Background: Recurrent aphthous ulceration is one of the most common inflammatory, ulcerative oral mucosal conditions. Most of the currently available treatments aim at symptomatic relief, thereby improving the quality of life. Aims and Objectives: To evaluate the efficacy of allicin in mouthrinse and systemic form in the management of minor recurrent aphthous stomatitis (RAS). Materials and Methods: A total of 42 patients with minor RAS were randomly divided into Group A (allicin mouth rinse-21) and Group B (allicin capsules-21). The baseline parameters of the ulcer, i.e., size, pain, and erythema were recorded on the day 1, day 4, and day 7, respectively. The recurrence rate of the ulcer was evaluated for 6 months at monthly intervals. Results: In both groups, the marked improvement was observed in the parameters during the follow-up visits. Both forms of allicin were proved to be effective but no statistically significant difference was observed. Recurrence was observed in both the groups. Conclusion: Both forms of allicin were found to be equally effective in the management of minor RAS with a good safety record. Both were not found to be effective in preventing the recurrence.
