Description: The trunk of the frankincense tree exudes a sticky substance called resin. This resin is made up of roughly 65% gum, 30% resin and 4% essential oil. It can be harvested once the resin has hardened into crystals. Historically, Frankincense has been used in perfumes & cosmetics for thousands of years. Today it remains a fragrance component in soaps, incense, and of course, cosmetics and perfumes.
