More than a medical system, Ayurveda means the "science of life," and is central to the culture of India. Ayurveda does not focus on the disease but rather on keeping a person healthy. Quite probably the oldest and most complete medical system in the world, it dates back to 3000 BC. Historical evidence of Ayurveda can be found in the ancient books of Indian wisdom known as the Vedas. Its development greatly influenced all other Oriental medical systems.

Much like Chinese medicine, Ayurveda views a human being as a microcosm of the universe. If the "life force," or "prana" is unbalanced, disease follows. Three forces, or "doshas," determine the proper balance of prana. They include Pitta, the force of heat and energy; Kapha, the role of water and tides; and Vata, linked to the wind. Their subtle alignment to mind, body and spirit produce health. To maintain the body’s equilibrium, dietary changes, yoga, meditation, herbs, massage and possibly chanting will be recommended. These lifestyle suggestions are always unique to the individual.

Ayurvedic medical practitioners are not licensed in the U.S. Those who practice this specialty must be accredited in medicine, chiropractic, nutrition or another health-care field. Training is available at Ayurvedic institutes.
