Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Alum, a compound commonly composed of potassium aluminum sulfate, has a long history of traditional use for treating minor wounds and oral lesions. Its primary traditional applications include functioning as an astringent and styptic, helping to stop minor bleeding and promote the drying of tissue. In various cultures, alum has been applied topically to mouth ulcers, canker sores, and minor cuts. The rationale behind its use is its ability to precipitate proteins on the surface of tissues, thereby creating a physical barrier that can reduce irritation and promote healing. However, scientific evidence supporting alum's efficacy for lesion treatment is limited. Most of the available literature consists of small-scale studies or anecdotal reports. Some in vitro and animal studies have indicated that alum may have mild antimicrobial and astringent effects, but robust clinical trials in humans are lacking. A few studies have evaluated alum's potential for reducing the duration of oral ulcers, with mixed results and generally low methodological quality. Overall, alum's use for lesion treatment is primarily justified by tradition rather than contemporary scientific validation. While it may provide symptomatic relief in some cases due to its astringent properties, its benefits and safety profile have not been conclusively established by rigorous clinical research. Caution is advised, particularly with prolonged or excessive use, as alum can cause local irritation or toxicity if misused.
