Curcumin, the primary active component of turmeric (Curcuma longa), has been increasingly studied for its potential role in supporting or treating canker sores (aphthous ulcers). The evidence supporting its use is primarily scientific, with several small-scale clinical trials and in vitro studies indicating beneficial effects. Curcumin exhibits potent anti-inflammatory, antioxidant, and antimicrobial properties, all of which are relevant to the pathophysiology of canker sores, which involve local inflammation and tissue damage.

A number of randomized controlled trials (RCTs), mostly conducted in India and Iran, have evaluated curcumin gel or mouthwash in the management of minor aphthous ulcers. These studies generally report that topical curcumin can significantly reduce pain, erythema, and ulcer size compared to placebo, and in some cases, its efficacy is comparable to standard treatments like corticosteroid gels. For example, a 2014 double-blind study published in the Journal of Oral Pathology & Medicine found that a 2% curcumin gel was as effective as triamcinolone acetonide in decreasing ulcer severity and pain over 7 days.

It should be noted, however, that while these results are promising, most studies are small, and larger, well-designed clinical trials are needed to confirm efficacy and safety. Nonetheless, current scientific evidence supports the potential use of topical curcumin as an adjunct or alternative treatment for canker sores, particularly for individuals seeking non-steroidal options.
