Auriculotherapy (also auricular therapy, ear acupuncture, and auriculoacupuncture) is a form of alternative medicine based on the idea that the ear is a microsystem, which reflects the entire body, represented on the auricle, the outer portion of the ear. Conditions affecting the physical, mental or emotional health of the patient are assumed to be treatable by stimulation of the surface of the ear exclusively. Similar mappings are used in many areas of the body, including the practices of reflexology and iridology. 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. Ear acupuncture has proven to be an efficient method of treating a wide variety of conditions, from headaches and allergies to addictions and pain disorders. Although acupuncture evolved in the context of Asian medicine, the specialty of ear acupuncture was developed in western Europe. It’s foundations laid by Dr. Paul Nogier, a neurologist working in France in the 1950’s, it was deepened and expanded by Frank Bahr M.D. and physical medicine specialists in Germany over the following decades.
