In Traditional Chinese Medicine (TCM) the ear is an important organ having many points on it corresponding to the body systems and it is said that all the main meridians are crossing the ear. It is a microcosm of the macrocosm: the ear represents the entire body. The ear represents a fetus in the womb but in an inverted position.

According to WHO, auricular therapy can be used in the treatment of addiction, whether to drugs, alcohol, food or tobacco. Clinical trial has not yet been able to verify its effectiveness Auricular acupuncture may be effective in treating arthritis, asthma, indigestion, migraine, urinary problems and nervous disorders.

By stimulating a special area of the ear certain body parts are being activated through various nerve pathways. By stimulating the hypothalamus (the area of the brain containing the appetite control center and the vagus nerve) auricular point, hunger is curbed and digestive secretions reduced. The vagus nerve communicates with the taste buds and salivary glands to alleviate hunger and it gives a feeling of being satiated. You are creating a somatic 'body' response in the corresponding body parts.
