Mountain Arnica Arnica Cordifolia
This native Arnica is a close relative of Arnica montana, which furnishes the well-known tincture that is applied to bruises and sprains. It has been employed as a stimulant in low fevers, but does not appear to have any value when used internally. The Mountain Arnica occurs in fir, spruce and aspen forests at 7000-12000 ft. The heads are yellow-centered and yellow-rayed, and bloom all summer on plants 1-2 ft. high.
