However, those who do not experience relief or worsening of symptoms after 2 weeks of use should consult a doctor promptly. Chai Hu Shu Hepatosan has the effect of dredging the liver and regulating the stagnation of liver qi (regulating the stagnation of liver qi), activating blood circulation and relieving pain (relieving pain by removing blood stasis). It is used for treating the symptoms of Liver-Qi stagnation (the lack of smooth flow of Liver-Qi). Symptoms include pain in the ribs and wounds, tightness in the chest, depression and irritability, belching (hiccups), distension and fullness in the epigastrium (abdomen), and a stringy pulse.
