Chai Hu Shu Hepatosan is composed of Chen Pi, Chai Hu, Chuan Xiong, Xiang Fu, Citrus Aurantium, Paeoniae Alba and Glycyrrhiza Uralensis, and most of the medicines in the formula favor pungency and dispersal, and are therefore of a hot nature. Chai Hu Shuo Liver San is a traditional Chinese medicine formula from “Medical Unification”, which is a qi regulator. It has the efficacy of dispersing liver qi (regulating stagnation of liver qi), activating blood circulation and relieving pain (relieving pain by removing blood stasis). This formula is mainly used in treating the syndrome of Liver-Qi stagnation, which is characterized by pain in the ribs and wounds, tightness in the chest, depression, belching (hiccup), and distension of the epigastrium (abdomen). This formula is often used in treating chronic hepatitis, chronic gastritis, intercostal neuralgia, etc., which are caused by liver depression and stagnation of qi (poor circulation of qi and blood in the liver, and depression of mood). Note that this formula is aromatic, pungent and dry, easily depleting Qi and injuring Yin, so it should not be taken for a long time. The adverse effects of this formula are not clear, if you need to take this medicine, it is recommended to consult a medical professional.
