The human liver is like the gas rising in spring, which has the characteristics of smoothness, patency and dredge. Liver-qi stagnation will not be discharged. According to the theory that the five elements coexist, it is called liver depression and fire.
In the physiological state of stomach inversion, the excretion function of the liver can promote the transportation of the spleen and stomach, and the transportation function of the spleen and stomach can help the liver to excrete. Wood can sparse soil and soil can enrich wood, which are interdependent and coordinated with each other. In the case of diseases, they also interact with each other, such as: depression hurts the liver, the liver loses the function of dispersing qi, the stomach goes against the wind, and the stomach is out of harmony, resulting in the syndrome of liver-qi invading the stomach; First, the stomach qi is insufficient, and the liver qi is relatively abundant, and then multiplied by the spleen and stomach, which can also cause the syndrome of liver qi invading the stomach. The former takes soil as Wang Mu, while the latter takes soil as virtual wood. Both the syndrome of liver-qi invading the stomach and the syndrome of disharmony between liver and spleen are caused by liver-qi invading the middle energizer, and both of them may have clinical manifestations such as chest pain, mental depression or irritability. However, the spleen governs transport and transformation, and its qi governs ascending; Stomach governs reception, while qi governs descent. Therefore, the syndrome of liver-qi invading the stomach is often accompanied by abdominal distension and pain, hiccups and belching, noisy acid swallowing, vomiting and other symptoms. However, the syndrome of disharmony between liver and spleen is manifested as loss of appetite, abdominal distension, loose stool and other spleen disorders.
