Bloodletting is one of the external therapies in Chinese medicine. Jie Bone is the nickname for the Hang Zhong point on the foot-shaoyang bile meridian, where bloodletting is used to treat conditions such as strong neck pain and fullness of pain in the chest and ribs. Bloodletting therapy is the use of three-pronged needles to puncture specific areas, releasing some of the blood in the body to achieve the purpose of treating diseases. The Jie Bone point is a nickname for the Hang Zhong point, which belongs to the foot Shaoyang bile meridian and is located on the outer side of the lower leg, 3 inches above the tip of the ankle, at the anterior edge of the fibula. Bloodletting at this point can be used to treat strong neck pain, fullness of pain in the chest and hypochondrium, stroke and dementia, and impotence and paralysis of the lower limbs (lower limb weakness, numbness and pain) and other conditions. When using bloodletting therapy, it should be noted that it is not suitable for patients with broken skin, infections and bloodsickness. If you need to use bloodletting therapy, it is recommended to go to a regular hospital for consultation and treatment under the guidance of a professional physician.
