The plant has a long history in healing, dating back to the 1500s and to Native American healers. It is used for sprains and bruises and in treating the pain of arthritis, according to the University of Maryland Medical Center.

Arnica is a perennial plant. It is a member of the Asteraceae family, the same family as sunflowers. Arnica also displays yellow flowers in the spring that have a slight smell. It is cultivated for medicinal use. The dried flowers are the part utilized in medicine. Tinctures of the plant's flowers are made into homeopathic Arnica 30C.

The process is repeated 30 times, until the 30C dilution is reached.
