Canaigre (Rumex hymenosepalus), also known as wild rhubarb or Canaigre dock, has a longstanding history of traditional use among Native American groups in the southwestern United States. The root is rich in tannins, which are astringent compounds known to help contract tissues and reduce minor bleeding. Because of these properties, poultices or washes made from Canaigre root have historically been applied to minor wounds, abrasions, and skin irritations in folk medicine as a means of promoting healing and preventing infection. However, while these traditional practices are well-documented in ethnobotanical sources, there is a lack of robust scientific studies directly evaluating the efficacy of Canaigre tannates in treating abrasions. There are no controlled clinical trials or modern pharmacological studies specifically supporting its use for this purpose. The evidence for its use in abrasions, therefore, remains largely anecdotal and rooted in traditional herbal medicine rather than scientific validation. The rating of 1 reflects the presence of a traditional rationale but little to no modern research confirming effectiveness or safety for this application.
