Objective,2,To summarize Professor WU Shengyuan's experience on treating myoarthralgia.,Methods,2,Through the summary of professor WU Shengyuan's clinical diagnosis and treatment of myoarthralgia, the characteristics and common evidences of clinical prescriptions in myoarthralgia treatment were analyzed.,Results,2,Professor WU Shengyuan believes that the basic pathogenesis of muscle arthralgia is that the deficiency of vital Qi can not resist the evil. The evils of wind-cold, dampness and heat invade the muscle, stagnate in the muscle joints, obstruct the veins and the blood flow is not smooth, resulting in skin erythema and local muscle joint pain. At the early stage, the mainmethod is to dispel pathogenic factors, supplemented by strengthening the vital Qi, and regulate and supplement lung and spleen. In the later stage, we should focus on strengthening the body and eliminating pathogenic factors, and pay attention to tonifying liver and kidney. Spleen is the main factor of Zang-Fu syndrome differentiation and dampness is the main cause of syndrome differentiation based on causes. In the treatment of muscular arthralgia, we should pay attention to the transformation of excessive evil Qi, verify and investigate the causes, and eliminate the evil first. It is emphasized that kidney and spleen-stomach should be paid attention to and the spleen and stomach should be regulated throughout the treatment. According to clinical experience, it can be divided into wind-heat injuring lung syndrome, cold-dampness obstructing syndrome, dampness-toxin transforming heat syndrome, Qi deficiency and blood stasis syndrome, Qi and blood deficiency syndrome, upper heat and lower cold syndrome and Yang deficiency of spleen and kidney syndrome.,Conclusion,2,Professor WU Shengyuan's experience on treating myoarthralgia has proved clinical effect and is worthy of learning.
