Some authors suggest that the roots have therapeutic properties, but according to Farmacopéia Brasileira III (the official Brazilian pharmaceutical code), the floral capitula are the only parts used for medicinal and aromatic purposes.1 The origin of the name arnica is somewhat obscure. It might be a deformation of the Greek word ptarmikos, meaning something that causes a sneeze.Unknown in ancient times, the plant was first cited by Saint Hildegard. It was described and drawn by the Italian botany doctor Mattioli.2 This herbaceous plant reaches from 20 to 60 cm in height and releases a pleasant scent from its flowers which appear as separate capitula and are yellow or orange in color, as well as joyful and attractive. Arnica is a vivacious perennial plant and originates from European woods. It is abundant in the mountainous areas of Southern Europe (Alps, Pyrenees and the Vosges). In Brazil it is perfectly acclimatized to a number of different regions, mainly in the mountainous regions of Minas Gerais and the southern region of the country.1
