The theory of liver and spleen was proposed by Professor XIE Jingri， a scholar of Longjiang medical school.Theory of liver and spleen emphasizes that qi and blood are the basic substance of life，that qi and blood in coordination is the p re m is eof health，and that Five-zang organs have different influence on the nature and nurture of human life.As Zang-organs of acquired constitution，liver and spleen are not only the key to regulating qi and blood，but also the key to maintaining normal function in other Zang-fu organs.When the disease occurs，the liver and spleen should be the first to shoulder the responsibility，and in the occurrence of acid related diseases，there is an understanding that"no depression，no acid related diseases".In the treatment of diseases，the key should be focused on restoring the function of liver and spleen，and therefore the treatment should emphasize on the theory of"treating liver in acute condition，treating spleen in chronic condition and treating liver and spleen together"and the theory of"applying regulation rather than supplementation".
