Rating (out of 5): 2

Rhus coraria, commonly known as sumac, has a long history of traditional use in various cultures for treating minor skin injuries such as scratches and abrasions. Historical texts and ethnobotanical surveys document the topical application of sumac leaves or fruit preparations to support wound healing and reduce the risk of infection. The rationale behind its use stems from its astringent properties, attributed to a high content of tannins and other polyphenolic compounds, which can help contract tissues and form a protective layer over wounds.

While in vitro studies have demonstrated that extracts of Rhus coraria possess antimicrobial and antioxidant activities, direct scientific evidence specifically evaluating its efficacy on scratches and abrasions in human clinical settings is lacking. Most of the support comes from traditional medical systems, particularly in the Middle East and Mediterranean regions, where sumac poultices or washes have been applied to minor wounds for centuries. In summary, the use of Rhus coraria for scratches and abrasions is primarily justified by tradition, and while its phytochemical profile suggests a plausible benefit, robust clinical validation is currently insufficient.
