Arnica montana is a perennial herb grown in Southern and Eastern Europe and Siberia. Arnica montana has been known since the 16th century as a topical treatment for acute conditions such as sprains, bruises and painful swelling1.  Health Canada recognizes the therapeutic properties of Arnica montana2. RUB·A535TM uses Arnica montana that is grown sustainably in Spain and Romania.

The RUB·A535TM Natural Source Arnica Cream has a 25% concentration of Arnica montana flower, which is a herbal preparation. This is not a homeopathic remedy.
