About this species

Boswellia sacra is a tree with papery, peeling bark and leaves clustered at the ends of tangled branches. It is the source of the oleo-gum-resin frankincense, which besides other uses, has long been valued for its sweet-smelling fumes when burnt. The name ‘frankincense’ is derived from the Old French ‘franc encens’, meaning pure incense or, more literally, free lighting. Trade in frankincense, which is produced by various trees in the genus Boswellia, dates back to at least 2000 BC. Up until the 1830s, many Europeans mistakenly believed that frankincense was the resin of a species of Juniperus, a conifer.
