What aromatic resin from Boswellia trees is commonly burned as incense? Frankincense is the aromatic resin produced by several Boswellia species.

Harvesters make shallow cuts in the bark, allowing the tree to exude resin that hardens into pale “tears.” The resin is collected, graded, and often burned over charcoal; its smoke has a warm, woody, balsamic fragrance. Olibanum is another name for frankincense.

Frankincense has been traded across Arabia and the Horn of Africa for more than 5,000 years. Ancient Egyptians used it in religious practices and mummification, while the Hebrew Bible describes it as a sacred incense ingredient. It is also one of the gifts presented by the Magi in the Gospel of Matthew.

A common mix-up is myrrh: both are fragrant resins from the Burseraceae family and may be burned together, but frankincense comes from Boswellia, whereas myrrh comes mainly from Commiphora. Major frankincense species include Boswellia sacra, B. papyrifera, B. frereana, and B. serrata.
