Effects of berberine gelatin on recurrent aphthous stomatitis: a randomized, placebo-controlled, double-blind trial in a Chinese cohort

Recurrent aphthous stomatitis (RAS) is a common oral mucosal disease, yet effective therapeutic approaches are lacking. This study aimed to determine the effects of application of berberine gelatin in the treatment of minor RAS (MiRAS).A randomized, double-blind, placebo-controlled, clinical trial was performed. The gelatin containing berberine (5 mg/g) or vehicle only was applied 4 times per day for 5 days. Clinical evaluation included pain level, size, erythema, and exudation of certain ulcers on days 1, 2, 4, and 6.A total of 84 subjects fulfilled the study without obvious side effects. Berberine gelatin treatment reduced the ulcer pain score compared with placebo gelatin (P0.05). Ulcer size was significantly reduced (P0.05) and lower erythema (P0.05) and exudation (P0.05) levels were associated with berberine treatment.Berberine gelatin may be a safe and effective treatment for MiRAS.
