Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Arnica (Arnica montana) has a long-standing history in traditional herbal medicine, particularly in Europe, for the topical treatment of bruises, muscle pain, and stiffness, including conditions like a stiff neck. Traditionally, arnica is applied as a cream, gel, or ointment directly to the affected area. The belief is that its anti-inflammatory and analgesic properties help reduce pain and improve mobility. The main active compounds, such as helenalin, are thought to inhibit inflammatory pathways, which could theoretically benefit musculoskeletal discomfort.
However, scientific studies specifically evaluating arnica for "stiff neck" are limited. Some clinical trials suggest that topical arnica preparations may offer mild benefit for muscle soreness and localized pain, but the overall quality of evidence is modest, and results are mixed. For example, small studies have found arnica gel to be at least as effective as low-concentration topical NSAIDs for some types of musculoskeletal pain, but robust, high-quality trials targeting neck stiffness are lacking.
In summary, arnica’s use for stiff neck is primarily justified by tradition, with moderate (2/5) evidence from small, lower-quality studies for general muscle pain and stiffness, but no substantial scientific consensus supporting its efficacy for neck stiffness specifically. It should not be ingested, as it can be toxic; topical use is generally considered safe for most people when applied to unbroken skin.
