doṣa-dūṣya-sammūrcchanā: what the term means and how it is translated
doṣa-dūṣya-sammūrcchanā is an Ayurvedic technical term. It is rendered into English in 5 different ways across 6 sources, 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.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
Provoked and circulating dosha may get localized in specific microchannels/organs/tissues (dosha-dushya sammurcchana).
Charak Samhita Online (Charak Samhita Research, Training and Skill Development Centre), 'Shat-kriya Kala' article · section IV, Localization stage at other site (sthansamshraya) · modern reference work (in copyright)
The source does not translate the compound at all; it uses the Sanskrit as a technical label attached to the sthana-samshraya stage. This is the pattern across modern Ayurvedic academic writing: the term is used untranslated and glossed by its mechanism.
Charak Samhita Online, 'Shat-kriya Kala' article · section V, Stage of manifestation (vyakti) · modern reference work (in copyright)
The source's rendering runs to a full definition and is not reproduced here, because this project has not cleared that source for quotation.
The same source attaches the term to TWO different kriyakala stages (sthana-samshraya in section IV and vyakti in section V) within one article. That internal inconsistency is itself the finding: the term does not have a single agreed stage-location even in contemporary Ayurvedic pedagogy.
disease develops through the interaction of disturbed doshas with susceptible body tissues

NO ENTRY
WHO International Standard Terminologies on Ayurveda (2022) · searched the full extracted text of the 608-page PDF for 'sammūrcchana', 'sammurchana', 'sammūrchana', 'saṃmūrcchana' and 'dūṣya' compounds; the only hit for dūṣya is ITA-2.2.2 'A bodily structure which can be vitiated by aggravated doṣa' = dūṣyam · standard · our paraphrase of the source, not its words
WHO ISTA has no entry for this compound. It codes the six kriyakala stages individually (ITA-4.6.6 to 4.6.12) including sthānasamśrayaḥ 'Stage of a dosha localizing outside its location', but never names the dosha-dushya union as a term. A lexicon entry therefore cannot cite WHO for this headword.

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 21 · checked against the source
The physician, who fully knows about the accumulation (Sancaya), disturbance or aggravation (Prakopa), expansion (Prasara), and differentiating traits of the deranged humours (Bheda), and is well conversant with the specific localities in which they are respectively confined in the course of their expansion (Sthana-samshrayam), and with the symptoms which they respectively exhibit in connection with the incidental disease (Vyakti), is alone worthy of that epithet.
This is the shat-kriyakala verse, the classical locus modern writers point to when they use 'dosha-dushya-sammurchana'. It names six stages including sthana-samshraya; it does NOT contain the compound dosha-dushya-sammurchana, and Bhishagratna's English contains no word for the dosha-dushya union.
Sushruta SamhitaSutrasthana 21 · 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.
Opening of the Sthana-Samshraya section. Establishes that the classical text describes doshas lodging in a site and producing site-specific diseases, i.e. the mechanism the modern compound names, expressed without any term for the union itself.

Charaka's definition of samprapti and its synonyms jati and agati. Recorded here to bound the claim: Charaka's treatment of pathogenesis names samprapti and its six subdivisions (Ni.1/12) and never uses sammurchana. Sanskrit quoted; the English on that page is the 2020 CSRTSDC translation and is not quoted.
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.
Not to be confused with
- samprapti
- Samprapti is the whole causal sequence from nidana to bheda and is a defined classical term with its own synonyms (Cha.Ni.1/11) and six subdivisions (Cha.Ni.1/12). Sammurchana, as used today, names one event inside that sequence. Treating them as equivalents collapses a process into a moment.
- sthana-samshraya
- Sthana-samshraya is the fourth kriyakala, a classical stage named in Sushruta Su.21 with a retrievable verbatim text. Dosha-dushya-sammurchana is a later descriptor for what is said to happen at that stage. The stage has classical standing; the descriptor does not, on the evidence gathered.
- khavaigunya
- Khavaigunya is the pre-existing defect or weakness in a channel or tissue that permits the lodging. Sammurchana is the lodging/union itself. Modern sources sometimes run them together; khavaigunya is the precondition, not the event.
- murchana / murchita (as in taila-murchana, ghrita-murchana)
- A pharmaceutical processing operation on oils and ghee, from the same root. Entirely unrelated to pathogenesis, and a live collision risk in any glossary that indexes on the string 'murchana'.
- sannipata
- Sannipata is the coming-together of the three doshas with one another. Sammurchana as used here is the coming-together of dosha with dushya (tissue). Both are 'combination' words and are routinely conflated in English summaries.
Renderings that do not hold
- fusion of doshas and tissues. Implies an irreversible material merging. The classical mechanism (Su.Su.21) is lodging and localisation of a mobile dosha in a susceptible site, which the same chapter says can be reversed at an earlier stage. 'Fusion' overstates the physical claim.
- coma / fainting / stupefaction. A dictionary-driven error. Sammūrcchanā shares a root with mūrcchā, which does mean fainting or stupor, and that sense is what a general Sanskrit dictionary returns first. It is not the sense in this compound.
- dosha-dushya combination. Flattens the term to mere co-occurrence. The point of the concept in modern usage is a pathological interaction at a defective site, not that dosha and dushya are both present, which they always are.
- pathogenesis. 'Pathogenesis' is the standard English for samprapti, which is the whole sequence. Using it for sammurchana loses the distinction between the process and the event and makes the two terms indistinguishable in English.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Is the compound doṣa-dūṣya-sammūrcchanā attested in any samhita mula text, or does it first appear in a commentary (Chakrapani on Charaka, Dalhana on Sushruta, Vijayarakshita/Madhukosha on Madhava Nidana)? Nothing retrieved settles this.
- If commentarial, which commentator and at which verse? Search summaries repeatedly attributed it to 'Charaka Nidana Sthana chapter 1' but no retrieved page showed the compound in that chapter.
- Does the term properly belong to sthana-samshraya (4th kriyakala) or to vyakti (5th)? One single modern source uses it for both.
- Is the term in NAMASTE? The portal could not be queried.
