Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Rhus glabra (smooth sumac) has a history of traditional use among various Native American tribes for treating skin ailments such as rashes and hives. Ethnobotanical records indicate that the berries, leaves, and bark of Rhus glabra were used in poultices, washes, or decoctions to soothe inflamed skin and manage eruptions. The rationale for its use stems largely from observed anti-inflammatory and astringent properties attributed to tannins and polyphenolic compounds present in the plant parts. However, these historical uses are primarily anecdotal and passed down through oral tradition or documented in ethnobotanical surveys. There is a lack of clinical trials or robust pharmacological studies validating its efficacy or safety for these dermatological conditions in humans. Limited in vitro research has suggested some antimicrobial and anti-inflammatory potential in extracts of Rhus glabra, but these findings have not been directly linked to the treatment of rashes or hives specifically. Therefore, the justification for using Rhus glabra in this context is largely traditional, with modest supporting evidence from preliminary phytochemical studies but no strong scientific validation.
