Bois d'Encens

The Full Story
Did You Know?
Boswellia sacra trees can survive for over 200 years in the arid wadis of Dhofar, Oman. The trees require monsoon fog (the khareef) to survive — they grow in one of the few places on the Arabian Peninsula that receives regular moisture from the Indian Ocean monsoon.

In Perfumery
Base-note wood providing sacred-woody character without heavy incense sweetness. Functions in modern woody, minimalist, and subtle Amber compositions. Complements cedar, sandalwood, vetiver, and iris. Drier and more restrained than frankincense resin — useful when the idea of incense is wanted without its full olfactory weight.
