The Copaiba trees of the Copaifera L. type (Leguminosae Caesalpinoideae) exude a resinous oil called Copaiba oil from its trunk. This species is found in the northern South America, mainly in both the Brazilian States Para and Amazonas. Since the 16th century, its use as an anti-inflammatory and healing agent was reported when the first settlers of the Americas divulged that female Indians rubbed it on navels of newborn babies and the wounds of warriors suffered after battles (Salvador, 1975). The knowledge of the medicinal characteristics of the copaiba oil derives from an Indian legend, telling the tale of wounded animals rubbing their wounds against the copaiba trees to heal their injuries.
