Avinash Chandra Kaviratna · Sūtrasthāna ch. 28, his verses 13-14; 'These bodies which are the reverse of those described above are capable of resisting diseases.' · public-domain-translation Kaviratna has no noun for vyādhikṣamatva; he renders it only predicatively, of bodies. ### All bodies, again, are not equally liable to disease. Charaka Samhita, tr. Avinash Chandra Kaviratna · Sūtrasthāna ch. 28, his verse 11 (= CS Sū. 28.7 in modern numbering) · public-domain-translation This renders 'na ca sarvāṇi śarīrāṇi vyādhikṣamatve samarthāni bhavanti'. Kaviratna inverts the polarity: the Sanskrit says bodies are not all CAPABLE of resistance; he writes they are not all LIABLE to disease. Semantically close, logically not identical. ### immunity / disease resistance / resistance to disease Standard Indian BAMS textbook and journal usage · ubiquitous in Ayurvedic periodical literature, e.g. PMID 24501524 title uses the untranslated term · textbook · our paraphrase of the source, not its words The commonest working rendering; carries immunological baggage the classical term does not. ## The classical passages ### Charaka Samhita (Agniveśa, with Cakrapāṇidatta's Āyurvedadīpikā) Sūtrasthāna 28 (Vividhāśitapītīya):28.7, checked against the source > na hi sarvāṇyapathyāni tulyadoṣāṇi na ca sarve doṣāstulyabalā na ca sarvāṇi śarīrāṇi vyādhikṣamatve samarthāni bhavanti tr. none (Sanskrit mūla quoted) · https://gretil.sub.uni-goettingen.de/gretil/corpustei/transformations/plaintext/sa_agniveza-carakasaMhitA-parts-comm.txt The locus classicus. The word appears not as a defined entity but inside a triple denial: not all unwholesome things are equally harmful, not all doṣas equally strong, and not all bodies capable of vyādhikṣamatva. ### Cakrapāṇidatta, Āyurvedadīpikā commentary on Charaka Samhita Sūtrasthāna 28.7 Sūtrasthāna 28:commentary gloss no. 10 on 28.7, checked against the source > vyādhikṣamatvaṃ vyādhibalavirodhitvaṃ vyādhyutpādapratibandhakatvamiti yāvat tr. none (Sanskrit quoted) · https://gretil.sub.uni-goettingen.de/gretil/corpustei/transformations/plaintext/sa_agniveza-carakasaMhitA-parts-comm.txt Chakrapāṇi EQUATES vyādhikṣamatva with vyādhibalavirodhitva and with vyādhyutpādapratibandhakatva. WHO ISTA splits these same three words into three separate term IDs with different definitions. This is the single most important disagreement in the record. ### Charaka Samhita, tr. Kaviratna (public domain) Sūtrasthāna 28:Kaviratna's verses 11-14 (= modern 28.7), checked against the source > All bodies, again, are not equally liable to disease. ... are incapable of resisting diseases.13 These bodies which are the reverse of those described above are capable of resisting diseases. tr. Avinash Chandra Kaviratna · https://archive.org/download/BIUSante_47357/BIUSante_47357_djvu.txt The earliest English rendering available for lawful quotation; shows the term was not treated as a technical noun in 1900. ## The concept record for this term A term entry answers what the word means. It does not answer whether the thing the word names is settled, and often it is not. That is what the concept record is for: it sets out the questions on which the sources disagree about this term, with each position attributed, and states what is not established. - [Vyadhikshamatva: resistance to disease](https://nighantu.ageayurveda.com/concept/vyadhikshamatva/) ## Where this term does work in the theory One concept record names this term as one of its components, and glosses it there as follows. - **[Ojas and the Ayurvedic Account of Resistance to Disease](https://nighantu.ageayurveda.com/concept/ojas-and-immunity/)** (as Vyadhikshamatva): The capacity both to resist the onset of disease and to withstand it once present. The term closest in function to 'immunity', though broader. ## Not to be confused with - **bala.** WHO ISTA ITA-2.2.27 lists both words under one entry, but bala is the positive capacity (classified sahaja / yuktikṛta / kālaja) while vyādhikṣamatva in CS Sū. 28.7 is specifically the body's competence to withstand disease. Every bala is not vyādhikṣamatva; Chakrapāṇi defines the latter by what it obstructs. - **vyādhibalavirodhitva.** Chakrapāṇi says they are the same thing (see quote). WHO ISTA ITA-4.8.26 makes it a separate entry, 'A natural, nonspecific type of immunity which defends the body whenever any disease occurs for the first time', an innate-immunity reading with no classical warrant given. A lexicon must not silently adopt either position. - **vyādhyutpādapratibandhakatva.** Again a Chakrapāṇi synonym, but WHO ISTA ITA-4.8.27 defines it separately as 'The defence mechanism of the body which intervenes to resist the occurrence or re-occurrence of diseases'. - **ojas.** Ojas is a substance-like entity (the essence of the dhātus); vyādhikṣamatva is a capacity predicated of the śarīra. Modern papers routinely conflate them; CS Sū. 28.7 does not mention ojas. - **immunity (biomedical).** The biomedical term denotes a specific organ-system. CS Sū. 28.7's account of bodies unable to resist is anatomical and nutritional (too fat, too thin, undeveloped flesh/blood/bone, weak, sustained on unsuitable food, on very little food, of little vitality) — nothing immunological. ## Renderings that do not hold - immune system. Turns a capacity into an anatomical system. Nothing in CS Sū. 28.7 or in Chakrapāṇi's gloss individuates a system; the qualifying factors listed are body habitus, tissue quality, diet and sattva. - immunity (unqualified). Defensible as shorthand and used by WHO ISTA, but it imports specificity/memory/antigen concepts. The classical term also covers resistance to non-infectious causation (apathya āhāra, prajñāparādha), which 'immunity' excludes. - immunity booster. Marketing usage. It treats vyādhikṣamatva as a quantity that can be raised by a product, whereas the classical passage treats it as a standing property of the constituted body. - resistance to infection. Narrows the term to infectious disease; the Charaka context is about vyādhi in general arising from diet and other rogaprakṛtis. ## Open questions Recorded rather than resolved. - Does any classical text other than Charaka use the word vyādhikṣamatva? Not found in the GRETIL Charaka-parts corpus beyond Sū. 28.7 and its commentary; Sushruta was not searched exhaustively for it. - Whether WHO ISTA's three-way split (ITA-4.8.25/26/27) rests on any commentarial authority, or is an editorial invention contradicting Chakrapāṇi. - Whether NAMASTE assigns a code to vyādhikṣamatva (portal unreachable). ## Citation Age Ayurveda Nighantu, "vyādhikṣamatva", https://nighantu.ageayurveda.com/lexicon/vyadhikshamatva/, CC BY 4.0.
