The use of potato for treating cuts is primarily rooted in traditional and folk medicine rather than robust scientific evidence. In various cultures, slices of raw potato have been applied to minor wounds, cuts, or burns, with the belief that the potato’s natural moisture, starch content, and cooling properties help soothe the skin, reduce inflammation, and accelerate healing. This practice is often mentioned in home remedy traditions, especially in rural areas or in historical contexts where access to modern medical supplies was limited.

However, scientific studies specifically evaluating the efficacy of potato in wound healing or infection prevention are extremely limited. Some research has explored isolated compounds from potatoes, such as phenolics and antioxidants, which may have mild antimicrobial or anti-inflammatory properties, but these findings have not been directly translated into clinical recommendations for treating cuts. Most health authorities do not recommend potato as a wound treatment, emphasizing the use of properly cleaned and sterile dressings instead. Overall, while the tradition persists in some communities, the supporting evidence is weak, and there is little scientific validation for its effectiveness.
