Source of validity: Traditional
Rating (out of 5): 2

Arnica, particularly in the form of topical preparations (such as creams, ointments, or tinctures), has a long history of traditional use for treating external bleeding, bruises, and minor wounds. This use is rooted in European folk medicine, where Arnica montana has been applied to the skin to help stop bleeding from cuts and scrapes, reduce swelling, and promote healing. The plant contains compounds such as helenalin, which are believed to have anti-inflammatory and mild analgesic properties. However, scientific validation for Arnica’s effectiveness specifically in stopping external bleeding is limited. Most modern clinical research focuses on Arnica’s potential to reduce bruising and swelling rather than explicitly on hemostasis (the stopping of bleeding). A few laboratory studies suggest Arnica may have mild antibacterial and anti-inflammatory effects, which could support wound healing, but these do not confirm a direct effect on bleeding. Importantly, Arnica should never be applied to open wounds or broken skin due to the risk of irritation, allergic reactions, or toxicity. In summary, while the use of Arnica for external bleeding is primarily justified by traditional practices, scientific evidence supporting its efficacy and safety for this purpose remains weak and indirect.
