Vietnamese benzoin essential oil has a sweet inviting aroma setting the scene of a pleasant summer’s day. As it exudes, the resin is yellowish. But when it thickens and hardens, it becomes brownish-red. It has a strong smell of vanilla, and is very aromatic; to taste, it is rather acrid. The resin is cleaned, and is available powdered, in two forms of a tincture, simple and compound (the latter benzoin tincture being too strong for use on the skin), or as an essential oil.
