In auricular medicine, the posterior of the ear images the posterior of the body. Many of the points in this region have a functional equivalent on the front of the ear. The four areas on the posterior ear are primarily used for diagnosis: Gallbladder Area, Duodenum Area, Dream-Disturbed Sleeping Area, and Tumor Specific Area 1 Posterior. The other points and grooves can be used for treatment, mainly for problems on the back of the body. For severe conditions, Dr. Huang would "sandwich" a point by seeding from both the back and front of the ear to strengthen the treatment effect with intensified stimulation at the point.
