Cowherb, also known as Vaccaria segetalis or Wang Bu Liu Xing in traditional Chinese medicine (TCM), has been used for centuries primarily for its effects on promoting blood circulation and reducing swelling. In traditional practice, it has occasionally been incorporated into topical remedies for minor skin injuries, including abrasions, with the belief that enhancing circulation and resolving stasis can facilitate wound healing and reduce inflammation. However, the use of Cowherb specifically for treating abrasions is not a predominant or well-documented function in classical TCM texts; its main indications are more focused on menstrual and lactation issues. When it is used for abrasions, it is typically as part of a larger herbal formula rather than as a single agent.

There is little direct scientific research validating Cowherb’s efficacy in treating abrasions. Most available studies and pharmacological investigations concern its anti-inflammatory, analgesic, and circulatory effects in vitro or in animal models, not specifically wound healing or skin repair. As such, the justification for its use in abrasions rests primarily on tradition and limited anecdotal evidence, rather than robust clinical trials or detailed mechanistic studies. Therefore, the evidence supporting Cowherb's use for abrasions is modest and largely historical in nature.
