Auriculotherapy is a form of alternative medicine involving stimulating points on the outer ear to treat pain and health conditions throughout the body. It originated in ancient China, Egypt, Greece and other cultures and was further developed by Dr. Paul Nogier in the 20th century. Auriculotherapy treatments are non-invasive and involve techniques like acupressure, acupuncture, or electrical stimulation of specific points on the ear to relieve symptoms. Common uses include treating addiction, pain, mental health issues, and internal disorders.
