Since Ayurveda is really the generic term for "traditional medicine" in India, actual practice may be widely divergent. Descriptively, one may either focus on the historical foundation from the evidence of the earliest ayurvedic texts of the early centuries of the Common Era, or alternatively a description may take an ethnographic approach and focus on the forms of traditional medicine prevalent across India today.
Much like the medicine of classical antiquity, Ayurveda has historically taken the approach of enumerating bodily substances in the framework of the five classical elements (Sanskrit [maha]panchabhuta [, earth water, fire, air and aether), considering the seven "tissues" dhātu (Devanāgarī: saptadhatu सप्तधातु of plasma (rasa dhātu), blood (rakta dhātu), flesh (māṃsa dhātu), adipose (medha dhātu), bone (asthi dhātu), marrow (majja dhātu), and reproductive (śukra dhātu).[11]

Each person has a natural systems state, or natural combination of the three elements, and should seek balance by structuring their behavior or environment to provide more of the element(s) they lack.[12] Another view, also present in the ancient literature, asserts that humoral equality is identical to health, and that persons with preponderances of humours are proportionately
