anupāna: what the term means and how it is translated

anupāna अनुपान is an Ayurvedic technical term. It is rendered into English in 6 different ways, 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.

Any liquid which is taken soon after food. Drink should have properties opposite to that of food, but should not be incompatible with the particular food. It helps in easy movement, digestion and assimilation of the food particles.

Anupana (untranslated); 'fluid food or drink that is taken subsequently'; 'after-drink'; 'vehicle'

Charaka Samhita tr. A. C. Kaviratna, public domain · Su.27 anupana block and translator's footnotes; Fasciculus XIII abstract: 'Articles used as Anupana (i. e., as vehicles for medicines and as drinks with which a dinner or act of eating is to be concluded)'; Chikitsasthana footnote: ''Anupana' is after-drink. It means vehicle also.' · public-domain translation

Kaviratna explicitly flags two senses and says context decides; the most careful of the retrieved renderings.

after-potion(s) / after-drink / 'drinks and potions which are found to be beneficial when taken after a certain kind of food (Anupanas.)'

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.

I shall now speak of the effects of Anupana. Anupanas exercise a sedative and nutritive influence. They make the mind cheerful. They conduce to increase of energy. They produce the sensation of gratification after one has eaten. They moisten what is eaten (and thereby assist at digestion). They disjoin united food. They soften the food in the stomach. They cause the impurities to separate themselves from the food in the stomach. They cause the food to be digested. They contribute to that sensation of pleasure which arises after eating. They cause the food to extend its effects to all parts of the body.

Kaviratna's 'sedative' renders tarpayati (satiates/refreshes), not a CNS effect; his parentheses are glosses.

(Here occur some verses.) An Anupana that is suitable is certainly beneficial. It soon exercises a sedative and nutritive influence on the body. It causes easy digestion of the food that has been eaten. It conduces to strength and long life.

That fluid food or drink should be taken subsequently which in qualities is the reverse of the food taken previously. It should be remembered, however, that the subsequent fluid food should not be hostile to the upholding ingredients of the body.

Kaviratna's footnote here: 'The word 'Anupana,' it should be noted, implies not only fluid food or drink that is taken subsequently, — that is, at the conclusion of a course of eating, — but also such fluids as are used as vehicles of medicines. — T.'

As regards such subsequent fluid food or drink, that which is oily and hot is praised in excitements of the wind ; that which is sweet and cooling is praised in excitements of the bile ; that which is dry and hot is praised in excitements of the phlegm ; while in emaciation and waste, the juice of meat is highly beneficial.

Those persons the upper parts of whose bodies are afflicted with wind, those persons who are afflicted with asthma and consumption, those persons who are generally engaged in singing or speaking aloud or reading aloud, and those who have sores or wounds on the chest, should not drink water after having taken their food, for, if they drink, that water, remaining in their throat or chest, will destroy the oily secretions of the food previously taken, and generate many faults.

tr. A. C. Kaviratna · source

Contraindication of drinking water after a meal (Ca.Su.27.327-328). The Sanskrit names four classes who should not: (1) those with vata disturbed in the upper body (urdhvanga-maruta-avishta); (2) sufferers from hiccup, dyspnoea and cough (hikka-shvasa-kasin); (3) those engaged in singing, lecturing or recitation (gita-bhashya-adhyayana-prasakta); (4) those with chest injury (urasi kshata). Reason given: the water lodged in throat and chest destroys the sneha of the food and produces further dosha. Kaviratna's rendering 'asthma and consumption' is his, not the text's: the Samhita says hiccup, dyspnoea and cough, and says nothing of consumption (kshaya/rajayakshma). Parallel in Sushruta Su.46 below.

Sushruta SamhitaSutrasthana 46 (Annapana-vidhi):Sanskrit verse numbers not established; Bhishagratna prints none · checked against the source

Cold water and warm water, Asava (wine), Madya (spirits), the soup of Mudga pulse etc., the juice of acid fruits, sour paddy gruel, milk and essence of meat are generally used as drinks after a full meal. Of these, that alone which would prove beneficial to a person should be given him in an adequate quantity.

tr. K. L. Bhishagratna · source

Sushruta's list of anupanas. Same page: 'Of all kinds of after-potions, clear heavenly (atmospheric) water, kept in a pure vessel, should be deemed the best'; benefits: 'A proper after-potion taken after a meal brings on a fresh relish for food, increases the bulk of the body, acts as a spermatopoietic beverage, disintegrates the combination or accumulation of the deranged bodily humours, soothes the organism, increases the softness of the body, removes the sense of fatigue and exhaustion, brings on pleasurable sensations in its train, stimulates the appetite, subdues or pacifies the deranged bodily humours, allays the thirst, improves the complexion, and imparts tone and vigour to the system.'; contraindication: 'Hence, the use of an afterpotion is imperatively obligatory on all human beings, except those suffering from dyspnea, cough, ulcerative endocarditis (Urahkshata), ptyalism, aphonia, and from diseases affecting the part of the body situated above the clavicles.' ('ulcerative endocarditis' is Bhishagratna's gloss of urahkshata.)

Not to be confused with

sahapāna
Later pharmaceutical usage distinguishes a liquid taken together with the medicine (saha) from one taken after (anu). Classical source for this distinction was NOT retrieved; verify before use.
yogavāhī
A property of a substance (e.g., honey) to carry others' properties (PMID 28827948 frames it as a bioenhancer property); anupana is the administered liquid, not a property.
bioavailability enhancer / bioenhancer (e.g., Pippali)
Those are co-administered drugs; anupana may be plain water (Sushruta: atmospheric water is the best anupana).
pharmaceutical vehicle / excipient
An excipient is part of the dosage form; anupana is taken separately after/with it, and in Su.27 and Su.46 it is primarily a dietary after-drink.
pāna / peya (drinks in general)
Anupana is defined relative to a preceding food or drug, not as a class of beverage.

Renderings that do not hold

  • adjuvant. Modern dominant rendering; implies a second active agent, whereas classical anupana includes water and is defined by its relation (anu) to food/medicine.
  • vehicle (alone). Drops the post-prandial dietary sense which is the whole of Su.Su.46 and most of Ca.Su.27.
  • post-prandial drink (alone). Drops the medicine-vehicle sense Kaviratna's footnote and the Chikitsasthana usage attest.
  • sedative (Kaviratna for tarpayati). Edwardian 'sedative' = soothing; not a CNS depressant claim.

Open questions

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

  • Kaviratna's printed numbers in the Su.27 anupana block are OCR-damaged; read the scan to record them.
  • Sanskrit verse numbers for the Su.Su.46 anupana section (a search result cited 46/367-383 for various lines but this was not verified).
  • Whether any trial has isolated anupana as an independent variable: none found in the searches run.
