The meridians on the back of the body are mainly the Governor’s meridian and the bladder meridian on both sides of the spine. The body’s Yang meridian is the body’s Yang, so Gua Sha treatment for the Governor’s meridian can invigorate Yang energy and increase the body’s constitution, making it less likely to catch a cold. In addition, the bladder meridian on both sides of the body is also the innervation area for various organs of the body, so Gua Sha treatment of the bladder meridian can improve the function of the organs of the body and can treat diseases caused by various organs, such as heartburn caused by heart disease; shortness of breath caused by the lungs; abdominal distension, abdominal pain and diarrhea caused by dysfunction of the spleen and stomach; and water metabolism disorders caused by the kidneys, all of which can be treated with Gua Sha. Treatment, especially gua sha treatment on both sides of the bladder meridian, can improve the various symptoms caused by the above organs.
