In Ayurveda your body constitution is called your 'prakruti'. Each person's prakruti is composed of three body humours, or dosha, called Vata, Pitta and KaphaThese represent a combination of the elements - water, air, fire, earth and so on - that, according to Ayurveda, make up the human body. Each dosha is responsible for different functions and parts of the body so we each have all three dosha, although one or maybe two usually dominate.
