Incense resin is a sticky, viscous natural substance that is excreted by aromatic trees or plants as a protective response to injury or damage.

Incense resin is harvested, dried and burned as incense, releasing its pleasant aroma. It is often used in religious and spiritual ceremonies, as well as for its therapeutic properties in aromatherapy. Some common types of incense resin include frankincense, myrrh, copal, and benzoin.
