The main countries producing frankincense (olibanum), the resin of trees of the genus Boswellia
There are many varieties of trees that produce frankincense resin. These are always trees of the Boswellia genus, of the Burseraceae family.
The continent that produces and exports the most is Africa, led by Somalia. But it is also found in Ethiopia, Kenya, Eritrea, Sudan, Nigeria and Burkina Faso. The rest comes from the Sultanate of Oman, Yemen, the island of Socotra, or India.
The resin is widely used in the pharmaceutical and perfume industries. A small part is used as incense for burning, mainly in churches (Catholic, Orthodox...) or by individuals, to enjoy its fragrance or for ceremonies of purification, protection, etc.
