The emergence of different schools of Sanskrit
philosophy like Nyaya
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
. 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.
