Problems solved by technology

Practice has proved that there is currently a lack of ideal drugs for the treatment of AFL. Most of the chemically synthesized drugs used in drug therapy have unsatisfactory short-term curative effects on ALD, and there are potential hepatotoxicity problems in long-term use. Therefore, there is still a lack of ideal drugs for the treatment of ALD.

Abstract

The invention relates to the field of medicine and discloses a fat-reducing medicine, comprising extracts of notoginseng, ginkgo leaves, kudzu roots, red sage roots and red peony roots and polysaccharide-peptide. The weight ratio of the notoginseng to ginkgo leaves to kudzu roots to red sage roots to red peony root to polysaccharide-peptide is 1: (1 to 4): (0.5 to 2): (1 to 4): (0.5 to 2): (0.05 to 0.4). The raw material is extracted by a water extraction method or an alcohol extraction method, and is absorbed and purified through macroporous resin. The medicine is suitable to prepare medicines for curing hyperglycemia, fat liver or Alcoholic fatty liver.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine pharmacy, in particular to a traditional Chinese medicine composition with lipid-lowering effect, a preparation method and an application in the preparation of a medicine for treating fatty liver. Background technique [0002] With the improvement of people's living standards and changes in lifestyle, the importance of liver disease in the spectrum of human diseases has become increasingly prominent, and fatty liver disease (referred to as fatty liver) has become one of the common clinical chronic diseases. Some recent studies have shown that fatty liver can lead to insulin resistance, which can progress to liver fibrosis, cirrhosis, and even liver failure. Lipid metabolism disorder causes lipid accumulation, which in turn causes lipid peroxidation damage, which is the pathogenesis of fatty liver. [0003] Alcoholic liver disease (ALD) is caused by long-term heavy drinking, t...
