A Study on Sumac Mouth Rinse for Treating Recurrent Aphthous Stomatitis

Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal disorders, characterized by recurrent, painful ulcers that interfere with eating and speaking. The etiology of RAS is multifactorial and involves immune dysregulation and increased levels of inflammatory cytokines, particularly tumor necrosis factor-alpha (TNF-α). Sumac (Rhus coriaria) is a natural herbal extract known for its anti-inflammatory, antioxidant, and antimicrobial properties. This randomized controlled clinical study aims to evaluate the clinical effectiveness of a Sumac mouth rinse in promoting ulcer healing and reducing pain among patients with recurrent aphthous stomatitis. In addition to clinical assessment, biochemical evaluation of serum TNF-α levels will be performed before and after treatment to investigate the possible anti-inflammatory mechanism of Sumac. The study findings are expected to provide new insights into the potential therapeutic role of Sumac in managing RAS.
