Modern research shows that active ingredients such as berberine in coptis also have antibacterial, anti-inflammatory, and hypoglycemic effects. This article will start from four aspects: traditional application, pharmacological mechanism, clinical research and precautions, and analyze the value and limitations of Coptis chinensis in a clear and primary way.

The application of Coptis chinensis in traditional Chinese medicine

In the "Compendium of Materia Medica", Coptis chinensis is listed as a top-grade medicinal material. It is cold in nature and bitter in taste.

Patients with damp-heat syndrome can use it under the guidance of a doctor to avoid abuse on their own. Future research can further explore new directions such as anti-tumor and regulating intestinal flora, but the existing evidence does not support its replacement of conventional treatment.
