Auriculotherapy

Auriculotherapy - not to be confused with auricular therapy using needles (ear acupuncture) - is a form of alternative medicine based on the idea that the ear is a microsystem, meaning that the entire body is represented on the auricle (or auricula, or pinna - the outer portion of the ear) in a similar fashion to reflexology (zone therapy) and iridology (iridodiagnosis), and that the entire body can be treated by stimulation of the surface of the ear exclusively.
