Arnica (Arnica montana) has a long history in traditional European herbal medicine for use in treating external bleeding, bruises, and minor trauma. Traditionally, arnica flowers are prepared as tinctures, ointments, or compresses and applied topically to the skin over affected areas. The rationale for this use is based on anecdotal evidence and centuries of folk practice, where arnica was believed to reduce bleeding, swelling, and pain. Historical herbal texts from Europe, particularly Germany and Switzerland, document arnica’s application to wounds, cuts, and contusions.

However, while arnica is widely used in this way by herbalists, there is little robust modern clinical evidence to confirm its effectiveness specifically for stopping external bleeding. Most contemporary research on arnica has focused on its anti-inflammatory and analgesic properties, especially for bruising and muscle soreness, rather than hemostasis (stopping bleeding). Laboratory studies have identified compounds such as sesquiterpene lactones, which may have anti-inflammatory effects, but these do not directly address hemostasis.

It is important to note that arnica should not be applied to open wounds or broken skin due to risks of irritation, allergic reactions, and toxicity. Most traditional use involved application near, but not directly on, bleeding wounds. In summary, the use of arnica for external bleeding is primarily justified by traditional evidence, with limited scientific support and important safety considerations.
