# kapha (कफ) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/kapha/ An Ayurvedic technical term, rendered into English in 8 different ways. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | kapha | | Devanagari | कफ | | Also written | śleṣman, ślēṣmā, shleshma, kaph, balāsa (Vedic), soma (contextually) | | Category, as gathered | dosha | | Grouped under | Dosha and its subtypes | | 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. ### Kapha, doṣha responsible for cohesiveness WHO International Standard Terminologies on Ayurveda (2022) · ITA-2.1.3.1; Sanskrit given as śleṣmā, kapha · standard Quoted exactly as printed, including the typo 'doṣha' in the published PDF. WHO's description names stability, unctuousness, lubrication, immunity and cohesion, and earth and water as the predominant elements.

Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122907.html Kapha's functions are lubrication, healing, growth, tissue-building, strength and stability. Every one of them is constructive; none is pathological. This is the clearest single refutation of 'phlegm'. ### Sushruta Samhita Sutrasthana 21, checked against the source > The Kapha is white, heavy, oily, slimy and cool. In its normal state, it is possessed of a sweet taste, which is followed by a saline one in its reactionary transformation (chemical reaction) when deranged or vitiated. tr. Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122917.html The guṇas of kapha, and the normal/deranged taste shift that Ayurvedic diagnosis uses. ### Charaka Samhita Sutrasthana 1:61 (Kaviratna prints this as aphorism 80, evidently an OCR error for 60), checked against the source > Heavy, cold, mild, watery, sweet, stable, and slimy, these attributes of phlegm are cured by objects having adverse attributes. tr. Avinash Chandra Kaviratna · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt The seven guṇas of kapha in lawfully quotable English. The printed aphorism number in this scan is corrupt and the verse number is inferred from sequence. ### Charaka Samhita Sutrasthana 17:117, checked against the source > प्राकृतस्तु बलं श्लेष्मा विकृतो मल उच्यते| स चैवौजः स्मृतः काये स च पाप्मोपदिश्यते||११७|| / prākr̥tastu balaṁ ślēṣmā vikr̥tō mala ucyatē| sa caivaujaḥ smr̥taḥ kāyē sa ca pāpmōpadiśyatē||117|| tr. none quoted (Sanskrit mula only) · https://www.carakasamhitaonline.com/index.php/Kiyanta_Shiraseeya_Adhyaya Normal śleṣman is strength and is identified with ojas; vitiated śleṣman is called mala. The single most important verse for kapha, because it makes the normal/abnormal distinction constitutive of the term rather than incidental. ## 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. - **[Tridosha: vata, pitta and kapha as the regulatory principles of the body](https://nighantu.ageayurveda.com/concept/tridosha-theory/)** (as Kapha): Principle of cohesion and structure: joint lubrication, unctuousness, stability, healing of sores, bulk. Gunas at Ca. Su. 1.61: guru, shita, mridu, snigdha, madhura, sthira, picchila (heavy, cold, soft, unctuous, sweet, stable, slimy). Sushruta locates five kaphas by seat at Su. Su. 21/14 (amashaya, chest, tongue-root and throat, head, joints) but the Sanskrit of that aphorism names none of them; the names kledaka, avalambaka, bodhaka, tarpaka, shleshaka appear in this record only as Bhishagratna's headings and footnotes, and their first classical occurrence was not established here ## Not to be confused with - **śleṣman.** Treated as a synonym by WHO ISTA (ITA-2.1.3.1 gives 'śleṣmā, kapha'). Sushruta uses śleṣman as the primary term and kapha as secondary; some scholastic traditions distinguish them by register rather than reference. - **ojas.** Charaka Sutrasthana 17/117 says normal śleṣman is ojas in the body, yet Sushruta Sutrasthana 15 defines ojas as the essence of all seven dhātus. The two texts do not agree, and the disagreement is unresolved. - **kleda / kledaka.** Kleda is moisture as such; kledaka-kapha is one subtype (WHO ITA-2.1.3.3). Neither is kapha. - **meda (fat) and rasa (plasma/chyle).** Sushruta Sutrasthana 15 lists rasa, rakta, māṃsa, medas etc. as dhātus, parallel to but distinct from the doṣas. Kapha-increase and medo-increase have different signs. - **kapha prakṛti.** WHO ITA-2.8.5, 'Body constitution with a predominance of kapha'. Constitutional, not a current-state claim. - **mucus / sputum.** A visible secretion. Kapha includes synovial lubrication, tissue anabolism, immunity and patience (WHO ITA-2.1.3.8), none of which is sputum. ## Renderings that do not hold - phlegm. Kaviratna's rendering and the commonest. Assigns the doṣa the properties of one waste product; cannot carry vṛṃhaṇa (tissue building), ropaṇa (wound healing), balakṛt (strength) or kṣamā (patience). - mucus. Narrower still than 'phlegm' and equally unable to cover the anabolic and psychological functions. - water. Confuses doṣa with mahābhūta; WHO ISTA names earth and water together as predominant, not water alone. - the earth element. Same category error in the other direction. - the stagnant / heavy dosha. Popular-wellness framing that treats kapha as intrinsically undesirable, contradicting Charaka Sutrasthana 17/117, where normal śleṣman is strength and ojas. ## Open questions Recorded rather than resolved. - The Charaka 17/117 identification of normal kapha with ojas versus the Sushruta Sutrasthana 15 definition of ojas as the essence of all dhātus is a genuine intertextual conflict; which reading the commentators (Chakrapani, Dalhana) take was not established here. - No kapha-specific peer-reviewed literature was located. ## Citation Age Ayurveda Nighantu, "kapha", https://nighantu.ageayurveda.com/lexicon/kapha/, CC BY 4.0.
