Chinese medicine believes that the internal organs and other parts of the body are closely connected to the auricle through the meridians, so it is said that “the ear is the gathering place of the clan and veins” and “the blood and energy of the 12 meridians and 365 veins all go up to the face and go to the orifices”. The purpose of ear acupuncture and ear acupuncture pressure is to promote the smooth circulation of the meridians, unblock qi and blood, promote the lung and remove turbidity, and reduce dampness and fat. Modern medicine believes that the nerves in the ear are rich in blood vessels, especially in the triangular fossa of the auricular cavity, and stimulating the nerves there has the effect of adjusting the imbalance of the body’s metabolism. In particular, stimulation of the vagus nerve can affect the insulin value and suppress appetite for weight loss. Psychologically, it is believed that this stimulation can make the patient feel dull in time. This is because the patient is free to resist the intention to eat more in order to break the habitual response that promotes the intention to eat and to begin to establish a new conditioned response to the signal to reduce the diet. This is psychologically supportive of weight control.
