Tibetan medicine is rich and colorful, and many of its unique treatment methods reflect strong ethnic characteristics and are still widely used. Tibetan medicine bloodletting therapy is a relatively drastic surgical treatment. By cutting or puncturing blood vessels, bloodletting is performed to draw out the diseased blood from the body to achieve the purpose of treatment. Tibetan medicine bloodletting therapy is mostly suitable for febrile diseases, such as plague, furuncle, sore, erysipelas, yellow water, leprosy, diffuse heat injury, and hot fever. However, some diseases are not suitable for bloodletting therapy, such as deficiency and cold diseases such as exhaustion of positive essence, gray edema, and decline of stomach fire, as well as children, the elderly, pregnant women, and postpartum women. Bloodletting is contraindicated. According to the type of disease and the course of the disease, it can be roughly divided into three stages: early, middle and late stages for treatment. In the early stage of all febrile diseases, bloodletting should be performed in time when the fever begins and the heat is hyperactive. In the middle stage of the course of the disease, when the aversion to cold stops and the body feels numb and heavy, bloodletting should be performed in time to release the bad blood to prevent the heat from spreading and becoming difficult to control. In the process of blood disease and Tripa disease, the diseased blood has spread in the meridians, or due to improper diet, there is residual heat that has not been eliminated, which has spread in the meridians. Although it is in the late stage, it can also be treated with bloodletting. The Tibetan medicine bloodletting process is divided into the steps of beating the pulse, inserting the knife, observing the blood, and mastering the amount of bleeding. The so-called beating pulse method is to try to make the blood flow vigorous. This requires taking some decomposing medicines such as Sanguo Decoction (composed of Terminalia chebula, Terminalia chebula, and Phyllanthus emblica) orally three days before bloodletting. The purpose is to separate the diseased blood from the normal blood. The body should be warmed before bloodletting. When the blood flow is vigorous, use a flat string to tie the above parts of the bloodletting. The acupuncture points for bloodletting are fixed, and the vital parts and lifeline parts should be avoided. During bloodletting, if the outflowing liquid is yellow and thin, or even has foam or mucus, it is diseased blood. If the released blood is bright red and thick, it is normal blood and cannot be released again. As for how much bloodletting is appropriate, it also depends on the condition and the patient's condition. Generally, patients with stronger constitutions can be given slightly more bloodletting. Once the diseased blood has been drained and the normal blood appears, the bloodletting should be stopped. Do not bleed too much to avoid damaging the positive energy.
