## How it is translated, and whether the translation holds

Each rendering is given with the source that uses it. The assessment is ours.

### Sweat

WHO International Standard Terminologies on Ayurveda (2022) · ITA-2.4.5 svedaḥ; 'The mala of fat, the function of which is to withhold moisture in the skin.' · standard

WHO classes sweat as the mala of FAT (dhātumala), following Ca.Chi.15/18 'malaḥ svēdastu mēdasaḥ', not as an āhāramala; the function clause follows AH Su 11/5 kleda-vidhṛti.

Recorded to separate the mala (svedaḥ) from the therapy (svedana), which share a stem and are routinely confused in English.

### sweat

Charaka Samhita, tr. Avinash Chandra Kaviratna (1896-1913) · Sutrasthana Lesson XXVIII; Chikitsa Lesson XV his 17 (printed as 'sweet', a misprint/OCR error) · translation

### perspiration

Sushruta Samhita, tr. Kaviraj Kunja Lal Bhishagratna (1907) · Sutrasthana XV · translation

Bhishagratna consistently prefers 'perspiration'; Kaviratna 'sweat'. A pure register difference.

### perspiration (from fat)

WHO International Standard Terminologies on Ayurveda (2022) · ITA-2.4.1 malaḥ description · standard

WHO itself uses 'perspiration' inside the mala definition and 'Sweat' as the headword.

## The classical passages

### Charaka Samhita Sutrasthana 28:4 (standard), checked against the source

> किट्टात् स्वेदमूत्रपुरीषवातपित्तश्लेष्माणः ... पुष्यन्ति| / kiṭṭāt svēdamūtrapurīṣavātaPittaślēṣmāṇaḥ ... puṣyanti| — Kaviratna: 'From the Refuse arise urine, sweat, faeces* wind, bile, and phlegm'

tr. Sanskrit from carakasamhitaonline; English by Avinash Chandra Kaviratna · https://www.carakasamhitaonline.com/index.php/Vividhashitapitiya_Adhyaya ; https://archive.org/download/BIUSante_47357/BIUSante_47357_djvu.txt

Sweat is the FIRST mala Charaka names as nourished from kiṭṭa (sveda-mūtra-purīṣa).

### Charaka Samhita Chikitsasthana 15:18 (standard); Kaviratna's printed 17, checked against the source

> मलः स्वेदस्तु मेदसः / malaḥ svēdastu mēdasaḥ — Kaviratna: 'while sweet forms the ‘Kitta’ of adeps'

tr. Sanskrit from carakasamhitaonline; English by Avinash Chandra Kaviratna · https://www.carakasamhitaonline.com/index.php/Grahani_Chikitsa ; https://archive.org/download/BIUSante_47357/BIUSante_47357_djvu.txt

Sweat is the mala of medas (fat). This is why WHO and NAMASTE class sweat as dhātumala, not āhāramala. Kaviratna's 'sweet' is a misprint for 'sweat' and 'adeps' = medas.

### Sushruta Samhita Sutrasthana 15:5 (siva.sh numbering); Bhishagratna prints no verse numbers, checked against the source

> मेदः स्नेहस्वेदौ दृढत्वं पुष्टिमस्थ्नां च ... स्वेदः क्लेदत्वक्सौकुमार्यकृत् / mēdaḥ snēhasvēdau dr̥ḍhatvaṁ puṣṭim asthnāṁ ca ... svēdaḥ klēdatvaksaukumāryakr̥t — Bhishagratna: 'whereas perspiration tends to moisten the skin.'

tr. Kaviraj Kunja Lal Bhishagratna (English); Sanskrit from siva.sh · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122907.html ; https://www.siva.sh/sushruta-samhita/sutra-sthana/15/

Two statements in one sūtra: medas produces sneha and sveda; and sveda's function is kleda and softness (saukumārya) of the skin. Bhishagratna compresses this to 'moisten the skin' and drops saukumārya.

### Sushruta Samhita Sutrasthana 15:11 and 15 (siva.sh numbering), checked against the source

> स्वेदक्षये स्तब्धरोमकूपता त्वक्शोषः स्पर्शवैगुण्यं स्वेदनाशश्च; तत्राभ्यङ्गः स्वेदोपयोगश्च [11] ... स्वेदस्त्वचो दौर्गन्ध्यं कण्डूं च [15] — Bhishagratna: 'Similarly the waste, absence or scanty formation of perspiration is followed by such symptoms as numbness about the pores of the hair, and dryness of the epidermis (skin). The sense of touch is perceptibly affected, and perspiration is entirely stopped. The medical treatment in such a case consists in the application of medicated unguents, lubrications, diaphoretics, and adoption of measures (that tend to produce a copious perspiration).' ... 'Similarly, an increased secretion of perspiration is attended with an itching of the skin which emits a bad odour.'

tr. Kaviraj Kunja Lal Bhishagratna (English); Sanskrit from siva.sh · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122907.html ; https://www.siva.sh/sushruta-samhita/sutra-sthana/15/11-15

Sveda-kṣaya signs (stiff hair follicles, dry skin, altered touch, cessation of sweating) with treatment by abhyaṅga and svedana; sveda-vṛddhi signs (bad odour, itching). Note the Sanskrit itself prescribes sveda(na) therapy for sveda(mala)-kṣaya, which is the root of the English confusion between the two words. Charaka Su 17 has NO sveda-kṣaya verse; Sushruta supplies it.

### Ashtanga Hridaya Sutrasthana 11:5 (GRETIL numbering; GRETIL records a variant 11.5c 'svedasya keśa-vidhṛtir'), checked against the source

> avaṣṭambhaḥ purīṣasya mūtrasya kleda-vāhanam | svedasya kleda-vidhṛtir vṛddhas tu kurute 'nilaḥ || 5 ||

tr. none (no public-domain English exists) · http://gretil.sub.uni-goettingen.de/gretil/1_sanskr/6_sastra/7_ayur/vagaah_u.htm

Sweat's function is kleda-vidhṛti (holding moisture in), the direct source of WHO 2.4.5 'withhold moisture in the skin' and NAMASTE SAT-B.462. The GRETIL variant 'keśa-vidhṛti' (holding the hair) is noted; a human should check which reading Arunadatta adopts.

### Ashtanga Hridaya Sutrasthana 11:14 and 22 (GRETIL numbering), checked against the source

> svedo 'ti-sveda-daurgandhya-kaṇḍūr evaṃ ca lakṣayet | ... || 14 || ... svede roma-cyutiḥ stabdha-roma-tā sphuṭanaṃ tvacaḥ || 22 ||

tr. none (no public-domain English exists) · http://gretil.sub.uni-goettingen.de/gretil/1_sanskr/6_sastra/7_ayur/vagaah_u.htm

Vāgbhaṭa's sveda-vṛddhi (excess sweating, bad odour, itching) and sveda-kṣaya (hair fall, stiff hair, cracking skin) signs; NAMC CC-1/CC-2 cite these verses.

### Ashtanga Hridaya Sharirasthana 3:63 (GRETIL numbering), checked against the source

> kaphaḥ pittaṃ malāḥ kheṣu prasvedo nakha-roma ca || 63 ||

tr. none (no public-domain English exists) · http://gretil.sub.uni-goettingen.de/gretil/1_sanskr/6_sastra/7_ayur/vagaah_u.htm

Vāgbhaṭa's dhātu-mala list uses prasveda for sweat, in the same position (after the orifice-malas, i.e. mala of medas) as Charaka Chi 15/18.

## Not to be confused with

- **svedana (therapy).** Induced sweating / fomentation (WHO ITA-9.2.36; one of the pūrvakarma). Same stem, different category. Sushruta Su 15/11 prescribes svedana FOR sveda-kṣaya, so the two co-occur in one sentence. Over-sudation has its own code (WHO ITA-5.76.8 svedana-atiyogaḥ) distinct from svedavṛddhiḥ (ITA-5.4.11).
- **svedavaha srotas.** The channel (Ca.Vi.5/8); separate record. The earlier record in this corpus found that neither WHO's body-channel block nor NAMASTE SAT-B lists the channel, though both code its disorder.
- **sveda as a symptom.** In Charaka Su 17/23 and 17/33 'svēdaḥ' appears as a SIGN (sweating in pitta-type head and heart disease); PubMed hits for 'sveda ayurveda' are all case reports using the word in this sign sense. Not the mala entry.
- **kleda.** The moisture that sweat holds in the skin (AH 11/5 kleda-vidhṛti) and urine carries away (kleda-vāhana); sveda is the agent, kleda the substance.
- **āhāramala vs dhātumala.** The textbook 'trimala' (stool, urine, sweat) groups sweat with the food-wastes, but Charaka Chi 15/18, AH Sha 3/63, WHO 2.4.1/2.4.5 and NAMASTE SAT-B.457/462 all make sweat the mala of medas (dhātumala). The grouping and the derivation do not agree.
- **Charaka's eighteen kṣayas.** Kaviratna's footnote at Su 17/63 counts stools, urine and five orifice-secretions as the seven mala-kṣayas; sweat is not among them, and Su 17 has no sveda-kṣaya verse. 'Charaka describes sveda-kṣaya' would be unsupported.

## Renderings that do not hold

- 'detoxification through sweat' / sweat removes toxins. No retrieved classical source assigns sweat an eliminative function; Su.Su.15/5 (kleda, saukumārya) and AH Su 11/5 (kleda-vidhṛti) make sweat RETAIN moisture in the skin. Elimination of kleda is assigned to urine, not sweat.
- sveda = svedana ('sweating therapy'). Category error between mala and karma; see distinguishFrom.
- 'moisten the skin' as the whole function (Bhishagratna). Drops tvak-saukumārya (softness of skin) from Su.Su.15/5, and inverts the direction of AH 11/5 (holding moisture in vs applying moisture).

## Open questions

Recorded rather than resolved.

- Textual variant at AH Su 11/5c: kleda-vidhṛti vs keśa-vidhṛti (GRETIL records both). Which commentators prefer which was not checked.
- Why the 'trimala' grouping (stool, urine, sweat) became standard in teaching when the Bṛhattrayī derive sweat from medas; no primary-text source for 'trimala' as a term was located (PubMed 'trimala' 0 records; WHO and NAMASTE have no trimala headword).
- Whether Charaka anywhere states sweat's function (as opposed to origin) was not established.
