Quze and Shakuzawa are located in the elbow area and have relatively distinct body veins that can be treated with bloodletting using three-pronged needles. Quze is an acupoint of the pericardium meridian of the syncopal meridian of the hand, located in the center of the transverse stripe of the elbow in the depression of the ulnar border of the biceps muscle. Shakuzawa is an acupoint of the Hand Taiyin Lung Meridian, located in the center of the transverse stripe of the elbow, in the depression of the radial margin of the biceps. Both of these points have distinct body veins, and bloodletting involves puncturing the point with a three-pronged needle, a method known as stabbing and bleeding, which releases a small amount of blood or body fluid to treat the disease. Both Qu Ze and Shak Ze can be used to treat acute abdominal pain and diarrhea, heat stroke, fever and other diseases. When carrying out bloodletting treatment, it is necessary to do a good job of disinfection, pay attention to the aseptic operation, and the amount of bloodletting needs to be decided according to the specific conditions of the disease and the patient’s physical condition, so do not let out too much blood. If you need to carry out bloodletting treatment, you need to go to a regular hospital, do not operate on your own, so as not to cause damage to the body.
