Auriculotherapy is a clinically effective treatment modality utilized for the relief of chronic pain and the alleviation of substance abuse. The external ear has been shown to have a somatotopic organization in an inverted fetus pattern, wherein each part of the auricle corresponds to a specific part of the body.  Detection of electrical conductance and tenderness palpation can reveal specific auricular reflex points which can be stimulated to alter pathological reflex patterns in the brain, in internal organs, and in different peripheral regions of the musculoskeletal body.

Auriculotherapy is the stimulation of the auricle of the external ear for the diagnosis and treatment of health conditions in other parts of the body. It is also known as ear acupuncture or auricular acupuncture when the stimulation is achieved by the insertion of acupuncture needles, whereas the term auriculotherapy often refers to electrical stimulation of the surface of ear reflex points. Specific points on the ear can also be stimulated by manual pressure, referred to as auricular acupressure or ear reflexology. Acupuncture points on the ear can also be stimulated with lasers, magnets, and ear seeds.

Auriculotherapy is considered one form of alternative medicine, which also includes acupuncture, chiropractic manipulation, homeopathy, and biofeedback. All of these techniques are also referred to as Complementary Medicine, in that they are not only an alternative to conventional Western medical treatments, they can serve as an additional procedure which complements the practice conventional medicine. Auriculotherapy can reduce the tension, stress, and pain not fully relieved by other medical procedures, but works best when implemented as part of a multidisciplinary complement of multiple treatment approaches. While ear acupuncture is often used in conjunction with body acupuncture, auriculotherapy can also effectively relieve pain, stress and tension when used by itself.
