Bai Ji (Rhizoma Bletillae, the tuber of Bletilla striata) has a long history of use in Traditional Chinese Medicine (TCM) for the treatment of abrasions, wounds, and bleeding. In classical TCM texts, Bai Ji is described as having properties that help "astringe" and "stop bleeding," making it a common ingredient in herbal poultices for minor skin injuries. The powdered form of Bai Ji is often applied topically to cuts, abrasions, and ulcers to promote hemostasis (the stopping of bleeding) and to accelerate healing by providing a protective layer over the wound. This traditional use is well-documented in TCM compendia and remains popular in various Asian countries.

While some modern pharmacological studies have investigated Bai Ji's effects, most available evidence remains preclinical, involving in vitro (test tube) or animal models. These studies suggest Bai Ji may promote wound healing by enhancing fibroblast proliferation, decreasing inflammatory cytokines, and forming a physical barrier that protects wounds. However, comprehensive clinical trials in humans are lacking, and the majority of its use for abrasions is justified by historical precedent rather than robust clinical validation. Thus, the use of Bai Ji for abrasions is primarily based on traditional knowledge, with a moderate level of traditional evidence and limited but promising early scientific exploration.
