Who discovered Acupuncture?

Acupuncture is a discovery of Chinese of years. It is a kind of medical treatment which involves the insertion of needles at various points on the body. The Taoists believed that the body depends on two opposite states called Yang and Yin, and the imbalance between them caused illness. By using acupuncture the balance between these two states was restored. The length of needles to be inserted ranges between two and twenty five centimeters. They are inserted at one or more points lying along certain line of the body. The practice is still in use and surgery is often performed by acupuncture instead of anaesthetics.
