# prakopa (प्रकोप) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/prakopa/ An Ayurvedic technical term, rendered into English in 4 different ways across 5 sources. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | prakopa | | Devanagari | प्रकोप | | Also written | prakopaḥ, प्रकोपः, kopa, कोप, prakop | | Category, as gathered | kriyakala | | Grouped under | Causation and the course of disease | | Classical citations | 4 | | Citations checked | 2026-10-08 | ## How it is translated, and whether the translation holds Each rendering is given with the source that uses it. The assessment is ours. ### Stage of a dosha reaching the threshold WHO International Standard Terminologies on Ayurveda · ITA-4.6.8 (prakopaḥ), ch. 4, printed p. 114 · who-ista WHO description, verbatim: 'The second stage of disease manifestation, when dosha increases to reach the threshold at its own location. This term may also indicate physiological aggravation of dosha.' Re-read from the PDF. Two things matter: WHO chooses 'threshold', not 'aggravation', for the stage name; and WHO explicitly flags that prakopa has a second, non-staged sense.

The Sanskrit column at ITA-5.2.1.2 was re-read and does read 'vātaprakopaḥ/ vātavṛddhilakṣaṇam', so WHO does treat prakopa and vṛddhi as interchangeable at the dosha-disorder level, which cuts against the careful stage distinction in ITA-4.6.8.

Kaviraj Kunja Lal Bhishagratna (1907) · Sutrasthana ch. XXI, summary verse · public-domain-translation Bhishagratna offers a doublet rather than a single word. In the prose he also uses 'aggravated', 'excited' and 'aggravating causes' for the same root. ### (the source's rendering is a full definition and is not reproduced here) easyayurveda.com (Dr Raghuram Y.S. / Dr J.V.

Recorded for completeness only. ## The classical passages ### Sushruta Samhita Sutrasthana 21:27, checked against the source > तेषां प्रकोपात् कोष्ठतोदसञ्चरणाम्लीकापिपासापरिदाहान्नद्वेषहृदयोत्क्लेदाश्च जायन्ते । तत्र द्वितीयः क्रियाकालः ॥२७॥ Sanskrit mūla · https://www.siva.sh/sushruta-samhita/sutra-sthana/21/27 Gives the signs of prakopa (pricking and wandering pain in the koṣṭha, sour eructation, thirst, burning, aversion to food, nausea) and marks it the second kriyākāla. ### Sushruta Samhita Sutrasthana 21:27, checked against the source > The aggravated condition of the humours gives rise to pain and moves the wind Vayu) in the bowels; it further occasions acid eructations, thirst, burning sensations, aversion to food, vomiting and nausea. Any of these symptoms should be regarded as the second occasion which calls for medical aid. tr. Kaviraj Kunja Lal Bhishagratna (1907) · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122917.html Bhishagratna's English for the prakopa stage, including his rendering of the stage-marker as 'the second occasion which calls for medical aid'. ### Sushruta Samhita Sutrasthana 21:19-26, checked against the source > अत ऊर्ध्वं प्रकोपणानि वक्ष्यामः । Sanskrit mūla · https://www.siva.sh/sushruta-samhita/sutra-sthana/21/19 Verses 19-26 are a long catalogue of prakopaṇa, the causes that provoke each dosha and blood, plus the times and seasons of spontaneous provocation. Important lexicographically: prakopaṇa (the provoking cause) is a distinct word from prakopa (the stage), and the bulk of the chapter's prakopa material is aetiological, not staging. Only the section-opening sentence is quoted; the verse range is a description of what follows it, not a quotation claim. ### Charaka Samhita Chikitsasthana Lesson III (Jwara / Treatment of Fever), as numbered in Kaviratna's translation:41-42, checked against the source > The accumulated bile becomes provoked in the season of autumn through the heat of the sun, and quickly generates fever (that is characterised by excited bile). tr. Kaviraj Avinash Chandra Kaviratna · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt Kaviratna renders the prakopa idea as 'provoked' or 'excited' rather than 'aggravated', and shows the accumulation-to-provocation sequence operating seasonally in Charaka. Re-verified: the sentence sits inside a block closed by the inline number '41-42', which is confirmed adjacent in the retrieved text; the quoted sentence is one sentence within that numbered block, not the whole of it. ## Not to be confused with - **prakopaṇa (nidāna / provoking cause).** Su.Su. 21.19-21.26 uses prakopaṇa for the CAUSES that provoke a dosha (diet, conduct, season). Prakopa is the resulting state. English 'aggravation' is used for both in most sources, which destroys the distinction. - **vṛddhi.** Vṛddhi is quantitative increase. Prakopa in the kriyakala sense is a change of state, the dosha reaches a threshold and is about to overflow. WHO's chapter 5 equates vātaprakopaḥ with vātavṛddhilakṣaṇam (confirmed in the Sanskrit column), so even WHO is inconsistent between its own chapters; treat any source that equates them as making a substantive claim, not just a wording choice. - **kopa (in Vagbhata's caya-kopa-praśama).** In the three-fold seasonal scheme, kopa is followed by spontaneous praśama. In the six-fold scheme, prakopa is followed by prasara. Same root, different downstream commitment. - **sañcaya.** Both occur in the dosha's own seat. The distinguishing claim in the sources is degree or threshold: WHO says prakopa is when the dosha 'increases to reach the threshold at its own location'. The boundary is not operationally defined in anything I could retrieve. ## Renderings that do not hold - 'inflammation'. Imports a specific modern histopathological process. Prakopa is a state of a dosha, and the signs Sushruta lists (sour eructation, thirst, nausea, aversion to food) are not inflammatory signs. - 'anger' / 'rage'. A literal reading of the root kup-. Doshas are described figuratively as enraged, but in a lexicon this reads as an emotion and is wrong. - 'flare-up' meaning a clinical exacerbation of an existing disease. Prakopa in kriyakala precedes disease. Borrowing 'flare' from rheumatology or dermatology puts it at the wrong end of the sequence. ## Open questions Recorded rather than resolved. - Where exactly sources place the sañcaya/prakopa boundary, and whether any of them defines it by anything other than severity of the same signs. - Whether WHO intends ITA-4.6.8 (stage) and ITA-5.2.x (disorder) to be the same referent under two headings, or two distinct entities. - What Dalhana says on 21.27 about how the threshold is characterised, no public-domain English of Dalhana was located. ## Citation Age Ayurveda Nighantu, "prakopa", https://nighantu.ageayurveda.com/lexicon/prakopa/, CC BY 4.0.
