Hegu is located at the midpoint of the radial side of the 2nd metacarpal bone, and Taichong is located at the union of the 1st and 2nd metatarsal bones on the back of the foot. Siguan point has the effect of calming the liver and yang, regulating qi and blood, and is used to assist in the treatment of cold and dampness, paralysis and pain and other diseases. The Siguan acupoint consists of two main points, one is the Hegu acupoint and the other is the Taichong acupoint. The Hegu point is located mainly on the back of the hand, between the 1st and 2nd metacarpal bones, at the midpoint of the radial side of the 2nd metacarpal bone. The Taichong point is located mainly on the metatarsal bones, in the depression on the dorsum of the foot where the 1st and 2nd metatarsal bones come together. The main effects of Siguan point are to calm the liver and yang, regulate qi and blood, and dredge the meridians and collaterals, etc. It is generally used as an adjunctive treatment for cold and dampness, paralysis and pain, chilling of the limbs, hoarseness of voice, and restlessness of the mind. The two points of Si Guan acupoints are located at the back of the hand and metatarsal bones, which can regulate qi and blood, dredge meridians and collaterals, but can not be used for the main treatment of the disease. It is recommended that patients massage or acupuncture the Si Guan acupoints with the help of a professional doctor, and should not do it on their own.
