The classical medical tradition of the Indian subcontinent, whose Sanskrit name means "the science of life" (ayus, life, and veda, knowledge). Rooted in the late Vedic world and systematized in great compendia such as the Charaka Samhita and the Sushruta Samhita, it holds that health is the balance of three bodily humors, the doshas, and treats imbalance through diet, herbs, lifestyle, oil therapies, and purification. One of the world's oldest organized medical systems and a genuine ancient achievement, it is also a booming global wellness industry whose specific therapeutic claims mostly lack robust clinical support, and some of whose traditional metal-based preparations have caused heavy-metal poisoning.
Two thousand years ago, a surgeon working in the tradition that became Ayurveda could rebuild a human nose. He cut a flap of skin from the cheek, turned it down over the wound, and shaped a new nose where one had been cut away as punishment or lost to disease. The technique is described in the Sushruta Samhita, an ancient Indian medical text, and modern reconstructive surgery still echoes it. This was not magic or guesswork. It was careful, observed, teachable medicine, set down in a system that also mapped the body as a balance of forces to be kept in harmony. Ayurveda is that system: one of the oldest organized medical systems on earth, revered by hundreds of millions, and argued over by everyone who asks what it can actually cure.
