Ayurveda is the system of traditional medicine prevalent in India since 2000 B.C. Ayurveda means the "science of life". Ayurveda derives medicine from Nature. After thorough study, experimentation and documentation of hundreds of plants over a period of more than a thousand years, India's ancient sages have come to accurate conclusions about the efficacy of different plants and herbs. Although efficacy of Ayurveda for a variety of human ailments is well known in and around India, most of the world is not aware of the benefits that could be derived from this unique Indian system of medicine. Most of the Ayurvedic preparations are free from side effects or reactions. Ayurveda provides rational means for the treatment of many internal diseases which are considered to be obstinate and incurable in other systems of medicine. Life according to Ayurveda is a combination of senses, mind, body and soul. So it is clear that Ayurveda is not only limited to body or physical symptoms but also gives a comprehensive knowledge about spiritual, mental and social health. Ayurveda describes three fundamental mind/body types or doshas, called Vata, Pitta and Kapha, which embody different combinations of the five elements : air, ether, fire, water and earth. When these elements are balanced, one is healthy. Illness is defined as an imbalance of these elements; all disorders are excesses of one or more element. Ayurveda is a form of treatment by natural remedies, which makes use of the power of nature to restore human beings to a state of balance.
