Ayurveda: India's traditional, natural system of medicine that has been practiced for more than 5,000 years. Ayurveda provides an integrated approach to preventing and treating illness through lifestyle interventions and natural therapies. Ayurvedic theory states that all disease begins with an imbalance or stress in the individual's consciousness. Lifestyle interventions are a major ayurvedic preventive and therapeutic approach. There are ten ayurveda clinics in North America, including one hospital-based clinic that has served 25,000 patients since 1985.

In India, ayurvedic practitioners receive state- recognized, institutionalized training in parallel to their physician counterparts in India's state-supported systems for conventional Western biomedicine and homeopathic medicine. The research base is growing concerning the physiological effects of meditative techniques and yoga postures in Indian medical literature and Western psychological literature. Published studies have documented reductions in cardiovascular disease risk factors, including blood pressure, cholesterol, and reaction to stress, in individuals who practice Ayurvedic methods.

Laboratory and clinical studies on ayurvedic herbal preparations and other therapies have shown them to have a range of potentially beneficial effects for preventing and treating certain cancers, treating infectious disease, promoting health, and treating aging. Mechanisms underlying these effects may include free-radical scavenging effects, immune system modulation, brain neurotransmitter modulation, and hormonal effects.
