Arnica cordifolia of the Asteracea family is commonly known as heart leaf Arnica. It is a perennial plant with opposite, heart-shaped leaves that appear half way up the stem. It is topped with one or more a daisy-like bright yellow flower heads. Seeds are dispersed by the wind. The individual plant may live to 10-15 years, and it may even survive wild land fire.
Arnica cordifolia is native to Western North America. Arnica is found in both mountain meadows and forests of oak, Douglas fir, and pine.
Arnica is used topically as plant medicine in salves and liniments to treat bruises, strains and sprains. It is also a common homeopathic remedy. Eating arnica can be dangerous, as it can cause severe intestinal damage.
