Cynanchum species, particularly Cynanchum atratum and Cynanchum paniculatum, have been used in traditional Chinese medicine (TCM) for various ailments, including skin issues such as abrasions, sores, and ulcers. Historical TCM texts describe preparations of Cynanchum roots being applied topically to promote healing and reduce inflammation. The justification for its use is rooted in its traditional reputation for "clearing heat" and "detoxifying" the skin, which is believed in TCM theory to facilitate the recovery of damaged skin tissue.

However, there is limited modern scientific research directly validating the efficacy of Cynanchum for treating abrasions. Some laboratory studies have explored the anti-inflammatory and antimicrobial properties of extracts from Cynanchum species, which could theoretically contribute to wound healing. For example, in vitro studies have shown that certain compounds from Cynanchum exhibit inhibition of bacterial growth and reduction of inflammatory markers. However, these findings are preliminary and do not specifically address clinical outcomes in abrasion healing.

In summary, the primary basis for using Cynanchum in abrasion treatment is traditional practice rather than strong scientific evidence. More rigorous clinical trials are needed to determine its true efficacy and safety for this purpose.
