what is ayurveda?

its history 
Ayurveda is the oldest medical system for disease prevention and health promotion, and also provides treatment for disease in an always personalised way. It is a 5,000 years old system of natural health-giving that has its origins in the ancient books of wisdom known as the Vedas, a profound part of Indian culture. We can find historical evidences in the Rig Veda or the Atharva Veda, where over 60 preparations were mentioned which could be used to assist individuals in overcoming various ailments. 

Tibetan medicine and traditional Chinese medicine both have their roots in Ayurveda. Early Greek medicine similarly incorporated many concepts originally described in the classical Ayurvedic medical texts dating back thousands of years.
