In classical Chinese medicine, the ear is considered an extraordinarily powerful nexus of energy through which the entire body can be treated. There are over 100 or so separate acupuncture points on the external ear and that when these points are stimulated they are believed to influence the various organs and systems in the body.
As with all forms of acupuncture, the acupuncture points found in the outer ear correspond to other locations in the body. By stimulating these points, the acupuncture needle sends electrical impulse messages to the brain, which are then thought to stimulate other areas of the body. In this way, auricular acupuncture can relieve pain in the joints and muscles, stimulate the organs and the brain itself, and achieve a number of other therapeutic effects for the patient.
