The main function of Siguan point has been described in ancient medical books: "Xi Hongfu" "The pain in the hands, shoulders and spine is unbearable, and the acupuncture at Hegu point should be too dull"; "The Song of Miscellaneous Acupoints Method" includes "nasal congestion, epistaxis and nasosinusitis, so you can take Hegu Taichong at will". Hegu and Taichong points are compatible as Siguan points because Hegu and Taichong points are the original points of Shouyangming and Zujueyin respectively. The original point is the place where the original qi of meridians and viscera passes and stays, which is closely related to the triple energizer. The primordial qi comes from the dynamic qi between the kidneys, which is the motive force of human life activities and runs through the triple energizer, and is the foundation of the twelve meridians. Therefore, the original point is an important point to regulate the body's gasification function. "Su Wen Tiaojing Lun" says: "Man's master is blood and qi." Human activities can not be separated from qi and blood, and when pathological changes occur, it is nothing more than qi and blood, and qi is the handsome of blood, and blood is the mother of qi. The main mechanism of acupuncture, shiatsu massage and cupping in treating diseases is to regulate human qi and blood through meridians.
"Table Friends Fu" says: "The pain of cold and heat has just started level 4." Obstruction and stagnation of qi and blood are mostly caused by wind, cold and dampness, blocking meridians. The four passes are the main roads for qi, blood, yin and yang to pass in and out from the outside, and they should be unobstructed. If exogenous evil invades, the four channels are closed, the channels are blocked, and the circulation of qi and blood is blocked, arthralgia syndrome becomes arthralgia syndrome. The main symptoms of arthralgia syndrome are pain and motor dysfunction, but it can be divided into joint pain, joint pain, joint pain and heat arthralgia due to different exogenous pathogens. Clinically, such as disc herniation, rheumatoid arthritis, rheumatoid arthritis, joint degenerative diseases and so on. Siguan point can be used to dredge meridians, relieve arthralgia and relieve pain.
