Auriculotherapy is typically considered one form of acupuncture.
The basic concept in auriculotherapy is that nerves in the skin overlying specific areas of the external ear correspond to specific parts of the brain which has reflex connections to the body.
Cutaneo-Organic Reflexes are activated when specific points on the auricle are stimulated in order to relieve organic pathology in another part of the body. Points on the ear can also be stimulated by manual pressure through ear seeds or magnets.
Auriculotherapy is used as control of chronic pain, detoxification from addictive drugs, relief of nausea, reduction of hypertension and more.
