Frankincense is a resin obtained from trees of the genus Boswellia, which are native to the Arabian Peninsula and northeastern Africa. The resin is harvested by making incisions in the bark of the tree and allowing the sap to flow out and harden into small, tear-shaped droplets.

Frankincense has been used for centuries in various cultures for its medicinal and spiritual properties. It is commonly burned as incense and used in perfumes, cosmetics, and traditional medicine. It has been shown to have anti-inflammatory and anti-cancer properties, and may also have benefits for skin health and digestion.
