Ear points are acupoints distributed on the auricle. When the body’s internal organs or torso is ill, local reactions such as pressure pain, nodules, discoloration, and electrical conductivity often appear in certain parts of the auricle. This phenomenon can be used as a reference to diagnose diseases or to stimulate these reaction points (auricular points) to prevent and treat diseases. The ear has a close relationship with the internal organs and meridians, and all internal organs and tissues have corresponding reaction areas (ear points) in the auricle. Stimulation of ear acupuncture points can have certain therapeutic effects on the corresponding internal organs. Ear acupuncture is a method that uses adhesive tape to stick Wang Bu Liuxingzi to the corresponding ear points in order to produce soreness, numbness, swelling, pain and other sensations by pressing the ear points with hands. This method is easy to operate and has obvious curative effects. It has the effect of dispelling wind and clearing the channels, removing stasis and relieving itching. It is often used for diseases such as chloasma, acne and obesity caused by endocrine disorders, as well as for urticaria, neurodermatitis and pruritus. According to the holographic meridian theory of Chinese medicine, the ear has a close relationship with the internal organs and meridians of the human body. For example, the ear is connected to the meridians: hand Shaoyang meridian from behind the ear out of the upper corner of the ear, branch veins into the ear; foot Shaoyang meridian down behind the ear, branch veins to the ear, out of the front of the ear; hand Sun meridian into the ear; foot Yangming meridian on the front of the ear; branch veins of the foot Sun meridian to the upper corner of the ear; hand Yangming other meridians into the ear. Hand and foot three Yang meridians are all tied to the ear, Yin meridians through the meridian to merge in Yang meridians and the ear. Among the eight channels, the yin and yang stilt channels enter the ear, and the Yang Wei channel follows the head and enters the ear. The ear is connected to the internal organs by the Kidney Qi, the Liver Qi, which is deaf and deafening, and the Lung Qi, which is deafening. There are five main methods of matching ear points: 1) by holographic meridians; 2) by visceral identification; 3) by modern medical theory; 4) by corresponding parts; 5) by ancient and modern clinical experience. In clinical treatment, we choose the appropriate point allocation method according to the theory of Chinese medicine to prevent and treat related diseases.
