Frankincense, also known as olibanum, is an aromatic resin used in incense and perfumes, obtained from trees of the genus Boswellia in the family Burseraceae. The word is from Old French franc encens. There are several species of Boswellia that produce true frankincense: Boswellia sacra, B. frereana, B. serrata, and B. papyrifera. Resin from each is available in various grades, which depends on the time of harvesting. The resin is hand-sorted for quality.
