Synopsis

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

Green tea (Camellia sinensis) has been traditionally consumed for its general health benefits in various cultures, particularly in East Asia. Its use for digestive complaints, including symptoms similar to those of Irritable Bowel Syndrome (IBS), can be traced back to traditional Chinese and Japanese medicine, where green tea is valued for its purported ability to "harmonize the stomach" and support digestion. However, scientific evidence specifically supporting green tea as a treatment for IBS remains limited and inconclusive. Most clinical research on green tea focuses on its antioxidant, anti-inflammatory, and antimicrobial properties, as well as its potential to modulate gut microbiota. These properties could theoretically benefit some IBS symptoms, such as abdominal discomfort or mild inflammation, but robust clinical trials directly demonstrating efficacy in IBS patients are lacking. Some studies suggest that polyphenols found in green tea may have a soothing effect on the gut and help reduce oxidative stress, but these findings are preliminary. In summary, while green tea has a long history of traditional use for digestive health, strong scientific evidence supporting its use specifically for IBS is not yet established, and its effect on IBS remains largely anecdotal or extrapolated from general digestive benefits.
