Ayurveda was originally a Hindu medical system which had its beginning more than 2,500 years ago in the sixth century B.C. It was adapted by Buddhists and other religious groups and has recently undergone a rebirth in India and throughout the Western world where it is considered a viable alternative to pharamaceutically based western medicine.
Ayurveda is a humoral medical model. The humors are defined as air, bile, phelgm, and blood. Ayurveda postulates that most humans are born in humoral balance but soon loose this balance due to unbalanced diet, unbalanced emotional experiences, or traveling away from the physical location on the earth which is most in harmony with his or her constitution.
The primary means of returning to humoral balance is diet. While Ayurveda has general recommendations for diet which anyone can follow for optimal health, more serious illnesses are treated by a qualified Ayurvedic physician. This type of physician is required to take at least seven years of training in Ayurvedic medicine and will recommend a finely tuned diet and other methods to return humoral balance.
