The ear acupuncture treatment is the process of stimulating the acupuncture points present on the surface of the external ears for diagnosing as well as treating certain health conditions. The human ear comprises of a microsystem of the body. Dr Penfield, a neuroscientist is of opinion that maps of the whole body exist in the sensory cortex of the brain and is projected on various regions of the body, the ear being one part. The auricular acupuncture has proved to be one of the most effective means of treating a wide array of medical conditions in several parts of the body which may range from allergies to headaches to nervous disorders. The map present in the ear is in the pattern of an inverted fetus and comes with all the delicate details of the physiological, emotional and anatomical aspects of the body. The ear is the first human organ that that develops to its full size and becomes absolutely functional within 18 months of conceiving the baby. The auriculotherapy is particularly helpful as the ear is one of the few physical structures that is made up of 3 primary types of tissues, namely, mesoderm, endo and ecto in the developing embryo. The earliest record of an auriculotherapist dates back to ancient China but the recent development of the ear acupuncture treatment can be attributed to Dr Paul Nogier who was a neurologist by profession but was trained in acupuncture and its uses. This treatment, thus results in diagnosis and cure of several medical conditions.
