In the Five Elements, the liver is wood and the spleen is earth. In the physiological state, liver wood restrains spleen earth. In the pathological state, when the spleen is weak or the liver is strong, and the wood is too strong for the earth, a series of uncomfortable symptoms will appear. In Chinese medicine, it is said that “the spleen does not suffer from evil in all seasons”, on the contrary, when the spleen is weak, it is easy to be multiplied by the liver wood; when the liver qi is depressed and the liver wood is not sparing, it will also excessively subdue the spleen and the soil. Common clinical manifestations include loss of appetite, failure to eat, abdominal distension and pain, discomfort in the abdomen and ribs, belching (burping) and acid reflux, bowel disorders, frequent sighing, etc. Clinically, the liver and spleen are closely related. Clinically, the liver and spleen are closely related, physiologically interconnected and pathologically interacting, and are often regulated at the same time, e.g., commonly used classical prescriptions such as Xiao Chai Hu Tang and Free and Easy San. If there is any discomfort, consult a doctor in time, do not use medication without authorization, so as to avoid adverse consequences.
