The use of Manchurian Thorn (Crataegus pinnatifida), also known as Chinese Hawthorn, for scratches and abrasions is primarily rooted in traditional medicine rather than scientific validation. In Traditional Chinese Medicine (TCM), hawthorn is most commonly used for digestive and cardiovascular health, and it is not widely cited as a primary remedy for skin injuries like scratches or abrasions. However, some traditional sources mention hawthorn leaves and fruits as having mild astringent properties, which may have led to occasional use in poultices or topical preparations for minor wounds. The evidence for this use is minimal, and it is largely anecdotal or based on general traditional practices related to wound care, rather than specific to Manchurian Thorn itself.

Modern scientific literature does not provide direct studies or clinical evidence supporting the efficacy of Manchurian Thorn for treating scratches or abrasions. Most research on Crataegus pinnatifida focuses on its antioxidant, anti-inflammatory, and cardioprotective properties, with little to no attention to wound healing or skin repair. Therefore, while there is a minor traditional precedent for its topical use in wound care, this is not strongly established or validated by scientific research.
