A dosha is one of three bodily humors that make up one's constitution according to Ayurveda. These teachings are also known as the Tridosha system.
The central concept of Ayurvedic medicine is the theory that health exists when there is a balance between three fundamental bodily humours or doshas called Vata, Pitta and Kapha.
All Ayurvedic physicians believe that these ancient ideas, based in the knowledge discovered by the Rishis and Munis, exist in harmony with physical reality. These Ayurvedic concepts allow physicians to examine the homeostasis of the whole system. People may be of a predominant dosha or constitution, but all doshas have the basic elements within them. There are 5 types of pitta dosha 1) Pachaka 2) Ranjaka 3) Alochaka 4) Sadhaka 5) Bhrajaka.
