Silymarin capsules are not antiviral drugs and belong to the class of drugs that protect the liver. Silymarin has no direct effect on the virus and is not an antiviral drug. Hepatitis B and C patients can also use silymarin capsules as an adjunct to liver-protecting treatment along with antiviral therapy. Silymarin is a hepatoprotective drug, which can stabilize the liver cell membrane, remove free radicals in the body, protect the liver enzyme system, and can improve the detoxification ability of the liver, so it has a therapeutic effect on the elevation of aminotransferases caused by various types of hepatitis. It can be used for liver-protecting treatment of acute hepatitis, fatty liver, chronic hepatitis and other diseases. Liver diseases are recommended to be treated with medication under the guidance of a doctor, and attention should be paid to the adverse drug reactions during treatment.
