khavaiguṇya: what the term means and how it is translated
khavaiguṇya खवैगुण्य is an Ayurvedic technical term. It is rendered into English in 6 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

Functional alteration of body channels
WHO International Standard Terminologies on Ayurveda (2022) · Entry ITA-4.8.2, section 4.8, p. 115; Sanskrit srotovaiguṇyam / स्रोतोवैगुण्यम्; description "A functional and/or structural alteration of the body channels leading to a pathological process." · standards-body
IMPORTANT: WHO ISTA has NO entry for khavaiguṇya. Verified by full-text search of the 608-page PDF: the string 'khavaigu' returns zero hits and 'vaigun' returns only srotovaiguṇyam. WHO standardises the srotas-compound and not the kha- compound. Also note WHO assigns the identical English term 'Functional alteration of body channels' to ITA-4.8.3 (srotoduṣṭihetuḥ), so the standard does not distinguish the two in English at all.

owing to an obstruction in their natural passage
Sushruta Samhita, tr. Kaviraj Kunja Lal Bhishagratna (public domain) · Sutrasthana ch. XXIV, authoritative verse (= Su.Su.24/10) · public-domain-translation
This is Bhishagratna rendering the whole phrase 'yatra saṅgaḥ khavaiguṇyāt'. He does NOT give khavaiguṇya a distinct English equivalent; he merges it with saṅga. So there is no public-domain English rendering of khavaiguṇya as such.
defect in channels of transportation and transformation
Charak Samhita New Edition (CSRTDC), 'Kha vaigunya' article · carakasamhitaonline.com/index.php/Kha_vaigunya, DOI 10.47468/CSNE.2020.e01.s09.027, by Khandel S.K. & Baghel M.S., first published 15 Aug 2020 · modern-scholarly-edition · our paraphrase of the source, not its words
Recorded as a comparator. This edition's English is CC-licensed and in copyright, so it is paraphrased here rather than quoted. The same article supplies the etymology: 'Kha' literally means empty or vacant space; 'Vaigunya' means defect or deformity. It also states expressly that khavaigunya is DIFFERENT from srotodushti and that srotodushti occurs at a site where khavaigunya already exists.
any area or bodily part lacking normalcy or normal traits
Ali M, Sharma RK, Pareek P, 'Concept Of Khavaigunya and Srotodushti in Vyadhiutpati: A Review', Int. J. for Multidisciplinary Research 5(4), 2023 · IJFMR23045456, introduction; etymology sourced to Shabdakalpadruma pp. 267 and 335 · modern-journal-review
Telling detail: for the ETYMOLOGY of both halves of the word this review cites a nineteenth-century Sanskrit lexicon (Shabdakalpadruma), not a medical text. Its only classical citations are to Charaka and Ashtanga Hridaya passages about srotas and dhatvagni, none of which contains the word khavaiguṇya.
the impairment of the function integrity of the Srotas
Sharma S et al., Int. Res. J. Ayurveda & Yoga 6(12):98-102 (2023) · DOI 10.47223/IRJAY.2023.61218, section 3.12, of 'Khavaigunya or Srotovaigunya' · modern-journal-review
Treats khavaiguṇya and srotovaiguṇya as interchangeable, as most of the literature does. Also attributes the role of srotovaigunya at the sthanasamshraya stage to 'Dalhan Tika of Sushruta Samhita'.

Unretrieved. Given khavaiguṇya is a mechanism rather than a morbidity, a NAMC code would be unlikely.
The classical passages
Each citation gives its address so a reader can check it in a printed edition, our account of what the passage establishes, and the result of reading it against its source.
Sushruta SamhitaSutrasthana 24 (Vyadhi-samuddeshiya):10 · checked against the source
भवति चात्र- कुपितानां हि दोषाणां शरीरे परिधावताम् | यत्र सङ्गः खवैगुण्याद्व्याधिस्तत्रोपजायते ||१०||
THE locus classicus, and the ONLY mula-text occurrence of the word khavaiguṇya that I was able to verify anywhere. Of the aggravated doshas coursing through the body, disease arises at the place where they are arrested BECAUSE OF khavaiguṇya (defect of the kha, i.e. of the channel-space). This single verse is the entire textual basis of the concept; everything else in the literature is inference from it or from the sthana-samshraya stage of shatkriyakala.
Sushruta SamhitaSutrasthana XXIV:10 ('Authoritative verse on the Subject') · checked against the source
The deranged and aggravated humours, freely coursing through the body, give rise to a disease at the place in which they are incarcerated owing to an obstruction in their natural passage.
The only lawfully quotable English of the locus classicus. It also demonstrates that Bhishagratna did not recognise khavaiguṇya as a term of art: he renders it as 'an obstruction in their natural passage', which reads it as a second description of saṅga rather than as its cause.
Sushruta SamhitaSutrasthana 21 (Vrana-prashna):the shatkriyakala passage; sthana-samshraya is the fourth stage · address only, nothing quoted to check
Where the concept operates in the six-stage model: sthana-samshraya, the lodgement of the disseminated doshas in a particular site. The secondary literature (IRJAY 2023, IJRAP 2020, IJFMR 2023, CSNE) is unanimous that khavaiguṇya is what determines WHERE lodgement occurs. I located the chapter and confirmed it contains the six-stage sequence, but I could NOT verify a verse number or obtain a clean verbatim sentence tying khavaiguṇya to it, and the word does not appear in the English I retrieved. Recorded as located, not quoted.
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.
- Dosha-dushya-sammurchana (a modern Ayurvedic term for the meeting of disturbed dosha and susceptible tissue) as 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.
Not to be confused with
- srotoduṣṭi
- The tradition orders them in time: khavaiguṇya is the pre-existing defect or susceptibility in the channel; srotoduṣṭi is the vitiation that then occurs there when dosha meets dushya. The CSNE article states this explicitly. WHO ISTA, by giving srotovaiguṇyam and srotoduṣṭihetuḥ the SAME English term, erases the distinction. A lexicon should preserve it and flag the WHO collision.
- srotovaiguṇya (स्रोतोवैगुण्य)
- Treated as a synonym throughout the modern literature, and it is the form WHO standardised. But note it is srotovaiguṇya, not khavaiguṇya, that WHO carries, so the two words are not interchangeable at the level of a standards lookup even if they are in clinical usage.
- sthāna-saṃśraya
- The fourth stage of shatkriyakala, the EVENT of lodgement. khavaiguṇya is the pre-condition that determines where lodgement happens. Stage versus mechanism.
- bīja-doṣa / bīja-bhāga-avayava-doṣa
- Defect in the reproductive seed or in a specific part of it, Charaka's mechanism for congenital disease. Reviews treat bija dushti as one CAUSE of khavaiguṇya, not as the same thing.
- saṅga
- In Su.Su.24/10 saṅga is the arrest of the doshas and khavaiguṇya is its cause ('yatra saṅgaḥ khavaiguṇyāt'). They appear in one clause and are routinely collapsed, Bhishagratna himself collapses them.
Renderings that do not hold
- obstruction in the natural passage. Bhishagratna's own rendering, and the reason English readers of Sushruta never encounter the term. It reads khavaiguṇya as a restatement of saṅga, whereas the ablative khavaiguṇyāt makes it the CAUSE of saṅga.
- locus minoris resistentiae. A Latin tag imported by twentieth-century Ayurvedic writers. It is a reasonable analogy but it is not a translation, it carries specific connotations from European pathology, and presenting it as an equivalent gives the concept a spurious biomedical pedigree.
- genetic predisposition. One proposed subtype (IJRAP 2020) offered as the whole. The classical verse says nothing about heredity; the hereditary/congenital/acquired classification is explicitly labelled a hypothesis by its own author.
- khavaigunya as a stage of shatkriyakala. It is not one of the six. The six are sanchaya, prakopa, prasara, sthanasamshraya, vyakti, bheda. Khavaiguṇya is the condition that makes the fourth possible.
- tissue weakness / weak organ. Loses the channel reference. 'Kha' is the space or lumen of the srotas; the defect is in the channel-space, not in a tissue mass or an organ generally.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Whether khavaiguṇya occurs anywhere in the Charaka Samhita mula. I could not run an exhaustive negative check: the GRETIL Caraka e-text I searched covers only selected chapters. The dedicated reviews give no Charaka citation containing the word, which is suggestive but not proof.
- Whether Dalhana's commentary on Su.Su.24/10 or on Su.Su.21 supplies the definition that the secondary literature attributes to him. This is the single highest-value next step.
- Whether Chakrapani uses the term anywhere, and whether the equation of 'kha' with 'srotas' is his.
- Whether the sirā/dhamanī-level defect and the dhatvagni-level defect are two distinct classical mechanisms or one.
