Blackthorn (Prunus spinosa) has a long-standing history in European folk medicine, where various parts of the plant—such as its bark, flowers, and fruit—have been used for different medicinal purposes. In the context of skin abrasions and minor wounds, traditional use is documented primarily in ethnobotanical surveys and herbal compendiums. Blackthorn preparations, particularly topical applications of decoctions or infusions made from the bark or flowers, have been employed as mild astringents to help cleanse wounds, reduce minor bleeding, and promote healing. These practices are rooted in the plant's astringent and mildly antimicrobial properties, as recognized in traditional herbal medicine.

However, there is very limited modern scientific research specifically validating the efficacy of Blackthorn for treating abrasions. While laboratory studies have indicated some antimicrobial and anti-inflammatory activities in extracts of Prunus spinosa, these findings are preliminary and not directly linked to clinical outcomes for wound healing in humans. No robust clinical trials or systematic reviews have been published on this specific use. As such, while Blackthorn’s application for abrasions is supported by tradition, current scientific evidence is scant, resulting in a low evidence rating.
