# Dosha-dushya-sammurchana (a modern Ayurvedic term for the meeting of disturbed dosha and susceptible tissue)

> Canonical version of this page: https://nighantu.ageayurveda.com/concept/dosha-dushya-sammurchana/

## How much weight this concept bears

Read this as a record about a term, not about a demonstrated mechanism. 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.

The 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.

What 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.

On 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.

Empirically 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.

A 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.

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.

## What is contested, and by whom

These are the questions on which the sources genuinely disagree. Each position is given as
its source states it. No position is presented as the settled answer, because none of them is.

### Where does the compound 'dosha-dushya-sammurchana' come from?

This is contested.

- 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 commentarial candidates (Madhukosha on Madhava Nidana, Chakrapani on Charaka, Dalhana on Sushruta) remain unread, so the origin is unestablished rather than disproved.

### Is sammurchana a distinct event, or just a name for the sthana-samshraya stage?

This is contested.

- Most modern teaching places sammurchana at sthana-samshraya, the fourth kriyakala, making it the mechanism of that stage.
- Other presentations treat sammurchana as spanning localisation and manifestation, or as the phase producing premonitory symptoms, which makes it a description of a stage boundary rather than an event. Sources do not settle this.
- One modern source attaches the term to two different kriyakala stages, sthana-samshraya and vyakti, within a single article (recorded in data/terms/dosha-dushya-sammurchana.json).

### What determines the site of lodgement?

This is contested.

- The khavaigunya position: a pre-existing local defect in a channel, from injury, heredity, prior disease or repeated strain, decides where the dosha can settle.
- The Sushruta passage itself attributes lodgement more simply to where the humours happen to be 'incarcerated', comparing it to rain clouds pouring in the quarter of the sky where they form, with no requirement of a pre-existing defect. 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.

### Is dosha alone sufficient, or is a susceptible dushya necessary?

This is contested.

- 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.

### What does sammurchana mean?

This is contested.

- 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. On the retrieved evidence the pathological sense is modern usage rather than inherited vocabulary, though a single located occurrence cannot settle the history of the word.

### Should the headword be kept at all?

This is contested.

- Retire it: an unanchored compound with no retrievable defining verse and no operational criterion should not head a record, and the material belongs under sthana-samshraya, khavaigunya and dushya-vishesha, which are attested.
- Keep it, scoped: the term is in active use in teaching and in the journal literature, readers meet it first and meet it undefined, and the most useful thing a lexicon can do is say exactly what it rests on. This revision takes the second course and marks the headword's status explicitly in headwordStatus rather than letting the classical block imply an anchor.
- This is an editorial decision, and by the project's own rule it belongs to the drafting phase, not to gathering. It is recorded as unresolved.

## What is not known

Stated rather than left out. Where a negative has actually been searched for rather than
assumed, the entry says so.

- Whether the compound term appears in any of the three brihat-trayi Samhitas at all, and if so where. Secondary sources cite it to mutually inconsistent loci and none supplies a defining verse.
- What observable state constitutes sammurchana having occurred, as distinct from dosha merely being present at a site. No source gives a criterion.
- Whether clinicians agree on which dushya is involved in a given patient. Never measured. The nearest data (PMID 30653338) shows fair-to-poor agreement on the neighbouring judgements of prakriti and agni.
- Whether khavaigunya can be detected before disease appears. No marker, imaging finding, or test has been proposed and validated, which means the central predictive claim of the concept is untestable as currently stated.
- Whether the site-specific disease lists in Sushruta Sutrasthana 21 and Charaka Sutrasthana 28 agree with each other. I retrieved both but no source compares them systematically, and their tissue-to-disease mappings are not obviously identical.
- Whether any biological correlate of dosha-dushya combination exists. The single attempt I found (PMID 22557650, 1989) asserts biochemical correlation in vivax malaria without controls or pre-specified mapping, and has not been replicated.
- Whether treatment directed at the dushya rather than at the dosha changes outcomes. The doctrine implies it should; no trial has compared the two strategies.
- Where the compound first appears, if it is commentarial. The candidates named in the literature and in this project's term record are the Madhukosha of Vijayarakshita and Srikanthadatta on Madhava Nidana, Chakrapani's Ayurveda Dipika on Charaka, and Dalhana's Nibandha Sangraha on Sushruta Sutrasthana 21. None was read: no commentarial text was retrieved, and searching for the Devanagari compound returned only modern Ayurvedic teaching material. The record therefore cannot name a locus for its own headword, and says so instead of supplying one.
- Whether any mula verse defines dūṣya by enumerating the seven dhatus plus the three malas. The word dūṣya is attested in Charaka (Nidana 4, in nidāna-doṣa-dūṣya-viśeṣebhyaḥ) and Sushruta Sutra 15 names dosha, dhatu and mala as the three classes of bodily constituent, but the equation of dushya with sapta dhatu plus trimala comes, in what was retrieved, from Kaviratna's footnote at Nidana IV, from modern glossaries, and from WHO ISTA ITA-2.2.2. A verse that makes the enumeration under that name has not been located.
- Whether 'sammurchana' with the sam- prefix is also a technical term in Rasa Shastra, as one critic finding states. What was retrieved is mūrchana, the swooning or trituration samskara of parada and the pre-treatment of oils and ghee. The disambiguation is therefore written on the form that could be verified, and the sam- prefixed Rasa Shastra usage is recorded as unconfirmed.
- Whether the Charaka Nidana 4 conjunction requirement and the Charaka Vimana 6/7 dushya-vishesha claim are one doctrine or two, and whether the modern compound merges them. Nothing retrieved addresses the question.
- Whether Ashtanga Hridaya or Ashtanga Samgraha carries the compound. Neither was retrieved, and neither has a public-domain English translation, so any future citation has to rest on the Sanskrit mula.
- Whether NAMASTE, the AYUSH standardised-terminology portal, codes the term. The portal could not be queried without a browser session, so its coverage is unknown rather than absent.

## The terms this concept is built from

| Term | What it names |
| --- | --- |
| [dosha](https://nighantu.ageayurveda.com/lexicon/dosha/) | The disturbed functional factor (vata, pitta or kapha, and in Sushruta's scheme also rakta) that has already accumulated, aggravated and spread. |
| dushya | The tissue element that is spoilt. Literally 'that which is to be vitiated'. The word is attested in Charaka's own text (Nidanasthana 4, in the compound nidana-dosha-dushya-vishesha); its identification with the seven dhatus (rasa, rakta, mamsa, meda, asthi, majja, shukra) plus the malas comes, in the sources retrieved here, from a translator's footnote, from modern glossaries and from WHO ISTA, not from a verse that enumerates them under that name. |
| [khavaigunya](https://nighantu.ageayurveda.com/lexicon/khavaigunya/) | Defect or weakness in a channel or site, which is held to determine where the circulating dosha can lodge. A commentarial and textbook term rather than a phrase with a single retrievable Samhita verse. |
| [srotas](https://nighantu.ageayurveda.com/lexicon/srotas/) | The channel system through which dosha travels and in which the lodgement occurs; srotodushti (channel vitiation) is the stated mode of that lodgement. |
| sammurchana | The combining or intermixing itself, in modern Ayurvedic usage: dosha and dushya are said to form a pathological entity that neither was alone. This sense is supplied by modern usage. The dictionaries give the noun saṃmūrchana as congealing, thickening, accumulating, and as fainting or insensibility; the one occurrence of the word located in the Samhitas (Charaka Sutrasthana 24/48, sammūrcchitāni ... madyāni) is of strong liquors commingled, which Gangadhara glosses as militāni. See distinguishFrom. |
| adhishthana | The resulting seat of disease, the anatomical location that gives the disease its name and its clinical picture. |

## The classical passages

Each citation gives its address so a reader can check it in a printed edition, our account
of what it establishes, and the result of reading it against its source.

### Sushruta Samhita Sutra Sthana 21 (Vrana-prashna):within the sthana-samshraya section; the Bhishagratna page carries no verse numbers, and this project's verification pass (research/citation-verdicts-c1.json, entry 63) matched the passage to the Sanskrit numbered 29-33, the sthana-samshraya statement itself closing at ||33||, checked against the source

> Now we shall enumerate the names of the peculiar diseases, which are originated by the deranged and expanded humours, incarcerated in the different parts of the body. These humours, confined in the abdomen, give rise to Gulma (abdominal glands) tumours, internal abscesses (Vidradhi), abdominal dropsy, impaired digestion in the bowels, constipation (anaha), cholera (Visuchika) and dysentery.

tr. Kaviraj Kunja Lal Bhishagratna (1907-1916, public domain)

Site specificity: the same spread doshas produce entirely different diseases according to where they are 'incarcerated'. The passage continues site by site, naming prameha and urinary stone for the bladder, fistula and haemorrhoids for the anal region, erysipelas and kushtha for flesh, skin and blood, and granthi, apachi, arbuda and galaganda for fat. This is a reference for sthana-samshraya, which has its own record (data/concepts/shat-kriyakala.json, data/terms/sthanasamshraya.json). It does not contain the compound dosha-dushya-sammurchana and is not offered as evidence for it.

### Sushruta Samhita Sutra Sthana 21 (Vrana-prashna):closing passage of the chapter; no number printed on the retrieved page. This project's verification pass (research/citation-verdicts-c1.json, entry 64) places the chapter's closing Sanskrit verse at 21.40 and identifies the 'concourse of deranged humours' clause as Bhishagratna's connective rendering of the preceding sannipata material at 21.38-39, checked against the source

> A concourse of deranged humours, affecting and appearing in a particular part of the body, is called a boil or an ulcer (Vrana) which is derived from the root "Vri" to cover and is so called from the fact of its covering a particular part of the body or from its leaving a cicatrix which remains the whole life-time of the patient.

tr. Kaviraj Kunja Lal Bhishagratna (1907-1916, public domain)

Kept as an exhibit of a translator's word, not as a parallel for sammurchana. The earlier version of this record described 'concourse of deranged humours' as the closest public-domain English wording to sammurchana in the Samhita text. That claim is withdrawn: the verification pass found the clause to be Bhishagratna's own connective phrasing over the chapter's sannipata material, and sannipata is the union of the doshas with one another, not of dosha with dushya. The object defined here is also a wound or ulcer specifically, not disease in general. Treating 'concourse' as the English of sammūrchanā would be the translator's voice absorbed as doctrine, which is the defect this project has already recorded three times.

### Sushruta Samhita Sutra Sthana 21 (Vrana-prashna):no number printed on the retrieved page; matched by this project's verification pass (research/citation-verdicts-c1.json, entry 65) to the Sanskrit verses 29-30, checked against the source

> The aggravated, or the abnormally irritated deranged humours, whether permeating the whole or half of the system or restricted to any particular part or member of the body, give rise to disease in the place of their incarceration, like rain clouds pouring down in the quarter of the sky where they are formed. The deranged humours, not excessively (slightly) aggravated, lie inoperative coating the internal passages (Margas) of the body and thus bring about a fresh disease, if subsequently agitated by any disturbing causes.

tr. Kaviraj Kunja Lal Bhishagratna (1907-1916, public domain)

Disease arises where the dosha lodges, and a dosha that lodges without producing disease can lie latent in a channel and produce disease later when re-agitated. Note what the passage does not say: it does not use the word khavaigunya and does not require a pre-existing defect at the site. This is a reference for khavaigunya's classical background (data/concepts/khavaigunya.json), not for this headword.

Source: https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122917.html

### Charaka Samhita Sutra Sthana 28 (Vividhashitapitiya):Kaviratna's aphorism 15, his number printed after the aphorism; in Trikamji numbering the two sentences straddle the closing clause of 28.7 and 28.8, per this project's verification pass (research/citation-verdicts-c1.json, entry 66), which quotes both Sanskrit sentences. The earlier version of this record mapped it to 28.8 alone, checked against the source

> Through these causes, the wind, bile, and phlegm, being excited in particular parts of the body, produce different diseases. The faults becoming excited in particular places such as the food-fluids and others, produce particular diseases. We shall now, O Agnivesa, declare which diseases arise from which places becoming the seats of the excited faults.

tr. Avinash Chandra Kaviratna (1896-1913, public domain)

Charaka's statement of the site-specificity principle, followed in the chapter by a tissue-by-tissue list: anorexia, tastelessness, hiccup, heaviness, fever and lassitude from dosha excited in rasa; kushtha, erysipelas, bleeding disorders, splenomegaly and jaundice from dosha excited in rakta; and so on through meda, asthi, majja and shukra. A reference for the principle under its own description, not for the compound.

Source: https://archive.org/details/BIUSante_47357

### Charaka Samhita Sutra Sthana 28 (Vividhashitapitiya):Kaviratna's aphorisms 39-40, his numbers printed after the aphorisms; Sanskrit 28.31-33, per research/citation-verdicts-c1.json, entry 67, which quotes 28.31, 28.32 and the opening of 28.33, checked against the source

> Arrived at the ducts they sometimes stay there, unimpelled by any other force. Unless the region and the time be undisposed thereto, they do not become excited, for they await some cause of excitement.

tr. Avinash Chandra Kaviratna (1896-1913, public domain)

The latency claim: what has reached a channel may sit there without producing disease, waiting for a provoking cause. This is the classical material behind the modern idea that a defective site plus a trigger, not dosha alone, produces disease. A reference for that latency doctrine, not for the compound.

Source: https://archive.org/details/BIUSante_47357

### Charaka Samhita Nidana Sthana 4 (Prameha Nidana):Kaviratna's aphorism 3, his number printed after the aphorism. The Sanskrit clause is numbered 4 in the Trikamji-based text retrieved (carakasamhitaonline, Prameha Nidana): Kaviratna runs one behind here, as this project has documented elsewhere. The Sanskrit sentence continues beyond the clause quoted, checked against the source

> iha khalu nidānadoṣadūṣyaviśeṣebhyo vikāravighātabhāvābhāvaprativiśeṣā bhavanti

Sanskrit mūla

> Here (in the world), verily, from the particular characteristics of 'Nidana' or causes, 'doshas' or faults, and 'dushyas' or the ingredients or 'dhatus' composing the body, arise the manifestation, the non-manifestation, and the partial manifestation of diseases in general.

tr. Avinash Chandra Kaviratna (1896-1913, public domain)

Added. The nearest classical statement retrieved to the content the modern compound names, and the locus the record previously lacked for the dushya half: dūṣya stands here in Charaka's own text, in a three-term compound with nidāna and doṣa, and the manifestation, non-manifestation or partial manifestation of disease turns on the particular characteristics of all three. Kaviratna's inline gloss, 'the ingredients or dhatus composing the body', is his, not the text's. The verse does not contain sammūrchana and does not say that dosha and dushya fuse.

Source: https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt

### Charaka Samhita Nidana Sthana 4 (Prameha Nidana):Kaviratna's aphorism 4, continuing the same passage. No modern verse number is asserted: the retrieved Trikamji-based page prints verse 4 in abbreviated form and I did not establish where that edition ends it, checked against the source

> When these three, viz., the characteristics of causes, faults, and ingredients, are not united in sequence, no manifestion of disease takes place. Or, when they, through absence of predominance, unite as weak factors, no manifestation occurs of disease ; or there is lateness in manifestation ; or the manifestation takes place in a weak form ; or all the symptoms laid down do not show themselves.

tr. Avinash Chandra Kaviratna (1896-1913, public domain)

Added. The explicit conjunction requirement: unless cause, dosha and dushya come together in sequence and with sufficient force, disease does not manifest, or manifests late, weakly or partially. This is the classical sentence closest to what modern writers mean by the compound, and it is worth noticing that it names no fusion and no defect in the site, only a joint condition on three factors. ('manifestion' is as the Kaviratna OCR prints it.)

Source: https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt

### Charaka Samhita Vimana Sthana 6 (Roganika Vimana):Kaviratna's aphorism 10, printed after a block of several sentences. The quoted sentence corresponds to the Sanskrit numbered 6.7 in the Trikamji-based text retrieved (carakasamhitaonline, Roganika Vimana). Kaviratna bundles several Trikamji verses under one aphorism number here, so the two numbering systems must not be mixed and no one-to-one mapping is asserted, checked against the source

> prakupitāstu khalu te prakopaṇaviśeṣāddūṣyaviśeṣācca vikāraviśeṣānabhinirvartayantyaparisaṅkhyeyān

Sanskrit mūla

> When excited, the faults, in consequence of difference of exciting causes as also of difference of the elements vitiated, generate innumerable diseases.

tr. Avinash Chandra Kaviratna (1896-1913, public domain)

Added. Disease variety is generated by two differences, that of the exciting cause and that of the dushya vitiated. Kaviratna renders dūṣyaviśeṣāt as 'difference of the elements vitiated' and supplies the word dushya only in his footnote, where he also notes that the correct reading is dūṣyaviśeṣāt and not dravyaviśeṣāt. This is the strongest classical warrant retrieved for the claim that which tissue is involved helps fix which disease appears; it contains no term for a union of dosha with dushya.

### Sushruta Samhita Sutra Sthana 15 (Dosha-dhatu-mala-kshaya-vriddhi-vijnaniya):opening of the chapter. No verse number is asserted: Bhishagratna prints no Sanskrit verse numbers, and this is the chapter's introductory sentence, checked against the source

> Since the human body is constituted of humours, (Doshas), excretions (Mala), and the fundamental principles (Dhatus) of blood, marrow, etc., hear me discourse on the features which are peculiar to each of them.

tr. Kaviraj Kunja Lal Bhishagratna (1907-1916, public domain)

Added for the dushya half of the compound. Sushruta's own framing names three classes of constituent, dosha, dhatu and mala, and the chapter title is built from them. It is this triad that modern usage partitions into dosha on one side and dushya (dhatu plus mala) on the other. The passage does not use the word dushya and does not make that partition itself. Retrieved twice independently: the wisdomlib reproduction of Bhishagratna and the archive.org scan of the printed translation, where the wording is identical.

## What the research actually shows

Every paper located for this concept, with what it measured and what it does and does not
establish. The assessment is ours.

### Reliability of Ayurvedic Diagnosis for Knee Osteoarthritis Patients: A Nested Diagnostic Study Within a Randomized Controlled Trial.

J Altern Complement Med · 2019 · PMID 30653338 (https://pubmed.ncbi.nlm.nih.gov/30653338/)

Four Ayurvedic experts assessing the same 30 knee osteoarthritis patients reached only fair-to-poor chance-corrected agreement (Fleiss and Cohen kappa between 0 and 0.4) on core diagnostic components including prakriti and agni, although percentage agreement on the final consented diagnosis was 95 percent, and agreement on disease-related entities exceeded agreement on constitutional entities.

**How much it shows.** Empirical inter-rater reliability study nested in an RCT; small (30 patients, 4 raters), single condition. It does not measure agreement on dosha-dushya assignment specifically, but it is the best available evidence on whether the judgements that feed such an assignment are reproducible, and the answer is that several are not.

### Myth and reality of "theory-driven individualised practice" in Ayurveda: Mapping physicians' approaches using case-based scenarios.

Indian J Med Ethics · 2024 · PMID 39183608 (https://pubmed.ncbi.nlm.nih.gov/39183608/)

141 experienced Ayurveda practitioners answering five clinical vignettes showed significant lack of consensus on diagnoses, on interventions and on their understanding of pathophysiology, with conflicting opinions; the authors conclude theoretical constructs do not uniformly determine prescriptions or individualisation.

**How much it shows.** Empirical cross-sectional vignette survey. Convenience sample and hypothetical cases are real limitations, but it is direct evidence that practitioners do not converge on a single dosha-dushya account of the same case.

### Critical appraisal of Doshavaha Srotas.

Ayu · 2012 · PMID 23723638 (https://pubmed.ncbi.nlm.nih.gov/23723638/)

Conceptual appraisal of doshavaha srotas, arguing for correlating vatavaha, pittavaha, kaphavaha and sarvavaha sira with corresponding srotas, in order to explain how doshas reach and vitiate particular sites.

**How much it shows.** Textual and conceptual review with no empirical component. It is exegesis of the channel doctrine underlying sammurchana, not evidence for it.

### Correlation of certain biochemical changes with dosha-dushya intolvement in some vishamajwaras (p.vivax malaria) and its therapeutic utility.

Anc Sci Life · 1989 · PMID 22557650 (https://pubmed.ncbi.nlm.nih.gov/22557650/)

Reports biochemical changes before and after treatment in 180 cases of anyedyushka and tritiyaka vishamajwara (identified with P. vivax malaria) and attempts to correlate those changes with the dosha-dushya involvement assigned in each case.

**How much it shows.** Weak. Old (1989), in a journal with no DOI recorded for the article, uncontrolled, no blinding, no pre-specified mapping, no chance-corrected statistics, and the correlation is asserted rather than tested. It is nonetheless one of the very few attempts anywhere to attach a measurement to a dosha-dushya assignment, which is itself a statement about how thin this literature is.

### Tongue coating, severity of Ama, and disease activity in patients with Rheumatoid Arthritis: A pilot study.

J Ayurveda Integr Med · 2026 · PMID 42142499 (https://pubmed.ncbi.nlm.nih.gov/42142499/)

Pilot study relating tongue coating, scored by the Winkel tongue coating index from smartphone images, to Ama severity by a validated Ama instrument and to disease activity (CDAI) in rheumatoid arthritis, treated as the prototype of amavata.

**How much it shows.** Small empirical pilot, and one of the few studies that operationalises a pathogenesis component at all. It addresses ama rather than dosha-dushya-sammurchana directly, is a pilot without a confirmatory study, and the PubMed record carries a DOI that does not match the article, so only the PMID is given.

Suthar OP, Gupta, Marolia, Prakash, 'Dosha Dushya Sammurchana in Disease Manifestation - A Review', J Ayurveda Integr Med Sci 10(6). Retrieved to read its reference list. It gives Charaka Chikitsasthana 28/20-23 and Sushruta Sutrasthana 15/18 as its classical loci for the compound, cites Ashtanga Hridaya, Ashtanga Samgraha and Madhava Nidana Part II, and quotes no Sanskrit verse containing the compound.

**How much it shows.** Weak as evidence, decisive as a record of usage. Narrative review, no method section, journal not PubMed-indexed. It is cited here for what it cites, not for what it concludes: the two classical addresses it supplies were retrieved and do not support the term, which is the central finding of this revision.

## Open questions on this record

Recorded rather than resolved.

- Does the Madhukosha on Madhava Nidana 1 contain the compound, and at what locus? Needs a Sanskrit commentarial text this pass could not retrieve.
- Where does the Trikamji-based verse 4 of Charaka Nidana 4 end, so that Kaviratna's aphorism 4 can be mapped to a modern number?
- Can the Charaka Sutra 24 numbering discrepancy (Kaviratna 49-50 against the retrieved Sanskrit 48) be resolved against a printed Trikamji edition?
