Synopsis

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

Chinese Sumac (Rhus chinensis) has been used in traditional Chinese medicine (TCM) for centuries, primarily for its astringent, anti-diarrheal, and antimicrobial properties. Within the context of TCM, Chinese Sumac galls ("Wu Bei Zi") are sometimes included in formulations aimed at relieving gastrointestinal discomfort, including symptoms like gas and bloating. The historical rationale is rooted in the gall’s ability to "astringe the intestines," reduce dampness, and thereby alleviate certain digestive issues. However, most references relate to the treatment of diarrhea, dysentery, and excessive intestinal movement rather than specifically targeting gas and bloating.

There is limited modern scientific evidence supporting the specific use of Chinese Sumac for gas and bloating. Some laboratory studies have suggested antimicrobial and anti-inflammatory properties, which could theoretically contribute to gut health, but these do not directly address flatulence or bloating. The bulk of available support for its use in this context is therefore traditional, with little robust clinical validation. Thus, the evidence rating for its efficacy in treating gas and bloating is low, primarily due to the lack of targeted research and clinical studies.
