"Ayurveda as the name implies ('Ayu': "life" and 'Veda':knowledge) is the knowledge of healthy living and is not confined only to treatment of illness. It is widely practiced in India and caters to the needs of nearly 75% percent of the population. The pharmacopeia of Ayurveda is a rich heritage of herbal practices describing medicinal uses of over 600 plants in seventy books containing 8,000 recipes of drug combinations."
