Synopsis

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

Arnica (Arnica montana) has a long history of traditional use for the treatment of sprains, bruises, and other minor injuries. The use of arnica in this context dates back centuries in European herbal medicine, where it was commonly applied topically as a cream, ointment, or tincture to reduce swelling, pain, and discoloration from trauma. The traditional belief is that arnica possesses anti-inflammatory and analgesic properties that help to expedite the healing of soft tissue injuries like sprains.

While there is a strong tradition supporting arnica's topical use for sprains, scientific evidence remains limited and mixed. A few small randomized controlled trials and meta-analyses have examined topical arnica preparations for musculoskeletal pain, bruises, or sprains, with some reporting mild benefits compared to placebo, especially for subjective symptoms like pain and swelling. However, other studies have found no significant benefit over placebo, and the methodological quality of many studies is often low, with small sample sizes and inconsistent preparations. Systematic reviews generally conclude that while arnica appears safe for topical use, evidence for its efficacy in treating sprains is inconclusive and not robust enough to warrant strong recommendations.

In summary, arnica's use for sprains is supported primarily by tradition, with scientific research providing only limited and inconsistent validation. Topical application is generally considered safe, but oral forms are potentially toxic and not recommended. More high-quality clinical trials are needed to clarify its effectiveness.
