Yangxi is located at the wrist, in the anatomical “snuffbox” depression. It can be used to treat wrist pain, headaches and other conditions. Yangxi is a point on the Large Intestine Meridian, which is located in the wrist area, at the distal end of the radial tuberosity, on the radial side of the dorsal distal transverse stripe of the wrist, in the anatomical “snuff fossa” depression. There is the cephalic vein, the radial artery trunk and its dorsal wrist branch, and the superficial branch of the radial nerve, between the tendon of the extensor hallucis longus and the tendon of the extensor hallucis brevis. Yangxi is used for treating wrist pain, headache, redness and swelling of the eyes, deafness, and other diseases of the head and face. Please do not perform acupuncture or other operations on this point on your own to avoid adverse reactions. If you feel unwell, please go to the hospital as soon as possible and be treated by a professional doctor.
