Arnica comes from the perennial Arnica Montana which belongs to the Compositae family of daisy flowers. Other than Arnica, there are several other flowers used homeopathically and herbally within this family of plants, such as Echinacea, Calendula, Yarrow, Chamomilla, Solidago and Dandelion. This yellow-orangish flower grows on the mountains of Europe and Siberia, and is often referred to as the 'mountain daisy'.
Arnica has been used medicinally for centuries in Creams and Ointments for strains, sprains swelling and inflammation. Publicised trials that took place over in the United States of America also indicated that when used as topical application, Arnica encouraged healing after surgery and improved the pain in those with osteoarthritis. It was thought that the rich source of Manganese found in Arnica was responsible for facilitating the healing process.
