Abstract

The invention relates to a pharmaceutical composition with liver-protecting effects. The composition comprises the following substances by weight: 6-15 parts of black tea polyphenol and 2-6 parts of a Silybum marianum extract. The silymarin and black tea polyphenol with different drug effects have very clear roles in prevention and treatment of chemical liver injury from different targets and the ways of, and are complementary with each other to effectively prevent and treat chemical liver injury. The two medicines are combined to perform the efficacies of strengthening and nourishing the liver, coursing the liver, detoxifying and immunoloregulation. Tests have proved that the pharmaceutical composition provided by the invention can prevent liver injury.

Description

technical field [0001] The invention relates to a pharmaceutical composition with hepatoprotective effect and a preparation method thereof. It belongs to the field of medicine and food. Background technique [0002] The liver is the largest gland in the human body. It plays a very important role in human metabolism, bile production, detoxification, blood coagulation, immunity, heat production, and regulation of water and electrolytes. Generally speaking, there are two main pathogenic factors that cause liver damage. One is liver inflammation caused by pathogenic microorganisms such as virus infection, such as hepatitis A and hepatitis B. The other type is chemical liver damage, which is liver damage caused by chemical hepatotoxic substances. As an important detoxification organ of the human body, the liver has dual blood supply from the hepatic artery and the hepatic vein. Chemicals can enter the liver through the portal vein of the gastrointestinal tract or the systemic ...
