This product is made from Frankincense harvested from trees in Oman. Frankincense is tapped from the very scraggy but hardy Boswellia tree by slashing the bark, which is called striping, and allowing the exuded resins to bleed out and harden. These hardened resins are called tears. There are numerous species and varieties of frankincense trees, each producing a slightly different type of resin. Differences in soil and climate create even more diversity of the resin, even within the same species.
Frankincense trees are also considered unusual for their ability to grow in environments so unforgiving that they sometimes grow directly out of solid rock. The means of initial attachment to the stone is not known but is accomplished by a bulbous disk-like swelling of the trunk. This disk-like growth at the base of the tree prevents it from being torn away from the rock during the violent storms that frequent the region they grow in. This feature is slight or absent in trees grown in rocky soil or gravel. The tears from these hardy survivors are considered superior for their more fragrant aroma.
The trees start producing resin when they are about 8 to 10 years old. Tapping is done 2 to 3 times a year with the final taps producing the best tears due to their higher aromatic terpene, sesquiterpene and diterpene content.
