Ayurveda is the world’s third great constitutional medicine, alongside the Chinese and Western traditions. Its system of doshas, Vata, Pitta and Kapha, describes individual terrains; its dietetics organises food by the six rasas (flavours); its concept of agni (digestive fire) is the direct Indian equivalent of the Chinese digestive Fire. Comparing the systems illuminates each.
Ayurveda: the Vedic medicine of terrain
Ayurveda (“science of life”, Sanskrit) is the traditional medicine of India, codified in the texts of the Charaka Samhita and the Sushruta Samhita (around 300 BCE to the first centuries CE). Its principle: health is the dynamic equilibrium of the doshas (functional energies), agni (digestive fire), dhatus (tissues) and malas (wastes). Diet is a pillar of the regimen, adapted to the terrain, the season and the time of day.
The three doshas: Vata, Pitta, Kapha
The doshas are formed from the five elements (ether, air, fire, water, earth) and govern functions.
Vata (air + ether) governs movement: breathing, heartbeat, nerve impulses, intestinal transit. The Vata person is thin, mobile, lively, irregular, cold, anxious when out of balance. Imbalances: constipation, insomnia, dryness, irregular pains.
Pitta (fire + water) governs transformation: digestion, metabolism, intellectual comprehension. The Pitta person is medium-built, warm, intense, clear-minded, determined, irritable when out of balance. Imbalances: acidity, inflammation, irritability, skin disorders.
Kapha (earth + water) governs structure and lubrication: tissues, immunity, cohesion. The Kapha person is sturdy, calm, stable, slow, smooth; when out of balance, congested and sluggish. Imbalances: overweight, mucus, slowness, attachment.
| Dosha | Elements | Function | Imbalance | Pacifying diet |

Agni, the Indian digestive fire
Agni is the digestive fire, the exact equivalent of what TCM calls the digestive Fire or the Fire of the Kidneys and the digestive function of the Spleen. Agni transforms food into usable substance; a weak agni produces ama (undigested matter, toxins), the Indian equivalent of Dampness and retained foods.
Ayurveda modulates agni by terrain, season and time (strongest at midday). Its practical rules (hot water, spices that light fire, regular meals, no snacking, early dinner) are astonishingly close to TCM’s recommendations. Two civilisations, one conclusion: digestion is a fire, and health depends on it.
The six rasas: Indian flavours
Ayurveda classifies foods into six rasas (flavours): sweet (madhura), sour (amla), salty (lavana), pungent (katu), bitter (tikta), astringent (kashaya). The system is close to the five flavours of TCM, but richer in detail (bitter and astringent separated, where TCM merges them). Each flavour acts on the doshas: sweet pacifies Vata and Pitta, increases Kapha; pungent stimulates Vata and Pitta, reduces Kapha, and so on.

FAQ: Ayurveda and diet
What is my dosha?
Everyone is a mixture of the three doshas, with one or two dominant (prakriti). Questionnaires exist; Ayurvedic consultation (observation, pulse, tongue) remains the reference. The dosha determines your ideal diet, your tendencies and your frailties.
Is Ayurveda compatible with TCM?
Yes, conceptually: both are terrain medicines with constitutional typologies, a central digestive fire, flavour-based dietetics and holistic hygiene. In practice, each has its own coherence: they can be read in parallel, not merged.
Is the Ayurvedic diet suitable for everyone?
It is designed to be adapted: no universal diet, but a diet by dosha, season and moment. Its rules (hot water, fresh food, cooked over raw, early dinner) suit most terrains, but the choice of foods depends on the individual dosha.
What is ama?
Ama is undigested matter produced by weak agni: the equivalent of TCM’s Dampness and retained foods. Signs: coated tongue, post-meal heaviness, lethargy, coated sensations. Ayurveda removes it by lighting agni (spices, fasting, warm water) and lightening the diet.
A third tradition to read alongside the Chinese one
Ayurveda confirms, from another civilisation, what TCM says: the terrain is individual, digestion is a fire, flavours have functions, and diet adapts to the constitution. Comparing Vata, Pitta and Kapha with Chinese patterns, agni with digestive Fire, ama with Dampness, is not a syncretism but a recognition: the great terrain medicines converge.
