Auricular therapy, ear acupuncture, and auriculoacupuncture) is a form of alternative medicine based on the idea that the ear is a micro system, 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 by several modalities, including the practices of reflexology and iridology.

Auricular therapy is a healthcare modality in which the external surface of the ear, or auricle, is stimulated to alleviate pathological conditions in other parts of the body. A channel of energy flow circles the body like meridians circle the globe. The goal of auricular therapy is to balance that energy flow, which runs the body and heals the body. Auricular therapy or ear acupuncture, is similar to acupuncture but concentrates on the ear.
