Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) has been traditionally consumed for its general health benefits, but in recent years, scientific interest has grown surrounding its potential role in managing colitis, particularly ulcerative colitis and Crohn’s disease. The active compounds in green tea, especially epigallocatechin-3-gallate (EGCG), have demonstrated anti-inflammatory and antioxidant properties in various in vitro and animal studies. These studies suggest that green tea polyphenols can reduce levels of pro-inflammatory cytokines (such as TNF-α and IL-6) and may help preserve the integrity of the intestinal mucosal barrier, both of which are relevant in the pathogenesis of colitis.

However, human clinical evidence remains limited and somewhat inconclusive. A few small clinical trials and pilot studies have indicated that green tea extract or EGCG supplementation may reduce disease activity or improve quality of life in people with inflammatory bowel diseases. For example, a 2013 pilot study showed modest improvement in disease activity scores among ulcerative colitis patients taking green tea extract, but larger, well-designed trials are still lacking. Therefore, while laboratory evidence is promising and provides a mechanistic rationale for its use, the clinical evidence supporting green tea as a treatment for colitis is currently weak, with a rating of 2 out of 5. Green tea may be used as a complementary approach but should not replace conventional therapies.
