Synopsis

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

Rhus coriaria, commonly known as sumac, has a long history of traditional use, particularly in Middle Eastern and Mediterranean cultures, for oral and gum health. Traditional medicine systems have employed sumac berries and extracts for their purported astringent, antimicrobial, and anti-inflammatory properties. Historical records and ethnobotanical surveys indicate that sumac preparations, such as decoctions or powders, have been used as mouthwashes or applied directly to the gums to help with conditions like gingivitis, mouth ulcers, and general oral hygiene.

The rationale for these traditional uses likely stems from the high content of tannins and polyphenols in Rhus coriaria, which are known for their astringent qualities and potential to tighten tissues and reduce minor bleeding. Additionally, the antimicrobial activity of sumac against certain oral pathogens has been suggested in folk medicine, supporting its reputation as an oral health remedy.

However, while some recent in vitro studies have demonstrated antibacterial effects of Rhus coriaria extracts against bacteria that can cause gum disease, rigorous clinical trials in humans are lacking. Therefore, the evidence remains primarily traditional, with some preliminary scientific support that has not yet reached a level sufficient to shift the justification from traditional to scientific.
