Rating (out of 5): 2

Allium species, particularly garlic (Allium sativum) and onion (Allium cepa), have been used in traditional medicine for various oral ailments, including canker sores (aphthous ulcers). Folk remedies across cultures have suggested the topical application of crushed garlic or onion, or rinsing the mouth with their extracts, as a means to alleviate pain, reduce inflammation, and promote healing of mouth ulcers. The rationale in traditional use is based on the perceived antimicrobial and anti-inflammatory properties of Allium compounds such as allicin (in garlic) and quercetin (in onion). However, while there is some laboratory evidence that Allium extracts possess antibacterial and anti-inflammatory activities, there is a lack of direct clinical trials or robust scientific studies specifically evaluating the efficacy of Allium preparations for canker sores. Most references to their use for this condition are anecdotal or derived from herbal medicine compendia rather than scientific literature. Therefore, the evidence supporting Allium for canker sores is primarily traditional, with a low overall strength due to the absence of modern clinical validation.
