Coptis chinensis, commonly known as Chinese goldthread, is a traditional Chinese medicinal herb that has been used for centuries to treat various gastrointestinal disorders, including inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn’s disease. The primary active component in Coptis chinensis is berberine, an isoquinoline alkaloid with demonstrated anti-inflammatory, antimicrobial, and antioxidative properties.

Recent scientific studies—primarily in vitro and in animal models—have shown that berberine can modulate inflammatory pathways relevant to IBD. For example, berberine has been found to inhibit the expression of pro-inflammatory cytokines (such as TNF-α, IL-1β, and IL-6) and reduce oxidative stress in colonic tissues. Furthermore, it appears to modulate the gut microbiota composition, which is increasingly recognized as an important factor in IBD pathogenesis. Some small clinical studies and case reports suggest potential benefit in human subjects, though large-scale randomized controlled trials are lacking.

Overall, while there is strong traditional use and growing scientific validation for Coptis chinensis in IBD, the evidence base is still developing. Its efficacy and safety profiles are promising but not yet conclusively established for clinical use in humans. Thus, Coptis chinensis is supported by both traditional use and emerging scientific evidence, warranting a moderate evidence rating.
