The emergence of different schools of
Sanskrit philosophy like
Nyaya,
Vaiseshika,
Sankhya,
Yoga,
Vedanta and
Mimamsa was another landmark in the history of the science of Indian medicine and health. The principles expounded in these philosophies facilitated the development of
Ayurveda’s theory of humoral pathology which propounds that the human body is composed of Trisdoshas – the three humors –
Vata,
Pitta and
Kapha. The
Tridosha in equilibrium are called the Tridhatu. The body in which these three humors are in state of equilibrium enjoys perfect health; their disequilibrium causes ill health.
