Acupuncture is an important component of the Chinese Traditional Medicine.Compared to the 3000 years of clinical practice,the extensive modern research on acupuncture is no more than half a century.In the late nineteen fifties,attempt was made to use acupuncture for the prevention of surgically induced pain in China and obtained limited success.This was tentatively termed"acupuncture anesthesia",which triggered the global interest of not only clinicians but also the basic biomedical researchers in the 1960s.
