterion but as an after-the-fact check, run once \"the statistical validity and reliability\" had already been confirmed, on \"the practical utility of the newly developed tool\"; the result, that \"the lipid parameters vary significantly according to the status of Agni\" in 300 volunteers aged 18-40, is a cross-sectional association with no reported adjustment for diet or BMI. An earlier version of this section said both that no study even attempts a biological criterion and that the lipid result was the strongest single result; those two statements cannot both stand, and the first has been narrowed to what is defensible. What modern literature exists is dominated by two genres. The first is narrative reviews that restate the thirteen-agni scheme in the vocabulary of enzymes, free radicals or mitochondria, propose a correlate as future work, and stop (PMID 22131747, PMID 22556911 are representative). The second is questionnaire development: at least four separate self-report instruments exist (PMID 26283805, PMID 27381899, PMID 41774580, plus the JAQ used in PMID 35101333), none validated against any external criterion, most validated only by Cronbach's alpha, none reporting test-retest reliability in the papers located here, and no two agreeing on item content. That the field is now commissioning a COSMIN and QUADAS-2 systematic review of these instruments (PMID 42314162) is itself an admission that their psychometric standing is unknown. There is exactly one chance-corrected reliability measurement bearing on agni, and it is unfavourable: four Ayurvedic experts assessing the same 30 knee osteoarthritis patients reached kappa between 0 and 0.4 for central diagnostic aspects including prakriti and agni, despite 95 percent consensus agreement on the final diagnosis (PMID 30653338). Treatment studies for agnimandya (PMID 28827955, PMID 29491670) are small, open-label and scored on the same symptom lists used to make the diagnosis, which makes them close to circular. The honest summary is that agni is an elaborate and long-sustained classical model of digestion and tissue metabolism which is not internally consistent. Sushruta identifies agni with pitta outright while Charaka runs a three-tier jatharagni, bhutagni and dhatvagni architecture (contested #1); the number of agnis is unsettled and the familiar thirteen has no scriptural locus (contested #2); the four states are presented by Charaka's Vimana 6 as four kinds of person and by Sushruta's Sutrasthana 35, and by Charaka's own Chikitsasthana 15/70, as three derangements plus one normal state (contested #5); and samagni is defined behaviourally by Charaka and by output by Sushruta, criteria that select different people (contested #6). The earlier description of the model as \"coherent and internally consistent\" was a concessive this record's own contested section refutes, and it has been withdrawn rather than the contested material trimmed to fit it. Clinical use rests on symptom-pattern recognition; trained experts do not reliably agree on it; and it has not been operationalized in a way that would let an outside observer confirm or refute it.","summary":"Agni is the Ayurvedic name for the transformative capacity held to be responsible for digestion and for tissue-level metabolism. The classical claim is that food does not nourish the body directly: it must first be \"cooked\" by agni into rasa (a nutrient essence) and kitta (waste), and that the period of life, complexion, strength, ojas and the life-breaths all depend causally on this capacity (Charaka Chikitsasthana 15, Kaviratna's Lesson XV verses 2-3, quoted below). Charaka's Chikitsasthana 15 treats agni as the root of health, disease and death, and the tradition distributes it across a central digestive fire in the gut (jatharagni), five elemental fires (bhutagni) and seven tissue-level fires (dhatvagni). The total of thirteen is a textbook figure and not a scriptural one: Charaka enumerates the five and the seven separately and nowhere states a total, so the summary carries the hedge rather than leaving it to the contested block (see contested #2 and the Ci.15 verses 12-14 entry). A parallel classification describes four functional states of the digestive fire: balanced (sama), irregular (vishama), intense (tikshna) and weak (manda), the last being agnimandya. Whether those four are four kinds of person or three derangements of one person's fire plus one normal state is disputed inside the classical corpus itself, and so is the definition of the balanced state (contested #5, #6). The familiar maxim that weak agni is the etiological starting point of most disease is a teaching commonplace whose usual locus, Ashtanga Hridaya Nidana 12, has not been verified against a primary text in this project; it is therefore not asserted here, and the narrower claim the quoted text does support is that jatharagni is the root of the other fires and that they rise and fall with it (Ci.15, Kaviratna's verse 38). Agni is a functional postulate, not an organ or a substance: Sushruta's own metrical text calls it \"invisible owing to its extremely subtle essence\", and the classical texts do not locate it in anything measurable beyond its effects on appetite, digestion, stool and bodily strength. The word \"absorption\", which an earlier version of this summary used, has been removed: it appears in no quoted verse and is a modern physiological term that does not belong in a statement of the classical claim.","contested":[{"question":"Is agni identical with pitta, or distinct from it?","positions":["Sushruta states the identity flatly: pitta is the same as fire, there is no other fire in the organism than pitta, and pitta in its digestive seat is therefore called pachakagni (Su.Su.21).","Charaka's usage keeps agni as a functional agent distinct from pitta as a dosha, and treats agni disorder and pitta disorder as separately manageable; commentators harmonize the two by making agni the functional aspect of pachaka pitta.","Modern Ayurvedic physiology literature acknowledges the tension openly: PMID 22131747 states that although the classics give examples equating them, 'some doubt arises behind this concept, that Pitta is Agni'. No resolution is offered."]},{"question":"How many agnis are there?","positions":["The standard textbook figure is thirteen: one jatharagni, five bhutagni, seven dhatvagni.","Charaka Ci.15 as translated by Kaviratna enumerates the five and the seven separately and never states a total, so thirteen is a later systematization rather than a scriptural number.","PMID 22131747 records a third position from within the tradition: agni is in principle innumerable, present in every paramanu of the body, and the enumeration varies across classical texts."]},{"question":"Do the four agni states map onto the doshas in the conventional way?","positions":["Classical doctrine and most teaching material assign vishamagni to vata, tikshnagni to pitta and mandagni to kapha.","The one empirical study that tested this (PMID 35101333) found instead that vata-pitta individuals had tikshnagni, vata-kapha had mandagni and kapha-pitta had vishamagni, and reported this as a positive finding without addressing the mismatch with the dvandvaja-to-single-dosha translation it implies."]},{"question":"Are the four agni states discrete types or points on a continuum?","positions":["Charaka Ci.15/70 treats them categorically: three of the four are by definition grahani-faults, i.e. disease states.","The instrument literature treats them as four scored subscales that a single person can load on simultaneously (PMID 41774580 reports four correlated subscales, with the samagni subscale the least internally consistent), which is closer to a dimensional than a categorical model. Neither literature addresses the conflict."]},{"question":"Are the four agni states four kinds of person, or three derangements of one person's fire plus one normal state?","positions":["Four kinds of person. Charaka Vimanasthana 6 closes its list of the four with Kaviratna's aphorism 14: \"These are the four different kinds of fire of four different kinds of persons.\" The same aphorism describes the keen fire in purely positive terms, as the one \"which can bear all kinds of dietary riotousness\", with no suggestion that it is a disorder.","Three derangements plus one normal state. Sushruta Sutrasthana 35: \"One of these kinds is due to it not being in any way affected by the deranged humours of the body, while the other three are respectively ascribed to the fact of their becoming so deranged.\" Sushruta also prescribes treatment for the keen fire once it becomes atyagni, which Charaka's Vimana 6 description does not contemplate.","Charaka takes Sushruta's side against his own Vimana 6 wording. Chikitsasthana 15, Kaviratna's verse 70, quoted in the classical block: \"Excepting that fire which is called 'Sama,' the three others, (viz., 'Vishama,' 'Tikshna,' and 'Manda'), are, the Rishis say, called 'Grahani-faults.'\" So the disagreement is not only between the two texts but inside Charaka, and this record previously quoted only this side of it.","The modern instrument literature presupposes the derangement reading without arguing for it, by scoring all four as subscales of a single person (PMID 41774580). None of the secondary sources located here states that the dispute exists."]},{"question":"How is samagni, the balanced state, actually defined?","positions":["Behaviourally, by response to dietary provocation. Charaka Vimanasthana 6, Kaviratna's aphorism 14: \"That fire is said to be even which becomes vitiated by dietary riotousness, but which exists without being deranged when no dietary riotousness is indulged in.\" On this criterion samagni is a fire that does misbehave, when provoked.","By output, by complete and timely digestion. Sushruta Sutrasthana 35: \"The digestive heat, which fully digests the ingested food at the proper time without the least irregularity, thus reflecting the continuance of the bodily humours in their normal state, is called Samagni.\" On this criterion samagni is a fire that does not misbehave.","The two criteria select different people and nothing located here reconciles them. Charaka Vimana 6 adds a third handle in the next aphorism, aphorism 15, which is constitutional rather than either behavioural or output-based: \"of those persons that are of equable wind, bile, and phlegm, and that are in their normal state, the (digestive) fires are even.\"","The ambiguity shows up in the measurements. The one instrument that scores samagni as its own subscale found it the least internally consistent of the four, with subscale alphas between 0.57 and 0.83 and, in the authors' words, \"all subscales except Samagni meeting conventional reliability thresholds\" (PMID 41774580)."]},{"question":"Is an agni state a stable trait of the person, or a condition that comes and goes?","positions":["Trait. Charaka Vimanasthana 6, Kaviratna's aphorisms 14 and 15, speaks of \"four different kinds of fire of four different kinds of persons\" and ties the even fire to persons \"of equable wind, bile, and phlegm, and that are in their normal state\". A kind of person is not a passing condition.","State. The same author's grahani chapter makes the fire's condition a consequence of recent conduct. Charaka Chikitsasthana 15, Kaviratna's verses 41-43, quoted in the classical block: \"From abstention from all food, from eating food that is indigestible, from eating to excess ... from suppression of the urgings (of nature), the (digestive) fire is vitiated.\" Every item on that list is something the person did.","The modern literature does not settle it and at present cannot: no test-retest reliability has been published for any agni instrument in the papers located here, so there is no measurement of how much one person's score moves over time. One cross-sectional survey reports that 61.7 percent of rotating-shift workers had a change in agni status, shifting toward vishamagni on night shifts (PMID 42519781), but both the change and its cause are self-reported."]}],"notKnown":["Whether agni has any physical correlate at all. Gastric acid output, pancreatic and brush-border enzyme activity, gastric emptying and orocaecal transit time, bile flow, resting metabolic rate, mitochondrial function and gut microbial composition have all been proposed in review articles as candidates. For the microbiome candidate the negative is now a searched one rather than an asserted one: PubMed queries run on 2026-10-06, \"prakriti AND microbiome\" (9 records), \"jatharagni AND microbiome\" (0 records) and \"ayurveda AND (agni OR jatharagni) AND (gut microbiota OR microbiome)\", returned constitution-stratified microbiome work (PMID 29487572, PMID 34148877, PMID 32718805, PMID 31719221, PMID 37655174) in which the stratifier is prakriti and no agni assessment is taken, and no study in which an agni assessment was either the exposure or the outcome. That is a bounded search of one database under those terms on that date, and it cannot support a claim that no such study exists. The other candidate correlates have had no equivalent search documented here, so for those the gap is simply unexamined.","Whether the four states are stable traits, states that fluctuate day to day, or artefacts of the questionnaire. No test-retest reliability has been published for any agni instrument.","Whether two trained examiners assessing the same patient would assign the same agni state, and under what conditions. One chance-corrected measurement exists and is unfavourable: in 30 knee osteoarthritis patients assessed in sequence by 4 Ayurvedic experts, kappa for central diagnostic aspects including agni fell between 0 and 0.4 while raw consensus agreement on the final diagnosis was 95 percent (PMID 30653338). What is not known is whether agreement is any better in other conditions, at other centres, with other raters, or when a structured instrument is used instead of clinical judgement, since that study rated expert assessment and not any published agni questionnaire. The claim this record previously carried in this slot, that no interrater reliability figure exists for agni, was false, contradicted eleven other records in this project, and has been withdrawn.","Whether agni assessment adds anything predictive beyond a general gastrointestinal symptom score. No study has compared an agni instrument against, for example, a validated dyspepsia or GIQLI score to test discriminant validity.","Whether the dhatvagni and bhutagni tiers correspond to anything at all. All instrument work measures jatharagni only; the seven tissue fires and five elemental fires have never been operationalized.","Whether agni state at baseline predicts any clinical outcome prospectively. Every study located is cross-sectional or a short uncontrolled intervention.","How the three-phase avasthapaka model (sweet, sour, pungent phases generating kapha, pitta and vata in turn) relates to measured gastric and intestinal pH and secretion profiles. The correspondence is asserted in reviews and has not been measured.","Whether the therapeutic categories built on the concept, deepana (kindling) and pachana (digesting), act through any agni-specific mechanism or simply through known prokinetic, carminative and bitter-stimulant pharmacology of the herbs involved.","Whether the fourfold scheme is pan-classical. The critic finding asserted that Sharngadhara Samhita Purva Khanda 7.26 omits sama and adds bhasmaka. That could not be verified. No public-domain English Sharngadhara translation was located, and searching secondary sources on 2026-10-06 returned the standard four states, sama, vishama, tikshna and manda, attributed to Sharngadhara, rather than the substitution the finding describes. The claim is therefore recorded as unchecked, Sharngadhara is cited nowhere in this record, and the question of which classical and post-classical texts carry which enumeration of the states remains open.","Where Vagbhata states the four agni states. An earlier pass on this cluster cited Ashtanga Hridaya Sutrasthana 1/8 for them; this pass cites nothing for them. Su.1 and Su.13 are not the same passage, no public-domain English translation of Ashtanga Hridaya exists, and the conflict was not resolvable against a quotable text here. The record therefore makes no claim about where Vagbhata states the four states, and the Ashtanga Hridaya entry below is cited only for the ama and weak-agni account at Su.13, where it is recorded as located and not quoted.","The locus of the maxim that weak agni is the starting point of most disease. It is usually attributed to Ashtanga Hridaya Nidana 12. It was recorded as unverifiable against a primary text in the previous pass and was not verified in this one, and no public-domain English Ashtanga Hridaya translation exists to quote from. The maxim has accordingly been removed from the summary, and it must not be cited as a locus until checked against a primary text.","How agni maps onto standardized terminology, and whether the four states map onto anything codeable. The comparator material exists in this project's agni term record: WHO International Standard Terminologies on Ayurveda (2022) renders agni at ITA-2.6.1 as \"Digestive, metabolic factors\", deliberately avoiding \"fire\", and treats kayagni as a separate headword at ITA-2.6.2, while NAMASTE / National AYUSH Morbidity Codes carry no standalone code for agni and admit it only as the disorder heading \"derangement of digestive power\" (agnivaishamyam). What is not known is whether any of sama, vishama, tikshna or manda maps onto a NAMASTE or ICD-11 TM2 category, and that comparator work was flagged in the previous pass as something to gather before drafting and has still not been done. The WHO ISTA licence, CC BY-NC-SA 3.0 IGO, also remains unsettled for publication.","What the post-classical nibandha layer says about agnimandya. This record covers Charaka and Sushruta only. Madhava Nidana chapter 6 (Grahani Nidana), Bhavaprakasha Purva Khanda on agnimandya, and Yogaratnakara's amavata nidana were all named as gaps and are cited nowhere here, because no public-domain English translation of any of the three was located and this project's rule is no quote, no citation.

No study retrieved for this record tested ahara vidhi vidhana, the twelve rules, as a protocol; none tested the eight determinants; and none tested any classical viruddha pair. What the mainstream nutrition literature contains is evidence about separable modern constructs that the classical rules also happen to recommend: eating rate, mindful eating, portion size, and the length of the eating window. A trial of one of those is not a test of the classical doctrine, any more than a trial of handwashing is a test of shaucha. The supporting citations in this record are therefore citations about component behaviours, and the concept drift between them and the doctrine is stated here rather than left for a reader to notice.\n\nTaking the components one at a time. Eating rate: the association with adverse metabolic outcomes replicates across two independent meta-analyses, Ohkuma 2015 (23 studies, pooled OR 2.15 for obesity) and Yuan 2021 (29 studies, 465,155 subjects, OR 1.54 for metabolic syndrome), but the pooled designs are overwhelmingly cross-sectional with self-reported eating speed and the reviews establish association only. Mindful eating: Warren 2017 reviews 68 publications and concludes that compelling evidence for weight management is lacking, with clearer effects confined to binge and emotion-driven eating. Eating window: Sun 2023, the nearest modern analogue to 'eat only after the previous meal is digested', finds no significant benefit beyond the calorie restriction it produces, and is clock-keyed where the classical rule is symptom-keyed. So the honest statement about the procedural layer is that several of its components are separately plausible on independent grounds, and that the rule set as a set, in the form Charaka gives and for the reasons he gives, is untested. It should not be presented as the layer that has standing.\n\nThe eight-determinant framework has no empirical evaluation located here at all. It is a conceptual checklist, and no retrieved study tested whether it adds predictive value over ordinary dietary assessment.\n\nThe doctrine of viruddha ahara, the distinctive and most heavily promoted part, has essentially no empirical support in the literature retrieved here. The only randomised evidence located that bears on the general food-combining claim, Golay 2000, is null: 54 obese inpatients, energy matched at 1100 kcal per day, no significant difference in weight loss between a dissociated and a balanced diet. No classical viruddha pair, the milk-and-fish prohibition included, was found to have been tested in humans by the searches recorded in this record or by the named multi-database search reported in the 2024 JDRAS review, which searched PubMed, Web of Science, Scopus, MEDLINE and the AYUSH and NAMASTE portals from 2000 to 2024 and concluded that the mechanisms remain unexplored. The indexed Ayurvedic literature on the topic consists of narrative reviews that restate the classical lists and propose future biomarker work. Two peripheral empirical threads exist, HMF formation in heated honey and the eating-rate association, and both are partial parallels at best.\n\nMeanwhile the classical texts hedge the doctrine themselves, and the passages added hedge it further. Sushruta Sutrasthana 20 says habituation and small quantity neutralise the harm; Charaka says prior neutralising articles prevent the diseases; and Charaka Sutrasthana 27 says outright that for people of strong digestive fire who are habituated to heavy food and devoted to active work the question of heaviness need not be looked into at all. Sushruta Sutrasthana 46 then exempts the evening meal from his own adhyashana rule. The category as stated cannot be tested without first specifying dose, habituation status, activity level, time of day and prior treatment. A reference work should state that viruddha ahara is at present a traditional prohibition list with no validated operational definition and no outcome data located here.","summary":"Ahara vidhi is the classical Ayurvedic doctrine of how to eat, as distinct from what nutrients to obtain. It has three layers. First, quantity (matra) is governed jointly by the article eaten and by the eater's digestive capacity (agni): Charaka's Sutrasthana 5 makes the measure depend on the power of the digestive fire, and in the same chapter denies that it is independent of the article, prescribing half or three quarters of satiety for heavy articles and short of full satiety even for light ones. Second, Charaka's Vimanasthana 1 gives eight determinants that must be jointly considered for any food (its nature, processing, combination, quantity, place of origin, time, the rules of its consumption, and the eater), followed by twelve procedural rules for the act of eating, of which three are conditions on the food itself rather than on the eater's conduct. Sushruta's Sutrasthana 46 adds a parallel account of three faulty modes of eating: samashana (wholesome and unwholesome eaten together), vishamashana (eating too much or too little, at irregular intervals or at improper seasons) and adhyashana (eating before the previous meal is digested). Third, the doctrine of viruddha ahara holds that certain foods, or foods in certain combinations, processings, quantities, places, times or bodily states, become hostile to the body's constituents and produce a long list of diseases up to and including death. The classical texts themselves qualify the doctrine: habituation, small quantity, strong digestion, physical exercise and prior neutralising treatment are all said to blunt the harm, which makes viruddha a conditional rather than an absolute category.","contested":[{"question":"How many kinds of viruddha are there?","positions":["Standard modern Ayurvedic teaching gives eighteen (desha, kala, agni, matra, satmya, dosha, samskara, virya, koshtha, avastha, krama, parihara, upachara, paka, samyoga, hridaya, sampad, vidhi), cited to Charaka Sutrasthana 26.","The Kaviratna translation retrieved here gives a much shorter grouping at the corresponding place (hostile by nature, by admixture, by dressing or relish-admixtures, by place/time/measure), and uses a different verse numbering.

Charaka adds that prior neutralising articles prevent the diseases. On the texts' own terms the category is conditional.","Charaka himself scopes the rules to a population: at Sutrasthana 27, printed markers 345 to 346, he says that heaviness and lightness need to be ascertained for the weak, the inactive, the unwell and the delicate, and that for those of blazing digestive fire who are habituated to heavy food and devoted to active work it is not at all necessary to look into the question. That is a second text, and the same move Sushruta makes, which makes the conditional reading the better supported of the two on the texts' own words."]},{"question":"Does 'eat after the previous meal is digested' mean a fixed interval or a symptom-based judgement?","positions":["Charaka Vimana 1 explicitly ties it to 'the indications of digestion' (appetite returning, the ducts unobstructed, the fire kindled), which is a symptom-based rule with no clock in it.","Modern Ayurvedic and popular presentations frequently convert it to a fixed three-to-six-hour gap, and it is often equated with time-restricted eating. That conversion is not in the source and changes what is being claimed."]},{"question":"Is 'eat warm, unctuous food' a digestibility rule or a doshic rule?","positions":["Charaka's own stated reasons are physiological in idiom: warm food causes perspiration, kindles the digestive fire, is soon digested, moves vata in its natural direction and dries kapha.","Those reasons are internal to the doshic system and are not independent observations; no source retrieved offers an argument for warm food that does not presuppose the system."]},{"question":"Do the texts agree that eating before the previous meal is digested is always a fault?","positions":["Charaka Vimanasthana 1 makes 'only after the previous meal is digested' one of the twelve rules without stated exception, and Sushruta Sutrasthana 46 names the violation adhyashana and says it is injurious and may end fatally.","Sushruta Sutrasthana 46 then exempts the evening meal in its closing passage: a man may take a meal at night even if the daytime food is still undigested without committing adhyashana, because the heart is unfolded during waking, while the same conduct overnight does count as a fault and is answered by fasting the next day. So the rule is not uniform even within Sushruta, and the exception rests on a diurnal claim about the heart that is internal to the system and was not independently sourced here."]}],"notKnown":["There is no validated marker or instrument for jirna (completed digestion), which is the trigger condition for the central timing rule.","No classical viruddha combination was found to have been tested in humans.

The modern literature carried in this record tests separable constructs (eating rate, mindful eating, eating window, portion size) that overlap the rules in behaviour and not in object, and that gap is not closed by any source here.","Whether the eight determinants and the twelve rules were ever intended as separable claims at all, or only as parts of a single doshic account. Three of the twelve rules (ushna, snigdha, viryaviruddha) are conditions on the food, so the behavioural reading of the set is an imposition on it, and nothing retrieved here licenses testing the rules one at a time as independent interventions.","The dvadasha ashana pravichara, the twelvefold enumeration of modes of taking food, is referred to in modern Ayurvedic teaching and is NOT covered by this record. It was searched for and not located: a search for 'twelve' across the whole retrieved Kaviratna Charaka returns no enumeration of modes of eating (the twelve it does enumerate at Sutrasthana 27 are the twelve food groups, dvadasha varga, which is a different list), and the GRETIL Sanskrit Charaka file retrieved here covers only Sutrasthana 1, 12, 26, 27, 28 and parts of the later sthanas, with no occurrence of ashanapravichara.

Every ama measurement located in the peer-reviewed literature is a symptom checklist assembled from the same classical verses that define the concept, which makes validation circular: the instrument agrees with the doctrine because it was built from it. Three studies located here attempt to break that circle, and none succeeded cleanly. The Ama Assessment Instrument correlated with ESR at r=0.287 at baseline, falling to 0.160 by the third follow-up, and with DAS-28 at r=0.231 at baseline (PMID 36822147), weak enough that the authors reframed the weakness as evidence of independence, and a later group abandoned those comparators entirely (PMID 42497784). The stronger correlation with CDAI (r=0.645) in that later study is the best result located but comes from 38 RA patients and against a composite that is itself largely subjective, so it may reflect general illness severity; that same group's proposal to merge the Ama-score and CDAI into one composite is difficult to reconcile with the score measuring something CDAI does not, which is the gatherer's reading of the proposal and not a position either author states. The only attempt located at an observer-independent measure, tongue-coating photography scored by five clinicians, failed its pre-specified analysis outright (PMID 42142499) and survives only through post-hoc regional subgroups. A fourth study is sometimes read as relevant and is not an attempt on the circularity: the untargeted metabolomics of RA patients on Ayurvedic treatment (PMID 38972279) neither defines nor scores ama, so it cannot test an ama measure. It is recorded above because it is the one open-ended biochemical method located in this area, and it produced no ama-specific signature. The mechanistic correlates named in Ayurvedic writing are not addressable from that writing alone. Free radicals were proposed in 1999 (PMID 22556911) with no data. Gut dysbiosis is proposed in narrative review (PMID 33281390), which argues from the classical diet rules for amavata to published effects of individual foods without measuring ama or microbiota in anyone. Endotoxin and intestinal permeability are invoked by analogy to a primary literature that the Ayurvedic sources do not cite and that does not mention ama: the metabolic-endotoxemia work, which is a mouse study (PMID 17456850), and the zonulin barrier-function review (PMID 21248165). Those two are recorded above so that the analogy is at least checkable. No study located in the searches recorded under gatheringNotes measures endotoxin, permeability, dysbiosis or an oxidative marker against any ama assessment, and the searches that were run are named there so the limits of that statement are visible. The concept also carries an unresolved internal problem that the modern literature located here does not engage: Charaka's ama, as rendered by his public-domain translator, is largely literal undigested food and undigested rasa in the gut, whereas the systemic circulating toxin of modern Ayurvedic writing owes more to Vagbhata and to twentieth-century reinterpretation. A second problem, whether ama names anything beyond the consequences of weak agni, is recorded under notKnown rather than asserted here, because no source located poses it. What this record supports is narrow. Ama is the traditional name for a symptom cluster of heaviness, lassitude, anorexia, coated tongue and impaired digestion; that cluster can be scored by a single examiner using a checklist derived from the classical signs; whether two examiners scoring the same patient would agree is not known, which is notKnown item 4; and nothing located here establishes ama as a distinct substance or process rather than a name for the cluster. The record makes no claim that the concept is clinically usable or that the cluster tracks any distinct underlying process, because it holds no evidence that would support either.","summary":"Ama is the Ayurvedic name for the product of failed digestion: material that has been taken in but not properly transformed, and which is held to become a cause of disease rather than a source of nourishment. The classical mechanism is straightforward in outline. When agni is weakened by fasting, overeating, incompatible or heavy food, mistimed therapy, illness, seasonal mismatch or suppression of natural urges, food is not digested, and the undigested residue is said to turn sour and to act like a poison. Charaka describes this material combining with each of the doshas to produce their characteristic diseases, entering urine, stool and the tissues, and in acute form producing the conditions visuchika and alasaka, which he says physicians call ama-visha, the poison of undigested food, because the symptoms resemble poisoning. Later texts, principally Vagbhata, reify ama into a general morbid substance that blocks the channels and adheres to doshas to make them sama, with a standard ten-sign checklist (heaviness, lassitude, loss of appetite, coated tongue, malaise and so on) distinguishing sama from nirama states. Ama has no stated composition, location outside the gut in the earliest sources, or means of detection other than that symptom list.","contested":[{"question":"What is ama? A product of failed digestion, or the doshas themselves?","positions":["Undigested or improperly formed rasa retained in the amashaya because agni is weak. This is Ashtanga Hridaya Su.13/25 and the standard modern teaching.","Greatly increased doshas that mix with one another and thereby become toxic, on the analogy of poison arising in stored kodrava grain. Vagbhata gives this at Su.13/26 as an alternative immediately after the first definition, so the tradition records the disagreement without resolving it.","In Charaka the term is used more loosely still, for literally undigested food passed by a vitiated grahani (Ci.15/55-56) and for ama-rasa spreading through the body (Ci.15/74). No single referent is fixed."]},{"question":"Is ama a localized gut phenomenon or a systemic circulating entity?","positions":["Charaka's clearest statements are gut-localized: food not digested in the stomach, food adhering to the pakvashaya, undigested matter discharged in stool.","Charaka also states that the poison enters urine, stool and the dhatus, and that ama-rasa may spread over the whole body requiring fasting and pachana, which supports a systemic reading.","Modern Ayurvedic writing treats ama as unambiguously systemic, blocking srotas anywhere in the body. This is the reading that underwrites all the ama-in-rheumatoid-arthritis research, and it is a stronger claim than the earliest source clearly supports."]},{"question":"Does the Ama score measure ama, or does it measure disease activity?","positions":["Pandey and colleagues (PMID 36822147) argue the instrument is an independent disease-status marker precisely because it correlates only weakly with ESR and DAS-28.","Wagh and colleagues (PMID 42497784) found it correlates strongly with CDAI (r=0.645) and propose merging the Ama-score and CDAI into a single composite measure.","Wagh and Raut (PMID 38056374) note it has never been tested in any non-rheumatic ama-dominant disease, so its specificity to ama rather than to inflammatory illness is unknown."]},{"question":"Is coated tongue a valid sign of ama?","positions":["It is the sign most relied on in clinical practice and is treated as the canonical external marker of ama.","The only quantitative test of this located here (PMID 42142499) found no significant correlation between whole-tongue coating index and Ama score in its pre-specified analysis; only a posterior-middle sextant subgroup correlated.","Tongue coating is independently determined by oral microbial biofilm, hygiene, smoking, hyposalivation and medication, none of which was controlled in that study, so even the positive subgroup finding has an obvious alternative explanation."]},{"question":"Is ama-visha a distinct toxic entity or a descriptive label?","positions":["Charaka Vi.2 states plainly that physicians call it the poison of undigested food because its symptoms resemble poisoning, which is an explicitly analogical naming.","Much modern writing treats ama-visha as a claim about actual toxicity, and builds endotoxin and free-radical analogies on it. The classical text does not make that claim."]}],"notKnown":["What ama is, in any material sense. No composition, no chemical class, no proposed molecule has been isolated or measured. Candidates named in reviews (free radicals, endotoxin/LPS, advanced glycation end products, undigested macromolecules, dysbiotic metabolites) have not been tested against any ama assessment in the literature located here.","Whether anything measurable actually accumulates in a person judged sama and clears in one judged nirama. No before/after biochemical study of ama-pachana treatment has been located.","What srotorodha, channel obstruction, corresponds to. This is the load-bearing step converting a digestive failure into systemic disease, and nothing located specifies it. That absence is now a searched one rather than an assumed one, which is what the revision was asked to establish: a PubMed search on 2026-10-06 for 'srotorodha' returned no records at all, and a search for 'srotas' returned 21, whose titles are conceptual appraisals of particular srotas (for example PMID 23723638, a critical appraisal of doshavaha srotas, and PMID 22131705 on herbs acting on mutravaha srotas) and disease-specific case reports; none reports a measurement of channel obstruction. The search did not cover transliteration variants, Sanskrit-language sources, the AYUSH Research Portal or DHARA, or the many Ayurvedic journals that PubMed does not index, so this remains the result of a bounded search and not an established absence. No one has been identified as having attempted to specify the step.","Whether ama assessment is reproducible between examiners. No interrater reliability figure for an ama score was located in the PubMed searches recorded under gatheringNotes; the only agreement statistic found (0.73-0.76) was for tongue-photograph coating scores, not for ama itself. This gap is load-bearing: the record's description of ama as a scorable symptom cluster assumes only that one examiner can apply the checklist, and says nothing about two.","The prevalence and distribution of ama scores in healthy populations. One study included 20 healthy volunteers (PMID 42497784) and found their scores indistinguishable from treated RA patients in remission, which is a single small data point and the only normative information located.","Whether ama scores respond to non-Ayurvedic treatment. If a DMARD-induced remission lowers the ama score as much as ama-directed therapy does, the score is tracking inflammation rather than ama; the remission group in PMID 42497784 was on treatment but the question was not framed or tested. The one blinded trial located in the paradigm ama disease, individualized classical Ayurveda against methotrexate and their combination (PMID 21617554), found no statistically significant difference between arms on DAS28-CRP and ACR response, but it recorded no ama score at all, so it does not answer this question either. It does show that the trial design the question needs is achievable.","Whether the sama/nirama sequencing rule, that ama must be digested before nourishing or oleating therapy, actually improves outcomes. This is one of the most consequential practical rules in Ayurveda and no comparative trial of the sequencing itself has been located.","Whether the classical acute ama disorders map onto anything modern. The two public-domain translators are the source of the modern equations, and they do not agree. Kaviratna's Charaka renders Visuchika as cholera and Alasaka as Tympanites in his running text (Lesson XIX, printed p. 217) and repeats both in his own footnotes at Vimanasthana 2 (printed p. 466, each marked '- T.'). Bhishagratna's Sushruta also renders Visuchika as 'cholera' (Sutrasthana XXI, 'Sthana-Samshrayam', printed p. 207), but the occurrences of Alasaka located in his translation render it 'flatulence' (Sutrasthana XLII, printed p. 387) or leave it untranslated, so the alasaka-tympanitis equation should be attributed to Kaviratna alone. No examination of either equation was located in the searches recorded here, and both are probably artefacts of early-twentieth-century translation practice.","Whether ama is one thing. The concept is applied to acute food poisoning, chronic dyspepsia, coated tongue, rheumatoid inflammation and general malaise; nothing establishes that these share a mechanism rather than a vocabulary.","Whether ama is a category distinct from agnimandya at all, that is, whether the concept does any work beyond naming the consequences of weak agni. The question can be put from the record's own quoted material: Charaka's list of the signs of indigestion at Ci.15/44-45 already contains 'disgust for food' and 'lassitude of the limbs', which are aruchi and alasya among the ten sama-dosha signs by which ama is identified at Ashtanga Hridaya Su.13/23-24, and a third of those ten, apakti, is impaired digestion itself, so a checklist built from those signs cannot separate ama from weak agni. No source located in this gathering, classical or modern, poses the question, so it is recorded here as unaddressed rather than as a dispute between positions. Nothing in this record answers it.","What a test of the endotoxin, intestinal-permeability or dysbiosis correlates would consist of. The primary literature these analogies borrow from (PMID 17456850, in mice; PMID 21248165, a review) does not mention ama, and the Ayurvedic writing that invokes them (for example PMID 33281390) measures neither ama nor any marker.

The classical base, stated precisely rather than by a citation count, is three loci in Charaka: the general statement at Sutra Sthana 8/10 in Kaviratna's numbering, the three-causes elaboration at Sutra Sthana 11/37 in standard numbering, and one continuous block at Sharira Sthana 1/125-136 in Kaviratna's numbering (1/118-129 standard). Twelve of the fourteen entries in the classical array resolve into those three loci, two of the twelve are Kaviratna's own translator's notes rather than text, one further entry is a bare pointer to standard-numbering locations and one is explicitly marked unsourced. The locus audit is set out in gatheringNotes. Earlier wording called this the thinnest of the four concepts in the cluster without saying thin in what, which was fair criticism. What is thin is not the Charaka attestation, which is a sustained and consecutive treatment, but two other things. Independent classical attestation outside Charaka: no public-domain translation of Ashtanga Hridaya or Ashtanga Sangraha was located, no Sushruta parallel was retrieved for this record, and nothing outside Charaka is quoted here. And the modern evidence base. The dedicated modern literature retrieved consists of narrative and conceptual reviews, mostly in non-indexed Ayurvedic journals and two in PubMed-indexed ones, which restate the Charaka verses and then assert, without measurement, that modern exposures such as headphones, screens, noise and bright light are instances of the category. Nothing retrieved here defines atiyoga, ayoga, hinayoga or mithyayoga in measurable terms for any sense; no threshold was found proposed, let alone validated; no inter-rater reliability study was located; no cohort followed under this framing was identified. There is a real and substantial modern literature on sensory exposures and health, covering noise-induced hearing loss, unsafe listening, screen time and myopia, light at night and circadian disruption, and sensory deprivation, and some of its findings are broadly congruent with the classical intuition that both excess and deprivation can harm. That congruence should be stated carefully, and the record states the caveat in the same breath as the adjacency. The mapping is this record's translation and not one the classical text makes. Those results were generated independently, with quantified exposures and comparison groups, and they neither derive from nor test the Ayurvedic scheme. The mapping is also lopsided: the retrieved epidemiology is almost entirely about excess, whereas Charaka's category covers deficient and absent and perverse contact just as much as excessive contact, so the adjacency covers at most one of the four modes and leaves ayoga, hinayoga and mithyayoga without a comparator. The one genuinely distinctive element of the classical account, mithyayoga defined by the hostile, repulsive or frightening character of the stimulus rather than by its intensity, is also the element with the least modern purchase, since it makes the harmfulness of an exposure depend on its affective meaning to a particular organism. Charaka's own translator noted in the 1890s that the scheme counts three modes after enumerating four, that the definition of asatmya is merely verbal, and that the first and third causes are scarcely exclusive of each other. No answer to those criticisms was retrieved.","summary":"Asatmyendriyartha-samyoga is the third of Charaka's three general causes of disease: pathological contact between a sense organ and its object. The scheme is formal in the sense that the same small set of failure modes is applied to each of the five senses in turn. The sense-by-sense verses enumerate four modes, excessive contact (atiyoga), absent contact (ayoga), deficient or sparing contact (hinayoga) and perverse contact (mithyayoga), where perverse means contact with objects that are hostile, repulsive, frightening or out of season. The summary verse then counts three rather than four, and this record does not resolve that discrepancy: it is recorded under contested and under notKnown rather than smoothed over by merging ayoga and hinayoga. Charaka works the modes through sense by sense: sounds too loud or too faint or terrifying, touch withheld or excessive or untimely, sights too bright or too minute or seen in darkness, tastes taken in excess or wholly abstained from or combined against habit, smells too keen or too faint or putrid. The diseases arising this way are given a name of their own, aindriyaka. The concept defines a harmful exposure as one that does not suit the particular organism, satmya being habituated suitability, which makes the judgement individual rather than absolute.","contested":[{"question":"Are there three modes of faulty contact or four?","positions":["Sharira 1.134 and the summary formulations state three.","The sense-by-sense verses enumerate four: atiyoga, ayoga, hinayoga and mithyayoga.","Kaviratna's note takes the view that hinayoga has simply been dropped from the count; other traditions merge ayoga and hinayoga into one.

On that reading the triad is one scheme applied to three domains rather than three independent causes, which makes the exclusivity question a question about the scheme and not about this category alone.

No deprivation literature for hearing, smell or taste was searched for this record, so the record carries no comparator for the ayoga and hinayoga modes at all.","Whether the category adds predictive value over quantified exposure assessment for the specific exposures where both could be applied, such as noise or screen time.","Why hinayoga is enumerated and then not counted, and whether the omission is scribal, commentarial or substantive. Kaviratna's note raises it; no commentarial resolution was located for this record.","How the individual-relative definition of asatmya is meant to be determined in a new patient before any harm has occurred.","Whether Ashtanga Hridaya and Ashtanga Sangraha in fact carry this threefold cause with the same four modes. The record previously asserted this. No edition of either text was consulted for this record and no public-domain English translation was located, so the claim is now carried in the classical array marked unsourced and the gap is stated here instead.","Whether Sushruta has a parallel to this category. No Sushruta passage was retrieved for this record, so no judgement is offered either way. Bhishagratna's translation is public domain and quotable, so this is a gap that a later pass can close rather than a permanent limit.","Whether the clinical construct of sensory overload, as used in autism and sensory processing research, is a genuine adjacent literature for atiyoga or merely a verbal resemblance. That literature was deliberately not reached for: the construct measures a person's response rather than an exposure dose, which is a different object from atiyoga, and asserting the adjacency without retrieving and reading it would repeat the error this revision is correcting.","What a search wider than the one recorded in the modern array would return. Diacritic transliterations, hyphenated and space-separated variants, Devanagari, the AYUSH Research Portal, DHARA and Google Scholar were not searched, so the record's statement about indexing is a statement about four transliterations in two databases on one date and nothing more.","Whether Kaviratna's aphorism numbering offset holds outside the passage checked.

The classical statements are real, locatable and verse-numbered, and they are internally coherent: like increases like and unlike decreases it (Ca.Su.1.44-45), disease as disequilibrium and treatment as whatever restores it (Ca.Su.9.4-5), four participants (Ca.Su.9.3), three modalities (Ca.Su.11.54), three routes (Ca.Su.11.55), six therapeutic measures (Ca.Su.22.4, 22.9-11), dose and application as the hinge between medicine and poison (Ca.Su.1.124-126), and an outcome-defined criterion for what counts as the right medicine at all (Ca.Su.1.134). The corpus also argues with itself about whether treatment changes outcomes (Ca.Su.10.3-5), and scopes its own efficacy claim to curable disease rather than asserting it universally.\n\nWhat the record did not find is an operationalised version of these rules. None of the indexed literature searched, which means the PubMed searches recorded in gatheringNotes and nothing wider, states the rule set as explicit decision criteria. That is a statement about what these searches returned, not about the field: Ayurvedic clinical-decision-support encodings and the AYUSH and CCRAS Standard Treatment Guidelines are not PubMed-indexed, were not searched, and could confirm or refute it. See notKnown and gatheringNotes.\n\nOn the modern side there are now two trials of individualised selection and one reliability study. Kessler 2018 (PMID 29426006) randomised 151 knee osteoarthritis patients to individualised multimodal Ayurveda against conventional conservative care and found a significant WOMAC difference favouring Ayurveda, sustained at 12 months, but open-label and against conventional care rather than against a fixed Ayurvedic regimen. Furst 2011 (PMID 21617554) was double-blind and double-dummy but a 43-patient pilot with no placebo-only arm, and found no efficacy difference from methotrexate. Neither isolates the individualisation rule: both compare an individualised Ayurvedic arm against a non-Ayurvedic comparator, so a result in either direction is consistent with the selection rule contributing nothing. The secondary analyses of the 2018 trial (PMID 35683435) conclude that the therapeutic effects cannot be explained by the therapies themselves alone.\n\nReliability has been measured once, for diagnosis rather than for treatment selection. Kessler 2019 (PMID 30653338) had 4 Ayurvedic experts diagnose the same 30 patients and found largely fair-to-poor kappa for central diagnostic entities including prakriti and agni, despite 95% agreement on the consented final diagnosis. That result matters more to this record than its size suggests: prakriti and agni are inputs to most dose and modality decisions, so unreliable inputs make a determinate output harder to claim. No study measuring agreement on the resulting treatment plan was found.\n\nThe rest of the indexed literature retrieved on treatment principles consists of narrative and methodological essays which restate the classical scheme in modern vocabulary, argue that the RCT is the wrong instrument for it, and stop. No biomarker and no validated instrument for bala, or for any other step in the decision chain, was found in the searches recorded in gatheringNotes.","summary":"Chikitsa sutra is the classical Ayurvedic label for the set of rules a physician is supposed to apply when deciding what to do for a given patient, as distinct from the list of drugs used. The core claims are that disease is a disturbance of equilibrium among the bodily constituents, that treatment is whatever restores that equilibrium, that treatment succeeds only through the joint adequacy of four participants (physician, drug, attendant, patient), and that the same substance is medicine or poison depending on dose, timing, route, the patient's strength and the state of the doshas. Underneath these sits the samanya-vishesha rule (Ca.Su.1.44-45), that like increases like and unlike decreases it, which is what makes 'treat with the opposite' a rule rather than a slogan. Charaka sorts therapeutics into three modalities (invocatory/daiva, reasoned/yukti, mental restraint/sattvavajaya) at Ca.Su.11.54 and into three routes (internal, external, surgical) at Ca.Su.11.55, and at Ca.Su.22 sets out six therapeutic measures (langhana, brimhana, rukshana, snehana, svedana, stambhana) as the frame within which treatment is chosen. Charaka also argues, at Ca.Su.10, over whether treatment makes any difference at all. The tradition presents all of this as decision rules, but they are stated as maxims, and none of the classical passages retrieved for this record reduces them to an explicit, testable algorithm.","contested":[{"question":"Is chikitsa sutra a genuine decision procedure or a post-hoc rationalisation of choices made on other grounds?","positions":["Ayurvedic academic writing treats it as a determinate rule set that a trained physician applies to reach a defensible plan from nidana onward.","Methodological critics inside the field (for example the 'Rishi principles' essay, PMID 24459385) concede the selection is not reducible to stated criteria and argue the appropriate response is to change the research method rather than to specify the rule.","The one piece of agreement data found bears on the inputs rather than the output and favours the second position: Kessler 2019 (PMID 30653338) had 4 experts diagnose the same 30 knee osteoarthritis patients and found fair-to-poor kappa for prakriti and agni, with better agreement on disease-related than on constitutional entities. Its 95% figure is agreement on a consensus diagnosis reached by nominal group technique, not independent agreement, so it should not be read as supporting the first position.","Neither position has been tested on the thing actually in dispute. No study was found measuring whether physicians who agree on a diagnosis then agree on a treatment plan, which is where a decision procedure would show itself."]},{"question":"What is the correct relation between hetu-viparita (opposite to cause) and vyadhi-viparita (opposite to disease) when the two point to different measures?","positions":["TRANSLATOR'S VOICE, AND SECOND-HAND, BUT QUOTED. Bhishagratna, in his own Introduction to Sushruta Vol. I under the heading 'Principles of Ayurvedic Treatment' (printed page lx, running head page 110-111), writes that 'Ayurvedic physicians practically recognise two different sets of principles in the domain of practical therapeutics, which may be stated in the terms of their western colleagues as Laws of Similars and Contraries', and appends a footnote listing six categories: 'Similar in character to the exciting factors of a disease - Similar in character to the Esse of a disease - Similar in character both to the exciting factors and Esse of a disease. Contrary in character to the exciting factors of a disease. Contrary in character to the Esse of a disease.

Three limits, stated because this project has absorbed a translator's voice as doctrine three times. It is Bhishagratna writing in 1907, not Sushruta. The locus he gives, Madhava Nidana I.8, was NOT retrieved, so that address is his attribution and not this record's. And he explicitly declines to resolve the conflict, saying the apparent contradiction 'has been fully accounted for and explained in the writings of the latter day commentators, but it does not fall within our province to enter into these disquisitions', so he is evidence that the scheme exists and the tie-break is commentarial, not evidence of what the tie-break is.","The commentarial tradition is reported to hold that both, plus ubhaya-viparita (opposed to both), are legitimate and that the physician selects by which target is dominant.

Reliability has been measured once for DIAGNOSIS, not for treatment selection: Kessler 2019 (PMID 30653338) found largely fair-to-poor inter-rater kappa for prakriti and agni across 4 experts and 30 knee osteoarthritis patients. No study measuring agreement on the resulting treatment plan was found in the searches recorded in gatheringNotes.","Whether individualised selection outperforms a FIXED Ayurvedic protocol for the same condition. This narrow gap survives the two trials the record now carries, because both compare an individualised Ayurvedic arm against a non-Ayurvedic comparator: Kessler 2018 (PMID 29426006) against conventional conservative care, Furst 2011 (PMID 21617554) against methotrexate. No trial found randomised patients between individualised and standardised Ayurvedic treatment, which is the comparison that would isolate the selection rule.","How 'bala' (strength of patient and of disease), on which most dose and modality decisions turn, is to be measured. No validated instrument was found. Kessler 2019's poor kappas for agni and prakriti suggest the same problem affects the other constitutional inputs.","Whether the three-modality classification (daiva / yukti / sattvavajaya) carries any predictive content, or is purely taxonomic.","What the actual decision weights are when dose, timing, season, constitution and disease stage give conflicting indications. The passages this record carries assert that the physician balances them but do not say how.","Whether the 'poison and medicine' maxim of Ca.Su.1.124-126 corresponds to any measured dose-response or therapeutic-index data for the classical formulations it is applied to.","NIDANA PARIVARJANA IS UNCITED IN THIS RECORD. The record lists removal or avoidance of the causative factor as a component of chikitsa sutra, because it is standard terminology in the secondary literature, but no classical passage for it was retrieved. Searches of the Kaviratna Charaka text for 'avoidance of the cause', 'removal of the cause', 'abstention from the cause' and similar phrasings returned nothing, which is a fact about those search strings and that translation, not about the corpus. The record also no longer asserts that nidana parivarjana is the first measure or prior to any drug, which was an unsourced claim about priority on top of an unsourced component.","THE VIPARITA TRIAD AND VIPARITARTHAKARI ARE UNCITED IN THIS RECORD. The general principle that like increases like and unlike decreases it is cited and quoted (Ca.Su.1.44-45). The commentarial triad hetu-viparita / vyadhi-viparita / ubhaya-viparita is not, nor is viparitarthakari, the separate notion that a measure nominally similar in quality may act oppositely in effect. Both appear in the secondary literature; neither is addressed to a text here, and the second contested item consequently cannot be checked from this record. UPDATED 2026-10-06: the six-fold similar/contrary scheme to which the triad belongs is now attested in one quotable source, Bhishagratna's own Introduction to Sushruta Vol. I (printed page lx), which lists the six categories and attributes them to Madhava Nidana Ch. I v. 8. That is a translator writing in 1907 citing a text this record has not retrieved, so the primary locus of the triad remains unverified and Madhava Nidana I.8 is not asserted here as an address. What is now known is that the scheme is real and pre-modern; what is still not known is where it is stated in a text this record can quote, and what the tie-breaking rule is.","ASHTANGA HRIDAYA SUTRASTHANA 14 IS UNREAD. The record carries a chapter-level address for Vagbhata's two-fold therapeutic scheme and nothing more. No text of the chapter was retrieved and no translation of it was found that this project can quote, so the record asserts nothing about what the chapter says or how it numbers its verses. Vagbhata's compression of treatment into nourishing and reducing classes is therefore absent from this record except as it is independently attested in Charaka at Ca.Su.22.","CHARAKA SUTRASTHANA 23 IS ADDRESSED ONLY AT ITS OPENING AND ITS CLOSING SUMMARY. The record quotes Ca.Su.23.3-23.5a on the causes of santarpana-induced disease, and the chapter's closing summary verse, Ca.Su.23.40, is quoted inside that entry's establishes. The apatarpana half of the chapter, the disease lists and the remedies prescribed for each class were read in the scan but are not recorded here, and no verse numbers are asserted for them.","SEARCH GAP, NOT AN EVIDENCE GAP: the non-indexed regulatory and institutional literature was not searched. AYUSH and CCRAS Standard Treatment Guidelines, the Ayurvedic Pharmacopoeia of India, state board curricula and any Ayurvedic clinical-decision-support encodings are outside PubMed and were not retrieved for this record. This is the material that would confirm or refute the claim that no published work states the rule set as explicit decision criteria. Until it is searched, this record's negative finding about explicit decision criteria is bounded to the indexed literature and must not be read as a statement about the field.","Whether the individualisation in the one large trial was doing any work. The trial's own secondary analyses (PMID 35683435) conclude that the therapeutic effects cannot be explained by the therapies themselves alone, and identify the treatment arm and baseline severity, not the tailoring, as the variables that mattered most in their models. No study was found that decomposes an individualised Ayurvedic intervention into the selection rule and the rest of the package.","Whether the stambhana definition at Ca.Su.22.12a and the five definitions before it were ever meant as an exhaustive classification of therapeutic action. The chapter's own closing summary, Ca.Su.22.44, calls the six 'the six therapies by which treatment proceeds', and Kaviratna's footnote on the chapter adds that however combined, other methods 'cannot transcend the six original methods mentioned in this Lesson'.

Two address corrections, both from reading the verse-numbered Sanskrit rather than trusting the earlier revision's span. First, the six definitions do not end at 22.11. Standard 22.9 covers langhana, 22.10 brimhana and rukshana, 22.11 snehana and svedana, and the stambhana definition is the FIRST HALF of 22.12: stambhanam stambhayati yadgatimantam calam dhruvam| , after which 22.12 continues laghushnatikshnavishadam ruksham sukshmam kharam saram||12||. The span is therefore 22.9-22.12a, and the entry's verse field has been corrected. Second, the closing summary sentence quoted here as the third segment had no address at all in the earlier revision, which gave only 22.4 and the definitions. It is standard 22.44: tatra shlokah- ityasmin langhanadhyaye vyakhyatah shadupakramah| yathaprashnam bhagavata chikitsa yaih pravartate||44||. 22.4 itself was re-confirmed as langhanam brimhanam kale rukshanam snehanam tatha| svedanam stambhanam caiva janite yah sa vai bhishak||4||.

The seven-tissue sequence and the prasada and kitta split are stated plainly in both Charaka and Sushruta, and the upadhatu and mala of each stage are stated in Charaka, so the doctrine is well attested as doctrine. What it lacks is measurement. Nothing retrieved for this record reports a rate at which any tissue is converted into any other, identifies a dhatvagni with an enzyme, organelle or pathway, or describes an experiment that could discriminate between kshira-dadhi, kedari-kulya and khale-kapota; the three models make no differing predictions that any retrieved author has stated in testable form. The searches behind those statements are bounded and named: PubMed esearch on 2026-10-06 for 'dhatu poshana' returned 55 records and all 55 titles were screened; 'dhatvagni' returned 2; 'khale kapota' returned 1 (PMID 32855015); 'kedari kulya' returned 0. Four search strings on one date is not a systematic review and will not support a claim that no such study exists anywhere. Within that set, four of the five references carried here are non-empirical, three narrative or conceptual reviews and one hypothesis paper. The fifth, PMID 24250128, is a randomised placebo-controlled trial of 46 patients whose rationale runs through rakta-dhatvagni, but its endpoints are haematological and the dhatvagni premise is assumed rather than measured, so it does not test the doctrine either. On the commentarial side the three nyayas are not scriptural: searches for kedari, kulya, kapota, khale and dadhi across the full retrieved text of both public-domain translations return only unrelated hits, drug names, pigeon flesh, snake species and colour terms, and none in a tissue-nutrition context, so the nyaya names are absent from the mula texts in these translations and the terminology is attributed by the secondary literature to the medieval commentators. A caution about that secondary literature: papers on these models routinely assert correspondences to absorption, circulation and cellular metabolism, and PMID 26664231 is carried here as a named example, proposing dhatu siddhanta as a probable predecessor of stem cell therapy. Those are restatements of classical doctrine in modern vocabulary, not findings. The honest summary is that dhatu formation is a coherent and internally detailed physiological narrative, disputed at its own foundation on the question of how many fires drive it, with no independent empirical support and no validated modern correlate in the literature retrieved here.","summary":"Ayurvedic physiology holds that food, once digested by jatharagni, yields a nutrient essence (ahara rasa) that is progressively converted into seven bodily tissues (dhatu) in a fixed order: rasa, rakta, mamsa, medas, asthi, majja, shukra. Each conversion is said to be driven by a tissue-specific fire (dhatvagni) and to yield two fractions, a usable portion (prasada) and a waste portion (kitta). Both samhitas assert the sequence, the fire-driven conversion and the prasada and kitta split, and Charaka also names the secondary tissue and the waste product belonging to each stage; neither names a mechanism. How many fires there are, and whether agni is anything other than pitta, is disputed inside the tradition rather than settled by it. The three named nutrition models (kshira-dadhi, kedari-kulya, khale-kapota) do not occur in the mula texts of either samhita as translated by Kaviratna or Bhishagratna; the secondary literature attributes the terminology to the medieval commentators, and no commentary passage for any of the three has been retrieved for this record. Kshira-dadhi (milk-to-curd) reads the sequence as complete serial transformation; kedari-kulya (field-and-irrigation-channel) reads it as a nutrient stream distributed through channels to tissues in order; khale-kapota (threshing-floor-and-pigeons) reads it as each tissue drawing selectively from a common pool. On how long the cycle takes, the texts give figures that are not directly comparable and neither is offered as an observation: Charaka reports, as the view of 'some', six days and nights for one dhatu to become the next, while Sushruta gives 3,015 kalas for each stage and a month for the whole chain, with a month defined in the same chapter as 18,090 kalas. The familiar 'five days per dhatu' is not a statement of either text. It is Bhishagratna's own conversion, printed in his brackets as 'according to our modern computation', and it holds only if the month is taken as thirty days.","contested":[{"question":"How long does the full transformation from rasa to shukra take, and do the two texts actually disagree?","positions":["Charaka Chikitsasthana 15.21 (Kaviratna's 20) reports, as the opinion of 'some', six days and nights for the transformation of ONE dhatu into the next. The figure is per step, and the disciple's objections follow immediately, so it is presented as a held view rather than as settled doctrine.","Sushruta Sutrasthana 14 gives 3,015 kalas for each stage and a month for the whole chain, and the same chapter defines a month as 18,090 kalas, which is six times 3,015.","The familiar 'five days per dhatu' is not in either text. It is Bhishagratna's bracketed conversion, marked in his own translation as 'according to our modern computation'. It follows arithmetically from 3,015 of 18,090 kalas if a month is taken as thirty days, but the text states no absolute length for a kala and performs no such conversion.","The record previously set Charaka's six days against Sushruta's one month and called them conflicting. That comparison was between a per-step figure and a whole-chain figure. Compared per step the two come out at six days against five, which is a narrower disagreement than the record claimed; compared over the chain, six days a step would run to about thirty-six days. Whether that is a real disagreement, two different quantities, or two measurement conventions is not resolved by either text.","Later and secondary literature circulates other figures, commonly 'about a month' or 'six days', without resolving the question.

The reason he then supplies is his, not the text's.","Bhishagratna's Introduction reports Sushruta as holding 'that the Pittam is the only fire present in the system', which if taken strictly leaves no dhatvagni as a separate agent at all.","The same passage reports that 'Agnivesha and certain sections of the Ayurvedic Acharyayas hold that there are five Anjali-fuls of Agni in the human organism', a quantity rather than a count of fires, and Bhishagratna reconciles it with pitta only by his own device.","Arunadatta, commenting on the Ashtanga Hridaya and reported in the same passage, 'holds that there are as many Dhatvagnis as the constituents of the body', which abandons the number seven.","PMID 22131747 records the thirteen-fold scheme, one jatharagni with five bhutagni and seven dhatvagni, as the standard modern presentation, and also documents that the identity of agni with pitta is itself disputed inside the tradition.","All of the above except the Charaka aphorisms reach this record through a translator's Introduction or a modern review.

The names are absent from the mula texts as translated by Kaviratna and Bhishagratna; secondary literature points variously to Dalhana, to Chakrapanidatta and to the Bhavaprakasha Purva Khanda, and no commentary or nighantu passage naming any of them has been retrieved, so none of those attributions is carried as a citation here.","Meulenbeld's A History of Indian Medical Literature is the reference that would settle which commentator originates which nyaya, and it was not consulted. The attribution question above stays open for that reason and not because the question is unanswerable.","The thirteen-agni enumeration, one jatharagni with five bhutagni and seven dhatvagni, is carried here only from the mula-text aphorisms that state its three parts separately (Charaka Chikitsasthana 15.13-15.14, 15.16 and 15.39) and from PMID 22131747. The enumeration is widely attributed to Chakrapanidatta commenting on Charaka Chikitsasthana 15, and no text of that commentary has been retrieved, so the attribution is not asserted and no verse is cited for it.","Whether 'rasa' denotes plasma, chyle, lymph, interstitial fluid, or a composite of these is not settled, and the choice changes every downstream correspondence.","The upadhatu and mala correspondences are now cited to mula text (Charaka Chikitsasthana 15.17-15.19) but they are stated there, not explained: the text gives no reason why bone should yield hair or rasa yield phlegm, and nothing retrieved here examines the question.","One of those correspondences is textually unsettled in the translation this record quotes. Kaviratna divides the last pair as marrow yielding an oily substance and skin yielding the eye secretions, while secondary renderings of the same aphorism assign the oily eye and skin secretion to majja. No standard Sanskrit edition was retrieved to adjudicate, so the record quotes Kaviratna as printed and relies on neither division.","Sushruta's kala is defined in this chapter only as one part in 18,090 of a month. No independent definition of its absolute length was found, so 'five days per dhatu' holds only on the assumption that the month in question is thirty days.","It is not known whether Charaka's reported six days a step and Sushruta's 3,015 kalas a stage reflect two different processes, two measurement conventions, or simple disagreement.","Vagbhata's compressed restatement of tissue increase and decrease at Ashtanga Hridaya Sutrasthana 11 is not covered here.

The classical rationale actually retrieved is of two kinds: a stated purpose and a habituation principle in Charaka (the aim of the discipline is protection of the health of the healthy; okasatmya makes a practice tolerable; observing the practices of the good secures health and self-restraint together), and, in a separate chapter on seasonal regimen, Sushruta's parallel between the parts of the day and the seasons of the year with the doshas cycling within the day. That parallel has not been operationalised into a measurable prediction in anything this record consulted, and no passage retrieved here derives any daily act from it. On the modern side this record's base is narrow and should not be read as speaking for the regimen: it is three oral-hygiene references and one abhyanga pilot, covering three of seventeen enumerated limbs, with the per-limb breakdown and the bounds of the search set out in modernCoverage. Within that base: oil pulling has a systematic review of randomised trials finding a probable small benefit at very low certainty and inferior performance to chlorhexidine; tongue scraping had a Cochrane review resting on 40 participants which has since been withdrawn; abhyanga has one uncontrolled 20-person pilot.

A reader should treat dinacharya as a coherent and internally argued traditional hygiene and self-care protocol whose individual components range from plausibly useful on general grounds (oral hygiene, moderate exercise, regular bathing, regular sleep) to uncovered by anything in this record, and whose distinctive claims, that the ordering and timing matter and that the practice prevents disease through doshic regulation, are not evaluated by any source cited here.","summary":"Dinacharya is the classical Ayurvedic prescription of a fixed daily sequence of self-care acts, covering oral care including tooth cleaning and tongue scraping, application of oil to head, ears, body and feet, collyrium, medicated smoke and snuff, bathing, exercise in measure, dress, and a code of conduct. The rationale the retrieved classical passages actually give for the regimen is twofold and modest. Charaka grounds it in the stated purpose of the discipline, which is protection of the health of the healthy rather than treatment of the sick, in okasatmya or the habituation that makes a practice tolerable, and in the claim that the practices of the good secure health and self-restraint together. Separately, in his chapter on seasonal regimen rather than in his daily-regimen chapter, Sushruta states a parallel between the parts of a day and night and the seasons of the year, and says the doshas accumulate, aggravate and subside within a day as they do across a year. No passage retrieved for this record derives the daily acts from that parallel, and the two sit in different chapters of Sushruta.

The studies that make that sentence true are named here, with their figures, so that the claim can be checked rather than taken on trust.\n\nPMID 30653338 (Kessler et al. 2019, J Altern Complement Med) nested a reliability study of 30 knee osteoarthritis patients and four Ayurvedic experts inside a randomised controlled trial. Raw agreement was high, 95 percent consensus agreement on the main diagnosis, and the chance-corrected figures were not: the abstract reports kappas that \"largely yielded fair-to-poor inter-rater agreement kappas for central diagnostic aspects such as prakriti and agni (kappa values between 0 and 0.4)\", and adds that \"agreement on disease-related entities was better than that on constitutional entities\". PMID 24191170 (Kurande et al. 2013, Evid Based Complement Alternat Med) had fifteen registered Ayurvedic doctors with 3 to 15 years of experience independently examine twenty healthy subjects, and computed weighted kappa for all 105 doctor pairs: average pairwise kappa was 0.07 for pulse, 0.17 for tongue and 0.28 for prakriti, with the null hypothesis of random rating rejected for only twelve of the 105 pairs on prakriti, one pair on pulse and no pair on tongue. That study's own qualification has to travel with those numbers: it also found \"significant evidence against random rating by software and questionnaire use\" and concluded that \"Prakriti assessment appears reliable when questionnaire and software assessment are used, while other diagnostic methods have room for improvement\". The unflattering result is therefore about unaided expert judgement, not about every instrument, and this record does not claim more than that. PMID 23930037, the same group's methodological overview, gives the field's assessment of itself in 2013: \"reliability studies in Ayurveda are in the preliminary stage\".\n\nWhat none of the three measures is the classificatory axes this record is about. Between them they cover pulse, tongue, prakriti, agni and a final named diagnosis in one condition. No located study reports an agreement figure for assigning a disease to nija or agantu, to sharira or manasa, to a doshaja subtype, to one of the 80, 40 and 20 nanatmaja lists, or to one of Sushruta's seven bala-pravritta types. The classificatory schemes themselves are well documented in the primary texts and can be reported with confidence as doctrine; what remains unmeasured is whether two physicians apply them the same way.\n\nOn prediction the record states only what it has looked for. A PubMed search on 2026-10-06 for ayurved*[tiab] AND (classification[tiab] OR nosolog*[tiab] OR vyadhi[tiab]) AND (prognos*[tiab] OR predict*[tiab] OR \"treatment response\"[tiab]) returned 24 records whose titles were screened, and none of them tests whether assigning a disease to an Ayurvedic class predicts treatment response or prognosis better than the symptom description the assignment is derived from. That is a keyword search on title and abstract and would miss a study that does not use those words, so it supports \"none located\" and not \"none exists\".\n\nInstitutionally the picture has moved faster than the evidence, and this project now holds the artefact. The sibling repository file data/enrichment/icd-tm2.json in ayurveda-atlas is a snapshot of the ICD-11 TM2 content at release 2026-01, fetched 2026-09-17, containing 709 entities, 61 blocks and 648 categories. Five blocks bear directly on Ayurvedic disease classification: \"Functional elements and humoral derangement patterns (TM2)\", \"Physical constituent derangement patterns (TM2)\", \"Power derangement and chronic accumulation patterns (TM2)\", \"Body constitution and temperament patterns (TM2)\" and \"External factors disorders (TM2)\". Two facts about that chapter matter more than its size. The first is that its statistical standing is narrower than the word classification suggests: PMID 41180267 describes Chapter 26 as \"a supplementary, morbidity-only chapter, enabling dual coding of traditional medicine concepts alongside conventional diagnoses\", with dual coding \"optional\", Module I in force from 1 January 2022 and \"Module II (Ayurveda, Siddha, Unani) was added in 2025\". Morbidity-only means the codes are excluded from mortality statistics; the same source says Chapter 26 carries \"the potential to support morbidity statistics\", so it is not correct to say TM2 is excluded from morbidity statistics too. The second is that the pattern-level categories were adopted ahead of their own validation: the same source states that \"The validity and reliability of Chapter 26 require dedicated study\", that \"Within-system reliability should be tested through interrater and test–retest assessments among traditional medicine clinicians\", and that \"validity is not guaranteed: even within the same system, different practitioners may not agree when assigning traditional medicine patterns\". A bounded PubMed search on 2026-10-06 for \"ICD-11\"[tiab] AND (\"traditional medicine\"[tiab] OR ayurved*[tiab]) returned 19 records, titles screened, none of which reports field-testing or coding-reliability results for the ASU module. NAMASTE (PMID 37541078) stands on the same footing: the initiative report establishes that standardised ASU morbidity codes exist and who built them, not that the categories behind them have been validated or that coders apply them reliably.\n\nThe constitution-genomics literature does not close the gap, and this record says so explicitly rather than omitting it while neighbouring records cite it. PMID 18782426 (Prasher et al. 2008) and PMID 26511157 (Govindaraj et al. 2015) are the two most-cited molecular results in the field. Both classify persons, not illnesses: Prasher profiled healthy individuals of extreme vata, pitta and kapha type and framed the conclusion as \"differential disease predisposition\", a hypothesis about susceptibility in the well, while Govindaraj correlated 52 SNPs with prakriti group membership in 262 screened males. Neither assigns a disease to a class, neither tests whether such an assignment is reproducible, and neither tests whether it predicts anything. Transfer to disease classification would require the disease axes to be derived from or validated against constitution, and the texts do not derive them that way: nija and agantu, sharira and manasa, and the doshaja triad classify the disturbance, not the person, and prakriti is the baseline a vikriti is read against rather than the vikriti itself. The one empirical hint about how the two levels behave points away from transfer, since PMID 30653338 found agreement on disease-related entities better than on constitutional entities. A replicated genomic correlate of prakriti would therefore still license no claim about vyadhi-vibhaga.\n\nThere is also a textual problem that no amount of modern work addresses: Charaka and Sushruta each give more than one classification, the schemes are structurally incompatible, both authors then subordinate everything to the doshas on grounds that are stated in unfalsifiable terms, and the identification of the enumerated Sanskrit disease names with modern entities was flagged as unreliable by the public-domain translators themselves.","summary":"Ayurveda does not use one disease taxonomy but several overlapping axes applied to the same illness at once. Charaka sorts diseases by origin into nija (constitutional, arising from vitiated dosha) and agantu (accidental, arising from trauma, poison, spirits, weapons or curses); by seat into sharira (bodily) and manasa (mental); by dosha into vataja, pittaja and kaphaja, with stated counts of 80, 40 and 20 nanatmaja disorders; and by the numeric enumerations of the Ashtodariya chapter, which tallies named diseases by the number of their varieties. Sushruta gives a four-way origin classification (agantuka, sharira, manasa, svabhavika) in the opening chapter and, in the chapter on the classification of diseases, a seven-way scheme running from parental-seed defect through congenital, doshic, traumatic, seasonal, providential and spontaneous causes, which he maps onto the older three-fold adhyatmika, adhibhautika and adhidaivika division. Across all of these Charaka asserts a unifying claim: however classified, constitutional disease never escapes vata, pitta and kapha.","contested":[{"question":"How many classifications are there, and which is primary?","positions":["Charaka Sutra 11.44 gives three (physical, accidental, mental).","Charaka Sutra 20.2 gives four (accidental plus the three doshaja) and then immediately gives two by cause and two by substratum.","Sushruta Sutra 1 gives four (agantuka, sharira, manasa, svabhavika).","Sushruta Sutra 24 gives seven bala-pravritta types mapped onto three older ones.","The texts present these as complementary; they are not structurally reconcilable, and which is treated as primary varies by author and by clinical context."]},{"question":"Is the nija/agantu distinction stable?","positions":["It is presented as the fundamental causal division.","Charaka himself states in Ashtodariya that each converts into the other on aggravation, and in Maharoga that all four classes follow one another when aggravated, which means the distinction holds only early in the course.","Since both classes are said to share the same three inducing causes (Sutra 20.9), the distinction rests on the proximate agent alone."]},{"question":"Are the nanatmaja counts of 80, 40 and 20 a taxonomy or a mnemonic?","positions":["Traditional exposition treats the lists as exhaustive enumerations of dosha-specific disorders.","Kaviratna noted that the lists differ between printed editions and that he compiled his from two texts, and that identification of the names with modern entities may not be accurate in every instance.","Some scholars read the numeric enumerations of Ashtodariya and Maharoga as pedagogical devices for memorisation rather than as claims about the number of diseases."]},{"question":"Should Ayurvedic categories be mapped into ICD, or kept separate?","positions":["The NAMASTE and ICD-11 traditional medicine module position is that standardised coding enables morbidity statistics, insurance and research on traditional medicine.","The ethnopharmacology methodological position (Staub and colleagues 2015) is that forcing indigenous categories into a clinical-examination-based biomedical taxonomy destroys exactly the categories that carry the local explanatory content, and that patient-perception-based systems such as ICPC map better.","The practitioner-side critique visible in the ICD-11 Chapter 26 revision literature is that even a harmonised traditional classification satisfies none of the traditions it merges."]},{"question":"Does a classification that always terminates in the doshas classify anything?","positions":["The classical position, stated in Charaka's bird-and-shadow verse and in Sushruta's fatherhood-of-all-maladies verse, is that doshic reduction is the deepest truth about disease.","The criterion Sushruta actually offers, that doshic symptoms can be detected in a disease of whatsoever type, is not falsifiable as stated, so the reduction cannot be tested by the means the text provides.","Charaka's own reservation, that agantu disease is initially distinguished therefrom, preserves a class that is not doshic in origin."]},{"question":"Does the constitution-genomics line bear on disease classification at all?","positions":["The ayurgenomics position, as stated in Prasher et al. 2008 (PMID 18782426), is that Ayurvedic phenotypic classification \"allows us to uncover genes that may contribute to system level differences in normal individuals which could lead to differential disease predisposition\", and in Govindaraj et al. 2015 (PMID 26511157) that \"the phenotypic classification of India's traditional medicine has a genetic basis\". Both claims are about prakriti.","This record's position is that the claims do not transfer to vyadhi-vibhaga, because the classified object differs: prakriti classifies the person and is assessed in the healthy, while the axes in this record classify the illness.

The compound dosha-dushya-sammurchana was not found in the mula text of either Samhita, and this revision stopped trying to make up for that by pointing at doctrines that are attested under other names.\n\nThe term's advertised addresses do not survive retrieval. The 2025 JAIMS review that is the principal English-language treatment gives two: Charaka Chikitsasthana 28/20-23 and Sushruta Sutrasthana 15/18. Both were retrieved. The Charaka passage is a running list of the signs produced by aggravated vata, closing with the line that aggravated vata produces signs of these kinds. The Sushruta verse states that an excessively increased dhatu increases the one after it, so that reduction of over-increased dhatus is beneficial, and Bhishagratna prints it as metrical text in the same sense. Neither passage speaks of dosha combining with dushya. Other addresses circulate (Charaka Nidana 1, Charaka Vimana 5/3, Ashtanga Hridaya Nidana 1, Ashtanga Samgraha, Madhava Nidana, Sushruta Sutra 21) and were not all retrieved; the mutual inconsistency of the set is the point, and it is recorded in contested rather than resolved.\n\nWhat is attested, and what each attestation is for. Sushruta Sutra 21 gives sthana-samshraya and the site-specific disease lists. Charaka Sutra 28 gives the same site-specificity principle with a tissue-by-tissue list. Sushruta Sutra 21/29-30 and Charaka Sutra 28/31-33 give lodgement and latency, which is the classical material behind the modern khavaigunya doctrine. Charaka Nidana 4 makes the manifestation, non-manifestation or partial manifestation of disease depend on the particular characteristics of nidana, dosha and dushya together, and states that unless the three unite in sequence and with force the disease does not appear, or appears late, weakly or partially. Charaka Vimana 6/7 makes the variety of diseases a function of the difference of the exciting cause and the difference of the dushya. Each of those is cited here under the name its own sources use, and each carries attestsCompound: false. The compound does not inherit their standing, and a reader who wants the textual case for site specificity should go to them and not to this headword.\n\nOn the word itself: saṃmūrcchita does occur in Charaka, at Sutra Sthana 24/48 in the Trikamji-based text retrieved, of various strong liquors commingled, which Gangadhara glosses as militāni, 'mixed'. That is a pharmaceutical sense. The dictionaries give the noun saṃmūrchana as congealing, thickening, accumulating, spreading, and as fainting or insensibility. The pathological-union sense is supplied by modern Ayurvedic usage, and mūrchana in Rasa Shastra and in oil and ghee pharmacy is a third thing again.\n\nEmpirically the concept is untested. There is no operational criterion for declaring that sammurchana has occurred in a given patient, no measurement of whether clinicians agree on which dushya is involved, no marker of khavaigunya, and no prospective demonstration that an assigned dosha-dushya pair predicts anything. The literature located consists of narrative reviews in non-indexed or low-indexed Ayurvedic journals (the papers that dominate this topic appear in JAIMS and similar outlets with DOIs but no PubMed indexing), one 1989 uncontrolled biochemical correlation study, and reliability and consensus studies whose results are unfavourable. PubMed returned nothing for the compound in the term-record pass, which is a finding about that string in that index.\n\nA reader should treat dosha-dushya-sammurchana as explanatory vocabulary for site specificity: not a mechanism that has been demonstrated or measured, and not a classical term.","summary":"Dosha-dushya-sammurchana is a compound used in modern Ayurvedic teaching and journal writing for the step at which a disturbed, circulating dosha is said to meet and combine with a susceptible tissue element (dushya) at a particular site, so that a specific disease takes form there rather than anywhere else. The compound, not the mechanism, is what this record is about, and its textual standing is weak. The 2025 JAIMS review that is the principal English-language treatment of the term gives two classical addresses for it, Charaka Chikitsasthana 28/20-23 and Sushruta Sutrasthana 15/18. Both were retrieved. The Charaka passage is a list of the signs produced by aggravated vata; the Sushruta verse is the rule that an excessively increased dhatu increases the one after it, so that reduction is beneficial. Neither speaks of a union of dosha with dushya. What is securely classical are separately named doctrines that cover much of the same ground and can be quoted from public-domain translations: sthana-samshraya in Sushruta Sutrasthana 21, where the same spread doshas produce gulma in the abdomen, prameha in the bladder, kushtha in skin and blood and granthi or arbuda in fat according to where they are 'incarcerated'; the tissue-by-tissue list at Charaka Sutrasthana 28; and the Charaka passages that make the manifestation of disease depend on the particular characteristics of nidana, dosha and dushya taken together (Nidanasthana 4) and on the difference of the dushya vitiated (Vimanasthana 6). Those doctrines carry their own names and their own records in this lexicon. In modern teaching the step named by this compound is placed at the sthana-samshraya stage of shat-kriyakala and paired with khavaigunya, the notion of a pre-existing local defect in a channel, which is itself a commentarial and textbook term rather than a phrase with a retrievable Samhita verse.","contested":[{"question":"Where does the compound 'dosha-dushya-sammurchana' come from?","positions":["Modern reviews present it as a classical Ayurvedic concept and cite Samhita verses for it.","The cited verses differ between reviews and none of them contains the compound as a defined term: a 2025 JAIMS review cites Charaka Chikitsa 28/20-23 and Sushruta Sutra 15/18, other sources point to Sushruta Sutra 21 or to Ashtanga Hridaya Nidana 1. The pattern is consistent with a later scholastic or textbook coinage summarising a classical principle rather than a Samhita term.","The two addresses the JAIMS review gives were retrieved and are about other subjects, which moves this from a pattern argument to a checked result for those two loci.

The khavaigunya requirement is an added explanatory layer, not a quoted premise.","Charaka Nidana 4 states a different condition again: not a defect at the site, but a joint requirement on nidana, dosha and dushya, with a predominance strong enough for manifestation. The three accounts are not the same claim and the sources do not reconcile them."]},{"question":"Is dosha alone sufficient, or is a susceptible dushya necessary?","positions":["The sammurchana doctrine holds that disease requires the combination; dosha in a healthy tissue passes without producing disease.","This is difficult to reconcile with classical statements elsewhere that disturbed dosha permeating the whole system produces fever and generalised disease. The sources do not explain what makes a dushya susceptible or how susceptibility could be detected in advance.","Charaka Nidana 4's conjunction requirement is the strongest classical support for the first position, and it still does not say what makes a dushya susceptible, only that the characteristics of the three factors must coincide."]},{"question":"What does sammurchana mean?","positions":["Modern Ayurvedic usage: the pathological union, intermixing or fusion of disturbed dosha with a susceptible tissue. Some writers gloss it as alivyapti, intermixing.","The Sanskrit dictionaries give congealing, thickening, accumulating, spreading, and fainting or insensibility; Monier-Williams has no pathogenesis sense.","The one occurrence located in a Samhita mula, Charaka Sutra 24/48, uses sammūrcchitāni of strong liquors commingled, glossed militāni by Gangadhara.

THE PREMISE. That human physiology varies with season and with time of day is supported by work outside Ayurveda. Dopico and colleagues 2015 (PMID 25965853) found seasonal expression in peripheral blood mononuclear cells and in adipose tissue across several cohorts, and Wucher and colleagues 2023 (PMID 36745672) found day-night and seasonal expression differences across many tissues in a different design. That is the limit of what those papers do for this record. THE DOCTRINE. Kala-parinama is not the claim that physiology varies with time. It is the claim that time-transformation is one of three general causes of disease, operating through season-specific dosha accumulation, aggravation and subsidence, and correctable by season-specific regimen. Neither Dopico nor Wucher measured a dosha, tested the six-ritu partition, tested the morning-noon-evening kapha-pitta-vata sequence, or evaluated any ritucharya prescription. Citing them in support of the doctrine would be borrowing the credibility of a literature that never tested it, and the earlier version of this paragraph did exactly that: it said the premise was 'independently and robustly established' and then let that sentence stand as the evidential footing for the whole category. It is not. A separate inference has to be blocked too. Several conditions have well-documented seasonal incidence, including cardiovascular events, respiratory infection and affective disorder. Establishing that a disease is seasonal does not establish the mechanism the texts assign to it. A seasonal incidence curve is consistent with the classical dosha assignment, with pathogen ecology, with indoor crowding, with vitamin D, with temperature effects on vascular tone, and with several other accounts at once, and it discriminates between none of them. The record makes no claim that any seasonal disease pattern supports the dosha-seasonal mechanism. WHAT THE PREMISE ITSELF WILL NOT CARRY. 'Robustly established' was also too strong for the seasonal-transcriptomics result taken on its own terms, and the strongest objection is in the primary paper. Dopico and colleagues state in their own abstract that the seasonal change in blood cell composition 'could explain the gene expression periodicity', and in their discussion that the PBMC transcriptional landscapes 'appear to be predominantly driven by annual changes in the cellular composition of blood'. On the authors' own reading, much of the headline signal is a shift in which cells are in the sample rather than a seasonal programme inside a given cell. They also report fewer seasonal genes and a less similar seasonal pattern in their Icelandic donors, and write that 'the impact of living at higher latitudes requires further exploration'. So the premise is supported, and it is supported with live internal caveats about cell composition and about latitude. Wucher and colleagues 2023 is a useful second design because it works from postmortem tissue rather than from circulating PBMCs, and so is not exposed to the same blood-composition confound; it is exposed to others, which its entry records. THE DOCTRINE'S OWN EVIDENCE. On the specific content of kala-parinama, the searches run for this record (described in gatheringNotes) located two narrative reviews, one ethnographic study, one small cross-sectional study of season and constitution against lipids, one randomised open-label trial of a ritucharya-derived intervention (PMID 33935439), one registered single-arm protocol for seasonal purification with no results yet (PMID 42748372), and one cross-sectional survey bearing on the daily-time limb (PMID 42519781). On that set: the one randomised trial tests a single seasonal adjuvant in one season in one region against no-treatment control, open-label, n=60, with disease-frequency and quality-of-life endpoints, which is evidence about that preparation in that setting and not about the six-ritu scheme, the dosha-seasonal mechanism, or ritucharya as a system. The protocol paper is a protocol: single-arm, no control, explicitly 'hypothesis-generating'. The record does not claim that this is the whole literature. It is what the searches named in gatheringNotes returned, and a bounded search cannot support a statement that nothing else exists. What the record does claim is that it located nothing that tests the dosha-seasonal mechanism itself, and the specific gaps are itemised in notKnown rather than summarised away here. A LAST POINT ABOUT THE CATEGORY. Within the classical scheme, time absorbs both the genuinely periodic (intermittent fevers, seasonal illness) and the residual (idiopathic disease, ageing, death), so the category does explanatory work as a default attribution as well as a causal one, and the two uses are not separated in the sources. That is a structural observation about the texts, not an evidential claim, and it is the one thing in this paragraph that does not depend on the modern literature at all.","summary":"Kala-parinama is the Ayurvedic category for disease caused by time. It covers three distinguishable things that the texts run together: the seasonal cycle and its abnormalities, the internal clock of the day, night and digestive phases, and the irreversible ripening of the organism into old age and death. Charaka names time as one of the three general causes of disease and states that its pathological forms are the same three as for any other cause, namely deficiency, excess and perversity of the expected seasonal character. In the epidemic chapter Charaka ranks time as the most potent of the four collective vitiating factors, on the practical ground that a person can leave a place or avoid a water source but cannot step out of the season. Sushruta gives time its own disease class, kala-bala-pravritta, subdivided according to whether the season behaves naturally or contrarily. Charaka also treats the effects of pure ripening, decrepitude and death, as a subclass that has no remedy.","contested":[{"question":"Which mechanism does time act by?","positions":["Charaka Sutra 6 gives a physical mechanism: solar desiccation and lunar or rain-driven moistening acting on the whole environment and thence on the body.","Charaka Vimana 3 gives an astral and moral mechanism: perverse conditions of constellations, planets, sun, moon and wind, rooted ultimately in collective adharma.","Sushruta Sutra 24 gives a narrowly meteorological mechanism: variation of atmospheric heat and humidity, with no astral or moral element.","These are not reconciled in the sources, and modern Ayurvedic writing usually silently adopts the Sushruta version."]},{"question":"Is ageing and death a disease category or an exclusion from it?","positions":["Charaka Sharira 1.122 says decrepitude and death come naturally and that what nature brings about has no remedy, which excludes them from therapeutics.","Sushruta Sutra 24 classes them as a disease type, svabhava-bala-pravritta, and then splits them into timely and untimely, which makes the untimely form modifiable by conduct.","The rasayana literature elsewhere in Charaka treats ageing as at least partly modifiable, which sits uneasily with Sharira 1.122."]},{"question":"Is time a coordinate cause or the dominant one?","positions":["Sutra 11.43 presents the three general causes symmetrically.","Vimana 3.13 ranks time above place, water and air, but the argument given is unavoidability of exposure rather than strength of effect, which is a different claim.","Sharira 1 subordinates time to prajnaparadha by making faults of the understanding the root of the epidemic chain."]},{"question":"How many seasons, and whose calendar?","positions":["The six-ritu scheme is tied to a north Indian lunisolar calendar with a monsoon.","The same scheme is applied without adjustment in temperate, equatorial and southern-hemisphere settings in contemporary practice and in the reviews, with no discussion of whether the mapping survives transplantation.","Sushruta's criterion, natural versus contrary seasonal features, is calendar-independent in principle but is not operationalised anywhere."]}],"notKnown":["Whether any measured human rhythm corresponds to the classical morning-kapha, noon-pitta, evening-vata clock.

The record located no such follow-up in purified subsets. Added in the 2026-10-06 revision, because the record previously carried the premise without this caveat.","Whether any independent reanalysis or formal methodological critique of the human seasonal-transcriptomics literature has been published. The searches run (PubMed, terms combining seasonal and transcriptome or gene expression with deconvolution, cell composition, confounding and reanalysis) returned no such paper, and the strongest objections the record can cite are therefore the primary authors' own. This is a gap in the record's coverage and is stated as one rather than filled with a general remark; it is not a claim that no critique exists.","What the registered seasonal-regimen and seasonal-Panchakarma trial landscape actually contains.

Quoted from the paper: 'Here we find more than 4,000 protein-coding mRNAs in white blood cells and adipose tissue to have seasonal expression profiles, with inverted patterns observed between Europe and Oceania.' The headline proportion belongs to one cohort, not to humans generally: 'Strikingly, we found ~23% of the genome (5,136 unique genes out of 22,822 genes tested) to show significant seasonal differences in expression in the BABYDIET data set.' The hemisphere inversion was seen in asthmatic PBMC samples: 'Summer and winter BABYDIET genes maintained their seasonal expression patterns in the asthmatic PBMC samples, with their patterns inverted in Australia.' The authors also report seasonal change in blood cell counts, and state in the abstract that these changes 'could explain the gene expression periodicity'. In the Gambian cohort the seasonal finding reported is in cell numbers, not in the transcriptome: 'In this data set, seasonal peaks in cell numbers correlated with the rainy season (June to October), during which time the infectious disease burden is at its highest levels.'","quality":"Corrected in the 2026-10-06 revision. Large samples, multiple cohorts, major journal, and the design is sound for its own question. Three things the earlier version of this entry got wrong or left out. First, it said 'roughly a quarter of the human genome shows seasonal expression' as a general result; the ~23% figure is from the BABYDIET cohort alone and is a proportion of the 22,822 genes tested, not of the genome. Second, it described 'a rainy-season-aligned pattern in a Gambian cohort' as if the Gambian result were transcriptomic; the Gambian result reported is seasonal variation in blood cell counts. The hemisphere inversion is Europe versus Australia. Third, and most important, it mentioned seasonal variation in cell composition as an additional observation rather than as the confound the authors themselves identify. The authors write that the PBMC transcriptional landscapes 'appear to be predominantly driven by annual changes in the cellular composition of blood', and that 'although our data suggest that cell-type numbers contribute the majority of seasonal gene expression in PBMCs, future studies of seasonal phenotypic differences within purified immune cell subsets are likely to reveal an additional layer of complexity in the human immune system'. They further note the latitude limit: 'Fewer seasonal genes were identified in Icelandic donors, and common seasonal genes had a less similar seasonal pattern in this data set. If a seasonal photoperiodic clock exists in humans, the impact of living at higher latitudes requires further exploration.' Caveat for honest use, restated and strengthened: this study establishes that season tracks measurable differences in human blood and adipose tissue, and on the authors' reading much of that is cell-composition shift. It says nothing whatever about doshas, about the six-season scheme, or about ritucharya prescriptions. It supports the general premise of kala-parinama and none of its specific content.

That independence is the reason it is here. It is exposed to confounds of its own, which the paper's design makes unavoidable: season and hour of death are not randomly assigned, they correlate with cause of death, with agonal state and with postmortem interval, and the inference runs from time of death to tissue expression rather than from a sampled living rhythm. That reading of the design is the gatherer's, not a statement the authors make. What it does for this record is narrow and should not be stretched: it strengthens the premise that both the daily and the annual cycle leave a measurable trace in human tissue, and it reports that the two cycles are largely distinct from each other, which is at least structurally interesting against a doctrine that runs the same kapha-pitta-vata sequence through the day, the night and the year.

The triguna construct has been genuinely operationalised: multiple psychometric instruments exist and are cited here with resolved identifiers (Vedic Personality Inventory, Wolf 1999, DOI 10.2466/pr0.1999.84.3c.1379; Mysore Triguna Scale, Shilpa and Venkatesha Murthy 2012, SAGE Open, DOI 10.1177/2158244012436564; MHAS-TG, 2025, PMID 40774071), and at least one empirical study has compared guna profiles between diagnosed psychiatric patients and matched controls with plausible results (PMID 36818072). That is more than most concepts in this cluster have. But the instruments do not agree with each other, none is an accepted reference standard, the strongest validation among the papers retrieved here is convergence with another self-report wellbeing questionnaire rather than any clinical outcome, and none of the retrieved papers shows that guna scores predict anything established psychometrics do not already predict. The guna-versus-diagnosis findings are cross-sectional, so they cannot distinguish a stable mental constitution from the current state of an active illness, which is the single question that matters for the classical claim.\n\nThe other body of evidence, on sattvavajaya as therapy, is poor, and the first problem with it is not design but definition. Across the three trials retrieved, sattvavajaya names three different interventions: asana, pranayama, chanting and counselling (PMID 26170589), relaxation techniques (PMID 32398908), and trance or clinical hypnosis (PMID 23049189). A fourth record, the only one on a depressive disorder found in the searches named in gatheringNotes, is a single case report in which sattvavajaya was given together with oral medicines and viddhakarma (PMID 41016220). The trials are small, open-label or unblinded, use unvalidated outcome scales devised for the study, confound the intervention with yoga and counselling, and compare two active arms with no inert control. They report benefit; their designs cannot establish it. The identification of sattvavajaya with psychotherapy, and the comparison with cognitive behavioural therapy, rests in the literature on assertion rather than trial: the most-cited statement of it (PMID 23858273) is a narrative supplement article with no method, no data and no comparison.\n\nWhat this record does NOT say is that sattvavajaya has never been trialled. That claim, in the form the gathering-pass critic quoted, is not in this record and is not made here. What is said instead is bounded: the searches this record can name (see gatheringNotes) returned eleven unique PubMed records for sattvavajaya across two spellings, of which three are the comparative studies cited here, one is the case report, and the remainder are narrative or historical pieces. No controlled trial in anxiety was among them, and no scoping or systematic review in AYU or JAIM was among them. AYU and several Indian Ayurveda journals are not fully indexed in PubMed, so none of this is evidence that such studies do not exist; it is a record of what a named search found.\n\nTwo conceptual points, both now sourced rather than asserted. First, the classical taxonomy of sixteen sattva types is explicitly analogical in the text's own wording, Sha. 4.40 giving the types sattvanukarena, after the manner of the mind of, and classifying by behavioural resemblance to deities, demons and animals; no instrument retrieved here attempts to measure it. Modern triguna work measures three continuous dimensions and drops the sixteen-type scheme, and the classical construct it is in fact closest to is not that scheme at all but the graded sattva sara of Vimana 8 (classical[18]), which the modern literature retrieved here does not cite. Second, the claim that rajas and tamas are doshas of the mind in the same sense that vata, pitta and kapha are doshas of the body has no empirical content in any paper retrieved here. It is not, however, merely a structural parallel asserted and repeated: the nosology chapters added give it mechanical content, with the aggravated bodily doshas obstructing the manovaha srotas to produce unmada (Ni. 7.4) and with sattva destroyed by rajas and tamas named alongside dosha involvement in apasmara (Ci. 10). That content is textual, and it is untested.","summary":"Ayurveda treats the mind (manas) as a substratum of health and disease alongside the body, not as a separate domain. Charaka states that body and mind together are where health and disease inhere (Su. 1.55) and that while vata, pitta and kapha are the doshas of the body, rajas and tamas are the two doshas of the mind (Su. 1.57, Sha. 4.34); Vagbhata states the same twofold locus and the same two mental doshas (AH Su. 1.21). Sattva is not counted among the doshas, and Sharira 4.36 calls the shuddha (sattvika) mind adosha, faultless. It does not follow from this that mental disorder is simply an excess of rajas or tamas, and the record does not assert it: the chapters that actually describe mental disease give a dosha-mediated pathogenesis, with the aggravated bodily doshas reaching the heart and obstructing the channels through which the mind operates to produce unmada (Ni. 7.4-5), and with apasmara setting in when sattva is destroyed by rajas and tamas while the heart is overwhelmed by the doshas (Ci. 10, Kaviratna's aphorisms 2-3). How that sits with Su. 11.45, which defines mental disease in purely motivational terms, is carried in contested rather than resolved here. Charaka classifies mind into three kinds (shuddha or sattvika, rajasa, tamasa) at Sha. 4.36, names sixteen types across Sha. 4.37-39 and summarises them at Sha. 4.40 on an avowedly analogical scheme of deities, demons and animals; the predominance principle that makes such a classification workable is stated in the mula at Sha. 3.13. Disease is classified as threefold, nija (endogenous), agantu (exogenous) and manasa (mental), the last arising from failure to obtain what is desired or from contact with what is disliked (Su. 11.45), and one of the three classes of therapy, sattvavajaya, is defined as restraint of the mind from unwholesome objects (Su. 11.54). What that restraint looks like in the treatment chapter is wider and harsher than the modern reading of it as psychotherapy suggests: Chikitsa 9 prescribes consolation and the deliberate use of opposite emotions, and also binding, whipping, confinement and induced terror.","contested":[{"question":"Is sattva a guna, a dosha, or the mind itself?","positions":["Charaka counts only rajas and tamas as manasa doshas, so sattva is the mind's undisturbed nature and not a dosha","Charaka also uses sattva as a synonym for manas itself (shariram sattvasamjnam cha), and separately as a term for mental endurance or strength, so the word carries at least three senses in the same text","Modern triguna instruments treat all three as symmetrical measurable dimensions, which flattens a distinction the classical text is careful about","Added on revision: a fourth sense is now cited, sattva as one of the eight saras in Vimana 8 (classical[18]), where it is a graded measure of strength standing in a list otherwise made of bodily tissues. Whether this is the endurance sense or a fourth thing again is not stated in the passage."]},{"question":"Is mental constitution a fixed trait or a current state?","positions":["Classical position: manasika prakriti, like sharirika prakriti, is determined at conception and fixed","State position, implied by the finding that guna profiles differ systematically between people in acute psychiatric illness and controls: what the instruments measure may be current mental state, not constitution","No study separating these was found in the searches named in gatheringNotes, and no longitudinal guna measurement through illness and recovery was among the retrieved records","Added on revision: the texts themselves pull both ways. Sha. 3.13 says the kinds of sattva are all present in one person and that one is named only by preponderance, which is state-like; Ni. 7.4 names upaklishta-sattva, afflicted sattva, as a susceptibility, which treats a guna state as a modifiable risk factor rather than a fixed type."]},{"question":"What is sattvavajaya, operationally?","positions":["Literally as Charaka defines it: restraint of the mind from unwholesome objects, closer to deliberate abstention than to a therapy (Su. 11.54)","As modern Ayurvedic psychiatry practises it: an umbrella covering counselling, psychoeducation, yoga, pranayama, chanting and behavioural advice, which is far broader than the classical definition","As a near-equivalent of cognitive behavioural therapy, a comparison frequently asserted and, in the records retrieved here, never tested head to head. The assertion is now sourced to PMID 23858273, which makes it with no method, no data and no comparison.","Added on revision: in the trial literature the word does not pick out one intervention. It was delivered as asana, pranayama, chanting and counselling in PMID 26170589, as relaxation techniques in PMID 32398908 and as trance or clinical hypnosis in PMID 23049189. Three studies, three interventions.","Added on revision: Charaka's own non-drug repertoire for unmada is wider and harsher than any of these. Ni. 7.8 lists vadha, bandhana, avarodhana, vitrasana, vismapana and vismarana, and Chikitsa 9 prescribes consolation with words of dharma and artha and the deliberate induction of an opposite emotion, and also whipping, goading, binding, solitary confinement and terrifying the patient with defanged snakes, tame lions and elephants, armed men, and officers threatening death on the king's order (classical[14], classical[15]). Any claim that sattvavajaya is the classical name for psychotherapy has to say what it is doing with these."]},{"question":"Does the manasa disease category require dosha involvement?","positions":["Charaka Su. 11.45 defines manasa roga purely by thwarted desire or imposed aversion, with no mention of dosha","Elsewhere the texts describe unmada and apasmara through dosha vitiation of the mind, implying manasa roga is dosha-mediated after all. This is now cited rather than referred to: Ni. 7.4 (classical[13]) and Ci. 10 (classical[16]).","Revised. The gathering pass said a reconciling reading that distinguishes the cause (motivational) from the pathogenesis (dosha-mediated) is 'a modern harmonisation' because 'the texts do not state this'. That overstated the case and has been corrected: Ni. 7.4 puts both halves in a single sentence, naming kama, krodha, lobha, harsha, bhaya, shoka, chinta and udvega among the susceptibilities AND the aggravated doshas obstructing the manovaha srotas as the mechanism, and Ci. 10's pathogenesis sentence is explicitly joint. What remains genuinely modern is the tidy two-level cause/pathogenesis schema; the raw material for it is in the texts.","The tension with Su. 11.45 is not thereby dissolved. Su. 11.45 is a definition of a disease class and mentions no dosha; Ni. 7.4 and Ci. 10 are accounts of two particular diseases. Whether the class is defined dosha-free while its members are all dosha-mediated is not something the texts retrieved here address."]},{"question":"Do the sixteen sattva types have any modern referent?","positions":["Some authors map them onto personality typologies or temperament dimensions","Others treat them as culturally specific analogies with no translatable content, noting they classify by resemblance to gods, demons, birds, snakes, fish and trees","No instrument among those retrieved here measures them, so in practice the modern literature retrieved here has abandoned them while continuing to cite the chapter they come from","Added on revision: the text's own wording supports the second position more than the first. Sha. 4.37-39 introduce each type with vidyat, 'one should know (a man of such traits) as X', and Sha. 4.40 gathers them sattvanukarena, after the manner of the mind of, so resemblance is the stated criterion and not an interpretation imposed on it."]},{"question":"Is the graded sattva of Vimana 8 the same construct as the triguna of Sharira 4?","positions":["New question added on revision, raised by the material the critic asked for. Sharira 4 gives kinds of mind, named by analogy and assigned by predominance. Vimana 8 gives sattva as the eighth sara, a quantity of mental strength measured for the assessment of bala, in a list whose other seven members are skin, blood, flesh, fat, bone, marrow and shukra.","A reading that makes them one construct has to explain why one is typed and the other graded, and why sattva appears in Vimana 8 among tissues.","A reading that makes them two has to explain the single word.","The texts retrieved here do not address the relation, and neither does any paper retrieved here. The modern instruments measure a graded quantity, which is formally the Vimana 8 shape, while citing the Sharira 4 chapter."]}],"notKnown":["Whether guna scores are stable within a person over time, or whether they track current mood and symptom state. No longitudinal study was found in the searches named in gatheringNotes.","Whether triguna assessment adds predictive or explanatory information beyond established personality and wellbeing psychometrics. No incremental-validity study was among the retrieved records.","Why the different triguna instruments (VPI, Mysore Triguna Scale, MHAS-TG) yield different factor structures, and which if any should be preferred.","Whether sattvavajaya has any effect beyond attention, expectancy and the yoga practices it is usually bundled with. None of the three retrieved trials isolates it, and the three do not deliver the same intervention, so there is at present no single thing to isolate.","Whether the OCD exception in the guna-diagnosis findings (patients not differing from controls on sattva) reflects something real about OCD or is a small-sample artefact.","What the relation is between manasika prakriti and sharirika prakriti. The texts assert both; no retrieved study measures their association.","Whether the sixteen sattva types can be measured at all, and whether anyone has tried. No instrument among those retrieved here attempts it.","Whether rajas and tamas behave like doshas in any testable sense, for example showing increase and decrease with identified causes and responding to opposite-quality interventions. Ni. 7.4 and Ci. 10 give the doctrine a mechanism (obstruction of the manovaha srotas, destruction of sattva by rajas and tamas) which is in principle the sort of claim that could be operationalised; nothing retrieved here operationalises it.","Whether the classical claim that mental disease requires non-drug therapy (knowledge, fortitude, memory, withdrawal) has ever been tested against pharmacotherapy in a comparative trial. No such trial was among the retrieved records.","Whether guna-based screening identifies people missed by standard mental health screening, or simply re-identifies the same people.","ADDED ON REVISION. Whether sattvavajaya scoping or systematic reviews exist in AYU or JAIM, as the critic's missing finding states. The two PubMed searches named in gatheringNotes returned eleven unique records and no review of that kind. Those journals are not fully indexed in PubMed, so this is not evidence that no such review exists; it is a record that the searches run here did not find one, and that no such reference could therefore be cited under this project's no-quote-no-citation rule.","ADDED ON REVISION. Whether controlled trials of sattvavajaya in anxiety and in depression exist, as the critic's overclaimed finding states. None in anxiety was found in those searches; the only depression record found was a single case report (PMID 41016220). The same indexing caveat applies.","ADDED ON REVISION. The standard-edition (Trikamji) verse numbers for three of the passages quoted here are not established: Chikitsa 9 (classical[15]), Chikitsa 10 (classical[16]) and Vimana 8 (classical[18]). Kaviratna's own aphorism numbers are given instead. For Vimana 8 the discrepancy is specific and unexplained: the critic addresses sattva sara to 8.110 and Kaviratna prints 123 at that paragraph, so the one-behind offset established elsewhere in this project for Vimanasthana 8 does not hold at this point in the chapter.","ADDED ON REVISION. Whether Kaviratna's 'subjecting them to control' at Sharira 1.21 renders svasya nigrahah, the mind's restraint of itself, or the restraint of the senses. The Sanskrit reads naturally as the former and his English as the latter, and the record does not resolve it. Because it is unresolved, this record does not use Sha. 1.21 as the textual root of sattvavajaya.","ADDED ON REVISION. The swastha definition (prasannatmendriyamanah, a person of pleasant atman, indriyas and manas), which the gathering-pass summary leaned on, is commonly cited to Sushruta Sutrasthana 15 and is not held in this record. No Sushruta citation was retrieved, so the sentence that rested on it has been removed from the summary and no claim here depends on it.","ADDED ON REVISION. Charaka Nidana 8 (apasmara nidana) and the remainder of Chikitsa 9 and Chikitsa 10 beyond the passages quoted are not covered. Only the definition and pathogenesis sentences are cited, because those are what bear on this concept's claims; the therapeutic detail of the apasmara chapters is outside the scope this record keeps.","ADDED ON REVISION.

Precisely what is and is not attested, since the gathered record flattened this: Charaka Nidana Sthana 1 lists the five items and defines each, and those lines are quotable in a public-domain English translation, Kaviratna's, which does contain the Nidana Sthana (classical[0] to classical[3]; the contrary finding is declined in stillOpen[0] with the evidence). What is NOT in Charaka is the group as a named or counted unit. The naming is commentarial, in Chakrapani's hetvadi-pancaka, and the five-fold formulation as a verse with a chapter titled for it is Madhava Nidana's. 'Well-attested textual construct', the gathered record's phrase, has been dropped: what is well attested is the five items; the pentad is a construct with a datable history, and the record now gives the three steps of that history with an address for each. The record also no longer claims the frame organises the modern BAMS curriculum, which was asserted with no citation anywhere in the record and is now in notKnown. What does not exist, so far as a bounded search can say, is evidence that applying the frame yields reproducible conclusions. No study was found measuring whether two physicians given the same patient agree on the nidana, the purvarupa, the rupa set, the result of an upashaya trial, or the samprapti. The nearest empirical evidence is negative: a 2024 case-vignette survey of 141 practitioners found substantial disagreement on diagnosis and on the samprapti of identical cases, and a 2019 nested reliability study found chance-corrected agreement between 0 and 0.4 on constitutional components that feed the frame, even though the same experts reached 95 per cent raw agreement on a consensus final label; a 2021 prakriti study adds ICCs of 0.72, 0.58 and 0.44. No diagnostic accuracy study was found, no prospective cohort in which purvarupa predicted later disease, and no controlled test of upashaya against any reference standard; the one paper found on purvarupa's predictive use calls for such work rather than reporting it. On PubMed on 2026-10-06 the phrase search \"nidana panchaka\" returned three records: the two Bulletin of the Indian Institute of History of Medicine philological notes that are modern[4] and modern[5], and PMID 41106206, a 2025 single-case report of Ayurvedic management of a vocal cord carcinoma, which is not cited in this record because an n-of-1 case report establishes nothing about the frame. 'upashaya' returned one record and 'anupashaya' none. Those counts are counts of those queries on that date, not a statement about the world's literature; the full query log is in gatheringNotes.","summary":"Nidana-panchaka is the name modern Ayurvedic teaching gives to a group of five things a physician is told to establish about a disease: its cause, its premonitory signs, its manifest signs, its response to a trial of contrary medicine, diet or regimen, and its pathogenic sequence. Charaka's Nidana Sthana 1 lists those five in a single prose line as what a disease is apprehended from, and defines each in the lines that follow; it does not group them under a name or call them five. The grouping as a named pentad appears in commentary, in Chakrapani's hetvadi-pancaka, and the five-fold formulation as a verse is Madhava Nidana's, whose first chapter is titled Pancha-nidana-lakshanam and is built around it. As a working device it structures a clinical history towards a disease name plus a dosha-and-tissue account of how the disease came about. It is not a test with an accuracy figure; the classical texts quoted here give no procedure for resolving disagreement between two physicians who apply it to the same patient; and the record found no study measuring whether two physicians applying it to the same patient reach the same conclusion. Contemporary sources describe it as the standard diagnostic reasoning template and samprapti as the element that individualises treatment; this record reports those as claims made, not as findings, and the one empirical test it found (PMID 39183608) ran against the second of them.","contested":[{"question":"Is the five-limbed set canonical, or a later editorial convention?","positions":["The five items are stated as a group in Charaka Nidana Sthana 1/6 itself, in one prose line, and each is defined in 1/7 to 1/12, so the material of the frame is samhita-period (classical[0] to classical[3]).","The group as a NAMED unit is not in Charaka. The earliest naming this record can address is Chakrapani's Ayurvedadipika on Vimana 1/2, 'jnata-hetvadi-pancakasya', eleventh century (classical[5]); the five-fold formulation as a verse, with a chapter titled Pancha-nidana-lakshanam, is Madhava Nidana 1/4, 'roganam pancadha smrtam' (classical[8]), and that is the text modern teaching inherits it from. On this reading the items are early and the pentad is a later organising convention.","Not settled by this search, and the two positions above are compatible: nothing found dates the practice of treating the five together, as opposed to the act of naming them so. The record takes no view on which reading is correct and the summary has been written to assert only what the three addresses support."]},{"question":"Is rupa the third limb, or is it linga?","positions":["Charaka's own wording at Ni. 1/9 is 'linga', with rupa listed as one of seven words of the same import (classical[0]).","Madhava Nidana and modern teaching use 'rupa', which is why the mnemonic reads nidana-purvarupa-rupa-upashaya-samprapti; the Madhava Nidana verse 4 line as retrieved reads purvarupani / rupani (classical[8]). The substitution is terminological rather than doctrinal, but it means quotations attributed to 'the fivefold rupa' may not match the Charaka text."]},{"question":"Does samprapti individualise treatment in actual practice?","positions":["Standard Ayurvedic pedagogy holds that samprapti-vighatana, breaking the pathogenic sequence, is what makes each prescription patient-specific. The record carries this as a position held, and has not found a citable primary statement of it in the classical sources quoted here; Charaka's Ni. 1/12 gives samprapti analytic headings and says nothing about individualising a prescription.","The 2024 case-scenario survey (modern[0]) found that stated theoretical constructs including samprapti did not uniformly determine prescriptions, and that practitioners disagreed with each other about the samprapti of the same case; the authors raise the possibility that the framework is weak rather than merely variably applied."]},{"question":"Is upashaya a diagnostic instrument or an early therapeutic trial?","positions":["Chakrapani, and Kaviratna following him, treat it as a means of ascertaining the disease that should not be mistaken for treatment. In Kaviratna this is explicitly a translator's footnote, marked '-T.', not a rendering of the verse (classical[1], translatorVoice).","Operationally it is indistinguishable from an n-of-1 therapeutic trial. Charaka's definition at Ni. 1/10 specifies the objects (medicine, diet, regimen) and the two modes (contrary, or contrary in effect) but no duration, no dose, and no rule for reading a partial response, which makes the distinction hard to sustain."]},{"question":"Is samprapti subdivided into five headings or six?","positions":["Five. The Sanskrit of Ni. 1/12 compounds strength and time into one member, 'sankhya-pradhanya-vidhi-vikalpa-balakala-visesair bhidyate', the definitional run that follows defines five, the fifth being 'balakalavisesah', and Charaka's Vimana 1/3 uses the same compound, '...vikalpabalakalavisesan' (classical[3], and GRETIL's Car_3,1.3 quoted at classical[5]'s source).","Six. Kaviratna's English reads 'number (or enumeration), predominance, kind (or order), solution of doubt, strength (or intensity), and Time', six items, and much modern writing follows that count."]},{"question":"What is the relation between nidana-panchaka and Sushruta's shatkriyakala?","positions":["They touch at two points that can be shown from text: Sushruta's fourth treatment-occasion is the appearance of purvarupa (Su.Su. 21/33) and his fifth is full manifestation (21/34), which is Charaka's rupa. To that extent the frames describe the same disease in the same order.","They are not reducible to each other. Sushruta's first three stages, sanchaya, prakopa and prasara, and his sixth, bheda, have no counterpart among the five limbs; the five limbs' nidana and upashaya have no counterpart among the six occasions; and the two lists do different work, one enumerating what to establish about a disease and the other when to intervene in it.","Whether either is a staging of the other, or whether samprapti simply narrates the six occasions, was not settled here. The common teaching claim that samprapti and shatkriyakala are the same content differently cut is a claim this record has not found a classical statement of, and has not tested."]}],"notKnown":["No published study was found reporting inter-rater agreement on any individual limb of nidana-panchaka taken separately.","Whether purvarupa lists have any predictive value: no prospective cohort was found in which listed prodromes were recorded and later disease incidence measured. The nearest item found, modern[7], proposes that the prameha purvarupa be explored as a basis for identifying pre-diabetes and calls the work urgent, which is a statement that it has not been done.","Whether upashaya-based reasoning improves outcomes compared with diagnosis without it; no trial was found that randomised on this. The term is also almost absent from the indexed literature: on 2026-10-06 a PubMed search for 'upashaya' returned one record, the Madhava Nidana philological note at modern[5], and 'anupashaya' returned none.","How disagreement between limbs is to be resolved when, for example, the rupa point to one disease and the upashaya response to another; the classical passages quoted here give no decision rule and no modern source supplying one was found.","What counts as a complete samprapti statement; no agreed minimum data set was found, so two samprapti accounts of the same patient cannot be systematically compared.","Whether the frame performs differently across conditions; the reliability data found come from knee osteoarthritis, from psychiatric inpatients and from healthy volunteers.","Whether any of the five limbs maps onto a measurable biological quantity; no biomarker proposed and validated for any of them was found.","ADDED on revision. The commentators' six-fold and eighteen-fold analyses of upashaya, which the critic asked for, are not in this record. Charaka's own Ni. 1/10 supports three objects by two modes, and that is now in the record as classical[1]. The arithmetic that yields six (hetu-viparita, vyadhi-viparita, hetu-vyadhi-viparita and the three corresponding viparitarthakari forms) and then eighteen (those six across medicine, diet and regimen) is attributed in modern teaching to the Madhukosha. It is excluded because it could not be sourced to a quotable text: no public-domain English Madhukosha exists, and the 1920 Sanskrit scan used at classical[8] has a Devanagari OCR text layer too damaged to quote a commentary passage from with confidence. The gap is stated rather than filled with a paraphrase.","ADDED on revision. Whether the frame organises the modern BAMS curriculum. The gathered record asserted this in both summary and evidenceState and cited nothing for it anywhere. No CCIM or NCISM syllabus document was retrieved and the claim has been removed rather than left standing on nothing. Likewise, that contemporary teaching presents the frame as the standard diagnostic reasoning template is reported in summary as a claim made about teaching, and no syllabus, textbook or curriculum document is cited for it in this record.","ADDED on revision. Whether Madhava Nidana applies the five-fold frame disease by disease through the rest of the work. The gathered record asserted this. Only chapter 1, its title and its verse 4, has been verified here (classical[8]); the rest of the 1920 scan was not read for this purpose and no translation of it is lawfully quotable.","ADDED on revision. Whether the compound nidana-panchaka itself occurs in any samhita. It was not found in the Charaka Nidana Sthana 1 and Vimana 1 and 4 passages or the Sushruta Sutrasthana 21 and 35 passages read here, and a commentarial pancaka and a Madhava chapter title were found instead. The search was bounded to those passages and to the two public-domain English translations plus GRETIL's partial Sanskrit Charaka; it cannot support a claim that the compound occurs nowhere.","ADDED on revision. Whether the three means of knowing at Vi. 4/3, aptopadesha, pratyaksha and anumana, stand in any stated relation to the five limbs. Both lists are in Charaka (classical[0], classical[6]). No passage was found in which the five are said to be reached by means of the three, so the common framing that the three are the epistemology the five sit inside is not asserted by this record.","ADDED on revision. Whether the literature is thin or the search was thin, for the areas the queries did not reach. The queries run are logged in gatheringNotes; no hand-searching of Ayurvedic journals outside PubMed, no AYUSH Research Portal or DHARA search, and no Indian-language literature search was done, and three of those are known to index Ayurvedic clinical work that PubMed does not."],"components":[{"term":"Nidana (hetu)","gloss":"The cause or causes.

That is three objects by two modes in the text itself. Its opposite, anupashaya, is aggravation on trial.

Within what this record retrieved there is no assay for ojas, no reference range, no validated clinical instrument, and no study in which anything called ojas was measured before and after an intervention. A PubMed query for ojas in title or abstract restricted to clinical trial or randomised controlled trial publication types returned nothing on 2026-10-06, which is the search that licenses that sentence.\n\nOn biochemical identification the record previously said that two proposals exist. That was a census a bounded search cannot support, and it was also wrong. Three are now retrieved: steroids and steroid classes in 1995 (PMID 7705867), kapha read as the degree of gene expression and \"correlated with the ojas of the body or total body defence mechanism\" in 2000 (PMID 11272402), and cholesterol with HDL-C as surrogate for healthy apara ojas in 2025 (PMID 41289791). All three are hypothesis or review papers whose authors say so, and none has been followed by a validation study in what was retrieved here. The searches run were: ojas in title; ojas in title or abstract with biomarker, biochemical or immunity; ojas with ayurveda; ojas with immunoglobulin, glycoprotein, albumin or albumen; ojas with thermodynamic, entropy or agni; and author searches on Hankey and on Patwardhan. The critic expected a Hankey thermodynamic account of agni and ojas and Patwardhan immunity-concept papers to turn up; the Hankey author query with ojas or agni in title or abstract returned nothing, and the Patwardhan immunity results retrieved are botanical immunomodulation studies rather than identifications of ojas. An immunoglobulin or glycoprotein reading was searched for by name and not retrieved. That is a statement about these searches and not about the world; a different search, and in particular one outside PubMed and into Ayurvedic journals that PubMed does not index, could find more.\n\nBhishagratna's \"albumen\" is deliberately not counted among those proposals. It is a translator's gloss carried silently through his whole rendering of Sushruta Sutrasthana 15, and his own footnote says the term is used \"primarily\" for protoplasmic matter in cells and \"secondarily\" for albumen. Counting it as a biochemical identification would be absorbing the translator's voice as doctrine, which this project has had to correct three times already. It is recorded as a position in contested, attributed to the translator.\n\nBeyond the proposals, the indexed literature retrieved here consists largely of narrative reviews that restate the classical doctrine in immunological vocabulary and stop. The quantitatively strongest item located, the Chyawanprash prophylaxis meta-analysis (PMID 39544586), is null on every efficacy endpoint with severe heterogeneity, and tests a formulation rather than the construct. The post-2020 Ayurvedic COVID literature was searched as the critic asked, and it changes the shape of the gap rather than closing it. Immune parameters were measured: a randomised placebo-controlled pilot trial quantified IL-6, TNF-alpha and hs-CRP (PMID 33596494), and a multicentric randomised AYUSH-64 trial reported faster clinical recovery (PMID 36928877) while a second AYUSH-64 randomised trial reported no difference in RT-PCR conversion (PMID 34908795). In none of them was ojas the exposure, an outcome, or measured at all. So the honest statement is not that nobody has measured immunity under an ojas-framed intervention, it is that nobody has measured ojas alongside the immunity, which leaves the identification exactly where it was. One retrieved paper does operationalise a mode of ojas derangement: a prospective DMD cohort scored ojovisramsa as a staging variable and found it differed significantly between ambulation stages (PMID 42161239), with no reliability data.\n\nCompounding all of this, the classical sources do not agree on what ojas is. Charaka's Sutrasthana 17 calls it a slightly yellowish pure blood in the heart at the aphorism Kaviratna prints as 74 and identifies it with normal phlegm at 114, while Sushruta calls it the quintessence of all seven dhatus and Bhishagratna's own footnote records authorities who deny that ojas and vitality are identical at all. Kaviratna's footnote to the anjali list in Sharirasthana 7 adds a fourth layer: a variant reading that makes ojas a kind of phlegm, which Gangadhara's commentary adopted and which Kaviratna rejects by declaring, in his own voice, that ojas is \"the blood of blood\". A construct whose primary sources define it several incompatible ways cannot be operationalised until that is resolved, and no modern paper retrieved here resolves it.\n\nOne thing the record previously got wrong in the other direction is worth stating plainly. It reported that the half-anjali quantity of ojas could not be found in either public-domain translation. It is there, in Charaka Sharirasthana 7, and it is now quoted. What is still unlocated is the para/apara vocabulary and the eight-drop figure. So the quantities are not all commentarial; one of them is scriptural and the division they are usually hung on may not be.\n\nThe correct overall statement is that ojas is a rich and internally detailed classical account of vitality and resistance, that its identification with immunity is an interpretive overlay rather than a finding, and that no operational definition of it has been validated in anything this record retrieved.","summary":"Ojas is described in the classical texts as the refined essence distilled from all seven bodily tissues, seated principally in the heart, pervading the body, and responsible for strength (bala), steadiness of the sense organs, complexion, voice and the capacity to withstand disease (vyadhikshamatva). Its depletion is said to produce fearfulness, weakness, emaciation, loss of lustre and, at the extreme, death. Three modes of derangement are distinguished: displacement from its seat (visramsa), corruption by vitiated humours (vyapat) and wasting (kshaya), and Sushruta supplies a sign list and a prognosis for each. The concept is the usual point of contact between Ayurveda and modern immunology, but the correspondence is an interpretive one: ojas as described covers reproduction, morphogenesis, mood and vitality as well as resistance to illness, and the classical sources do not agree among themselves on what ojas actually is. In Kaviratna's wording Charaka calls it, in one aphorism of Sutrasthana 17, a quantity of pure blood \"which is slightly yellowish\" residing in the heart, and forty aphorisms later identifies it with normal phlegm, while Sushruta calls it the quintessence of all the dhatus. The reddish-yellow description that circulates widely is Vagbhata's and is recorded here under Vagbhata, not under Charaka. This record makes no claim about how much modern evidence exists for or against the identification with immunity; it states what the searches named in gatheringNotes returned.","contested":[{"question":"What is ojas, materially?","positions":["Sushruta Sutrasthana 15: the quintessence of all seven dhatus from rasa to shukra, identical with vital power.","Charaka Sutrasthana 17, at the aphorism Kaviratna prints as 74: a quantity of pure, slightly yellowish blood residing in the heart.","Charaka Sutrasthana 17, at the aphorism Kaviratna prints as 114: normal phlegm (kapha) itself. Three aphorisms earlier the same chapter says \"The phlegm that is normal is called strength of the body\", which is how this identification reaches bala.","A fourth position recorded in Bhishagratna's note to Sutrasthana 14: certain authorities hold ojas to be the eighth and culminating dhatu, produced from the thin fraction of shukra.","A fifth, recorded in Bhishagratna's footnote to Sutrasthana 15: 'Several authorities hold a contrary view stating that Ojas (albumen) forms only one of the essentials of vitality and that the two are by no means identical.'","A sixth, and it is the translator rather than the text: Bhishagratna renders ojas throughout as \"albumen\", and his footnote to Sutrasthana 15 says the term means \"primarily ... protoplasmic matter as found in cells (Vindus)\" and \"secondarily ... albumen\". This is a nineteenth-century biochemical reading embedded in the translation itself. It is listed here as a position held by the translator, and it is excluded from any count of proposals in the indexed modern literature for that reason.","A seventh, textual rather than doctrinal: Kaviratna's footnote to the anjali list in Sharirasthana 7 reports a variant reading of the ojas line which Gangadhara read as \"the particular kind of phlegm known as ojas\", so the kapha identification has manuscript support outside Sutrasthana 17. Kaviratna rejects it and asserts in his own voice that ojas is \"the blood of blood, the most vital dhatu in the body\", which is the translator settling a question the text leaves open."]},{"question":"Is there a para/apara division, and what are the quantities?","positions":["The standard modern teaching distinguishes para ojas (a very small fixed quantity in the heart, commonly given as eight drops) from apara ojas (a larger circulating quantity, commonly given as half an anjali), and the 2025 biomarker paper builds directly on this division.","On the quantities the record's earlier negative result was half wrong and is corrected here. The half-anjali measure IS in the retrieved public-domain Kaviratna, in Charaka Sharirasthana 7, where the anjali list gives marrow one anjali, brain half an anjali, and semen and ojas \"the same (as above)\". So that figure is scriptural. Charaka introduces the list as known by inference rather than direct perception, and Kaviratna's footnote to the ojas line records a variant reading at exactly that point, so it is a disputed line even within the edition that carries it.","The eight-drop figure was searched for again on 2026-10-06 in both full texts and not located. Neither was the para or apara vocabulary as applied to ojas: the only Para and Apara in Kaviratna are the Nyaya categories Paratwa and Aparatwa in Sutrasthana 25, which are about priority and inferiority of place, season and age, not about two kinds of ojas.","So the honest position is that one of the two quantities is scriptural, the other is not located, and the two-kinds division that organises them is not attested in either translation searched. Whether the division is commentarial, or later, or simply a modern teaching convenience, this record does not establish."]},{"question":"What is the modern correlate of ojas, if any?","positions":["Steroids and steroid classes (Walton and Pugh 1995, PMID 7705867).","Kapha read as the degree of gene expression as protein synthesis, \"correlated with the ojas of the body or total body defence mechanism\" (Mishra and colleagues 2000, PMID 11272402).","Cholesterol and its products, with HDL-C as surrogate for healthy apara ojas (Sumantran and Nair 2025, PMID 41289791).","General immune competence, immunoglobulins or innate immunity, the commonest framing in clinical and popular Ayurvedic writing. A search for an immunoglobulin or glycoprotein identification by name retrieved none, so the framing is widespread in practice and not argued for in what was retrieved from the indexed literature.","That there is no single correlate, because ojas as described spans reproduction, foetal morphogenesis, mood, strength and resistance, and no one molecule does all of that."]},{"question":"Is ojas equivalent to immunity at all?","positions":["The equivalence is assumed in most clinical writing and in public health messaging, and vyadhikshamatva is routinely translated as 'immunity'. PMID 26195903 is a clean specimen: its authors gloss ojas as \"immune strength\" in the conclusion of a trial that measured blood sugar.","Against this: the classical functions of ojas include conception, foetal development, complexion, voice, sensory and intellectual function and courage, most of which have no immunological content, while the immune system's central features (specificity, memory, self and non-self discrimination) have no classical counterpart under ojas.","A separate point, raised by the Charaka Sutrasthana 28 passage added: the clearest classical statement about differential resistance to disease does not mention ojas at all. It makes resistance a function of the adequacy of flesh, blood and bone, of strength, and of the measure of food. If that is where the corpus locates vyadhikshamatva, then ojas and vyadhikshamatva are related but not identical even inside the classical frame, and the modern habit of treating the two terms as one may be importing a unity the texts do not assert."]},{"question":"Is ojo-kshaya at its extreme truly incurable?","positions":["Sushruta states it directly, and the sentence before it states the converse: visramsa and vyapat are to be treated by \"elixirs and remedies possessed of rejuvenating properties\", while a patient who has lost consciousness from excessive ojas waste is to be given up by the physician. Both sentences are now quoted in full.","This has never been tested in anything retrieved here, and as a prognostic claim it is unfalsifiable as stated, since the diagnosis of terminal ojo-kshaya is itself made from the moribund state it is meant to predict."]}],"notKnown":["No assay for ojas was located, so none of the three published proposals for a molecular correlate (PMIDs 7705867, 11272402, 41289791) can be checked against the thing it claims to mark.","No reference range or normal value is defined for any candidate ojas marker in an ojas frame.","Ojo-visramsa, ojo-vyapat and ojo-kshaya have sign lists in Sushruta Sutrasthana 15, now quoted, but no case definition another team could apply, and no interrater reliability data was located. The flat statement in the previous version of this record, that they have no operational criteria and no reported prevalence in any population, was too strong: PMID 42161239 scored ojovisramsa in a 67-participant DMD cohort and reported it differing significantly between ambulation stages. What remains unknown is whether that scoring is reproducible, whether it transfers outside a rare neuromuscular disease, and what prevalence any of the three modes has in a general population.","No study has shown that any intervention changes a putative ojas marker in parallel with a clinical outcome; the 1995 and 2025 proposals are both untested.","The para/apara distinction is not established from the public-domain translations. The half-anjali quantity IS, for ojas without qualification, at Charaka Sharirasthana 7, which corrects this record's earlier negative result. The eight-drop quantity was searched for again and not located, and neither was any para or apara vocabulary applied to ojas. Whether the division itself is commentarial, later, or a modern teaching convenience is not resolved by any source retrieved here.","Whether the three incompatible classical definitions describe one thing, three things, or a term that shifted meaning across recensions is not resolved by any source I found.","The claim that ojas passes between mother and foetus in the eighth month has no identified referent and has never been investigated.","What the clinician is actually judging when assessing ojas at the bedside - and whether two clinicians judge it the same way - has not been measured.","Whether Ashtanga Hridaya Sutrasthana 11 is a parallel locus for the three derangement modes, and at which verses, is not established. There is no public-domain English translation of the Ashtanga Hridaya, no Sanskrit text of it was retrieved, and the verse range 37-40 that circulates in secondary sources is unverified. The sign lists this record carries are sourced to Sushruta Sutrasthana 15, which was retrieved and quoted, so nothing in the record now depends on the Vagbhata locus; whether Vagbhata says the same thing is simply not covered here.","Whether the aphorism numbers Kaviratna prints for the passages used here (Sutrasthana 11 at 31, Sutrasthana 17 at 74 and 114, Sutrasthana 28 at 13, Sutrasthana 30 at 6-10, Sharirasthana 4 at 31) correspond to the standard Trikamji numbers is not established. The off-by-one offset documented for this translation was established for Chikitsasthana 15 and Vimanasthana 5 and 8, and has not been checked for these chapters, so no standard-edition number is asserted for any of them.","Why Kaviratna's printed aphorism number for the eighth-month ojas passage (31) differs from the number the Sanskrit source used in this record gives for what appears to be the same passage (Sharirasthana 4.24) is not resolved. The two numbering systems have not been reconciled.","No study was located in which ojas was measured alongside an immune parameter. Immune parameters have been measured under Ayurvedic interventions (IL-6, TNF-alpha and hs-CRP in PMID 33596494), and clinical outcomes under AYUSH-64 (PMIDs 36928877, 34908795), but in none of the retrieved studies was ojas an exposure, an outcome, or measured. The question the previous version of this record asked, whether ojas status correlates with any measured immune parameter, therefore remains open because the studies that measure the second thing do not measure the first.","Whether the identification of ojas with vyadhikshamatva is supported by the corpus at all is not settled here. The clearest classical statement on differential disease resistance located in this gathering (Charaka Sutrasthana 28, quoted) makes no mention of ojas, and the record has not searched the corpus systematically for a passage that joins the two terms explicitly.","Whether the half-anjali measure is reproducible as a reading is not established.

The sequencing detail is specific enough to be checkable: three days of oily food after oleation before purgation and one before emesis (Ca.Su.13.80-81), seven days between a purgative and the oil enema and the oil enema before the decoction enema (Bhishagratna's Chikitsa XXXVII.2 and XXXVIII.1), a purgative dose set by the threefold koshtha (XXXIII.15), and a gruel count set by the measured volume expelled (XXXIX.3-4). It is not internally consistent, and this revision withdraws the claim that it is. Three inconsistencies sit inside the record's own sources. The membership of the five cannot be settled from them: the one passage in the retrieved material that enumerates a group of five names oleation, purgation, emesis, asthapana and anuvasana, which matches neither scheme the record previously contrasted, and it does so in the translator's gloss rather than in the text. Charaka Sutrasthana 16 counts increase of the digestive fire among the signs of a properly purified body while Sushruta's recovery chapter opens by saying the digestive fire grows dull after exactly these procedures, a tension Bhishagratna resolves in a footnote of his own. And Bhishagratna records Dallana reading the word 'panchakarma' in Sushruta Chikitsa 13 as something else entirely. On top of that, the two stated payoffs, durability and preparation for rasayana, are both argued by analogy: faults subdued by correctives cannot reappear (asserted), a purged body is a tank baled dry, an unprepared body is sapless wood, an uncleansed body is dirty cloth. The one passage that offers something closer to a mechanism, XXXIII.21-22, explains the two routes by whether the drug is digested, which is a claim about the drug and not about the dosha. The modern evidence does not test the central claims, on the evidence this record searched, and the searches are now named in gatheringNotes rather than left implicit. No systematic search was run and none is claimed. Within those searches: the strongest study, Peterson et al. 2016, is a real controlled metabolomic study with proper multiple-testing correction, but the intervention it tested was a six-day residential programme combining herbs, vegetarian diet, meditation, yoga and massage, so its finding of altered plasma phosphatidylcholines cannot be attributed to the eliminative procedures, and the paper makes no clinical outcome claim. The clinical trials that do isolate a procedure are small, unblinded, lack a no-procedure arm, and confound the procedure with a follow-on palliative drug. The most obvious modern mechanistic hypothesis, that these are gut-directed interventions acting through the microbiome, is described in a 2024 review as nascent with too few studies to support categorical conclusions. A 2026 registered protocol from an Ayurvedic university is still single-arm with surrogate endpoints, which is itself a fair index of where the field stands. On safety, this revision stops asserting that nothing was found. The search found one prospective single-centre pharmacovigilance survey that attributes 23 of 52 confirmed adverse drug reactions in a hospital year to panchakarma, with no per-procedure denominator, and one 15-patient before-and-after study of serum electrolytes after purgation. Neither gives an adverse-event rate. A 2008 JAMA assay of internet-sold Ayurvedic medicines, which found detectable lead, mercury or arsenic in a fifth of 193 products, is recorded as context for the safety of orally administered classical preparations and explicitly not as evidence about the drugs used in panchakarma, which it did not sample. The honest summary is that panchakarma is a well-documented and elaborately specified traditional procedure, specified down to the dose and the meal count, whose central claims of durability and preparation for rasayana have not been tested in anything this record located, whose one respectable piece of biochemical data does not bear on those claims, and whose own textual tradition does not agree on what the five procedures are.","summary":"Panchakarma is the name used for a set of five eliminative procedures that constitute internal shodhana, together with the preparatory and recovery phases that surround them. The stated rationale is sequential and mechanical: aggravated doshas that have lodged in the tissues must first be loosened and brought back to the gut by internal and external oleation (snehana) and heat (swedana), then expelled by the route appropriate to the dosha and its seat, then followed by a graded re-feeding regimen (samsarjana krama) while digestive capacity is weak. Each of those three steps is now cited to an operative passage: Sushruta's emesis-and-purgation chapter states the loosening step and makes it mandatory, distinguishes the upward from the downward route by the behaviour of the drug, and grades the dose to the bowel type; Sushruta's post-procedure chapter and Charaka's Sutrasthana 15 give the graded re-feeding. The claimed payoff is durability, since Charaka holds that faults subdued by correctives cannot reappear and Sushruta compares a purged body to a tank baled dry, and preparedness, since Sushruta holds that rejuvenative therapy given to an uncleansed body is like dyeing a dirty cloth. Both payoffs are argued by analogy rather than by a mechanism. What the five procedures are is not settled and this record does not settle it: the enumerations it can actually source do not agree with each other, and in Sushruta a commentator is recorded disputing the ordinary reading of the word. The record cites procedural passages for emesis, purgation, both enemas, nasal administration and the graded re-feeding. It cites none for bloodletting and quotes no Vagbhata at all; both limits are stated in notKnown rather than left silent.","contested":[{"question":"What are the five karmas?","positions":["Charaka's set is usually given as vamana, virechana, niruha (decoction) basti, anuvasana (oil) basti and shirovirechana/nasya, with the two enemas counted separately and bloodletting excluded. UNSOURCED IN THIS RECORD: the Charaka passage that enumerates them is in Siddhisthana, which is not in the Kaviratna volume this record reads, and Ca.Su.2.34-35 names 'the five acts' without listing them. The position is retained as the standard report, not as a sourced claim.","Sushruta and Vagbhata are usually said to count raktamokshana (bloodletting) among the five and to treat the enemas as one. UNSOURCED IN THIS RECORD: no passage in Bhishagratna Volume II that was read enumerates such a set, and no Vagbhata is quoted anywhere in this record. The gathering pass supported this position with a verse attribution for Ashtanga Hridaya Sutrasthana 14 taken from an unnamed chapter summary; that attribution has been removed as unverifiable. The position is retained as the standard report and is flagged so that nothing downstream treats it as cited.","A third enumeration is actually retrievable, and it matches neither. At Sushruta Sarira Sthana, Bhishagratna's chapter II, sections 5-12, the group named is oleation (sneha-karma), purgatives, emetics, asthapana and anuvasana, and in the next paragraph Bhishagratna glosses the Sanskrit 'oil etc., purgatives etc.' as '(Pancha-karma)', with a footnote supplying those members. Oleation is inside the five here and nasal administration is not. This is the translator reading the term, not Sushruta enumerating it, and it is recorded as such.","Bhishagratna's footnote to Sushruta Chikitsa 13, section 7 records that Dallana, the standard Sushruta commentator, glosses the term in that passage as something other than the five eliminative measures, taking it to mean the measures used against kushtha affecting bone as the fifth dhatu. The word was not univocal even in the commentarial period.","The consequence, which this record states rather than resolves: the referent of 'panchakarma' is not stable across the sources this record can quote, and a record that picked one would be choosing rather than reporting."]},{"question":"Do the preparatory steps have an independent rationale or are they part of the eliminative act?","positions":["The classical sequencing rules treat snehana and swedana as mandatory precursors with specified intervals (Ca.Su.13.80-81), and Sushruta states the mobilising function outright: oleation, heat and secretion-producing food so that the doshas 'would be loosened and dislodged from their seats' (Bhishagratna's Chikitsa XXXIII.3).","The reason Sushruta gives for the preparation being mandatory is an analogy, not a mechanism: a body given a purgative or emetic without prior oleation and heat 'breaks up like a piece of sapless wood at the time of bending it' (XXXIII.33). The same chapter also makes the preparation repeatable and conditional, requiring a second oleation and heat before purgation after an emesis (XXXIII.14) and a drying phase first in those habituated to oily food (XXXIII.29-30), which reads as an independently managed step rather than a formality.","No study located by the searches named in gatheringNotes separates the preparatory phase from the eliminative phase, so whether snehana and swedana contribute anything beyond the diet and rest they entail is untested here.","Bhishagratna's own note on Sushruta Chikitsa 32 warns that 'sveda' does not necessarily mean producing sweat, which undercuts readings of the step as a diaphoretic or detoxifying measure in the modern sense. The warning is the translator's, about his own English, and is used here only as that."]},{"question":"Does purification kindle the digestive fire or dull it?","positions":["Charaka Sutrasthana 16, at Kaviratna's aphorisms 14 to 16, lists 'the increase of the digestive fire' first among the signs of one whose system has been properly purified, and makes improved digestive capacity one of the blessings of proper purgation; Sushruta says the same at Bhishagratna's Chikitsa XXXIII.18.","Sushruta's recovery chapter opens by stating the reverse: 'The digestive fire (Kayagni) of a person naturally grows dull after the exhibition of emetics and purgatives, after the administration of a Niruha-Vasti, after the internal application of a Sneha and after blood-letting' (Bhishagratna's Chikitsa XXXIX.2). The whole graded diet is built on that premise.","Bhishagratna harmonises the two in a footnote at that point, saying the fire is ultimately kindled by these measures but immediately afterwards becomes dull and sluggish. ATTRIBUTION: that resolution is the translator's. Neither passage as retrieved says it. It is recorded here because it is a plausible reading and because this project has three times absorbed a translator's harmonisation as doctrine, so the attribution is the point.","What follows for the record: the two statements are both in the sources and the reconciliation is not, so the claim that the classical account is internally consistent has been withdrawn from evidenceState."]},{"question":"Is panchakarma a treatment, a preparatory measure, or a seasonal health practice?","positions":["Charaka Su.16 frames it as definitive treatment with durable effect, and Sushruta's benefits-of-purgation passage (Bhishagratna's Chikitsa XXXIII.18) does the same with a different analogy.","Sushruta Chikitsa 27.2 frames it as a precondition for rasayana to work, and Bhishagratna's Chikitsa XXXVII.2 frames the oil enema as requiring prior purification in the same way, so the preparatory framing is internal to the procedure set and not only a bridge to rasayana.","Contemporary practice and the 2026 protocol frame seasonal purification (ritu shodhana) in healthy people as a healthspan measure, a use for which the protocol itself concedes the evidence remains a gray area."]},{"question":"What does the Peterson 2016 metabolomic finding show?","positions":["It is widely cited as biochemical evidence that panchakarma produces measurable physiological change.","The intervention was a multi-component residential programme, so the same data are equally consistent with six days of vegetarian diet, meditation and rest producing the phosphatidylcholine shift with no contribution from the eliminative procedures. The paper does not claim otherwise."]},{"question":"What can be said about the safety of panchakarma?","positions":["The classical texts describe the harms of over-administration in clinical detail and make them the operator's responsibility: Charaka Su.16 (Kaviratna 7-9) describes graded over-purgation up to dark-blue blood and then tells the patient to seek a learned physician, and Sushruta states flatly that 'purgatives administered by ignorant physicians to persons who ought not to be purged (often) prove fatal' (Bhishagratna's Chikitsa XXXIII.19).","The modern safety literature the search named is thin but not empty. A prospective single-centre pharmacovigilance survey (PMID 27011712) attributes 23 of 52 confirmed hospital ADRs in one year to panchakarma, mostly mild to moderate and mostly gastrointestinal or cutaneous, with an overall ADR incidence of 1.14 percent in the hospital's patient population. A 15-patient study of serum electrolytes after purgation (PMID 24696575) found deviations within the normal range.","Neither of those is an adverse-event rate for the procedure. The pharmacovigilance denominator is the hospital population rather than the people who underwent a procedure; spontaneous reporting under-counts; and 23 of 52 is a share of reactions, not a risk. The record states this as an open gap rather than letting the two studies stand in for one.","A separate and distinct safety question is the composition of the preparations administered. A 2008 JAMA assay (PMID 18728265) found detectable lead, mercury or arsenic in 20.7 percent of 193 internet-purchased Ayurvedic medicines, with no difference by country of manufacture and no protection from a GMP claim. It sampled none of the drugs used in panchakarma, so it bears on the class of product and not on this procedure, and the gap it leaves is recorded in notKnown."]}],"notKnown":["Whether the eliminative procedures contribute anything beyond the diet, rest and practitioner contact that accompany them.

It therefore cannot be read as an adverse-event rate for panchakarma, and it does not tell this record anything about the contamination status of the specific drugs panchakarma uses. What it does establish is that contaminant content in Ayurvedic medicines on open sale was substantial and was not predicted by country of manufacture or by a GMP claim, which is the context any safety discussion of orally administered classical preparations has to sit in. The record carries a notKnown entry for the gap it leaves open. It also carries a published erratum (JAMA 2008 Oct 8;300(14):1652) and a published comment with author reply (JAMA 2009 Jan 21;301(3):271-2), neither of which was retrieved.","quote":null,"design":null,"n":null}],"openQuestions":[],"citationsChecked":"2026-10-08","source":"https://nighantu.ageayurveda.com/concept/panchakarma-rationale/","canary":"94f594b184708460"},{"slug":"prajnaparadha","page":"/concept/prajnaparadha/","title":"Prajnaparadha (error of judgement as a cause of disease)","domain":"etiology","domainGroup":"pathology","evidenceState":"WHAT THE CLASSICAL MATERIAL SUPPORTS. The classical claims in this record are quoted and located, in a public-domain English translation for the English and in the Sanskrit original for the Sanskrit. That establishes what Charaka's text says about prajnaparadha. It establishes nothing about whether what the text says is so.\n\nWHAT THE MODERN REFERENCES ARE AND ARE NOT. The earlier version of this paragraph opened by saying that the concept 'rests on classical exegesis alone', while the record's own reference list contained empirical studies. That sentence is withdrawn as self-contradictory. The accurate division is this. Three of the references are exegesis: DOI 10.21760/jaims.v3i4.13295, 10.47468/csne.2021.e01.s09.046 and 10.47070/ayushdhara.v13i1.2545, all non-indexed or non-empirical, all restating the Charaka verses in psychological or neurobiological vocabulary and asserting equivalences with health-risk behaviour, cognitive distortion, akrasia, executive dysfunction or reward pathways, none reporting data, participants or any measurement of prajnaparadha. Two further references are about prajnaparadha and are also not empirical: PMID 22557014, a narrative argument linking the concept to AIDS prevention, and PMID 11611678, a 1982 history-of-medicine paper whose text this record has not read. The remaining three references are genuine empirical work and none of them is about prajnaparadha: PMID 40774071 builds an instrument for triguna, PMID 24191170 and PMID 30653338 measure diagnostic agreement for pulse, tongue, prakriti and agni. They are carried here as comparators for neighbouring constructs, and labelled as such in their own quality fields. So the honest statement is narrower than the old one: no empirical study of prajnaparadha itself was found in the searches named below, and the empirical studies cited here are about other things.\n\nON RELIABILITY, A CORRECTION. The earlier paragraph asserted that there is 'no inter-rater reliability estimate'. That was wrong at field level and is withdrawn. Inter-rater reliability of Ayurvedic diagnosis has been estimated more than once, and the estimates are low. Kurande and colleagues report average pairwise weighted kappa of 0.07 for pulse, 0.17 for tongue and 0.28 for prakriti across all 105 pairs of fifteen doctors (PMID 24191170). Witt and colleagues report kappa between 0 and 0.4 for prakriti, agni and related constructs in knee osteoarthritis patients (PMID 30653338). What survives of the original point is this: neither study rated prajnaparadha, and no reliability estimate for prajnaparadha turned up in the searches named below.\n\nTHE SEARCHES THAT WERE ACTUALLY RUN, on 2026-10-06. PubMed esearch on 'prajnaparadha' returned one record, PMID 22557014, which is a narrative piece on achara rasayana and sadvritta in AIDS prevention and not a study of prajnaparadha. PubMed esearch on 'prajna-aparadha', 'prajnaaparadha' and 'prajna+aparadha' each returned one record, PMID 11611678, Krishan 1982, which is on the concept; so the earlier sentence that a PubMed search returns a single record about a different subject was wrong on the variant spellings and is corrected. PubMed esearch on 'pragyaparadha' returned nothing. Crossref resolved the three exegetical DOIs and confirmed their titles, journals and years. A web search for a validated prajnaparadha assessment instrument returned development and validation work for prakriti and for triguna, and returned no instrument for prajnaparadha. Kaviratna's Charaka was searched in full OCR for the term and for its English renderings.\n\nTHE NEGATIVES, SCOPED TO THOSE SEARCHES AND TO NOTHING WIDER. Within what was searched, the record found no operational definition of prajnaparadha, no instrument that measures it, no reliability estimate for it, no prospective cohort in which it is scored at baseline and outcomes are counted, and no trial in which an intervention targeting it is compared against a comparator. These are findings about a bounded search, not about the world. PubMed and Crossref do not index Indian MD and PhD dissertations, and CTRI, Shodhganga, the AYUSH Research Portal and DHARA were not searched for this record. The record therefore does not claim that no prajnaparadha scale or trial exists anywhere; it claims that it found none, and names where it did not look. The corresponding gaps are listed in notKnown rather than left implied here.\n\nTWO ADJACENT OBSERVATIONS WORTH KEEPING IN VIEW. First, the sub-class with the most obvious physiological reading, deliberate forcing or suppression of natural urges at Sharira 1/103, is in principle testable, and nothing found here tests it at the level the doctrine claims. Second, where Ayurvedic mental and constitutional constructs have been operationalised in the literature found here, it has been triguna and prakriti, and measured agreement for the better-developed of those was poor to fair. The record offers no estimate of how a construct as broad and as morally loaded as prajnaparadha would fare, and declines to predict that it would fare worse, because it has no basis for the prediction.\n\nSTATING IT PLAINLY. In the literature found here, prajnaparadha is an attribution, not a finding.","summary":"Prajnaparadha is the Ayurvedic category for disease caused by a failure of judgement rather than by an external agent or by the passage of time. Charaka defines it as the aggregate of harmful acts committed by a person whose dhi (comprehension), dhriti (restraint) and smriti (memory) have lapsed, and lists the acts concretely: forcing or suppressing natural urges, reckless exertion, sexual excess, acting against known self-interest, and conduct driven by envy, pride, fear, anger, greed, delusion and conceit. It is one of the three general causes of disease in Charaka's scheme, alongside unwholesome sensory contact and time, and Sutra 11/43 names the three together. The claim is causal and moral at once. Sharira 1/102 calls prajnaparadha sarvadosha-prakopana, which Kaviratna's own footnote reads as covering both the three bodily doshas and transgressions from duty generally, so how much physiology that compound carries is not settled by the word itself. Sutra 7/51 extends the category even to disease arising from poison, fire, weapons and assault, and in the epidemic chapter at Vimana 3/20 it is placed at the root of the chain that ends in vitiated air, water, land and season. The category also does clinical work in at least one place: at Nidana 7/10 prajnaparadha is given as the cause of exogenous insanity, expressly against the view that acts of a previous life are the cause. Unlike a diagnosis, it is not a named disorder; it is an attributed cause, and Sharira 1/109 locates it in the mind rather than in the body. Everything in this paragraph reports what the classical text asserts. The record makes no claim that any of it has been tested, and the evidence paragraph below states what has not.","contested":[{"question":"How wide is the category? Charaka gives two definitions that do not obviously coincide.","positions":["Sharira Sthana 1 defines it narrowly as the acts of a person whose dhi, dhriti and smriti are specifically impaired (Sharira 1/102, Kaviratna 109), which makes the impairment the diagnostic entry point.","Sutra Sthana 11 defines it as the mithyayoga of speech, mind and body, that is, any harmful voluntary exertion whatever (Kaviratna's Sutra 11, verse 41), which makes the category nearly unbounded.","Sutra 7/51 widens it again in a different direction, to disease arising from poison, fire, weapons and assault, which are not voluntary acts of the sufferer at all.","Commentators generally harmonise the first two by treating the second as the operational test and the first as the mechanism, but the texts themselves do not say this, and this record has not read a commentary in a quotable edition."]},{"question":"Is prajnaparadha genuinely independent of the other two general causes?","positions":["The classical position treats the three as a coordinate triad of distinct causes, stated as such at Sutra 11/43: asatmyendriyartha-samyoga, prajnaparadha and parinama, 'each subdivided into three kinds, constitute the causes of disease'.","Kaviratna, translating in 1896-1913, objected in his own footnote to Sharira 1.135 that the first and third causes 'are scarcely exclusive of each other' and that diseases under the second may be due to the same causes as the first and the third, concluding 'Altogether, the classification does not seem to be scientific'. This is a contemporaneous internal criticism from within the translation tradition, not a modern one, and it is the translator's voice rather than the text's.","Modern Ayurvedic authors generally treat prajnaparadha as the superordinate cause on the strength of Vimana 3, which makes the triad asymmetric rather than coordinate."]},{"question":"Is prajnaparadha a moral category, a cognitive one, or both?","positions":["The Vimana 3 chain runs through adharma and prior sinful acts, which reads as moral and karmic.","Sharira 1/109 (Kaviratna 116) locates it entirely in the mind, manaso gocaram hi tat, and Kaviratna's note to that verse excludes the physical element of the act, which reads as cognitive. The exclusion is his gloss, not the verse's words.","Nidana 7/10 sets prajnaparadha against the view that acts of a previous life cause exogenous insanity, which cuts the other way: here the text prefers a present cognitive fault over a karmic one.","Contemporary authors usually recast it as health-risk behaviour or lifestyle error, which drops both the karmic and the faculty-impairment content without acknowledging the substitution."]},{"question":"Does prajnaparadha make Ayurvedic etiology unfalsifiable? Added in answer to a critic finding.","positions":["The case that it does, assembled from this record's own quoted material: the enumeration of acts closes with 'These and such other acts' (Kaviratna Sharira 1.115), so no act is specified as falling outside the category; Sutra 11, verse 41 sweeps in 'everything, in brief, that is an injurious or harmful exertion of speech, mind and body, though omitted in the above enumeration'; Sutra 7/51 extends the category to disease from poison, fire, weapons and assault; and Vimana 3/20 extends it to vitiated air, water, land and season. On that reading there is no disease and no treatment failure that the category cannot absorb after the fact, and no observation that could count against an attribution.","Kaviratna reached a related verdict from inside the translation tradition, in his footnote to Sharira 1.135: the classification 'does not seem to be scientific'. His ground was overlap between the causes rather than unfalsifiability as such, so this supports the objection without being the same objection.","What would settle it in the other direction is an operational definition that specifies, in advance, what would NOT count as prajnaparadha. The record has not found one; see the evidence paragraph and notKnown.","A defence is available to the tradition, that the category is prescriptive and preventive rather than predictive, which would make falsifiability the wrong test. Sutra 7/53 is prescriptive in exactly that way. The record records this as an available reading and not as a sourced position, because it has not found it argued in print; the gap is listed in notKnown."]},{"question":"Does the category import blame onto the sick, and is it clinical or moral in use? Added in answer to a critic finding. This sharpens the moral-or-cognitive question above into a question about who is held at fault.","positions":["That it does locate fault in the sufferer: Sutra 7/51 assigns even diseases from poison, fire, weapons and assault to the patient's own prajna erring, prajna tesv aparadhyati. On the face of the verse, the victim of an assault is the party whose judgement is at fault.","That the fault is collective rather than personal: in Vimana 3 the agents are the foremost inhabitants of a country, city, town or village who 'transgressing righteousness, set the example of unrighteousness', and the sick are the population that suffers the consequence. Read that way the chapter is closer to a social-determinants argument than to patient blame.","That its use at Nidana 7/10 is clinical rather than moral: there it functions as the hetu that distinguishes agantuja unmada from the dosha-born varieties, which is diagnostic work, and it is preferred over the past-life-karma account. Whether substituting a present fault for a past-life fault lessens the blame or merely relocates it is not something the text addresses.","The record has not retrieved a source that argues the ethical question directly. The one indexed paper that engages the karma question by title is PMID 11611678, and its text was not retrieved, so nothing is attributed to it."]},{"question":"Is prajnaparadha one of three parallel causes, or the cause of the other two? Added in answer to a critic finding.","positions":["Parallel: Sutra 11/43 states the three as a coordinate triad, trayas trividha-vikalpa hetavo vikaranam, three causes each threefold, with no priority among them. Sharira 1/98 likewise lists the three together as the causes of duhkha.","Upstream: Sharira 1/102 calls prajnaparadha sarvadosha-prakopana; Sutra 7/51 makes it the fault behind agantu disease, which is the territory of the other causes; and Vimana 3/20 makes it the yoni, the source, of adharma and of prior acts, and so of vitiated season and element, which is the territory of kala.","A structural observation that can be read either way: Sharira 1 lists the three causes once at 1/98 and then explains only prajnaparadha at length, 1/99 to 1/109. That is either emphasis or subordination, and the chapter does not say which.","Kaviratna's footnote to Sharira 1.135 observes the same asymmetry from the translator's side, that the causes are not mutually exclusive, without resolving the architecture.","The texts gathered here do not state which architecture is intended, and this record does not choose."]}],"notKnown":["Whether prajnaparadha can be scored reliably by two independent trained examiners at all. No kappa for prajnaparadha was found in the searches named in evidenceState. Kappas have been published for other Ayurvedic constructs: 0.07, 0.17 and 0.28 for pulse, tongue and prakriti (PMID 24191170), and between 0 and 0.4 for prakriti, agni and related constructs (PMID 30653338).","Whether any measurable outcome follows from a prajnaparadha attribution that does not follow equally from ordinary behavioural risk-factor assessment.","Whether the specific classical claim that habitual suppression of natural urges causes the enumerated downstream disorders holds up in any controlled observation.","How prajnaparadha is to be distinguished in practice from the mithyahara-vihara (dietary and behavioural error) named in disease-specific nidana chapters, since the act lists overlap heavily.","Whether the dhi/dhriti/smriti triad corresponds to any separable cognitive functions, or whether it is one faculty described three ways. The only sourced statement this record has on the point is Kaviratna's footnote to Sharira 1.105, in his own voice: 'Dhi, Dhriti, and Smriti are explained by the Commentators as implying only different functions of the Understanding or buddhi.' That is the translator reporting the commentators collectively, with none of them named at that point, and the earlier version of this record stated flatly that 'Charaka's own commentators say the latter', which went further than the source allows.","Whether Chakrapani and Gangadhara in fact disagree over whether the dhi/dhriti/smriti triad is a psychological faculty model or a soteriological one. A critic finding asserts this is a live disagreement between them. The record could not verify it and does not assert it either way. What was checked: Kaviratna's public-domain Charaka, which names Gangadhara and Chakrapani frequently elsewhere but, at Sharira Sthana 1, reports the commentators only collectively and only on the faculty question. No public-domain English translation of the Ayurveda Dipika or of Gangadhara's Jalpakalpataru is available to quote, and the Sanskrit of neither commentary was retrieved for this record.","Whether the epidemic claim of Vimana 3, that collective moral failure precedes vitiation of air, water, land and season, is intended literally, allegorically, or as a social-determinants argument. The sources do not settle this. The Sanskrit of 3/20 does carry va, 'or', in tanmulam va'satkarma purvakrtam, which loosens the chain the English presents as fixed, but it does not settle the register.","What, if anything, distinguishes an act of prajnaparadha from an act simply done in ignorance, given that the definition requires impaired judgement rather than culpable knowledge.","Whether sarvadosha-prakopana at Sharira 1/102 means the three bodily doshas, transgressions from duty generally, or both. Kaviratna's footnote takes it both ways and then says Charaka 'has his eye, however, on wind, bile, and phlegm in particular'. That is a translator's judgement on an ambiguous compound and the record does not promote it to doctrine, so how much physiology the claim carries is open.","Whether Ashtanga Hridaya and Ashtanga Sangraha carry this doctrine, and in what form. The earlier version of this record asserted that both 'carry the same triad of general causes and the same dhi-dhriti-smriti definition in abbreviated form', with no chapter, no verse and no quote. That assertion is withdrawn and the citation removed; see citationsRemoved. Two things point against it as stated: Ashtanga Hridaya Sutrasthana 1 organises the causes of disease as the hina, mithya and ati yoga of kala, artha and karma, which is a different scheme from Charaka's named triad, and the prajnaparadha locus attributed to Vagbhata by wisdomlib is Ashtanga Hridaya Sutrasthana 4.33-34, in the chapter on prevention, which parallels Charaka's Sutra 7/53 rather than the Sharira 1 definition. Neither was verified against a Sanskrit edition for this record and no public-domain English translation of Vagbhata exists to quote, so this record now asserts nothing about Vagbhata. The locus to check first is Ashtanga Hridaya Sutrasthana 4.33-34.","Whether the unindexed Indian MD and PhD dissertation literature contains prajnaparadha assessment scales. A critic finding states that several theses develop them. The record cannot confirm or deny it: Shodhganga, the AYUSH Research Portal and DHARA were not searched for this record, and PubMed and Crossref do not index those theses. This gap is the main reason the negatives in evidenceState are scoped to named searches rather than stated absolutely.","Whether CTRI holds any registered trial with prajnaparadha as an eligibility criterion, an exposure or an outcome. CTRI was not searched for this record.","Whether the defence that prajnaparadha is a preventive and prescriptive frame rather than a predictive one has been argued anywhere in print, which is what would be needed to turn it from an available reading into a sourced position at contested question 4.","What Krishan 1982 (PMID 11611678) argues. It is the one indexed paper found whose subject is the concept itself, it carries no abstract in PubMed, and its full text was not retrieved.

Taking the eleven modern references in this record by design class: three are human randomised trials of classical polyherbal rasayana formulations, of which one tests a disease indication (iron deficiency anaemia) rather than the rejuvenative claim; three are systematic reviews or meta-analyses of randomised trials of single herbs (Bacopa monnieri, Withania somnifera twice); three are narrative reviews with no primary data; and two are preclinical, one in Drosophila and one in rats. The record previously presented a count of eight references without this breakdown, which overstated the coverage, and it described the tested set as 'chiefly Amalaki rasayana and Chyawanaprash', which was true of the references then gathered and not true of the literature. The single-herb rasayana dravyas do carry randomised human trials with validated cognitive endpoints, and the Withania meta-analysis pools twenty of them. That corrects the record's former position that no human work exists on the cognitive claims. It does not make the classical claim supported, for four reasons that the record now states rather than implies. The single-herb trials test standardised extracts over eight to twelve weeks, not classical formulations under a classical regimen, and none has a longevity endpoint on any relevant timescale. Whether those herbs are even the drugs the classical medhya list names depends on plant identifications that the commentarial tradition itself disputes, Kaviratna recording Gangadhara's dissent on mandukaparni in a footnote. The structural parts of the theory remain untested in anything retrieved here: the shodhana precondition that both principal texts make a gate on administration, the achara rasayana passage, and whether the classical grouping picks out drugs sharing any property. And the yardstick is stated plainly in the texts now quoted, which promise a hundred years of retentive memory, verbatim recall on a single hearing, and in one place five hundred years of life. Against that, a 45-day improvement in a DNA repair assay and an SMD of 0.52 on memory tests are not small results in the wrong direction; they are results about a different question. The honest position is that several rasayana substances have genuine randomised human evidence on short-term cognitive, anxiety and sleep endpoints, that one classical formulation has a single good placebo-controlled trial on a cellular surrogate, and that rasayana theory as a theory remains untested.","summary":"Rasayana is the branch of Ayurveda concerned with measures taken to improve the quality of the bodily tissues rather than to remove a disease. Charaka defines it etymologically as the means of imparting superior rasa and the dhatus derived from it, and attaches a list of claimed outcomes. The exact content of that list is translation-dependent and this record now carries two renderings of it rather than one (see contested). It is delivered either as an intensive indoor regimen in a purpose-built chamber (kutipraveshika) or as a method pursued without such seclusion (vatatapika); Charaka names both at aphorism 16 of the rasayana lesson, and no statement ranking one above the other was found in Kaviratna's text of that lesson. Both classical authorities require prior purification: Sushruta compares rasayana given to an uncleansed body to dyeing a dirty cloth, and Charaka's first pada makes a cleansed bowel the physician's precondition for administering it. Vajikarana is not a separate subject appended to rasayana but is defined inside the same lesson, as the second of the two kinds of medicine that increase the ojas of a healthy person. The tradition also extends the category to conduct (achara rasayana), though on Kaviratna's text the passage describes a person whose conduct qualifies him as a user of rasayana and whose faults, uncast off, would stop rasayana working; the stronger reading, that conduct alone substitutes for the drug, is Kaviratna's footnote rather than his translation of the verses. Modern research has largely reinterpreted the category as antioxidant and immunomodulatory pharmacology of individual formulations, which is a substitution of subject matter rather than a test of the theory, though the single-herb rasayana dravyas carry a human randomised literature with cognitive and clinical endpoints that polyherbal-formulation research does not.","contested":[{"question":"Is prior shodhana actually necessary for rasayana to work?","positions":["Sushruta's chapter 27 states it categorically, with the dyed-cloth analogy as justification. Charaka's first pada states it too, and now with a quote: the physician administers the formulation having ascertained that the bowels have been properly cleansed (Kaviratna aphorism 27). The record previously asserted the Charaka parallel without a citation; it is now sourced.","The rasayana trials located here administered the formulation or extract without prior purification, and several reported positive results, which is at minimum in tension with the classical rule.","No study located compared rasayana with and without preceding shodhana, so the claim is neither confirmed nor refuted by the work retrieved here; that literature simply proceeds as if the rule were not there."]},{"question":"Is rasayana a pharmacological category or a regimen?","positions":["The classical framing makes the regimen constitutive, with the formulation as one element. The quoted Sushruta medhya chapter is explicit: prior cleansing, prescribed diet order, entry into a chamber and mantra recitation a thousand times are written into each individual preparation, not appended to it. Charaka specifies the chamber's siting, walls, windows and auspicious entry at aphorisms 17 to 23.","Modern research treats rasayana as a set of formulations or, increasingly, single standardised extracts, and studies them as drugs, discarding the regimen entirely.","Sushruta's vajikarana chapter lists the means of vajikarana as food, 'speech that gladdens the ears', touch, moonlit nights, song, company and 'a merry careless heart', with no drug among them, which is direct textual evidence that the paired category is not conceived pharmacologically either.","Achara rasayana is often cited as the sharpest evidence for the non-pharmacological reading, on the ground that conduct with no drug at all produces the effect. That reading is now contested within this record: see the following question. No study of achara rasayana as an intervention was located."]},{"question":"Does achara rasayana claim that conduct replaces the drug, or that conduct conditions it?","positions":["Conduct replaces the drug. This is Kaviratna's footnote to the passage: 'Such a person does not require the aid of any Rasayana of drugs. He attains, through his conduct, to all the effects of Rasayana.' It is the reading this record previously carried, in its summary, its component gloss and its contested section, attributed to Charaka.","Conduct conditions the drug. This is what Kaviratna's translation of the verses themselves says. The person of such conduct 'should be known as a user of Rasayana' (52-56); he who has these attributes AND uses rasayana enjoys all its enumerated effects (57); he who has not cast off his graver faults never reaps them (58); the combinations succeed with those cleansed in mind and body (59). On this reading achara rasayana is continuous with the shodhana requirement rather than an alternative to pharmacology.","The disagreement is a translator's footnote against the translator's own text, which is the fourth instance in this project of the defect where a translator's voice is absorbed as doctrine. It is recorded here rather than resolved. Settling it requires the Sanskrit of Charaka Chikitsasthana 1, fourth pada, which was not retrieved, and ideally Chakrapani's commentary; Kaviratna also notes at aphorism 58 that he believes Gangadhara has misunderstood the couplet, so the commentarial tradition is not unanimous either."]},{"question":"Which English rendering of Charaka's rasayana outcome list is correct?","positions":["The record's former summary listed: long life, memory, intelligence, freedom from disease, retained youth, lustre, complexion, voice, strength of body and senses. That wording came from the verse-numbered edition at carakasamhitaonline.com, which is in copyright and was never quoted, so the list was a paraphrase of an unquotable source.","Kaviratna's public-domain translation has: longevity of life, memory, apprehension, health, youth, brightness, complexion, excellence of voice, great strength of body and the senses, power of making speech true, bows (from others), and comeliness of features. Three items have no counterpart in the record's former list, and 'apprehension' and 'health' are materially weaker than 'intelligence' and 'freedom from disease'.","Per the project's rule that disagreement between renderings is the data rather than a problem to resolve, both are recorded and neither is adopted as the record's own. Which is closer to the Sanskrit cannot be stated from what was retrieved here: no Sanskrit text of this passage was consulted."]},{"question":"What plants do the classical medhya rasayana names denote, and does the single-herb trial literature test them?","positions":["Kaviratna's 1890s identifications, printed inline with the Charaka passage, are mandukaparni as Hydrocotyle asiatica and shankhapushpi as Pladera decussata. These are the translator's botanical attributions, not the text's.","Kaviratna's own footnote records that Gangadhara identifies mandukaparni as danti, Baliospermum montanum, a quite different plant, so the identification is disputed inside the commentarial tradition.","Current usage differs again: mandukaparni is generally taken as Centella asiatica and shankhapushpi most often as Convolvulus pluricaulis, while brahmi is widely identified with Bacopa monnieri and sometimes with Centella asiatica, the two names being used interchangeably in some regions and for different plants in others.","This bears directly on the modern evidence. The Bacopa systematic review and the Withania meta-analyses are the strongest designs in this record, and whether they are evidence about a classical medhya rasayana drug at all depends on which identification is right. The record does not resolve this and does not treat those trials as tests of the classical drugs."]},{"question":"Do the classical rasayana formulations share any common active principle?","positions":["The antioxidant hypothesis, dominant in the modern literature, treats them as a class unified by free-radical scavenging.","The classical grouping is by claimed effect, not by composition, and includes items as different as amalaki preparations, bhallataka preparations, shilajatu, metals including gold and iron, and conduct. No source located demonstrates a shared mechanism across the classical list."]},{"question":"Where does the kamya / naimittika / ajasrika classification come from?","positions":["It is very widely presented in contemporary Ayurvedic writing as a Charaka classification.","It was not found in the retrieved verse-numbered edition of Charaka's Rasayana Adhyaya, nor in the public-domain Kaviratna text of that lesson now read in full for this record, which is consistent with it being a commentarial or later nibandha systematisation. Sources that attribute it directly to Charaka should be treated with caution. The search behind this was a reading of one lesson in one translation plus a keyword search of its OCR, which can support 'not found here' and cannot support a claim about the whole Charaka corpus."]}],"notKnown":["Whether any rasayana produces the specific classical outcomes over the timescales the texts name. This item previously read 'No trial with a clinical longevity or cognitive endpoint over a relevant timescale was located', and the first half of that was a search failure reported as an evidence gap: randomised human trials with validated cognitive endpoints exist for single rasayana dravyas and are now cited in this record. The gap that survives is narrower and still real.

No statement ranking the two methods was found in Kaviratna's text of Charaka's rasayana lesson, where the two are named at aphorism 16 and elaborated only in the translator's footnotes, so the record no longer attributes the comparative claim to the text. Whether another classical text asserts it, and whether the comparison has ever been made experimentally, are both unknown here.","Whether achara rasayana does anything. No study located. And, now, what achara rasayana claims in the first place: the drugless-substitute reading is Kaviratna's footnote and his translation of the verses reads the other way, so the question of what would even be under test is open.","Whether the effects seen with Amalaki rasayana or Chyawanaprash persist after the formulation is stopped, or reflect only nutritional repletion in the study populations.","What dose, duration and preparation method are required, and whether classical preparation procedure matters.

Scoped out rather than filled with a general statement.","Whether standard Trikamji verse numbering agrees with Kaviratna's printed aphorism numbers at the locations cited here. Kaviratna prints his number after the aphorism and is documented in this project as running one behind Trikamji through at least Chikitsasthana 15 and Vimanasthana 5 and 8. At Chikitsasthana 1 his numbers for the definition passage (7-8) and the two methods (16) coincide with the numbers this record previously carried from a verse-numbered edition, and his number for the medhya drugs (34-35) does not coincide with the 1.3.30-31 commonly cited for that passage.

That is not in dispute, and it is not an Ayurvedic proposition. Dopico 2015 found seasonal expression profiles in more than 4,000 protein-coding mRNAs in white blood cells and adipose tissue; Ter Horst 2016 found annual seasonality in stimulated cytokine responses across 534 healthy subjects; Sheth 1999 found January peaks in myocardial infarction and stroke mortality across 300,000 Canadian deaths. None of the three was designed to test ritucharya, none uses the six-season division, and none measures anything corresponding to vata, pitta or kapha. Offering them as support for 'the premise behind ritucharya' credits the classical scheme with evidence it has not been given, so this record does not offer them that way. The generic claim these papers support is one nobody disputes; the Ayurvedic claim is the specific one, that physiology varies in the particular doshic pattern Charaka Sutrasthana 6 and Sushruta Sutrasthana 6 assert, with the two half-years as the driver, and no reference here speaks to that. Two of the three point away from a calendar-fixed regimen rather than towards one. Dopico's seasonal expression pattern is inverted between Europe and Oceania, and the blood-composition changes that might explain it differ between the United Kingdom and The Gambia; an effect whose sign depends on latitude is evidence against a fixed six-season calendar anchored to north India being the operative variable. Ter Horst's cohort is single-site Dutch and carries no latitude information at all. Sheth's winter peak is a Canadian winter, in months that Sushruta's scheme splits across hemanta and shishira. Nothing retrieved here tests the scheme itself: not the six-season division, not the dosha-to-season assignments, not the chaya-prakopa-prashama sequence, not ritusandhi, not the claim of spontaneous seasonal remission, and none of the per-season dietary or behavioural prescriptions. What the searches returned is set out with dates and hit counts in modernCoverage.searchBound: a Europe PMC query for 'ritucharya' on 2026-10-06 returned 68 records, of which exactly one carries the publication type 'Controlled Clinical Trial', and that one tests a prophylactic polyherbal kit rather than a seasonal regimen; the same query restricted to publication type 'Randomized Controlled Trial' returned nothing. Sixty-seven of those 68 were read as metadata only. On that basis this record states what those searches returned and does not state that no trial exists, and the Ayurvedic-side pattern it can report is the one its own references show: narrative reviews that restate the classical scheme in the vocabulary of chronobiology or the gut microbiome, propose a biomarker or a microbiome study as future work, and stop, of which the gut-microbiome review cited here, not even PubMed-indexed, is the clearest example. The honest summary is that ritucharya is a classically coherent scheme resting on a real and generic phenomenon, with no modern test of the scheme itself, and with the one latitude-resolved modern finding pointing against its calendar being exportable.","summary":"Ritucharya is the classical prescription that diet and conduct be changed with the season. The rationale, as the retrieved passages state it, has three parts. First, the year is divided into two solar half-years, adana (the sun's northern course, when the sun and dry winds take up moisture and human strength declines) and visarga (the southern course, when moisture is restored and strength increases), each subdivided into three two-month seasons. The causal chain the texts give is environmental before it is doshic: solar and wind action alters the qualities of water and plants, which alters food, which alters the body. Second, the doshas are held to run a three-stage cycle keyed to season: accumulation (chaya) in one season, aggravation or manifestation (prakopa) in the next, and subsidence (prashama) in a third. Whether the regimen for a season is therefore aimed at the dosha accumulating in it or at the one manifesting in it is NOT settled by the passages retrieved here: Charaka's autumn prescription reads as anticipatory, Sushruta's chapter closes by directing that the deranged dosha be checked in the season of its prakopa before it manifests as illness, and the two are not reconciled in anything retrieved. See contested. Third, suitability is defined relationally: what is appropriate is what has qualities contrary to those of the place of habitation and of the existing disorder, though Kaviratna footnotes a textual variant at exactly that verse (see notKnown). The seasons named are those of the north Indian calendar, defined by named lunar months, and the texts do not address latitudes where that calendar does not apply.","contested":[{"question":"Where do the boundaries of adana and visarga fall, and which season starts the year?","positions":[{"view":"Charaka's Sutrasthana 6 runs adana from the dewy season (shishira) through summer, and visarga from the rains through hemanta, and describes the seasons in that order.","source":"Charaka Samhita, Sutrasthana 6, prose aphorisms 1-2 in Kaviratna's edition, quoted in full in this record.

The classical footing is solid and now verified in three texts rather than one. Ca.Su.11/48 defines all three pathways; Ca.Su.11/49, a single aphorism, populates each with named diseases and names five of them twice, once as following shakha and once as following koshtha, which is the dual-pathway group; Ca.Su.28/31-33 supplies the doshagati mechanism by which doshas move outward from koshtha to shakha and back, with Chakrapani glossing the shakha of that chapter as the dhatus. Vagbhata states the same scheme independently at A.H.Su.12/44-49, defining shakha in Charaka's own words, agreeing with Charaka on koshtha, naming the madhyama rogamarga in the text, and splitting the dual-pathway diseases into outer-part and inner-part varieties instead of assigning them twice. Sushruta's koshtha at Su.Ci.2/12-13 is wider than either and includes the seat of blood along with the heart, unduka and lungs, which leaves the koshtha-shakha boundary genuinely unsettled rather than merely unclear, since rakta itself is assigned to shakha. What the texts do not contain, so far as this record could retrieve them, is the prognostic ranking the tradition is most often quoted for. Ca.Su.11/48-49 states membership and says nothing about difficulty of cure; A.H.Su.12/44-49 likewise. Ca.Ci.28/72-74 does attribute poor prognosis to depth of seat for a list of vata disorders that overlaps the madhyama list, but it never uses the word rogamarga and does not rank the pathways. The attributions of the ranking run to commentators, Chakrapani for the general claim that roga-marga serves prognosis and Gangadhara for the specific ruling that madhyama-marga disease is krichhra-sadhya or yapya, and neither commentary was retrieved in the original here, so neither is cited. The modern position is close to empty. A PubMed E-utilities search on 2026-10-06 returned zero records for 'rogamarga', for 'roga marga ayurveda' and for 'roga-marga'; every modern reference in this record that bears on roga-marga directly sits in non-indexed Indian Ayurveda journals, and the two PubMed-indexed references bear on the concept only by implication. That literature is dominated by narrative reviews that restate the three lists and then propose an analogy, most often to physiological compartmentalisation, without testing it. One cross-sectional study of 100 outpatients was found, and it reports a pathway distribution with an age gradient that it has no design to distinguish from ordinary epidemiology. No study was found in this search that measures whether two clinicians assign the same patient to the same pathway, whether pathway assignment predicts outcome or difficulty of cure, or whether the therapeutic rule derived from doshagati improves anything. The concept as it stands is a classical topographic taxonomy, attested in three samhitas and in continued teaching use, whose central prognostic claim is commentarial rather than textual and which has no published test of either its prognostic or its therapeutic claims.","summary":"Roga-marga is Charaka's division of the body into three pathways along which disease settles. Shakha, the outer pathway, is rakta and the other dhatus together with the skin, and is called the bahya marga. Marma and asthi-sandhi, the vital points, Charaka's Sanskrit names basti (bladder), hridaya and murdha, together with the junctions of the bones and the snayu and kandara bound to them, form the madhyama or middle pathway. Koshtha, the great internal cavity, named in Ca.Su.11/48 as the mahasrotas, the middle of the body, the mahanimna and the amashaya and pakvashaya, is the abhyantara or internal pathway. Diseases are assigned to a pathway by where they manifest: goitre, pustules, skin disease and superficial growths to shakha; hemiplegia, convulsive disorders, facial palsy, wasting, bone and joint pain, prolapse of the rectum and diseases of head, heart and bladder to the middle pathway; fever, diarrhoea, vomiting, cholera, cough, dyspnoea, hiccup, abdominal disease and spleen disease to koshtha. Five conditions, visarpa, shvayathu, gulma, arsha and vidradhi, are named twice in the same aphorism, once as following shakha and once as following koshtha, which is the ubhaya-marga or dual-pathway group. The scheme is presented in the commentarial and teaching tradition as prognostic and therapeutic rather than merely descriptive, and the convention that the middle pathway is the hardest to cure is repeated across the modern reviews; this record was unable to locate that ranking in any verse of Charaka, Vagbhata or Sushruta that it could retrieve, and records it as commentarial convention rather than as text (see contested[3] and notKnown). Its mechanism rests on doshagati, the movement of doshas between koshtha and shakha, stated at Ca.Su.28/31-33.","contested":[{"question":"What exactly does shakha cover?","positions":["The dhatus plus skin, i.e. a tissue compartment. This is what Ca.Su.11/48 states, 'shakha raktadayo dhatavas tvak ca', and what Kaviratna's footnote spells out, and Vagbhata gives the identical definition at A.H.Su.12/44, 'shakha raktadayas tvak ca'. Two texts, same words.","The limbs and periphery, in the ordinary sense of the word 'branch'. This is how the term is often used loosely in clinical teaching. No source consulted here states it as the definition of the bahya rogamarga, and both texts that do define it define it the other way.","Whether the shakha of the doshagati passages at Ca.Su.28/31-33 is the same shakha as Ca.Su.11/48 is a real question, but it cannot be settled from the English. The Sanskrit uses the same word in both places, and Chakrapani on 28/31 glosses the destination as rasa and the rest, 'rasadinam shakharupatvat', which identifies it with the dhatus. On the evidence retrieved here the two uses agree."]},{"question":"What is the extent of koshtha?","positions":["The alimentary cavity. Ca.Su.11/48 gives mahasrotas, sharira-madhya, mahanimna, amashaya and pakvashaya. A.H.Su.12/46 gives 'antah koshtho mahasrota ama-pakvashayashrayah', which agrees. Kaviratna's footnote extends it to the bladder, the aorta, the lungs and the juices of liver and spleen, but that extension is his, not the verse's.","A wider internal territory. Su.Ci.2/12-13, now quoted at classical[7] from Bhishagratna, lists the seats of ama, agni, pakva, mutra and rudhira, plus the heart, the unduka and the lungs, as koshtha. Four of those eight are not in Charaka's or Vagbhata's definition.","The two definitions are not reconcilable at the boundary. Charaka assigns rakta to shakha and Sushruta assigns the reservoir of blood to koshtha, so on the combined reading the same tissue falls on both sides. Nothing retrieved here resolves which definition the roga-marga scheme is supposed to use, and the roga-marga scheme is Charaka's."]},{"question":"How should the dual-pathway (ubhaya marga) diseases be understood?","positions":["Membership is a property of the episode, not of the disease. Ca.Su.11/49 names visarpa, shvayathu, gulma, arsha and vidradhi twice inside one aphorism, as shakhanusarinah and again as koshthanusarinah, with no qualifier distinguishing two kinds of each.","They are separate outer and inner varieties of conditions that share a name. This is Vagbhata's reading and he states it in the text: A.H.Su.12/45 assigns the 'bahirbhaga', outer-part, varieties of durnama, gulma and shopha to shakha, and A.H.Su.12/47 assigns the 'antarbhaga', inner-part, varieties of shopha, arsha, gulma, visarpa and vidradhi to koshtha.","The category is a residue of a taxonomy that does not partition cleanly, which weakens the claim that pathway assignment is informative.","Charaka and Vagbhata therefore disagree about the same five diseases, and the disagreement is in the Sanskrit rather than in anyone's translation. Whether Vagbhata is interpreting Charaka or departing from him is not addressed by any source consulted here."]},{"question":"Is the middle pathway really the hardest to cure?","positions":["The standard teaching position, repeated across the modern reviews, is that madhyama-marga diseases are the most difficult, often phrased as krichhra-sadhya or yapya.","No verse stating it was located. This revision searched the three places the audit named. Ca.Su.11/48 and 11/49 were retrieved in full in the Sanskrit and quoted at classical[0], [2], [3] and [4]; they state membership and contain no prognostic term. A.H.Su.12/44-49 was retrieved in full in the Sanskrit and quoted at classical[6]; it contains no prognostic term either. Ca.Ci.28/72-74 was retrieved and is quoted at classical[8]; it does say that a list of vata disorders overlapping the madhyama list 'may or may not be cured even with effort' because of the depth of the seat, but it never uses the word rogamarga and does not rank the three pathways.","The claim's provenance is commentarial. The modern critical edition at carakasamhitaonline.com reports Chakrapani on Ca.Su.11/48 as giving the purpose of the roga-marga section as knowing prognosis, which is weaker than a ranking; the reviews attribute the ranking itself to Gangadhara. Chakrapani's commentary on Su.11 is not in the GRETIL Caraka excerpt, which covers only Sutrasthana 1-3, 5, 6 and 26-28, and Gangadhara's Jalpakalpataru was not retrievable here. Neither is quoted, so neither is cited.","Its status in this record is therefore: conventional, attributed to commentators, not located in any samhita verse retrieved, and not tested. The searches that justify the words 'not located' are the four named above and nothing wider."]},{"question":"Does roga-marga correspond to any modern physiological division?","positions":["Yes, to compartmentalisation, alimentary, intravascular, interstitial, intracellular (AYUSHDHARA 2023, modern[1]).","No: the three pathways group diseases by manifest site, not by any single physiological axis, and the dual-pathway group shows the taxonomy crossing whatever boundary is proposed.","Any such mapping has to choose a definition of koshtha first, and the texts do not agree on one. Charaka's and Vagbhata's koshtha is alimentary; Sushruta's includes the blood reservoir, the heart and the lungs, which would land in a different compartment on the proposed scheme.","The mapping has never been tested, so all of the above are currently assertions."]}],"notKnown":["No samhita verse ranking the three pathways by difficulty of cure was located. This is the single most-repeated clinical claim about the concept, and the searches run for it were: the full Sanskrit of Ca.Su.11/48 and 11/49, the full Sanskrit of A.H.Su.12/44-49, and Ca.Ci.28/72-74. None contains a prognostic term applied to a rogamarga. The claim is attributed in the modern literature to Chakrapani and to Gangadhara. Chakrapani's commentary on Ca.Su.11 is not in the only machine-readable Caraka commentary text available here, and Gangadhara was not retrievable at all, so whether either commentator states the ranking in the form the reviews give is unverified. A wider search of printed commentary editions would settle it and has not been run.","Whether Ca.Ci.28/74's principle, that depth of seat makes cure uncertain, was intended as the same doctrine as the roga-marga ranking is not stated by any source consulted. The verse is about vata-vyadhi sites, the overlap with the madhyama list is partial, and treating the two as one claim would be the record's inference and not a source's.","Whether two clinicians independently assign the same patient to the same roga-marga has not been measured in anything found in this search.

On the texts, the concept is now sourced in three samhitas and nineteen citations, of which eighteen carry a quote. Charaka states the fourfold scheme at Ca.Su.10/9, grades the curable again by magnitude of means at 10/10, and then gives a separate criteria list for each of the four tiers at 10/11-20, built from a recurring set of variables whose values shift across the tiers: force of causes and signs, correspondence of dosha with dushya, prakriti, season and place, number of doshas, number of pathways, depth of seat, marma and sandhi involvement, duration, complications, tolerance of medicines, and completeness of the four padas. That block is the most detailed prognostic rule in either samhita and the record did not have it at gathering, which is why it previously credited Sushruta with the nearest thing to an operational rule. Charaka restates the scheme independently at Ca.Su.18/39-41, where yapya is named in the verse. Sushruta's three tiers and his criteria are at Su.Su.35, and Su.Su.23 shows the three tiers applied to one disease class with a named yapya block. Vagbhata compresses the whole thing into A.H.Su.1/29+(1) to 1/35. The arishta material is Charaka's twelve Indriya Sthana chapters, Sushruta Su.Su.28 to 33, and A.H.Sharirasthana 5. The two bodies are joined inside the text: Charaka's refusal criteria at Ca.Su.10/20 include sarishtam, Vagbhata's at A.H.Su.1/33 include drishta-rishta, and Sushruta closes his arishta block at Su.Su.32 by saying that the physician who can read the fatal signs is honoured by the king for determining whether a disease is curable or incurable. Three separate loci therefore state the purpose of the arishta chapters to be the sadhya-asadhya judgement, which the record previously asserted as its own reading. The doctrine has an internal feature that resists testing, and it is in the Sanskrit rather than in anyone's English: Ca.In.2/5 says no arishta once arisen vanishes other than by death and no death is unpreceded by one, and 2/6 assigns both false positives and false negatives to prajnaparadha. But Vagbhata reports a qualification the record did not have. At A.H.Sha.5/3-4 he says that some hold rishta to be twofold, sthayin and asthayin, and that a mere abundance of doshas can produce a rishtabhasa, an appearance of a rishta, which subsides when the doshas are pacified, while the persistent one goes inevitably to death. That is a prospectively applicable criterion, and it narrows the self-sealing reading without dissolving it. On the modern side, nothing was found in the indexes searched that tests any part of the concept, and the searches are named in full in searchRecord rather than summarised. PubMed E-utilities was run on 2026-10-06 with seventeen strings, DHARA with ten, and the AYUSH Research Portal, which holds 30,920 Ayurveda records and is the largest relevant index, failed server-side on every attempt with its own tempdb error and has therefore not been searched at all. Scopus, Web of Science, Embase, CENTRAL, Google Scholar, any Hindi or Devanagari search, and any hand-search of non-indexed Indian Ayurveda journals were not attempted. Within those bounds: changing the search string recovered three on-topic indexed records the record had missed, so the record's previous claim that there is no modern evidence base was not merely unbounded but wrong in part. One of the three, a 1997 paper in Ancient Science of Life, states the classical ruling that kaphaja prameha is sadhya and pittaja and vataja are yapya and asadhya, and sets out to test it against insulin level; its retrievable abstract reports an aim and no results, so it establishes that the attempt exists and nothing more. Another is a commentarial study of arishta-vijnana in Dalhana and Chakrapani, which shows that the scholarly literature on the arishta material is substantial and that this record has consulted none of it in the original. The strongest material actually in hand remains indirect: the knee-osteoarthritis reliability study, which shows that Ayurvedic experts agree poorly on the diagnostic inputs a prognostic judgement would be built from, and the three oil-drop papers, of which the 2012 one is a standardisation protocol whose own premise is that the technique is crude and variable. Zero of the ten modern references report a sadhya, yapya or asadhya assignment tested against an outcome, an agreement statistic for any prognostic category, or sensitivity, specificity or a c-statistic for any arishta sign. That is the honest summary of the modern position, and it is a statement about these searches rather than about the world. This revision also added three comparators from conventional medicine, because the defensible claim is not that no evidence exists but that the test has not been done and this is what it would look like. Christakis and Lamont (2000) measured clinician prognostic accuracy directly: 20 per cent of 468 predictions accurate, 63 per cent overoptimistic, survival overestimated by a factor of 5.3. The Surprise Question meta-analysis (2017) reports pooled accuracy of 74.8 per cent over 25,718 predictions with c-statistics from 0.512 to 0.822, which is the form a single clinician-rated death sign has to be reported in to be assessable at all. The Palliative Prognostic Index meta-analysis (2025) does the same for a composite score built from weighted features, which is the form Charaka's and Sushruta's criteria lists take. Together they show that the quantity the arishta chapters claim to deliver is one conventional medicine also attempts and is measurably poor at, so the comparison is not between a tested method and an untested one; it is between a method whose error has been quantified and one whose error has not. What remains most in need of explicit treatment in any modern reference is the ethical content, and this revision sharpened it rather than softening it. Charaka's disclosure rule at Ca.In.12/62-64 directs the physician to withhold a terminal prognosis and decline the case without saying why, and at 12/65 it directs him to declare recovery with certainty when the contrary signs appear, so it is a one-way restriction and not a general reticence. Vagbhata's refusal list at A.H.Su.1/34-35 is wider still and eleven of its twelve grounds are not prognostic: political disfavour, lack of means, distraction, non-compliance, violence, grief, timidity, ingratitude, and thinking oneself a physician. Every reason the three texts give for getting the prognosis right is a reason of the physician's standing: loss of wealth and fame at Ca.Su.10/8, infamy and loss of one's own interest at A.H.Sha.5/1+(2), professional success at Su.Su.33, and the king's honour at Su.Su.32. This is the part that is incompatible with contemporary informed-consent and palliative-care practice, and no source consulted reconciles them.","summary":"Sadhya-asadhya is the classical requirement that the physician determine, before beginning treatment, whether a disease is curable, manageable but not curable, or beyond treatment. Charaka divides diseases into sadhya (curable) and asadhya (incurable), each into two: curable easily or with difficulty, and incurable but suppressible (yapya) or without treatment at all (anupakramya, pratyakhyeya). He states this at Ca.Su.10/9 and then, at Ca.Su.10/11-20, gives a graded list of criteria for each of the four. That criteria block is the most detailed prognostic rule either samhita contains, and this record did not carry it at gathering. Charaka restates the scheme at Ca.Su.18/39-41, where yapya is named in the verse and curability is crossed with mildness and violence to give four kinds. Sushruta gives three working categories, curable, yapya and incurable, at Su.Su.35, and specifies the features that make a disease yield to medicine: recent onset, absence of distressing complications, mismatch with the patient's country, season, temperament and habituation, intact digestion, and the presence of strength and fortitude. He applies the same three tiers to one disease class at Su.Su.23, where a named block of yapya ulcers admits palliation only. Vagbhata compresses the whole scheme into Ashtanga Hridaya Sutrasthana 1/29+(1) to 1/35. The classification carries a strong professional injunction. Charaka warns at Ca.Su.10/8 that a physician who treats an incurable case loses wealth, knowledge and fame and incurs the censure of the world; Sushruta at Su.Su.33 tells the physician to abandon patients with named fatal complications; and Vagbhata at A.H.Su.1/34-35 lists the patients to be given up, most of them named for reasons that are not medical at all. A parallel body of material, the arishta lakshanas of Charaka's Indriya Sthana, twelve chapters whose titles are enumerated in components, and Sushruta Sutrasthana 28 to 33, catalogues signs of impending death; Vagbhata's counterpart is Sharirasthana 5. The two bodies are joined inside the text itself, because Charaka's criteria for refusal at Ca.Su.10/20 include sarishta, the disease accompanied by arishtas, and Vagbhata's at A.H.Su.1/33 include drishta-rishta. Charaka also lays down a disclosure rule at Ca.In.12/62-64: the physician should never say unasked that death is near, should not say so even when asked if the declaration would cause harm, and should instead decline the case without saying why. The rule is asymmetric; at Ca.In.12/65-66 the physician is told to declare recovery when the contrary signs appear.","contested":[{"question":"Is the classification three-fold or four-fold?","positions":["Three: sadhya, yapya, asadhya. This is Sushruta's formulation at Su.Su.35 (classical[11]) and the one used in most teaching.","Four: sukhasadhya, kricchrasadhya, yapya, anupakramya/pratyakhyeya. This is Charaka's at Ca.Su.10/9 (classical[1]) and Vagbhata's at A.H.Su.1/29+(1) (classical[17]), in the same terms in both.","Charaka elsewhere crosses curability with severity to produce a different four, mild-curable, violent-curable, mild-incurable and violent-incurable, at Ca.Su.18/41 (classical[6]). The three schemes are routinely presented as one, which they are not.","Arguably more than four, since Ca.Su.10/10 divides the curable again by whether the means required are alpa, madhyama or utkrishta (classical[2]). Charaka therefore has at least five grades of sadhya-ness within the curable alone, and the record's own earlier count of four was itself a simplification."]},{"question":"Is refusing an incurable case an ethical duty or professional self-protection?","positions":["The texts give the reason in self-interested terms, and this revision found that all four places they do so agree. Ca.Su.10/8 lists artha, vidya, yasha, upakrosha and asangraha, all costs to the physician. A.H.Sha.5/1+(2) says treatment in one whose life-span is exhausted yields ayashas and svartha-hani, infamy and loss of one's own interest. Su.Su.33 says the physician 'with any regard to professional success' should abandon such a patient. Su.Su.32 says the physician who can read the fatal signs is honoured by the king for determining curability. Four loci, four reasons, none of them about the patient.","Modern Ayurvedic commentary reframes pratyakhyana as honesty about limits and avoidance of futile burdensome treatment, closer to a palliative-care rationale. Both readings are defensible from the text, but they are different rationales and the texts state the first.","Vagbhata's refusal list at A.H.Su.1/34-35 (classical[17]) makes the self-protection reading harder to avoid, because most of it is not about prognosis at all. The physician is to give up the patient who is hated by physicians and kings, who hates them, who is hinopakaranam (lacking means), vyagram (distracted), avidheyam (non-compliant), chandam (violent), shokaturam (grief-stricken), bhirum (timid), kritaghnam (ungrateful) or vaidyamaninam (thinks himself a physician). Only gatayusham, one whose life-span is gone, is a prognostic ground. Whatever pratyakhyana is in Charaka, in Vagbhata it is partly a rule about which patients are worth taking on.","A third reading is possible and is not the same as either: that the texts are describing a reputational economy rather than prescribing one, i.e. recording what a physician who wished to keep a practice in that setting had to do. No source consulted here argues this, and this record does not assert it; it is listed because the first two positions are usually presented as exhausting the options and they do not."]},{"question":"Should a terminal prognosis be disclosed?","positions":["Charaka Ca.In.12/62-64 (classical[9]): never unasked, not even when asked if harm would follow, and decline without explaining.","The rule is one-directional, which the record did not previously state. Ca.In.12/65 (classical[10]) tells the physician to declare recovery dhruvam, with certainty, when the signs contrary to the death-signs appear. So the text is not reticent about prognosis as such; it withholds bad news and gives good news positively. This makes the conflict with informed consent sharper, not softer, because the asymmetry is itself the thing modern consent doctrine objects to.","Contemporary medical ethics and the informed-consent framework under which registered Ayurvedic practitioners operate in India require disclosure to a competent patient who asks. The classical rule and current professional obligation conflict, and no source consulted resolves this.","The classical rule's own stated ground is harm, 'tatra yatropaghatakam', where it would be injurious, which is recognisably a therapeutic-privilege argument and is not simply evasion. That does not reconcile the two, because modern consent doctrine has largely rejected therapeutic privilege as a default, but it does mean the disagreement is about whether the privilege holds rather than about whether patients matter."]},{"question":"Do arishta signs have prognostic content?","positions":["The tradition treats them as reliable, on the strength of long clinical observation; Kaviratna's own preface remarks that experience seems to confirm many of Punarvasu's observations. That remark is the translator's and is recorded as such.","No sign has been evaluated prospectively in anything found in the searches named in searchRecord, and several arishta chapters concern dreams, omens, the conduct of the messenger sent to fetch the physician, and incidents on the road, which are not observations about the patient at all. Ca.In.12/66 confirms this directly: the signs the physician may read recovery off include the messenger, omens on the road, the patient's household and the patient's property.","The doctrine's definition is self-sealing, and this is in the Sanskrit rather than in the English. Ca.In.2/5 says no arishta once arisen vanishes other than by death and no death is unpreceded by one; Ca.In.2/6 assigns both false positives and false negatives to prajnaparadha. A.H.Sha.5/2 says the same. On that definition clinical experience cannot discriminate between true and false arishtas.","But Vagbhata reports a qualification that is not post-hoc. At A.H.Sha.5/3-4 (classical[18]) he says 'ke-cit tu tad dvi-dhety ahuh', some say it is twofold, by the division into sthayin and asthayin: an abundance of doshas can produce a rishtabhasa, an appearance of a rishta, which subsides when the doshas are pacified, whereas the persistent one goes inevitably to death. Persistence through dosha-pacification is a criterion that can be applied before the outcome is known. It does not remove the circularity, since the persistent sign is still fatal by definition, but it means the tradition is not uniformly committed to the unfalsifiable version, and the record's flat statement that it is was too strong.","What would settle it is not in dispute and has simply not been done: a prospective cohort reporting, for each named sign, sensitivity, specificity and a time horizon, in the form the Surprise Question literature uses (modern[8]). Until then the question is open rather than answered in either direction."]},{"question":"Is yapya a useful category today?","positions":["It maps naturally onto chronic disease management and is cited as evidence that Ayurveda distinguished control from cure long before modern medicine did.","The mapping is loose: Sushruta's eight 'hard to cure' conditions at Su.Su.33 include several (ashmari, bhagandara, some udara) that are now routinely curable surgically, so the category's membership is not stable across time.","The claim that yapya is defined only negatively, by the failure of cure, is no longer tenable in the form the record previously stated it. Ca.Su.10/17-18 gives positive criteria: remaining life-span, a small ease gained from wholesome regimen, a slight cause restarting the condition, depth of seat, many dhatus, marma and sandhi involvement, continuous presence, long duration, two doshas. Ca.Su.18/39 adds a positive functional definition, that treatment well done becomes yatrakara, enabling the patient to go on. Whether those criteria can be scored reproducibly is a separate and open question; that they exist is now sourced.","A sharper difficulty than the negative-definition one is that the criteria are time-indexed to therapeutics. 'Beyond the path of treatment' at Ca.Su.10/19 and 'needing surgery, alkali or fire' at Ca.Su.10/15 are both statements about what the available means can reach, so the boundary between kricchrasadhya, yapya and pratyakhyeya moves whenever the means change, and the texts give no updating rule. See notKnown.","Su.Su.35's second sentence adds a different instability: each of the three tiers is to be examined for whether the disease is primary, aupasargika (accessory or sympathetic to something else), or the premonitory sign of something incipient. A yapya condition that is actually aupasargika is not a stable member of the class, because its course is governed by the primary disease."]}],"notKnown":["Whether a sadhya/yapya/asadhya assignment predicts survival or recovery. NARROWED. The record previously said 'No prospective cohort has ever tested this'. One attempt was found, modern[3], a 1997 paper in Ancient Science of Life that states the classical ruling on prameha (kaphaja sadhya, pittaja yapya, vataja asadhya) and sets out to test it against insulin level; its retrievable abstract reports an aim and no design, sample size or results, and the full text was not obtained. What can be said is that no adequate test was found in the searches named in searchRecord, not that none has ever been attempted.","Whether two physicians assign the same patient to the same prognostic category. No inter-rater reliability study of prognostic classification was found in the searches run. The nearest datum, modern[6], shows poor agreement on the diagnostic inputs rather than on the prognostic output, which bounds the answer without giving it.","The sensitivity, specificity, positive predictive value, c-statistic or lead time of any individual arishta sign. None was found. The form such a report would have to take is now specified by comparison with modern[8], which reports exactly these quantities for a structurally similar single clinician-rated judgement.","Whether Charaka's criteria at Ca.Su.10/11-20 can be operationalised and scored reproducibly. This replaces the record's earlier item, which asked the question only of Sushruta's Su.Su.35 list because it did not have the Charaka block. The Charaka block is the harder case: it uses about a dozen variables with ordinal values and gives no weights, no thresholds and no combination rule. No instrument was found for either list. Modern[9] shows what a validated composite of this shape looks like in practice.","Whether the sthayin and asthayin distinction Vagbhata reports at A.H.Sha.5/3-4 was ever worked out into a usable rule, how long a rishta must persist through dosha-pacification to count as sthayin, and who the 'ke-cit', the some who say so, were. The verse reports the view and does not develop it, and no commentary on it was consulted here.","How the classification is meant to be revised as treatment changes. Several conditions listed as intrinsically hard to cure at Su.Su.33 are now surgically curable, and 'beyond the path of treatment' at Ca.Su.10/19 is explicitly indexed to available means. The texts give no updating rule and no source consulted supplies one.","Whether pratyakhyana as practised today leads to referral, to abandonment, or to delayed presentation to conventional care. No observational data on what actually happens to refused patients was found.","How the non-disclosure rule is handled in current practice under Indian consent law, and whether practitioners follow the classical rule, the modern rule, or something in between. No survey was found. The asymmetry now documented at Ca.In.12/65 makes this a sharper question than the record previously posed, because a practitioner could be following the classical rule precisely while appearing to disclose freely.","Whether Vagbhata's refusal list at A.H.Su.1/34-35 is read today as live guidance, as historical context, or as something to be explained away. Eleven of its twelve grounds are non-medical and one of them, hinopakaranam, is poverty. No source consulted addresses how it is taught.","Whether the oil-drop urine test measures anything. Its inter-observer reliability has still not been reported in anything found. NARROWED: the record previously said the reliability 'has never been reported', without noting that modern[2], a 2012 standardisation paper, states the problem in its own words ('the technique is very crude and there are chances of variations in the observations') and proposes a protocol intended to make observations reproducible. A protocol is not a reliability estimate, so the gap stands, but it is not an unexamined gap.","What Chakrapani's Ayurvedadipika on the Indriya Sthana, Dalhana's Nibandha Samgraha and Chakrapani's Bhanumati say about this material. Modern[4] reports that all three treat arishta-vijnana at length and that Chakrapani held Charaka's Indriya Sthana superior for it. None was read in the original here and none is cited. This is the largest classical gap left in the record, and it is the same gap recorded on the roga-marga record of this project.","Sushruta's threefold classification of ayu into dirghayu, madhyamayu and alpayu, which modern[5] reports with characteristics for each. The locus was not identified and the passage was not retrieved, so it is not cited. It is plainly adjacent to this concept, since the life-span judgement is what Ca.Su.10/17 makes yapya depend on, and it is recorded as a gap rather than paraphrased from the review.","Whether the prognostic material in Charaka's Vimana and Chikitsa Sthanas, which modern[5] names alongside Indriya and Sharira, adds anything to the four tiers. Those two sthanas were not searched.","Whether the AYUSH Research Portal holds work that would change any of the above. It holds 30,920 Ayurveda records, its search failed server-side on every attempt on 2026-10-06, and it has therefore not been searched.

The costs named are again the physician's. (3) 5/2 restates the unfalsifiable structure in almost Charaka's words: there is no death without arishta, no life where a rishta has been seen, and the misperception of rishta where there is none and the failure to perceive it where there is run 'a-naipunat', from lack of skill. (4) 5/3-4 is the part this record did not have and could not have inferred. Vagbhata reports an opinion, marked as an opinion, 'ke-cit tu tad dvi-dhety ahuh', but some say it is twofold: by the division into sthayin and a-sthayin, persistent and non-persistent. From a mere abundance of doshas a rishtabhasa, an APPEARANCE of a rishta, may arise; that one subsides when the doshas are pacified, whereas the persistent one goes inevitably to death. That is a criterion, prospectively applicable, for separating a true sign from a false one, and it is not post-hoc reclassification.

This revision separates what is addressable in text from what is evidentially supported, because running those together was the gathered record's central defect.\n\nWHAT IS ADDRESSABLE IN TEXT. Charaka's Nidana Sthana 1 defines samprapti by synonym (Ni. 1/11), divides it by five analytic heads (Ni. 1/12), and defines each of the five (Ni. 1/12.1 to 12.5). All of it is quotable from Kaviratna's public-domain translation and all of it is now numbered against the Trikamji Sanskrit rather than against a translator's own count or an unnamed 'modern edition'. The definitional run is the closest thing in the samhita to an operational definition, and it is worth being exact about what it operationalises: how to subdivide a pathogenesis once stated, not how to establish one, not how to choose between two, and not how to find one wrong. Charaka also gives a worked example in the fever chapter and the site-specificity principle at Su. 28/8 that the whole construct rests on.\n\nWHAT THIS RECORD NO LONGER CLAIMS. The gathered evidenceState called samprapti 'a well-attested doctrinal construct with clear textual loci in Charaka's Nidana Sthana and a long commentarial and teaching tradition'. The second half is cut. A teaching tradition is the replication of a syllabus; it is transmission, not corroboration, and a construct taught for a thousand years is not thereby better evidenced than one taught for ten. The cut also removes a conflation that the gathered record's own contested[1] already refuted. Calling the loci 'clear' is true of Charaka's five analytic heads and false of samprapti ghataka, the ten-to-twelve-item checklist that modern clinical writing actually operates under the name samprapti; the searches named in gatheringNotes found no classical verse enumerating that list, and no retrieved source gives it an author or a date. Describing both as one well-attested construct let a twentieth-century teaching artefact inherit Charaka's authority. The two are now reported as two things, in summary, in components and in contested[1]. Nothing was deleted to make the old claim survivable: the contested entry that exposed it stands untouched and has been strengthened.\n\nWHAT THE MODERN LITERATURE SUPPORTS. A PubMed search for 'samprapti' on 2026-10-06 returned 15 records. Those retrieved and read for this record are case reports, case series and narrative reviews that restate a classical pathogenesis for a modern disease label (psoriasis, blistering skin disease, uterine fibroid, infertility, migraine, hypertension, cancer), assert a correspondence, and stop; several close by proposing biomarker work as future research. Two studies bear empirically on the construct and both run against it. A 2024 emailed vignette survey of 141 experienced practitioners found a significant lack of consensus on diagnosis, on pathophysiology and on treatment across five scenarios, and concluded that these constructs do not uniformly determine prescriptions or individualisation (PMID 39183608). A 2019 reliability study nested in an RCT found chance-corrected agreement between four Ayurvedic experts of kappa 0 to 0.4 on core components including prakriti and agni, despite 95 percent agreement on the consented final diagnosis (PMID 30653338).\n\nTHE ATTEMPTS TO OPERATIONALISE IT, NAMED RATHER THAN DISMISSED. The gathered record's verdict of 'no validated operational definition' passed over the efforts that tried to build one, which is not an honest way to report a null. The named efforts, as far as these searches reach: AyuSoft, the C-DAC Pune decision-support software, whose prakriti module was measured against two independent physicians at ICC 0.72 for vata, 0.58 for pitta and 0.44 for kapha (PMID 33750638); the wider body of prakriti assessment tools, audited in a 2025 scoping review of 32 studies that found 3 of 16 questionnaires both reliable and valid, 3 of 5 algorithmic methods using validated machine-learning models, and 1 of 11 devices validated with reproducible data, and that names 'finding the ground truth in a robust manner' as the standing obstacle (PMID 40582042); and Ayurvedic health informatics generally, including 'development of Traditional Medicine databases for decision system support' (PMID 26160148). Two things must be said about this list, and the second is the more important. First, every one of these operationalises a samprapti INPUT, chiefly prakriti, and none of them encodes samprapti or samprapti ghataka; the searches run for this record, which are logged in gatheringNotes, returned no indexed study evaluating a computational encoding of samprapti itself, and 'AyuSoft' returns 7 records of which all 7 concern prakriti. Second, the audits of the inputs are themselves unfavourable, and the 2025 review's ground-truth problem is the one that bites hardest: a tool can only be validated against a reference standard, and for these constructs the reference standard is expert judgement of the kind measured at kappa 0 to 0.4.\n\nWHAT FOLLOWS. A reader should treat samprapti as a structured clinical narrative and a teaching framework. Its reproducibility has been tested indirectly, through the components a samprapti is assembled from, and the results were poor; whether a samprapti statement itself is reproducible between two clinicians was not addressed by any study these searches found. It is not a validated pathophysiological model. This record does not assert that no validation exists anywhere, only that the searches it names did not find one, and notKnown states the bound on each of those searches.","summary":"Samprapti is the Ayurvedic term for the account of how a disease came about. This record keeps apart three objects that the word is used for, because the gathered version ran them together and that conflation was its central defect.\n\n(1) Charaka's samprapti. Nidana Sthana 1 treats it as one of five things from which a disease is ascertained, alongside cause, premonitory signs, manifest signs and response to a trial of contrary measures (Ni. 1/6). It gives jati, birth, and agati, coming-on, as words of the same import (Ni. 1/11). It divides samprapti by five analytic heads (Ni. 1/12) and then defines each of the five in the lines that follow (Ni. 1/12.1 to 12.5): sankhya, number, as in eight kinds of fever; pradhanya, which dosha is the stronger or the strongest; vidhi, class, by two, three or four kinds; vikalpa, the measure in which doshas standing in combination have been excited; and balakala, strength-and-time, read off season, day, night and the hours of eating. That definitional run is the closest thing in the samhita to an operational definition of samprapti, and what it operationalises is how to subdivide a pathogenesis once stated, not how to establish one.\n\n(2) The worked narrative. Charaka's fever chapter runs one such sequence end to end: excited vata enters the stomach, mingles with the heat of the digestive fire, overtakes the food-juice, obstructs the ducts bearing food-juice and sweat, displaces the digestive fire so that its heat spreads through the body, and fever is generated. Later samprapti narratives follow this shape.\n\n(3) Samprapti ghataka and samprapti vighatana. Modern Ayurvedic teaching breaks samprapti into a checklist of ten to twelve 'components' (dosha, dushya, agni, ama, srotas, srotodushti-prakara, udbhava-sthana, sanchara-sthana, adhishthana, roga-marga, sadhya-asadhyata) and names the aim of treatment samprapti vighatana, breaking the chain. Object (3) is what contemporary clinicians and papers actually operate; the case reports at modern[5] and modern[6] are written in its vocabulary. It is not object (1). No classical verse enumerating the ghataka list was found by the searches this record names in gatheringNotes, sources do not agree on its membership, and it does not acquire Charaka's authority by sharing his word. Charaka gives five analytic heads; the ghataka list is a later teaching compilation.\n\nAcross all three, samprapti is reconstructed by the clinician from history and examination rather than measured. None of the sources retrieved for this record states an observation that would confirm or refute a proposed samprapti. That is a statement about a bounded search, not about the world; notKnown gives the bound.","contested":[{"question":"Does samprapti actually drive individualised Ayurvedic prescribing, as the curriculum claims?","positions":["The standard Ayurvedic teaching position: diagnosis and treatment are individualised through samprapti, agni assessment and dosha analysis, and this is what distinguishes Ayurvedic from protocol-based practice.","The empirical finding of PMID 39183608: across 141 practitioners and five case scenarios the constructs did not determine prescriptions or individualisation uniformly, and the authors explicitly raise whether this reflects an inherently weak theoretical framework."]},{"question":"Are the 'samprapti ghataka' a classical list or a modern teaching device?","positions":["Common modern textbook and journal presentation treats the ghataka list (dosha, dushya, agni, ama, srotas, srotodushti prakara, udbhava sthana, sanchara sthana, adhishthana, roga marga, sadhya-asadhyata) as the standard anatomy of samprapti.","Charaka's own text gives only the five analytic heads (sankhya, pradhanya, vidhi, vikalpa, bala-kala), quoted at classical[2] and each defined at classical[3]. No classical verse enumerating the ghataka list was found by the searches named in gatheringNotes; it appears to be a later pedagogical compilation, sources do not agree on its exact membership, and no retrieved source names its author or its date. This position is unchanged from the gathered record. It is restated here because it is the entry that refuted the record's own evidenceState, and the evidenceState was rewritten to agree with it rather than this entry being softened to agree with the evidenceState."]},{"question":"Verse numbering of the key Charaka passages.","positions":["The Trikamji Sanskrit, verified at carakasamhitaonline on 2026-10-06, numbers the nidana-panchaka line Ni. 1/6, the jati/agati synonym line Ni. 1/11, the list of analytic heads Ni. 1/12, and the five definitions Ni. 1/12.1 to 12.5.","Kaviratna's public-domain translation numbers the same passages 3, 5, 6 and 7 to 10, and prints each number AFTER its aphorism. His partition is not Trikamji's: his aphorism 3 spans Trikamji 1/5 to 1/9, and he breaks pradhanya across his 7 and 8 where Trikamji has one sub-part. So his numbers do not stand at a fixed offset and must never be converted arithmetically to a Trikamji number. Any citation of these verses must state which system is meant.","The gathered record's own numbers were right but their source was vague: it said 'numbered 1.6 / 1.11 / 1.12 in modern editions' without naming an edition.

The six is an artefact of his English splitting one compound, and this record's components list has always had five. See classical[3] translatorVoice.","A third enumeration, which is in the critic's finding itself and is supported by neither of the above: 'sankhya, vikalpa, pradhanya, bala, kala', which splits balakala into two AND omits vidhi.

No retrieved source gives a disconfirming criterion, and Charaka's definitional run at Ni. 1/12.1 to 12.5, newly added as classical[3], does not supply one either: it tells a physician how to subdivide a pathogenesis, not how to test one. This is the central epistemic gap in the record and retrieving the classical material the critic asked for made it sharper rather than closing it.","The textual locus of the universally quoted maxim that treatment is nothing but nidana-parivarjana and samprapti-vighatana.

Reviews retrieved for this record repeatedly propose biomarkers as future work; none of those retrieved reports a validated one.","How samprapti should be reconciled with, or distinguished from, biomedical pathophysiology when the two conflict for the same patient. The sources retrieved assert compatibility rather than test it.","THE COMMENTARIAL LAYER, scoped out explicitly rather than paraphrased. This record cites no commentary on samprapti and therefore says nothing about how the construct was read after Charaka. Specifically absent: Chakrapanidatta's Ayurveda Dipika on Charaka Nidana 1; Madhava Nidana chapter 1 with the Madhukosha of Vijayarakshita and Shrikanthadatta; and Vagbhata's variant at Ashtanga Hridaya Nidana 1. What was tried, so a later worker need not repeat it: GRETIL's Carakasamhita-with-Ayurvedadipika file (caraka_u.htm, retrieved 2026-10-06) does carry the commentary, but its Nidanasthana coverage is chapter 7 only, so Chakrapani on Nidana 1 is not in it. No public-domain English of the Ayurveda Dipika, the Madhukosha or the Ashtanga Hridaya was found; the standard English Madhava Nidana (Murthy, Motilal Banarsidass) is in copyright. By this project's rule of no quote, no citation, the gap is stated here rather than filled with paraphrase. The consequence for the record's claims should be stated too: because the commentarial layer is absent, this record cannot say where between Charaka and the modern manuals the ghataka checklist arose, and it does not try to.","THE ORIGIN OF SAMPRAPTI GHATAKA. No classical locus for the ten-to-twelve-item checklist was found, and beyond that, no retrieved source names its author, its date, or the text that first prints it, and retrieved sources do not agree on its membership or even its length. The record carries it in components because it is what modern clinical writing operates, labelled as a teaching construct. Who built it, when, and from what, is unknown to this record. Bound: the searches logged in gatheringNotes, which were run against PubMed and against the public-domain Charaka and Sushruta translations, and not against the MD(Ay) thesis literature or Indian-language teaching manuals where the critic suggests it originates and where it is most likely to be documented.","WHETHER SAMPRAPTI ITSELF HAS BEEN COMPUTATIONALLY ENCODED OR EVALUATED. The searches run for this record found no indexed study evaluating a decision-support encoding, ontology or knowledge graph of samprapti or of samprapti ghataka. What they did find is named in evidenceState and cited at modern[7] to modern[9], and in every case the construct operationalised is an input, chiefly prakriti, not samprapti. The bound, stated precisely because the critic is right that a null needs one: PubMed 'AyuSoft' returns 7 records (2026-10-06) and all 7 concern prakriti; 'Ayurveda knowledge graph' returns 3, none on samprapti; 'Ayurveda semantic web' returns 0; 'Ayurveda ontology' returns 38, of which the ones screened are dominated by gene-ontology and network-pharmacology work that uses 'ontology' in an unrelated sense. PubMed is the wrong index for this question: decision-support software of this kind is documented in IEEE and conference venues and in institutional reports, which were NOT searched. A reader should treat this as 'not found in the medical literature index searched', not as 'does not exist'.","WHETHER CHARAKA'S FIVE ANALYTIC HEADS WERE EVER USED AS THE MODERN GHATAKA ARE. classical[3] establishes that Charaka defines the five heads. Nothing retrieved here shows them being applied, in any period, to work up an individual patient, and the modern clinical reports retrieved use the ghataka vocabulary rather than the five heads.

Charaka Su.16.20 asserts that doshas subdued by fasting and digestives may recur while those evacuated by shodhana do not, and Su.16.21 justifies it by a simile about tree roots rather than by any observation of relapse. That claim is a relapse-rate claim and would be straightforward to examine with a follow-up period, yet none of the comparative studies located includes one. The empirical literature located consists of very small unblinded comparisons, ten to twenty patients per arm, in which shodhana arms are additionally given shamana drugs so the two cannot be separated, with outcomes on symptom grades this record could not find validated. A 2026 registered protocol from an Ayurvedic university states plainly that the effect of seasonal purification on healthy individuals remains a gray area, which is a fair summary.\n\nCORRECTED 2026-10-06, on criticFindings.overclaimed item 2. The 2026-09-19 version of this paragraph said there is no operational definition of when a patient is shodhana-eligible versus shamana-eligible. That conflated 'not validated' with 'not stated', and it was contradicted by this record's own citations. The criteria are stated, enumerated and operational. Charaka Siddhi Sthana 2 is built as a pravritti and nivritti list for each of the five procedures in turn, opening with avamyas tavat, 'those not to be given emesis are', and closing each pair with sesas tu vamyah, 'the rest are fit', so eligibility is defined by exclusion. Charaka Su.16.13-16, a passage this record already quoted but had mis-addressed, lists the signs of bahudosha and concludes that for such a patient purification is beneficial, upward or downward, yathadosam yathabalam. Ashtanga Hridaya Su.14.12-14 allocates patients between samshodhana, pachana-dipana and restraint of hunger and thirst by ordinal tiers of body bulk and strength. Sushruta's Sutrasthana gives contraindication lists for alkali, cautery and bloodletting, and at Chapter XII makes the physician's checklist explicit: the seat of the disease, the patient's strength, the marmas, the nature of the malady and the season. And the categories are not merely historical: a registered 2026 trial screens its participants for being vamanarha and virechanarha and for madhyama koshtha by questionnaire.\n\nWhat is actually missing is narrower and worse. Not one term in any of those lists is given a measurable definition. Nothing in the retrieved passages says where atisthula begins, how durbala is distinguished from merely weak, or what instrument assesses koshtha; the 2026 protocol's koshtha questionnaire is unnamed and no validation of it is cited. No source located reports agreement between physicians applying these lists to the same patient. The lists also do not agree with each other: Siddhi Sthana 2.8 contraindicates emesis for the atisthula while Ashtanga Hridaya 14.12 directs samshodhana at those in whom sthaulya is in excess, and no retrieved source reconciles them.\n\nCORRECTED 2026-10-06, on criticFindings.overclaimed item 1. The 2026-09-19 version said no classical text gives numeric thresholds for any of the variables the choice turns on. That was an unbounded negative about the whole corpus generalised from a reading that had never opened Siddhi Sthana, and it was false against a volume already on disk. Charaka Si.1.13-15 grades emesis and purgation by counted bouts, four, six and eight for emesis and ten, twenty and thirty for purgation, by prastha multiples, and by terminal product, excluding the first two or three faecal bouts from the count. Si.1.25 prescribes anuvasana basti in integers keyed to the dominant dosha, one or three for kapha, five or seven for pitta, nine or eleven for vata, in odd numbers. Sushruta Ci.XXXV grades basti pipe length and asthapana volume by the patient's age, two, four, eight and twelve prasritas, and its memorable verse ties the increase to age, strength and bodily capacity. These are real numbers. Two things keep them from being thresholds for the choice this record is about. They are dose and adequacy rules inside an already chosen course of treatment, not rules for choosing between shodhana and shamana. And the prasrita is defined in the main text as what the patient's own palms will hold, so even the measured unit is indexed to the individual body rather than being an absolute volume.\n\nBeyond that, there is no biomarker of adequate purification reported in anything located, and no reliability data on either the clinical completion signs or the counted and measured ones. The doctrine is also not stable across the classical corpus: Charaka makes shodhana and shamana the primary fork, Sushruta makes them two of four, and Vagbhata subordinates both to langhana, this last now quoted in the Sanskrit at AH Su.14.4 rather than reported from a web summary. A reference work should record the distinction as a well-attested organising scheme of the tradition, with eligibility and dosing rules that are detailed, quantified in places, mutually inconsistent in places, and unvalidated throughout, whose central empirical claim is untested. Every negative in this paragraph is a statement about the searches recorded in gatheringNotes and not about the field.","summary":"Shodhana and shamana name the two basic ways Ayurveda claims a disturbed dosha can be dealt with: expelled from the body by an eliminative procedure, or brought back to normal state in situ by diet, drug, fasting and regimen. The doctrine attaches a specific and falsifiable-sounding claim to the distinction: doshas subdued by fasting and digestive measures may be aggravated again, whereas doshas evacuated by purification do not recur. Sushruta adds diet and conduct as two further co-equal factors alongside the pair, and Vagbhata reorganises the whole scheme by making shodhana a subtype of langhana rather than its opposite. The choice between the two in any given case is said to turn on the strength of the patient, the strength and stage of the dosha, the season, and the presence or absence of ama. Quantified rules do exist in the passages retrieved for this record, and they sit at the level of dose and of adequacy rather than at the level of the choice itself: Charaka's Siddhi Sthana grades emesis and purgation by counted bouts and by measured volume, prescribes anuvasana basti in counts keyed to which dosha is dominant, and Sushruta grades basti pipe dimensions and asthapana volumes by the patient's age. What no retrieved passage supplies is a measurable definition of the terms the choice turns on, which is a narrower and different point from the one the 2026-09-19 version of this record made.","contested":[{"question":"Is shamana genuinely less durable than shodhana?","positions":["Charaka Su.16.20 asserts it directly and it is repeated throughout the later tradition and modern Ayurvedic writing as settled.

Vagbhata's definition of shamana at AH Su.14.6, now quoted in the Sanskrit, cuts across the question rather than answering it: shamana is defined there as that which neither purifies the doshas nor stirs the settled ones but equalises the uneven (na sodhayati yad dosan saman nodirayaty api| samikaroti visaman).

Charaka's term is ati-sthula and Vagbhata's is sthaulya-adhika, and Charaka's exclusion is specific to vamana while Vagbhata's indication is for samshodhana generally, so a reading on which Charaka excludes only the extreme case from emesis while Vagbhata addresses the merely excessive case with purification in general would dissolve it.

The 2026-09-19 version said no criteria determine shodhana eligibility expressed as anything measurable, and that 'strength of the patient and strength of the dosha' has no instrument. The first half was wrong and has gone: the criteria exist and are enumerated at Ca.Si.2.8, 2.10 and 2.13, Ca.Su.16.13-16, AH.Su.14.12-14 and in Sushruta's Sutrasthana XI, XII and XIV, all now cited and quoted in this record. The second half survives and is the real gap. No retrieved passage gives a measurable definition of any term in those lists: not atisthula, not durbala, not bahudosha, not samvrtakostha, not the bala the Sushruta memorable verse at Ci.XXXV makes the dose depend on.

The 2026-09-19 version asked whether any marker of adequate purification exists 'other than the clinical signs listed in Ch.Su.16.17-19', which was wrong because this record had never opened Siddhi Sthana. Charaka Si.1.13-15 gives three further completion criteria: counted bouts, a measured volume in prastha multiples, and a terminal product, pitta for emesis and kapha for purgation. What remains not known is whether any of the four criteria predicts any outcome, whether they agree with each other in a given patient, whether the clinical signs are reliably scored between observers, and whether any physiological or biochemical marker exists; PMID 42748372 proposes to measure three serum markers but has reported no results.","Whether the benefit seen in combined shodhana-plus-shamana arms comes from the shodhana, the shamana, the dietary regimen, the samsarjana krama, or the extended practitioner contact.

That version said the marker was OCR-damaged and was not independently confirmed; in BIUSante_47357 the digits are present, printing as 'included under Langhana^1 8'. They are not reliably resolvable: the marker follows a run of Kaviratna numbers ending at his 16 for the stambhana qualities, so it is either 17, which would hold the two-behind offset seen earlier in this chapter, or 18, which would not. No Kaviratna number is asserted.

Note that the Sanskrit counts seven heads which expand to ten when the fourfold samshuddhi is enumerated, which is how Kaviratna's English reaches ten. NUMBERING. Two numbering systems are recorded separately and neither is presented as verifying the other. Kaviratna prints his own aphorism number AFTER the aphorism in his English text; the standard number is the Trikamji-based numbering of the verse-numbered Sanskrit at carakasamhitaonline.com, whose English is in copyright and is not quoted anywhere in this record. Attaching a third-party edition's number to Kaviratna's English and calling it 'confirmed', which the 2026-09-19 version of this record did, is an edition splice: a reader checking the citation in the quoted edition will not find that number on the page.

It is Bhishagratna's own footnote, marked with a dagger keyed to this sentence and printed at the foot of page 11, reading in part 'Cleansing (Samshodhanam) is of two kinds, viz. External and Internal. External purification consists in employing such measures as surgical operations, cauterisation of the affected part or organ, external use of alkaline preparations and medicated plasters, the internal one including such measures as exhibition of purgatives and emetics, application of intestinal enemas (Asthapanam) and blood-letting.' That is a translator's gloss and is recorded here as his, not as Sushruta's.

The 2026-09-19 version carried this chapter from 'a retrieved chapter summary' whose verse attributions it admitted were 'reported rather than independently confirmed', while two contested items in this record leaned on those attributions to settle textual disputes. Every attribution it reported is now confirmed from the Sanskrit, so nothing had to be withdrawn, but it was being asserted on inadequate grounds until this revision. CHAPTER NUMBER confirmed independently of any summary: the GRETIL file is the Sutrasthana, whose own closing verse at 1.48 reads sutra-sthanam ime 'dhyayas trimsac charIram ucyate, thirty chapters; this is the fourteenth chapter marker in the file, and the variant-reading lines inside this block are tagged 14.14, 14.19, 14.23, 14.26, 14.29, 14.30, 14.31, 14.32, 14.34 and 14.35, which fixes the chapter number from inside the text. WHAT THE VERSES SAY, as this record reads the Sanskrit: 14.1, because the thing to be treated is two-fold the treatment is held to be two-fold, one santarpana and the second apatarpana; 14.2, brimhana and langhana are given as their synonyms, brimhana being for bulk and langhana for lightness; 14.3, snehana, rukshana, svedana and stambhana are also named here, so Vagbhata does not drop the six but subsumes them; 14.4, these too do not exceed the two-fold, and there too langhana is two-fold, shodhana and shamana (sodhanam samanam ceti dvi-dha tatrapi langhanam); 14.5, that which drives the doshas outward is shodhana and it is five-fold, niruha, vamana, kaya-reka, shiro-reka and asra-visruti, bloodletting named among the five; 14.6, that which neither purifies the doshas nor stirs the settled ones but equalises the uneven is shamana, and it is seven-fold; 14.7, pachana, dipana, kshut, trut, vyayama, atapa, maruta. This is a materially different architecture from Charaka's, in which shodhana and shamana are the primary fork. The verse 1 and verse 4 attributions the earlier version reported, the count of five with bloodletting among them, and the count of seven with exactly that membership, are all confirmed.

PubMed E-utilities on 2026-10-06 returned 19 records for 'srotas AND ayurveda' and 21 for 'srotas' alone, 5 for 'srotodushti', and 0 each for 'srotorodha' and 'dosha dushya sammurchana'; the query translations and PMIDs are logged so these can be re-run. Screened by title and type, the srotas set is mostly single-patient case reports, small uncontrolled studies of herbs or procedures indexed under a channel heading, and narrative reviews that restate the classical account in modern vocabulary. DHARA, which indexes the Indian Ayurveda journals PubMed does not, returned 23 records for 'srotas', 6 for 'srotodushti' and 1 for 'srotorodha'; the srotodushti set was screened in full and the srotas set only on its first page. The AYUSH Research Portal, the largest relevant index, failed server-side on every attempt and has not been searched, which is the largest boundary on every negative statement here. Within what was searched: one study operationalises a channel-level construct, the 2026 Medovaha Srotas Dushti questionnaire (PMID 42181430), which agreed with metabolic-syndrome criteria at kappa 0.84 in 90 participants but measures one channel's vitiation, not any of the four srotodushti modes, and reports agreement with a biomedical criterion rather than between clinicians. No record located operationalises atipravritti, sanga, siragranthi or vimargagamana as a measurable variable, and none located reports inter-rater reliability for assigning a patient to a channel. The hospital survey that counted purishavaha srotodushti in 42% of 235 patients (PMID 22529647) used unstated assignment criteria. The one data-collecting study that tests the framework's clinical use, the 2024 case-vignette survey of 141 experienced practitioners (PMID 39183608), found significant disagreement about the pathophysiology to assign to the same case. Outside srotas, the Ayurgenomics work on prakriti (PMIDs 18782426, 26511157) shows that a classical construct can be put against molecular measures; nothing comparable was located for srotas, and the record's negative is bounded to srotas accordingly. As of this record, the srotas system rests on classical exegesis and clinical convention, with one recent channel-level instrument whose independent validation is pending.","summary":"Srotas are the transport channels of the body in Ayurvedic physiology: the passages through which the dhatus (tissue substrates), the malas (wastes) and the doshas move and in which the transformation of one dhatu into the next is said to occur. Charaka's Vimana Sthana 5 says the body's phenomena are all modifications of channels (Ca.Vi.5/3), rejects the view that a person is nothing but channels (5/4), records that some hold them innumerable and others countable (5/5), and then enumerates thirteen gross channels 'yathasthulam', as a teaching subset (5/6-7). For each it names a moola of two seats (5/8: for example hridaya and mahasrotas for pranavaha; vrikka and vapavahana for medovaha). For six of the thirteen (prana, udaka, anna, mutra, purisha, sweda) it gives a channel-specific sign-set in the same passage; for the seven dhatuvaha channels it refers the reader to the dhatu-vitiation signs of Sutra Sthana 28 rather than giving separate channel signs. Thirteen verses (5/10-22) list the dietary and behavioural causes that vitiate each channel, with a general rule at 5/23. Vitiation (srotodushti) is characterised by four signs (5/24): excessive flow, obstruction, nodular swellings of the vessels, and diversion of contents into a wrong path. The text's universal statement is the converse one at 5/7: a body whose channels are in their natural state is not afflicted by disorders. The teaching position that every disease involves at least one of the four derangements is a later generalisation of 5/24, and this record cites no classical sentence that states it in that form. Sushruta's account differs on the count (eleven channels taken in pairs), on the roots assigned (kati and vrikka for medovaha), on whether srotas is distinct from sira and dhamani (Su.Sha.9 says it is; Chakrapani says Charaka intends no such distinction), and Sushruta Sutra 24/9 uses a three-fold scheme (sanga, atipravritti, ayathapravritti) for disorders of the mala receptacles where Charaka's srotas scheme has four.","contested":[{"question":"How many srotas are there, and what are their roots?","positions":["Charaka Vimana 5/7 enumerates thirteen, taken singly, including asthivaha, majjavaha and swedavaha, and gives no artavavaha channel; 5/29 confirms 'trayodashanam mulani srotasam'.

CORRECTED on revision: for medovaha, Charaka's own text gives vrikka and vapavahana (Ca.Vi.5/8, 'medovahanam srotasam vrikkau mulam vapavahanam ca'), not his commentators; Sushruta gives kati and vrikka (Su.Sha.9/12, Bhishagratna: 'the region of the Kati (waist) and the Vrikkas (kidneys)'); and Chakrapani on 5/8 quotes the Sushruta reading and declines to resolve the difference. Other differences: Charaka's rasavaha root is hridaya and ten dhamanis, Sushruta's is the heart and the rasa-carrying dhamanis; Charaka's shukravaha root is vrishana and shepha, Sushruta's is the breasts and the testes."]},{"question":"Is srotas the same category as sira and dhamani?","positions":["Charaka Vimana 5/9 lists srotamsi, sirah and dhamanyah among thirteen names for the same spaces of the body's dhatus, treating them as synonyms.

Sushruta's separate counts are the structural evidence for his position: seven hundred siras (Sha.7), twenty-four dhamanis rooted at the navel (Sha.9/2-3), and eleven paired srotas (Sha.9/12). Charaka gives no separate counts and uses 'dasha dhamanyah' only as the root of rasavaha. Whether this is two anatomies or one anatomy described at two levels of resolution is not decidable from the texts."]},{"question":"What does 'kha' or channel space denote physically?","positions":["A gross tubular structure, so that srotas maps onto vessels, ducts and hollow viscera.","A functional unit comprising the channel wall, the dhatvagni situated in it and the dhatu flowing through it, so that 'channel' is not primarily anatomical at all.","An irreducibly subtle category: Charaka's own words are 'lakshya-alakshyanam' (visible and invisible, 5/9) and one school holds them 'aparisankhyeyani' (uncountable, 5/5), which some argue makes any one-to-one anatomical mapping a category error. Bhishagratna's bracketed identifications in Su.Sha.9 (bronchi, pulmonary arteries, oesophagus, capillaries) are the earliest such mapping in the record and are the translator's, not the text's."]},{"question":"Is the four-mode srotodushti scheme exhaustive and mutually exclusive?","positions":["The standard teaching position is that one or more of the four is present in every disease, which makes the scheme universal. The record locates no classical sentence stating this in that form; Ca.Vi.5/24 calls the four 'dushti-lakshanam', and the universal statement in the chapter is the converse at 5/7, that a body with channels in their natural state is not afflicted.","The universality claim is untestable as stated: no paper located defines a case in which none of the four applies, so the scheme cannot be falsified by any clinical observation reported in the literature searched.","ADDED on revision. Sushruta uses a different and three-fold scheme where Charaka uses four. Su.Su.24/9 classifies disorders of the mala receptacles as sanga, atipravritti or ayathapravritti, and disorders of the sense-organ seats as apravritti or ayathapravritti. It shares sanga and atipravritti with Ca.Vi.5/24, has ayathapravritti where Charaka has vimargagamana, and has no counterpart to siragranthi. It is a scheme for receptacles rather than for srotas by name, so it does not contradict Charaka directly, but it shows that the four-fold list was not the only classical way of carving up derangement of flow, and the later literature that treats the four as canonical does not usually cite it.","ADDED on revision. The one instrument located (PMID 42181430) operationalises medovaha srotodushti as a whole and does not distinguish the four modes, so the question whether the modes are separable in patients has not been put to data."]}],"notKnown":["No operational definition of any of the four srotodushti modes was located: no published threshold, instrument or protocol by which two clinicians would independently decide that a given patient has sanga rather than atipravritti.

Bounded by the searches in searchRecord; the AYUSH Research Portal and the thesis literature were not searched.","Inter-rater reliability for assigning a patient to an affected channel was not located in any record searched. The kappa of 0.84 reported for the medovaha questionnaire is agreement with a biomedical case definition, not between raters. The reliability figures that do exist in Ayurveda (kappa near 0.07 for pulse, 0.17 for tongue) concern other diagnostic acts entirely and cannot be transferred to channel assignment.","Whether any proposed physiological correlate of a named channel holds. Within the material located, one correlate has been tested against an independent measure: medovaha dushti, as scored by a questionnaire, against metabolic-syndrome criteria in 90 people, cross-sectionally and without independent replication. The mappings asserted for rasavaha (lymphatic or plasma compartment), majjavaha (marrow or nervous tissue) and pranavaha (bronchi) were found only as argument, not as tests.","Whether the count is thirteen, twenty-two, or some other number is not resolvable from the texts, which say in the same breath that the channels are innumerable.","It is not known whether channel-directed reasoning changes treatment outcome.

This revision could not reproduce that check: the ICD-11 API (id.who.int) requires an OAuth bearer token and returned 401, and the public browser at icd.who.int is a JavaScript application whose search endpoints return the shell page, so the chapter text was not retrievable by HTTP on 2026-10-06. The critic's negative is therefore recorded as reported and not as verified here. What is confirmed independently is only the module's existence; its 529 categories and the 1,941 NAMASTE morbidity codes mapped to it are figures from the record's original gathering and were not re-checked.","The relationship between srotas and agni is asserted (dhatvagni is said to be situated in the channel) but the texts do not state whether channel defect causes agni defect, follows from it, or is the same event described twice.","ADDED on revision. Whether Kaviratna's English omission of the medovaha and asthivaha root clauses in Vimana 5/8, present in both scans consulted, reflects his Bengali source text or a loss in printing.

It is a normative definition, and the chapters that state it give no measurement procedure, threshold or instrument for any of its seven clauses. The nearest classical material to an assessment procedure, Charaka's tenfold examination of the patient (Vi. 8.94) and his fourfold agni classification (Vi. 6.12), is now cited; both name heads of examination and behavioural types without a scoring rule, and the tenfold examination's own stated purpose is to gauge strength for dosing, not to classify a person as healthy. On the modern side, this record now separates three things that an earlier draft ran together. First, instruments: questionnaire operationalisations exist for the agni clause (PMIDs 26283805, 27381899, 41774580) and for dosha constitution (33750638, 34548242), and one composite Ayurveda-principle-based health scale was located (Swasthya Assessment Scale, 37347084, whose authors state that nothing validated preceded it). Each reports internal consistency or observer agreement; one agni tool reports an association with serum lipids (27381899); none located here reports criterion validation against a health outcome, test-retest stability of the composite, or replication. In the newest agni scale the samagni subscale was the one that failed the reliability threshold (41774580). Second, reliability of clinical judgement: three independent studies measure it. Among four experts rating 30 knee-osteoarthritis patients, chance-corrected agreement on prakriti and agni was fair to poor (kappa 0 to 0.4) despite 95 percent consensus on the final diagnosis (30653338); among fifteen doctors examining twenty healthy volunteers, average pairwise kappa was 0.07 for pulse, 0.17 for tongue and 0.28 for prakriti (24191170); software-versus-clinician agreement on prakriti was ICC 0.72 for vata, 0.58 for pitta and 0.44 for kapha (33750638). These studies rate prakriti, which is constitution, not the current dosha state (vikriti) that the samadosha clause concerns, and only one of them (30653338) rates agni; none rates dhatu or mala state. So the honest statement is narrower than 'the first three clauses are not reproducibly ascertainable': the one clause for which a chance-corrected inter-rater figure was located, agni, measured poorly in that one small study, and the examination methods used to reach constitutional judgements measure poorly in two others. Third, validity: no study located in the searches recorded in gatheringNotes tests whether people classified swastha differ from the merely asymptomatic, whether baseline swastha status predicts anything, or whether the Ayurvedic and WHO 1948 classifications agree on the same individuals; AYU and several Indian journals are incompletely indexed, so absence from these searches is not absence from the literature. The frequently repeated claim that Sushruta's definition anticipated WHO 1948 is a modern interpretive comparison, not a finding. The position, then, is that the definition is philosophically clear and clinically unoperationalised in the classical texts; that modern instruments operationalise two of its clauses as questionnaire categories with internal consistency but, in what was located here, without criterion validation; and that the experts who apply the definition in practice agree on the final label while disagreeing on the constitutional components that are supposed to generate it.","summary":"Ayurveda defines health (swasthya; the healthy person is swastha) not as absence of disease but as a stated list of simultaneous equilibria. The locus classicus is the verse of Sushruta Samhita Sutrasthana 15 beginning samadoshah samagnishcha (numbered 15.41 in the Sanskrit presentations retrieved for this record and 15.48 in at least one Chaukhambha edition; see the citation entry), which requires balanced doshas, balanced agni (digestive and metabolic fire), balanced formation and function of the dhatus (tissues) and malas (excreta), together with a pleasant or clear state of atman, indriyas and manas (self, senses and mind). The verse immediately preceding it (15.40) states the physician's two-armed duty, preservation in the well and correction in the sick. Charaka states the same aim differently: the purpose of the science is dhatusamya, the restoration and maintenance of equilibrium of the body's constituents (Sutrasthana 1.53), and its twofold objective is preserving the health of the healthy and relieving the disorder of the diseased (Sutrasthana 30.26). Vagbhata compresses it further to dosha equilibrium alone (Ashtanga Hridaya Sutrasthana 1.20). The definition is constitutive rather than diagnostic: it names the conditions that must hold, and the chapters that carry it supply no thresholds or instruments for deciding whether they hold in a given person. The nearest classical material to an assessment procedure sits elsewhere, in Charaka's tenfold examination of the patient (Vimanasthana 8.94) and his fourfold classification of agni (Vimanasthana 6.12), neither of which gives a measurement rule either. Modern writing frequently contrasts the clause about mind, senses and self with the WHO 1948 definition of health as complete physical, mental and social well-being; that comparison is an interpretive move by modern authors, not something the classical text makes.","contested":[{"question":"What exactly does the mental clause, prasanna atmendriya manah, require?","positions":["A subjective state of contentment or pleasantness, making swasthya a wellbeing construct comparable to modern subjective wellbeing measures","A functional statement that the self, senses and mind are performing their operations without obstruction, closer to unimpaired sensory and cognitive function than to reported happiness","A soteriological clause about the self being settled in itself (the folk etymology swa-stha, 'established in one's own self'), which cannot be measured at all and belongs to Ayurveda's Samkhya frame rather than to its clinical frame"]},{"question":"Which classical definition is authoritative?","positions":["Sushruta 15.41 as the full definition, requiring seven simultaneous conditions including the mental one","Charaka's dhatusamya (Su. 1.53) as the operative definition, which is narrower and purely physiological","Vagbhata's formula rogastu doshavaishamyam doshasamyam arogata, which reduces health to dosha equilibrium alone and drops agni, dhatu, mala and mind"]},{"question":"Is swasthya a binary state or a continuum?","positions":["Binary: the definition lists conditions that either hold or do not, and a person is swastha or atura","Continuous: classical commentary on dosha vriddhi and kshaya describes degrees, and modern Ayurveda scale developers score health on ordinal bands, implying a gradient the source text does not authorise"]},{"question":"Does the definition anticipate the WHO 1948 definition?","positions":["Yes, commonly asserted in Ayurvedic literature because both go beyond absence of disease and both include a mental component","No: WHO adds a social dimension that Sushruta's list does not contain, and Sushruta adds physiological equilibria (agni, dhatu, mala) that WHO does not; the resemblance is partial and has never been tested empirically"]},{"question":"Can the clauses of the definition be ascertained reliably by trained clinicians, as opposed to by questionnaire?","positions":["No, or not yet: chance-corrected agreement among four experts on prakriti and agni was kappa 0 to 0.4 (PMID 30653338), and among fifteen doctors on pulse, tongue and prakriti it averaged 0.07, 0.17 and 0.28 (PMID 24191170); the examination methods that feed constitutional judgement are poorly reproducible between examiners.","Partly yes, by instrument rather than by examiner: structured questionnaires and software give consistent prakriti classifications (significant evidence against random rating in 24191170; ICC 0.44 to 0.72 against clinicians in 33750638) and agni questionnaires reach Cronbach's alpha above 0.87 on three of four states (26283805), so the construct is reproducible when the clinician is removed from the loop, at the cost of not knowing whether the questionnaire measures what the clinician was meant to judge.","The question is mis-posed for the composite: every reliability figure located concerns one clause or one examination technique; no study located here rates the seven-clause swastha judgement as a whole, so the composite's reliability is simply unmeasured (see notKnown)."]}],"notKnown":["What measured value of any biomarker corresponds to samagni, samadosha or sama dhatu-mala kriya.

Google Scholar, AYUSH Research Portal, DHARA and non-English literature were not searched, so these are counts for one database on one date and not claims about the world. Within that scope: no interrater reliability figure, no sensitivity or specificity against a reference standard, and no validated instrument for any dhatu kshaya or vriddhi judgement was located. On agreement in Ayurvedic assessment generally, the two measurements retrieved here point in different directions: Kurande et al. found average pairwise kappas of 0.07 (pulse), 0.17 (tongue) and 0.28 (prakriti) among fifteen doctors (PMID 24191170), while Rotti et al. found a kappa of 0.77 between physicians and a structured tool for prakriti in 3,416 subjects (PMID 25336848). Neither concerns kshaya or vriddhi, and they give no basis for predicting agreement on these sign-lists in either direction. On quantity, the record previously described the absence of a stated normal measure as a gap; Sushruta states it as doctrine (Su.Su.15.37: parimANaM na vidyate) and prescribes inference from health and from the signs in its place (15.38-40), so the model is non-quantitative by design, and the open question is whether any modern operationalisation has been attempted, not whether the texts omitted one. ICD-11 TM2 now assigns a code to every one of these patterns; in the project's enrichment data those codes carry names and index terms but no definitions, so they standardise the vocabulary without supplying criteria. The one trial that uses a dhatu kshaya as an enrolment category (PMID 24250128) reached its outcome measure by assuming rakta kshaya equals anaemia, which is the operationalisation that needed testing. The framework's standing on this record's evidence is as a structured clinical vocabulary with internal coherence, an explicit theory of why it cannot be quantified, and long use, not as a validated diagnostic system.","summary":"Ayurveda holds that health is a state in which the doshas, the seven dhatus and the malas are each present in their proper measure, and that disease arises when any of them increases (vriddhi) or decreases (kshaya) from that measure. The governing rule is the principle of samanya and vishesha: like increases like, unlike decreases it, so a deficient constituent is replenished by substances resembling it and an excessive one is reduced by substances unlike it (Charaka Sutrasthana 1.44-45 in standard numbering; Kaviratna prints 43-44). Sushruta Sutrasthana 15 is the primary locus: it lists the signs of decrease and of increase for each dosha, each tissue and each excretion, prescribes replenishing or reducing treatment accordingly, and closes with the obesity and emaciation (sthaulya and karshya) that follow from rasa going wrong in either direction. On the question of measurement the chapter takes an explicit doctrinal position rather than leaving a gap: because bodies differ and change from moment to moment, the quantity of the doshas, dhatus and malas cannot be laid down (15.37); their equilibrium can be known only through the presence of health (15.38); their disparity is inferred from the state of the senses and the signs (15.39); and the physician reduces or builds until the patient is free of disease, which is itself the mark of balance (15.40). The system is therefore a sign-based and inference-based clinical method by its own account, and it defines the balanced state positively as well as negatively (15.41). Charaka's Ashtauninditiya chapter (Sutrasthana 21) supplies the companion material on the over-nourished and under-nourished body, and Sutrasthana 22 defines the two therapeutic directions, langhana and brimhana, that the diagnosis leads to.","contested":[{"question":"Does rakta kshaya denote anaemia?","positions":["The equation is standard in modern Ayurvedic clinical research and is assumed outright in the one trial on the subject (PMID 24250128), which uses haemoglobin, serum iron, ferritin and TIBC as outcomes.","Sushruta's own sign-list for rakta kshaya is rough skin, craving for acid food and drink, longing for cool places and flabby veins - pallor is not among them, and the chapter's separate signs for pitta kshaya include dullness of complexion.

There are genuine molecular studies: genome-wide expression differences between extreme prakriti types (Prasher 2008), a permutation-tested genome-wide SNP study in 262 men selected from 3,416 (Govindaraj 2015), DNA-methylation differences in 147 men from that same 3,416-subject screen (Rotti 2015), an immunophenotyping pilot (Rotti 2014), a 16S gut-microbiome study (Chauhan 2018) with two later microbiome studies on different protocols, and a 38-subject plasma metabolomics study (Shirolkar 2018). What these establish is that groups sorted by Ayurvedic constitutional criteria are not molecularly identical. Three things about them need saying plainly. First, their internal confirmations are often the selection restated: Govindaraj's principal-component separation is computed on the 52 SNPs chosen because they differed between groups, and Shirolkar's 97.87% model recognition is a supervised fit on 38 samples. Second, extreme-phenotype designs that keep one subject in thirteen say nothing about the people screened out. Third, the EGLN1 altitude result (Aggarwal 2010), usually presented as a discovery reached through Ayurvedic typing, recovered a signal that Simonson et al. and Bigham et al. had already established in Tibetan and Andean genomics earlier the same year with no Ayurvedic input; prakriti correlated with something real, but did not find it. None of these studies claims, and none shows, a correspondence between vata, pitta or kapha and an identified physiological system, pathway or measurable quantity. On biomarkers, this record now has a named search to stand on: Venkatesh et al. 2025 (PubMed, Scopus and Cochrane to November 2024, 94 included studies) found 32 categories of measurable correlates studied against prakriti, only five of them with validated assessment tools, and no tool fully meeting their scale-development criteria. The theory itself, as opposed to prakriti classification, has attracted mostly narrative and analogical work, of which Hankey's coenzyme A argument (an editorial, not a study) is representative. The more serious problem sits upstream of all of it. Assignment of dosha state is the measurement on which every downstream study depends, and it measures badly. Chance-corrected inter-rater agreement between four trained Ayurvedic experts for prakriti and agni was between 0 and 0.4; software-versus-clinician agreement for kapha was ICC 0.44; two 2025 reviews of the instrument literature (Gupta et al., 32 studies; Venkatesh et al., 64 tools) found that fewer than a third of the tools had any validation and that two met most of the standard criteria. High percentage agreement on a final consensus diagnosis coexisting with poor kappa on its components suggests convergence on a shared conclusion by routes that are not the stated ones. Until the classification is reproducible, molecular differences between prakriti groups cannot be cleanly attributed to the constructs they are labelled with, and the genomic, epigenomic, microbiome and metabolomic findings should be read as findings about a phenotyping heuristic rather than as validation of tridosha. On the classical side, the revision found one further translator intrusion of the kind this project tracks: Sushruta's mula names the five pittas (21/10) but no kapha subtype (15/4, 21/14); the kapha names in Bhishagratna are his headings and footnotes.","summary":"Tridosha theory holds that three principles, vata (associated with movement and transport), pitta (with transformation, heat and digestion) and kapha (with cohesion, lubrication and structure), together constitute and regulate the body. In their normal state (prakrita) they sustain it; when deranged (vikrita) they produce disease. Each is assigned a set of physical qualities (guna) and anatomical seats, and each is said to be fivefold: Charaka names the five vatas (Ca. Su. 12.8), Sushruta names the five pittas as five agnis (Su. Su. 21/10) and locates five kaphas by seat without naming them (Su. Su. 21/14). Increase (vriddhi) and decrease (kshaya) of each dosha carry their own sign-lists (Su. Su. 15), and Sushruta's six-stage kriyakala (Su. Su. 21/18-37) is the classical account of how a deranged dosha moves from accumulation to manifest disease. The relative proportion of the three fixed at conception is prakriti, the individual constitution, which the texts hold to determine susceptibility, presentation and drug response. Sushruta calls the body tristhuna, three-pillared, and adds rakta (blood) as a fourth co-determinant; Charaka and Vagbhata keep the count at three. The theory functions in the classical texts as a general explanatory grammar covering physiology, pathogenesis, diagnosis, diet, season and therapeutics. It is not defined in the texts by reference to any observable substance, and the doshas are not the same as the humours of Greek medicine despite the standard English rendering of vata, pitta and kapha as wind, bile and phlegm.","contested":[{"question":"Are there three doshas or four factors?","positions":["Charaka and Vagbhata hold to three: vata, pitta and kapha","Sushruta explicitly adds rakta (blood) as a fourth co-determinant of the body's origin, maintenance and dissolution (Su.

Pittam therefore is called internal fire. Consequently, an enfeebled action of Pittam is remedied by the administration of drugs and substances which are akin to the elemental fire in their attributes, while an abnormal or excessive action (secretion) of Pittam is subdued by cooling measures as an over-kindled fire is subdued by moisture.

Even thus located, it keeps up the temperature in its other distant locations (skin, etc.) in virtue of its native heat-giving attribute. Hence this Pittam is called the Pachakagni (digestive fire or heat) in an animated organism. The Ranjakagni: The function of the Pittam, which has its seats in the liver and the spleen, consists in imparting its characteristic pigment (Ragakrit) to the lymph-chyle and is hence known as Ranjakagni (lit: dyeing fire or pigment bile.) The Sadhakagni: The Pittam seated in the heart is denominated as the Sadhakagni (performing or operating heat or fire) inasmuch as its action is to bring about the fruition or realisation of one's desires. The Alochakagni: The Pittam, which is located in the pupils of the eyes, is called the Alochakagni (the Pittam or fire of sight) as its office is to catch the image of any external object presented to the eyes. The Bhrajakagni: The Pittam, which has its seat in the skin, is called the Bhrajakagni (illuminating or irradiating heat) inasmuch as it absorbs the substances used in the shape of unguents, lubrications, etc. and irradiates the glow of one's natural complexion.","sanskrit":"तच्चादृष्टहेतुकेन विशेषेण पक्वामाशयमध्यस्थं पित्तं चतुर्विधमन्नपानं पचति, विवेचयति च दोषरसमूत्रपुरीषाणि; तत्रस्थमेव चात्मशक्त्या शेषाणां पित्तस्थानानां शरीरस्य चाग्निकर्मणाऽनुग्रहं करोति, तस्मिन् पित्ते पाचकोऽग्निरिति सञ्ज्ञा; यत्तु यकृत्प्लीह्नोः पित्तं तस्मिन् रञ्जकोऽग्निरिति सञ्ज्ञा, स रसस्य रागकृदुक्तः; यत् पित्तं हृदयस्थं तस्मिन् साधकोऽग्निरिति सञ्ज्ञा, सोऽभिप्रार्थितमनोरथसाधनकृदुक्तः; यद्दृष्ट्यां पित्तं तस्मिन्नालोचकोऽग्निरिति सञ्ज्ञा, स रूपग्रहणाऽधिकृतः; यत्तु त्वचि पित्तं तस्मिन् भ्राजकोऽग्निरिति सञ्ज्ञा, सोऽभ्यङ्गपरिषेकावगाहालेपनादीनां क्रियाद्रव्याणां पक्ता छायानां च प्रकाशकः ॥१०॥","translation":null,"translator":"Kaviraj Kunja Lal Bhishagratna (1907), public domain","licenceBasis":"cleared-translation","sourceUrl":"https://archive.org/stream/englishtranslati01susruoft/englishtranslati01susruoft_djvu.txt","checked":"checked against the source"},{"text":"Sushruta Samhita","sthana":"Sutrasthana","chapter":"21 (Vrana-prashna)","verse":"Su.

DHARA (Digital Helpline for Ayurveda Research Articles), the AYUSH Research Portal and the Clinical Trials Registry of India were not searched, and several Indian Ayurvedic journals are incompletely indexed in PubMed, so every statement of absence here means absent from PubMed as searched, not absent from the world. Within that scope: the classical text is unusually specific and the PubMed-indexed Ayurvedic evaluation of it is close to nil, while two of its thirteen physical claims coincide with mainstream clinical knowledge arrived at independently. Charaka's chapter is the most operationally detailed preventive doctrine in the corpus: thirteen named urges, a named syndrome for each, and a named treatment for each, with a mirror list of mental and moral urges to be restrained; Sushruta (Uttaratantra 55) names the same thirteen as types of udavarta and Vagbhata (Su 4) covers fourteen. Of the thirteen physical claims, two have modern counterparts. For stool: one small randomised crossover experiment in healthy adults (Klauser 1990) shows voluntary withholding alone slows colonic transit, and the Rome IV paediatric literature treats withholding as central to functional constipation, though as a perpetuating response rather than an origin. For urine: the paediatric urology literature (Koff 1998) associates dysfunctional elimination, which includes infrequent voiding, with breakthrough infection in children with reflux, and one cross-sectional adult survey (Reynolds 2019) associates limiting restroom use with urgency and incontinence; neither isolates postponement as a cause in a healthy tract. Sneeze suppression has a documented mechanism of harm through case reports of barotrauma, which is not Charaka's named syndrome. For the remaining ten urges (semen, flatus, vomiting, eructation, yawning, hunger, thirst, tears, sleep, post-exertional breathing) the searches found no PubMed-indexed study testing whether suppression causes the named disorders, and several of the claimed consequences (giddiness or delirium from suppressed weeping, gulma from suppressed breathing) have no obvious modern reading. The Ayurveda-specific items found in PubMed are one 1981 paper whose methods cannot be assessed from the available record and one 2019 protocol without results. No PubMed-indexed study of the doctrine as a whole, no instrument for measuring vega suppression, and no test of the vata-obstruction mechanism were found. The honest position is that two of the thirteen physical claims have independent support of modest quality, one has case-report support for a different harm than the one named, and ten are untested classical assertions so far as PubMed shows; the coincidence on urine and stool does not transfer credibility to the rest of the list, and the unsearched Indian databases could change the Ayurveda-specific picture.","summary":"Charaka devotes a whole Sutrasthana chapter to the proposition that certain bodily urges, once they have arisen, should not be voluntarily held back, and that a different class of urges should be held back. Thirteen physical urges are named as adharaniya (not to be suppressed): urine, faeces, semen, flatus, vomiting, sneezing, eructation, yawning, hunger, thirst, tears, sleep and laboured breathing after exertion. For each, the text names the disorders that suppression is said to produce and a treatment for those disorders. A second and opposite list, the dharaniya vegas, comprises mental and moral impulses (greed, grief, fear, anger, pride, shamelessness, envy, excessive attachment, and impulses of harsh, false or untimely speech, of harming others, of theft and of illicit sexual congress) which should be restrained. The chapter then continues into exercise in due measure and moderation generally, so the underlying principle is presented as one of non-obstruction of natural physiological flows combined with restraint of the mind. Sushruta treats the same thirteen urges in Uttaratantra 55 under the disease name udavarta, adding a fourteenth type arising from unwholesome food and drink, and also names suppression of urges as a cause and a thing to avoid in individual Chikitsasthana chapters. Vagbhata (Ashtanga Hridaya Sutrasthana 4) opens his chapter on the non-production of disease with the same instruction; his list verse names thirteen urges but includes cough and omits eructation, which he then treats separately, so he covers fourteen.","contested":[{"question":"Does suppressing urges cause disease, or does disease cause the suppression?","positions":["Charaka treats suppression as the originating cause, with the disorders following from obstructed vata; Sushruta Uttaratantra 55 states the same mechanism explicitly.","The paediatric constipation literature reverses this: painful defaecation comes first and withholding is the learned response that perpetuates it. In the urological literature, dysfunctional voiding involves sphincter dyssynergia that is not simply voluntary postponement, and in Koff 1998 infrequent voiding is one part of a composite syndrome in children who already have reflux.","Klauser 1990 cuts across both: in twelve healthy adults with no antecedent pain or disease, one week of deliberate withholding slowed colonic transit, which is the direction Charaka asserts. It shows suppression can initiate constipation-like change in the short term; it does not show that this becomes disease, so neither direction excludes the other."]},{"question":"Is shukra vega (semen) genuinely non-suppressible?","positions":["Charaka lists it among the thirteen (Su 7.3, retas) and treats it as a physical urge like urination, with sexual congress among the remedies (7.11). Sushruta Ut 55 and Vagbhata AH Su 4.1 and 4.19-21 do the same; Vagbhata's remedies include 'priyah striyah', agreeable women.","Charaka's own mirror list in the same chapter requires suppression of the urge to stri-bhoga where it harms others (7.29), Vagbhata's mirror list (4.24) names raga (attachment) among urges to be held, and Charaka Sutrasthana 11 makes brahmacharya one of the three supports of the body. The passages retrieved qualify the suppressible urge as illicit or harmful rather than as sexual desire as such, which may dissolve the tension, but no retrieved passage states the reconciliation and the commentaries were not retrieved. Modern Ayurvedic writing generally sidesteps this."]},{"question":"Is the list thirteen items long, and is it the same across Charaka, Sushruta and Vagbhata?","positions":["Charaka names thirteen adharaniya vegas (Su 7.3-4), and Sushruta's enumeration, retrieved from Bhishagratna's Uttaratantra 55 sections 2-4, names the same thirteen in a different order and calls the resulting disorders thirteen types of udavarta. On the passages retrieved, the two lists match item for item.","Sushruta adds a fourteenth udavarta from unwholesome food (apathyaja), so his chapter has fourteen types though thirteen urges. Vagbhata's list verse (AH Su 4.1) also has thirteen items but a different thirteen: kasa (cough) is in and udgara (eructation) is out, and he then treats eructation anyway at 4.8, so his chapter covers fourteen urges. 'Thirteen' is therefore stable between Charaka and Sushruta and not a fixed feature of the tradition."]},{"question":"Are the mental urges to be suppressed a medical doctrine or an ethical one?","positions":["They appear in a medical chapter with the physical urges, use the same verb (dharayet) with the sign reversed, and Vagbhata keeps the pairing (AH Su 4.24). Charaka 7.52 later attributes mental disturbances of the same kind to prajnaparadha, which is a medical category.","The stated reward (7.30) is dharma, artha and kama, and the list (theft, untruth, adultery, violence) is a moral code. Reading it as psychosomatic medicine imports a modern frame the text does not use, but reading it as purely ethical ignores its placement."]},{"question":"Is udavarta the classical umbrella name for all disorders of suppressed urges?","positions":["In Sushruta Uttaratantra 55 it is exactly that: thirteen types of udavarta named from the thirteen urges, with a general treatment rule for all of them.","In Charaka Su 7 the word does not occur in the retrieved Sanskrit; the disorders are named urge by urge without an umbrella term. In Vagbhata AH Su 4.2 udavarta is one consequence of suppressing flatus only. Treating udavarta as the general classical name, as this record's earlier version did, follows Sushruta's usage and should be attributed to him."]}],"notKnown":["Whether suppressing the urge to ejaculate (shukra vega) causes any of the disorders Charaka Su 7.10 names (genital pain, languor, heart pain, urinary retention).

What is quotable from a public-domain translation is small and definite: Charaka defines vikriti as deviation from normal, makes it the second item of the ten-fold examination whose stated purpose is 'ascertainment of the measure of strength (of the patient)', lists the factors by which the derangement's strength is graded, and gives the three grades. That is all. No procedure is attached to any of it, and the Sushruta parallel is a list of things to observe that does not use the prakriti/vikriti axis. The record previously called this basis 'clear and quotable', which was true of the definition and false of the method, and the phrase is withdrawn: the quotable part is not the operational part. The operational part, the eight-fold examination with pulse and tongue at its centre, is not in Charaka or Sushruta. Both public-domain translators say so in their own voice (Kaviratna's note at Indriya Sthana, p. 871; Bhishagratna's Introduction, p. lxvii), the project's own search of both scans finds no pulse procedure, and the earliest text in which this record has located pulse examination is Sharngadhara Samhita Purva Khanda 3, now quoted in Sanskrit from an archive.org scan. The attribution of the eight-fold list as a named set to Yogaratnakara rests on secondary literature; neither it nor Bhavaprakasha was retrieved. Two adjacent doctrines supply what Charaka's definition lacks and are now cited: khavaigunya, which explains why a disturbed dosha produces disease at one site (Su.Su. XXIV; Ca.Ci. XV; Ca.Ni. IV on the conjunction of cause, dosha and dushya), and the sama / nirama judgement, for which Vagbhata gives ten signs and a treatment rule, that sama doshas are not to be expelled until ripened (A.H.Su. 13/23-24, 27, 28-29, Sanskrit only).\n\nTHE MEASUREMENT SIDE. When pulse and tongue examination have been measured for inter-rater reliability, the one study located gives average weighted kappa 0.07 for pulse and 0.17 for tongue, with the null hypothesis of random rating not rejected for any of 105 doctor pairs on tongue (PMID 24191170); the companion pulse analysis ranges from poor to moderate (28664059); a single expert's self-consistency on pulse was 0.42 (27257530). These are among the lowest chance-corrected figures this record has encountered for a clinical assessment; the earlier version said 'some of the lowest ... recorded for any clinical assessment', which is a comparison across fields that no search behind this record supports, and it is withdrawn. In real patients, agreement on constitutional and functional entities such as agni sat between 0 and 0.4 while raw agreement on the final label reached 95% (30653338), which means the consensus label is not being produced by the component assessments in any traceable way. A 2024 vignette study (39183608) shows the disagreement persists when every clinician receives identical written case information, so it is not solely an artefact of hands-on technique.\n\nINSTRUMENTATION. Pulse-acquisition hardware exists (Nadi Tarangini, 18002428, 2007) and a 2024 review counts 67 sensor papers (38815517). In the papers retrieved here the reference standard is the practitioner: the 2007 paper states the system 'is being evaluated by Ayurvedic practitioners', and the 2017 pilot (29103852) compares sensor positions, not diagnoses, and has no reference diagnosis at all. An instrument validated against practitioner judgement cannot be shown to exceed that judgement's reliability, which is the circularity a critic finding named; the record states it for the papers it has read and does not generalise it to the 67 it has not. The one Ayurveda-framed tongue-image classifier located (37702608) reports 99.17% accuracy with no statement of label provenance in its abstract.\n\nCODING. ICD-11 Chapter 26 Module 2 (release 2026-01, held in a sibling repository snapshot) codes constitution patterns (SS50-SS56, prakriti by dosha) and per-dosha derangement stages (SR10-SR1E: prakopa, sanchaya, vriddhi, prasara, kshaya) and an ama state (SS15), but contains no entity for vikriti by name, no examination method and no grading of strength. The output of a vikriti assessment is thus internationally codeable; its method and warrant are not. The WHO's own Bulletin perspective (41180267) states that the chapter's inter-rater reliability requires dedicated study.\n\nBOUNDED NEGATIVES. Within the searches named in modernCoverage: no operational definition of a vikriti state validated against an external criterion was located; no prospectively tested biomarker for dosha derangement, agni or ama was located; no study was located that tests whether a vikriti assessment predicts outcome or treatment response. These are statements about what was searched, not about the literature as a whole; DHARA, the AYUSH Research Portal, IEEE Xplore and Scopus were not searched. Beyond the reliability studies, the indexed literature retrieved on vikriti and its sub-concepts consists of narrative reviews that restate the classical categories in modern physiological vocabulary and propose candidate biomarkers as future work.","summary":"Vikriti is the assessment of a patient's current deranged state. Charaka defines it in one sentence, as deviation from what is normal, and sets it against prakriti as its reference point: where prakriti is what the person is by birth, vikriti is what has gone wrong now. In Charaka it is the second of the ten items of patient examination (dashavidha pariksha), and the text attaches to it a list of factors to be weighed, cause, dhatu, dosha, prakriti, place and time, together with the symptoms, by which the derangement is graded strong, middling or weak. That is the whole of what Charaka says about vikriti as such, and this record now says so plainly: the definition, the position in the list and the grading factors are quotable from a public-domain translation, but no examination procedure is attached to any of them. The procedure clinicians actually use for vikriti assessment, the eight-fold ashtavidha pariksha with pulse (nadi) and tongue (jihva) at its centre, is not in Charaka or Sushruta. The two public-domain translators of those texts both say so in their own voice, and the earliest text in which this record has located pulse examination is the Sharngadhara Samhita, Purva Khanda 3, quoted here in Sanskrit. So the quotable part of vikriti doctrine is not the operational part, and the operational part is not classical. Two adjacent doctrines give vikriti its content once a disturbed dosha is found: khavaigunya, the site defect that explains why disease lands where it does, and the sama / nirama distinction, the judgement that undigested matter (ama) is or is not bound up with the disturbed dosha, which Vagbhata makes the condition for whether the doshas may be expelled at all. Both are now cited from located verses and cross-referenced to their own records. Modern reliability measurement of pulse and tongue examination has produced chance-corrected agreement in the slight range (mean weighted kappa 0.07 and 0.17 in the one inter-rater study retrieved), which is among the lowest figures this record has encountered; no systematic comparison with other clinical assessments was made and none is claimed. Instrumented pulse acquisition and tongue-image classification exist and are cited; in the papers retrieved here the reference standard they are evaluated against is the practitioner's own judgement, which is the quantity whose reliability is in question.","contested":[{"question":"Is nadi pariksha a legitimate part of classical Ayurvedic diagnosis?","positions":["Traditional practice treats it as central and defends it by long historical use, and some Ayurvedic sources read scattered references to dhamani or sira in the samhitas as implicit pulse examination. Bhishagratna, himself a Kaviraj, concedes the absence from Sushruta and explains it as a division of labour with a separate pulse treatise (Introduction, p. lxvii).","Textual scholarship, and much Ayurvedic writing itself, accepts that Charaka and Sushruta contain no description of pulse examination and that the method appears later. Kaviratna states the absence flatly in his note at Indriya Sthana ('Suçruta also is silent, like Charaka, on the pulse'), and this record has located the method no earlier than Sharngadhara Purva Khanda 3. If so, the emblematic vikriti method has no samhita-period authority. Whether Sharngadhara is the EARLIEST text to carry it is a priority claim this record does not make; see notKnown."]},{"question":"What is the relation between vikriti and the disease diagnosis?","positions":["Vikriti is a separate axis: two patients with the same named disease can have different vikriti and therefore different treatment, which is the standard justification for individualisation. The classical ground for the separateness is khavaigunya and the conjunction requirement (Ca.Ni. IV): the same dosha produces different diseases by site and dushya.","The 2019 reliability data show agreement is better on disease entities than on constitutional and functional ones, which suggests the named disease is doing most of the work and the vikriti layer adds variance rather than information."]},{"question":"Is high raw agreement on a final diagnosis evidence of a working method?","positions":["Practitioners point to 95% agreement on the consensus final diagnosis as showing the method works in practice.","Methodologists point out that raw agreement is inflated by unequal prevalence of categories and that chance-corrected kappa for the same study's components was 0 to 0.4; the two figures cannot both describe a reproducible process."]},{"question":"Can vikriti be assessed without first establishing prakriti, and is the pair circular?","positions":["Charaka's definition makes vikriti deviation from the individual's own norm, so prakriti must be established first.","In practice many assessments grade current dosha states against a population norm rather than the individual's constitution, which is a different quantity. The literature retrieved here does not consistently distinguish the two, and no study comparing them was located.","The circularity, added on revision: in a sick patient prakriti is usually inferred from the same examination that produces the vikriti finding, so the reference and the deviation are read off one observation. The prakriti record carries the measurement side of this (prakriti inter-rater kappa 0.28 in PMID 24191170); if the reference is that unreliable, the deviation from it inherits the unreliability before any vikriti-specific error is added."]},{"question":"Is ama a measurable state?","positions":["It is treated clinically as assessable through tongue coating, appetite and other signs, and a validated ama instrument exists within the Ayurvedic literature. The classical sign list is now quoted (A.H.Su. 13/23-24), and ICD-11 TM2 carries an ama-state category (SS15).","No external biochemical or imaging correlate has been established in the literature retrieved here; the 2026 rheumatoid arthritis pilot is exploratory and the ama instrument's validation is internal to the same tradition, so the construct has no independent anchor."]},{"question":"Does instrumenting the pulse escape the reliability problem?","positions":["Device proponents hold that a sensor removes the subjectivity of finger palpation and that classifiers trained on recorded waveforms will be reproducible by construction.","Reproducibility of the signal is not validity of the label. In the papers retrieved here the labels come from practitioners (18002428) or there is no reference diagnosis at all (29103852), so a classifier can at best reproduce the practitioner's kappa-0.07 judgement more consistently. The field's own 2024 review concedes that 'procedure standardization is also required' (38815517). Added on revision after a critic finding; the circularity is stated for the retrieved papers, not asserted of the whole literature."]}],"notKnown":["What an operational definition of a vikriti state would be.

The instrumented work retrieved here (Nadi Tarangini, PMIDs 18002428 and 29103852) records the artery but either uses the practitioner as the reference or compares sensor positions without any diagnosis, so no study located here tests a practitioner's dosha reading against an instrumented measurement of the same artery as an independent criterion. Restated on revision; the earlier version said no study had tested pulse findings against instrumented measurement, which was too broad once the device literature was retrieved.","Whether tongue coating indexes anything beyond oral hygiene, smoking, hydration and medication; no study located here controlled for these while testing the ama association.","Whether agni has any measurable correlate.

In the records examined for this entry (the PubMed searches listed in searchLog, run on 2026-10-06, and the references carried from the first pass) there is no operational definition of it, no validated measure, no biomarker, and no study in which a person's vyadhikshamatva was assessed at baseline and found to predict subsequent illness. That is a statement about the records examined, not about the field. The term-level searches are spelling-sensitive (4, 2, 0 and 3 hits for four transliterations; 6 combined), and the construct-adjacent searches (rasayana AND immunomodulation, 57 hits; prakriti AND immune AND ayurveda, 12; ojas AND ayurveda, 10; bala AND ayurveda AND immunity, 9) were counted and not screened, so a study that operationalises host resistance under other vocabulary may exist and would not have been found here. Of the six records the combined term search returns, two are narrative reviews that restate the classical account in immunological vocabulary and propose a correspondence (38702944, 32837101), one is a perspective piece (38176303), one a single case report in which 'need of good immunity (Vyadhi-Kshamatva)' is a clinical diagnosis (38306823), one a small two-active-arm trial that named vyadhikshamatva as an endpoint and operationalised it ad hoc (24501524), and one an uncontrolled acceptability study of an immunity kit (37303860). The 2025 cholesterol-as-ojas paper (41289791), found outside the term search, is a hypothesis paper that calls its own links correlative. The one controlled study found, AYURAKSHA (36052011), compares 101 kit users with 71 controls drawn without randomisation from 47,827 recipients and reports lower COVID-19 IgG positivity in the kit group; it tests a product, not the construct, and its design cannot separate the kit's effect from selection and exposure differences. The equation of vyadhikshamatva with immunity is the working assumption in each of these records; it is an interpretive overlay applied retrospectively, since the classical text describes no cells, no agents, no barrier and no memory, and defines resistance by a phenotypic checklist of body habitus, tissue adequacy, strength, nutrition and vitality (Su. 28.7), with the proportionate, hardy body of Su. 21.18-19 as its positive. That some items on the checklist (undernutrition, extremes of body mass) are also general predictors of infection outcome in modern epidemiology is not evidence for the Ayurvedic construct, because those predictors hold regardless of any theory about them, and this record does not use the overlap as support. Ojas, which supplies the concept's supposed mechanism, is identified with bala by Sushruta (Su.Su. 15.19, where the text itself marks the identification as a school position) and is seated in the heart and made the condition of life by Charaka (Ca.Su. 30.7-11); a vital principle whose absence is death is outside the class of things a laboratory parameter could measure. The two-part analysis of vyadhikshamatva into opposing disease strength and preventing disease arising is Chakrapani's gloss on Su. 28.7 (Ayurvedadipika, quoted in the classical section), not Charaka's text, and it is often cited as though primary. The honest summary is that this is a coherent classical construct carrying a host-susceptibility checklist that is stated as a list and not as a mechanism, and that it has not been operationalised, measured or tested in any record this entry examined.","summary":"Vyadhikshamatva is the classical term for a body's capacity to resist disease. Charaka introduces it by negation: not all bodies are capable of resisting disease (Su. 28.7), and he then lists the bodies that are not, the very fat, the very lean, those with poorly developed flesh, blood and bone, those lacking strength, those on unsuitable or insufficient food, and those of feeble vitality. The same chapter's own pair of terms is vyadhi-sahatva and a-vyadhi-sahatva, bodies that bear disease and bodies that do not. Charaka's chapter on the eight censurable constitutions supplies the positive counterpart: the man of proportionate build and compact frame, with firm senses, 'is not overcome by the strength of diseases', while the very fat and the very lean are 'always diseased' (Su. 21.16-18). The concept is tied to bala (strength), which Charaka classifies as threefold: sahaja (innate), kalaja (dependent on age and season) and yuktikrita (acquired through regimen, diet and exercise) (Su. 11.36). Sushruta identifies ojas with bala outright, as the quintessence of all the dhatus from rasa to shukra, and marks that identification as his own school's doctrine (Su.Su. 15.19); Charaka seats ojas in the heart and makes life depend on it (Ca.Su. 30.7-11). Vyadhikshamatva is therefore not a separate system but a composite of constitution, tissue adequacy, nutrition, strength and ojas, and it is explicitly variable between individuals. Modern Ayurvedic writing routinely equates it with immunity; the classical texts describe no cells, no agents of infection and no mechanism, and the equation is an interpretive overlay.","contested":[{"question":"Is vyadhikshamatva the same as immunity?","positions":["Yes, the standard position in modern Ayurvedic literature, which treats it as the classical anticipation of immunology and measures it with immunoglobulins and infection frequency","No: the classical description is a host-susceptibility checklist inside a dose-response account of disease causation, with no agents, cells, specificity or memory; equating it with immunity imports content the sources do not contain","Partially: it overlaps with what is now called host resistance or resilience, a broader and less specific notion than immunity"]},{"question":"Is ojas a substance or a principle?","positions":["Substance: Sushruta describes it as having colour, unctuousness, stability and mobility (Su.Su. 15.21), as quantifiable, and as capable of depletion, which invites a material reading (Bhishagratna rendered it 'albumen'; others have proposed cholesterol or HDL-C)","Principle: Charaka states that without its loss there is no death (Ca.Su. 30.11), making it coextensive with life rather than a measurable constituent","Bhishagratna's own footnote records the dispute inside the tradition, noting that several authorities held ojas to be only one of the essentials of vitality and not identical with vital power","The Sanskrit of Su.Su. 15.19 itself marks the identification of ojas with bala as a school position (svashastrasiddhantat), so the disagreement Bhishagratna footnotes is acknowledged in the text; and the Charaka line Kaviratna renders 'The Ojas is the strength of the body' (30.11) is textually unstable, the Trikamji-based text reading yach chharirarasasnehah with no word for strength and Kaviratna footnoting that the line is read differently"]},{"question":"Is vyadhikshamatva primarily constitutional or modifiable?","positions":["Constitutional: Charaka's list at Su. 28.7 is dominated by body habitus and tissue adequacy, largely given","Modifiable: one of the three balas (yuktikrita) is explicitly acquired through diet, exercise and regimen, and the whole rasayana literature depends on this","Charaka's own aetiologies of the two censured habitus mix the two: obesity at Su. 21.4 ends with bijasvabhava (the nature of the seed; Kaviratna: heredity) after seven behavioural causes, and leanness at 21.12 lists prakriti and jara (nature, ageing) alongside diet, over-purgation, grief and anger","No source quantifies the relative contribution, and no record examined for this entry has attempted to"]},{"question":"Where does the two-part analysis of vyadhikshamatva come from?","positions":["It is treated in most modern papers as a classical distinction, cited alongside Charaka Su. 28.7","It is in fact Chakrapani's commentarial gloss, not part of Charaka's text, and the distinction between preventing disease arising and limiting disease already present is a commentator's analysis","Confirmed in revision against the Ayurvedadipika on Su. 28.7, note 9: vyadhikshamatvam vyadhibalavirodhitvam vyadhyutpadapratibandhakatvam iti yavat (quoted in the classical section)"]}],"notKnown":["How vyadhikshamatva would be measured in an individual.

The Sanskrit section heading is about bala (balalakshanam), so ojas enters as the answer to what strength is. The Sanskrit itself marks the identification as a school position, svashastrasiddhantat ('by the settled doctrine of our own system'), which Bhishagratna renders as 'This view ... has been adopted in the present work'; his footnote on dissenting authorities is thus anchored in the text's own hedge. 'Albumen' and 'protoplasmic' are his 1907 biomedical glosses and no part of the Sanskrit. The functions in 15.20 (firm and well-developed flesh, unimpeded activity, clear voice and complexion, sense organs performing their work) are the observable correlates of bala in this school.","quote":"Now we shall describe the characteristic features of the strength-giving principles of the body, as well as the symptoms that mark their loss or waste.
