A clinical trial was carried out to look at the effectiveness of a gel made from fresh, organic Arnica montana flower heads against one of the leading pharmaceutical gels, Ibuprofen, with very positive results. Twenty doctors in Switzerland undertook a strictly controlled study involving 204 patients using A.Vogel Arnica Gel and Ibuprofen gel. Improvement in the two main areas had to be achieved for the study to be successful and in both cases Arnica Gel proved to be as effective as the pharmaceutical pain-killer.
