Sumac, particularly from the genus Rhus, has a history of use in traditional medicine across various cultures, especially in the Middle East and parts of Asia. Traditionally, preparations of sumac have been used topically to address skin irritation, rashes, and itching, although the documentation is largely anecdotal or found in folk medicine sources rather than rigorous clinical literature. The astringent properties of sumac, attributed to its tannin content, are believed to help soothe itching and reduce inflammation when applied to the skin.

However, there is a lack of robust scientific evidence or well-controlled clinical studies specifically validating the efficacy of sumac for treating itching (pruritus). Most contemporary research on sumac focuses on its antioxidant, antimicrobial, and anti-inflammatory properties, with only indirect implications for skin health. The traditional use is noted in ethnobotanical surveys and herbal compendia, but these sources do not provide high-quality clinical proof. Therefore, while sumac is traditionally used for itching, and its anti-inflammatory properties may offer some theoretical benefit, the evidence supporting its use is weak and not scientifically substantiated.
