mala-parīkṣā: what the term means and how it is translated

mala-parīkṣā मलपरीक्षा is an Ayurvedic technical term. It is rendered into English in 4 different ways across 5 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.

excreta (domain 3 of aṣṭasthānaparīkṣā, ITA-4.7.4)

WHO International Standard Terminologies on Ayurveda (2022) · ITA-4.7.4, p.115 (PDF page 133) · comparator

WHO says 'excreta', not 'stool'; mala in WHO's broader usage covers all waste products.

'The waste products of the body formed during various stages of digestion and metabolism. Mala is one of the fundamental constituent of the human body along with Doṣa and Dhātu. They are of two classes: Āhāramala and Dhātumala. Āhāramala are: Mūtra (Urine) and Purīṣa (faces).' (mala, SK0121)

Shows that 'mala' alone is ambiguous (all wastes); in the eightfold scheme it means stool because mūtra is listed separately.

mala is the third of the eight sites, listed after mūtra (so here mala = stool, not wastes generally).

Stool signs by dosha, read from the Nirnaya Sagar page images rather than OCR: hard and dry in vata, yellow in pitta, white in kapha (v.1); all signs together in sannipata, and broken-up, frothy, rough and smoke-coloured (trutitam phenilam ruksam dhumalam) in vata-kopa, ash-grey (kapisa) in a combined vata-kapha disorder (v.2); bound, finely broken, yellow-dark from pitta with anila, slightly thick and slimy from kapha with pitta (v.3); dark, broken and yellowish, bound and white in tridosa, and when the stool passed is foul-smelling and cold (v.4) the physicians who know the dosas call it jirna, digested (v.5); tawny and lumpy stool indicates depleted mala-dosa (v.5-6); white, large and putrid-smelling in jalodara (v.6); dark in ksaya, raw-and-undigested, yellow with pain in the flank (v.7); extremely black, extremely white, extremely yellow or ruddy stool portends death, and stool that is intensely hot certainly so (v.7 and the unnumbered half-line); then a second series introduced by anyac ca: black for vata, yellow for pitta, somewhat red, white from kapha (v.8), raw in indigestion and well-formed when digested (v.9); and finally the asadhya signs, lumpy and dry in excessive agni, liquefied in weak agni, and foul-smelling with a sheen (candrika-yukta), which is the mark of the incurable (v.10). The section is attributed by the Yogaratnakara to the Rudra-tantra (rudratantrat), not to Harita.

Not to be confused with

mala (waste products generally)
In Ayurvedic physiology mala includes urine, sweat and dhātu-malas (NIA draft SK0121). In the eightfold scheme mala means stool only because mūtra is a separate site.
mūtra-parīkṣā / taila-bindu-parīkṣā
Urine examination is the second site and has its own elaborate oil-drop prognostic test; the two are often lumped as 'mala-mūtra parīkṣā'.
purīṣa
The specific word for faeces (WHO uses purīṣa compounds for stool signs, e.g. 'makṣikākrāntaṁ purīṣaṁ'); modern reviews use purīṣa-parīkṣā and mala-parīkṣā interchangeably.
koṣṭha-parīkṣā
Assessment of bowel habit (mṛdu/madhya/krūra koṣṭha) for purgation dosing is a different examination.

Renderings that do not hold

  • excretion examination. Over-broad; the Yogaratnakara section is specifically about faeces.
  • 'Mala pariksha = laboratory stool test'. The classical examination is by naked-eye colour, consistency, smell and a water-immersion test, not microscopy or chemistry (PMID 27011711 makes the same point).

Open questions

Recorded rather than resolved. Each one is something this entry cannot currently settle.

  • The attribution marker at the start of the Yogaratnakara mala-parīkṣā (OCR 'र्दतच्रात्', possibly 'हारीतात्', citing Hārīta) needs confirming from the page image.
  • Verse numbering of the section across editions.
