Bloodroot (Sanguinaria canadensis) has a long history of use in traditional Native American medicine, especially for external applications such as wound care and to stop bleeding. Historical ethnobotanical records document that several Native American tribes used poultices or salves containing bloodroot to treat wounds, ulcers, and other skin conditions, with the belief that it could staunch bleeding and promote healing. The plant’s latex, which contains the alkaloid sanguinarine, was applied topically and sometimes combined with other botanicals. However, this use is primarily rooted in tradition and anecdotal reports rather than scientific evidence.

Modern scientific evaluation of bloodroot’s hemostatic (bleeding-stopping) properties is lacking. While sanguinarine does possess antimicrobial and cytotoxic activities, there are no rigorous clinical studies or pharmacological validations supporting the efficacy or safety of bloodroot for stopping external bleeding. Furthermore, bloodroot can be an irritant and cause tissue damage, raising concerns about its topical use on open wounds. Thus, while its application for external bleeding is supported by traditional use, the quality and quantity of evidence are low, and contemporary medical sources do not recommend it for this purpose.
