Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Lemon has been traditionally used in various cultures as a home remedy for canker sores (aphthous ulcers) due to its acidic nature, antimicrobial properties, and high vitamin C content. Folk remedies often suggest applying lemon juice directly to the sore or rinsing the mouth with diluted lemon water, with the belief that it can help disinfect the ulcer, speed up healing, or provide vitamin C to support oral health. However, the direct application of lemon juice is frequently reported to cause significant stinging and discomfort, and there is little scientific evidence supporting its efficacy for this purpose. In fact, the acidity of lemon may irritate the mucous membranes further and potentially delay healing rather than promote it. While vitamin C is important for mucosal and immune health, most scientific studies recommend its oral supplementation rather than topical application of acidic substances for canker sores. Overall, while lemon's use is rooted in tradition, current scientific evidence does not support its safety or effectiveness for treating or supporting canker sores. In some cases, it may even be counterproductive.
