In Sanskrit, Ayur means 'pertaining to life' and Veda, 'science' or 'wisdom'. The philosophy of Ayurveda says that the theory of human pathology propounds that the human body is composed of Tridoshas, the three humours - Vata (air), Pitta (heat) and Kapha (water). The body in which three humours or Tridhatus are in a state of equilibrium enjoys perfect health and their disequilibrium causes ill health. The therapeutic aspect of this science focuses on regaining the perfect balance.Importance of physician in Ayurveda
