Abstract

The invention discloses an application of methylidyne artemisinin in preparation of a medicine for treating liver diseases. The methylidyne artemisinin is combined with a medicinal carrier to form a medicine preparation, such as dripping pills, tablets, powders, capsules, granules, injections, microcapsules, syrups or oral solutions. The methylidyne artemisinin can reduce serum ALT, serum AST and liver index of liver disease patients, can improve functions of liver, effectively relieves liver damage due to alcoholic liver and hepatitis, can significantly reduce contents of HA, PC III and IV-C in patients and has significant anti-liver cirrhosis effect. The invention develops clinical application range of the methylidyne artemisinin and finds novel medicine sources for treatment on liver diseases, such as the alcoholic liver damage, acute liver damage, liver cirrhosis and the like, and also has advantage on complete utilization of the methylidyne artemisinin.
