Traditional uses

Long before arnica oil sat on pharmacy shelves, mountain communities across Europe and Siberia were reaching for its cheerful orange blooms after a hard fall or a long day of labor, rubbing infused oils and salves into aching, bruised places. Arnica chamissonis, the leafy meadow cousin of the better known Arnica montana, grows wild in the wet high meadows of the American West and across Siberia, and it shares the same warming, traditional reputation for calming bruises and tired muscles when used on unbroken skin. Because true Arnica montana has grown scarce in parts of its native range, growers now cultivate Chamisso arnica as a hardier, more sustainable stand-in for the same time-honored remedies. It remains, above all, a plant of the outdoors, at home in cool alpine air and honest physical work.

Did you know?

The species is named for Adelbert von Chamisso, a German-French botanist and poet who collected it while circling the globe aboard the Russian ship Rurik between 1815 and 1818, the same voyage on which he helped describe how salps alternate between solitary and chain-forming generations.

Safety

Arnica is toxic if swallowed, causing nausea, vomiting, and irregular heartbeat, so it is for external use only and never on broken or irritated skin. It can trigger allergic reactions in people sensitive to ragweed or related daisy-family plants, and those on blood thinners should use caution.
