Ten-Xuan bloodletting therapy in traditional Chinese medicine refers to ten acupoints located in the middle of ten finger tips, which are called ten-Xuan acupoints. Then puncture Xuan Shi point with a triangular needle to release a small amount of blood and expel toxins from the human body, so as to achieve the purpose of treating diseases. This method is called Xuan Shi bloodletting. It has the effects of relieving swelling and pain, expelling wind, relieving itching, inducing resuscitation, relieving fever, stopping vomiting and diarrhea, dredging channels and activating collaterals. For example, in the first aid of stroke, the patient's finger should be pricked with the ten-announcement bloodletting method, and bleeding should be caused (in case the blood does not come out, it can be squeezed by hand). After bleeding from ten fingers (one drop per finger), the patient naturally wakes up in a few minutes. If the mouth is crooked, pull his ear and turn it red. Two needles in the earlobes of both ears will shed two drops of blood. After a few minutes, the mouth will return to its original state. When the patient returns to normal and feels normal, he can turn the corner. Otherwise, if he is rushed to an ambulance for medical treatment, I'm afraid he won't get to the hospital all the way, and his brain capillaries will burst.
