Rating (out of 5): 2

Polygonum (a genus that includes several species such as Polygonum cuspidatum, Polygonum aviculare, and Polygonum multiflorum) has been used in traditional medicine systems, particularly in Chinese and other East Asian practices, for managing hemorrhoids. The most commonly referenced species for this indication is Polygonum cuspidatum (Japanese knotweed). Traditional texts and herbal formularies describe the use of various Polygonum species to “cool blood,” “stop bleeding,” and reduce swelling, properties that are aligned with the symptoms of hemorrhoids (such as bleeding and inflammation). These uses are primarily based on long-standing empirical practices rather than robust clinical trials.

Scientific validation for the efficacy of Polygonum species in the treatment of hemorrhoids is limited. While some compounds found in Polygonum, like resveratrol and other polyphenols, are known for anti-inflammatory and antioxidant properties, there is a lack of high-quality clinical studies specifically evaluating its effectiveness for hemorrhoids in humans. Most available studies are preclinical, focusing on general anti-inflammatory effects or wound healing, rather than direct evidence for hemorrhoid management.

In summary, the use of Polygonum for hemorrhoids is primarily justified by tradition, with modest evidence from preclinical research supporting its biological plausibility. However, direct scientific validation in the context of hemorrhoids is lacking.
