Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Chinese Rhubarb (Rheum palmatum), known as "Da Huang" in Traditional Chinese Medicine (TCM), has a long history of use for supporting the health of the lower digestive tract, including the rectum. Its primary traditional application is as a purgative or laxative to relieve constipation and clear "heat" or toxins from the body. In TCM, it is often prescribed for conditions described as "heat accumulation" in the intestines, which can manifest as constipation, abdominal fullness, or even hemorrhoids and anal fissures—issues that directly involve the rectum.

Although several modern studies have explored the general effects of Chinese Rhubarb and its active constituents (such as anthraquinones like emodin and rhein) on gastrointestinal function, most research has focused on its laxative effect and potential anti-inflammatory properties in the intestines. There is some animal and preliminary human data suggesting that rhubarb extracts can modulate gut motility and may have protective effects against intestinal inflammation and injury. However, direct clinical evidence specifically supporting its use for rectal disorders (such as proctitis or rectal inflammation) is limited.

Overall, while the use of Chinese Rhubarb for supporting rectal health is primarily justified by historical and traditional use, there is a moderate level of indirect evidence from modern studies based on its effects on gut motility and inflammation. The traditional rating reflects that it is commonly used in TCM for conditions involving the rectum, but robust scientific validation for rectal-specific benefits remains limited.
