Loess, a fine, silt-rich sediment, has been used in traditional Chinese medicine (TCM) for centuries, including topical applications for minor wounds such as scratches and abrasions. Historical TCM texts describe loess (commonly referred to as "Huangtu") as an agent for drying dampness and aiding wound healing, often applied as a powder or paste directly to the skin. The rationale is largely based on its absorptive properties and its perceived ability to promote tissue regeneration and reduce inflammation according to traditional theory. However, there is minimal scientific research specifically validating the efficacy of loess for treating scratches and abrasions. Modern studies on loess focus mostly on its mineral content and environmental impact rather than medical uses. No well-controlled clinical trials or peer-reviewed studies have established its safety or effectiveness for skin injuries. Therefore, while its use is justified by tradition and historical texts, the level of evidence supporting its use for scratches and abrasions is very weak, and modern clinical guidance does not endorse it. Additionally, concerns exist about contamination or infection risks from applying unsterilized earth materials to open wounds.
