A systematic review of 53 references across 18 ethnic groups in Thailand has cataloged 181 species of medicinal plants traditionally used to treat hemorrhoids. The plants belong to 147 genera and 78 families, with the most frequently cited species including Cissus quadrangularis, Biancaea sappan, and Mimosa pudica.
Researchers found that these plants are reported to have anti-inflammatory, anti-oxidative, anti-microbial, anti-hemorrhoid, analgesic, and vasorelaxant activities. However, the review did not test these plants in patients or compare them to standard treatments.
This is a catalog of traditional knowledge, not a clinical trial. The review did not report on safety, side effects, or how well these plants work compared to conventional hemorrhoid treatments. The findings are meant to guide future research, not immediate use.
Readers should not try these plants without consulting a doctor. Many medicinal plants can have side effects or interact with medications. This research is a starting point for developing new treatments, not a recommendation for self-treatment.
