Arnica (Arnica montana) has a long history of use in traditional herbal medicine, particularly in Europe, for treating various skin conditions, including external ulcerations, bruises, and wounds. Its use for ulcerations is primarily rooted in folk and traditional practices, often as poultices, ointments, or tinctures applied to the affected area. Traditional herbalists believed arnica could promote healing, reduce inflammation, and decrease pain. However, the direct application to broken skin, such as ulcerations, has been controversial even in traditional use due to the potential for irritation or sensitization.

From a scientific perspective, there is very limited evidence supporting the use of arnica on external ulcerations. Most modern research on arnica focuses on its anti-inflammatory and analgesic effects, particularly for bruises and muscle pain, rather than open wounds or ulcerations. Some laboratory studies suggest arnica contains compounds (like sesquiterpene lactones) that have anti-inflammatory and antimicrobial properties, but robust clinical studies on its safety and efficacy for treating ulcerations specifically are lacking. Furthermore, arnica is generally contraindicated for use on broken skin in medical and herbal references due to the risk of allergic reactions and toxicity.

In summary, while arnica’s use for external ulcerations is grounded in tradition, there is little scientific evidence to support its safety or efficacy for this indication, and caution is advised due to potential adverse effects.
