The acupuncture point is one of the more commonly used points in various disciplines. The Ming Dynasty’s “Acupuncture and Moxibustion” states that the acupuncture point is on the tip of the ear, which is taken by rolling the ear. This point is easy to use and has good therapeutic and auxiliary effects on many common diseases and some difficult diseases, and often shows miraculous effects on some acute symptoms. Modern research has shown that the ear-tip point has “three anti”, namely anti-allergic, anti-inflammatory, anti-rheumatism, can enhance the body’s immune function. The use of blood pricking at the ear tip can promote blood circulation, improve blood and oxygen supply to tissues, and enhance the immune function of the body. Ear-tip bloodletting can quickly and obviously improve the main clinical symptoms of hypertension with hyperactivity of liver and yang, and has a good immediate effect on lowering blood pressure; it can remove blood stasis and unblock blood vessels, and has a significant effect on lowering total cholesterol, triglycerides and low-density lipoprotein in serum; it can stop atherosclerosis and slow down the occurrence of coronary heart disease; it can improve the functional state of cerebral blood vessels, increase cerebral blood flow and improve cerebral vascular elasticity. In summary, it has six main functions: antipyretic, anti-inflammatory, sedative, analgesic, antihypertensive, anti-allergic, brain-clearing and eye-opening, as well as regulating the functions of internal organs, transmitting biological information, enhancing immunity and promoting cell metabolism. The most commonly used pricking method for ear-tip acupuncture points is pricking therapy, and there is still a folklore tradition of bloodletting from ear-tips to treat ophthalmic diseases such as mydriasis, keratitis and conjunctivitis. There are also people who take blood from the ear tip, Shuxuan, Renzhong and Zhizhong to treat children with high fever that does not subside and the fever increases, and those who are in a hurry have remarkable results. For patients with neurasthenia, insomnia and women with menopausal syndrome, auricular pressure pills together with auricular bloodletting can regulate cerebral cortex function and treat palpitations, insomnia and irritability with definite effect. Ear-tip blood pricking combined with auricular pressure is more commonly used for acne, urticaria and other skin diseases. This method can also be used to relieve spasm, analgesia and anti-infection, and to relieve pain in various types of pain, such as acute cholecystitis, cholelithiasis, severe headache, mumps and toothache. Ancient people used to massage the ear as an important means of health care, and nowadays ear massage is becoming more and more recognized. Stimulating the relevant ear points can promote blood circulation through various transmission pathways and regulatory functions, adjust cellular functions, improve the body’s immunity, so that the body’s physiological functions and internal environment tend to be benignly regulated, thus achieving the purpose of health care. For example, the method of lifting the tip of the ear, using the thumb and fingers to lift the top of the ear more than 10 times, can regulate sleep, blood pressure, emotions, clear the brain, brighten the eyes, and lower the blood pressure effect.
