Frankincense resins are secreted from the bark of boswellia (frankincense) trees as a protective mechanism against insects and the environment in general. Resins are comprised mainly of terpenes, which are prized for their wide range of benefits.

Frankincense resins are distilled to make frankincense essential oils and hydrosols.

Resins can be burned or crushed up, and infused in olive oil or another carrier oil. Some people even like to chew on them, but that's a bit intense for most of us.
