Arnica FAQs

Why is Arnica effective?

Sesquiterpene lactones (SQLs) are the active components of A. Montana flowers and are found in the base of the plant.  When applied topically (to the skin) at the concentration of 15%, the SQLs will penetrate the skin barrier effectively1.  SQLs target the inflammatory cascade thereby causing an anti-inflammatory effect2, 3, 4. It should be noted that though RUB·A535™ is most commonly known for its effective counterirritant products, RUB·A535™ Arnica is not a counterirritant. Arnica montana is considered a traditional herbal medicine.
