Ayurveda is an ancient Indian system of medicine that focuses on total health of body, mind and spirit. It is based on five elements - earth, water, fire, air and space - and three doshas or biological energies - vata, pitta and kapha. Everything in the universe is composed of combinations of these five elements, and a balance of the three doshas is necessary for health and well-being. Ayurveda also recognizes prakriti or constitutional types based dominance of particular doshas in a person.
