Tridosha

Tridosha ( त्रिदोष )

There are three biological humors or Doshas – Vata, Pitta, and Kapha. These control voluntary and physiological functions of body movements, and support the body in a normal and healthy state when in equilibrium. They are susceptible to impairment or imbalance. In an imbalanced state they may disturb structural and functional elements of living beings, causing disorders. Thus the Tridosha play an important role in the etiology, diagnosis and treatment of diseases.
