Auricular acupuncture is the stimulation of acupuncture points on the external ear surface for the diagnosis and treatment of health conditions in other areas of the body. The ear holds a microsystem of the body, consistent with the brain map discoveries of Canadian neuroscientist Wilder Penfield. Dr. Penfield found that maps of the body exist on the surface, or sensory cortex, of the brain. This same brain map is also projected onto different areas of the body, “microsystems”, and in particular precision, onto the ear. The introduction of lasers, especially low-level lasers into medicine brought besides the already existing stimulation with needles and electricity an additional technique to auricular acupuncture.
Ear acupuncture is used to improve the body's flow of vital energy (also known as chi or qi) and to restore a balance between yin and yang (two opposing but complementary energies) within the internal organs. In traditional Chinese medicine, each of these effects is considered essential in treating disease and achieving health.
Auricular acupuncture is typically used for these and other health conditions:
