 "Tincture of benzoin has two main medical uses: as a treatment for damaged skin in the "Compound" form, and as an inhalant in the non-Compound form." [[https://en.wikipedia.org/wiki/Tincture_of_benzoin]]
-Main components of benzoin resin are coniferyl benzoate (60-80%), p-coumaryl benzoate (10-15%), cinnamyl benzoate, and benzoic acid. Vanilin (0.3%) as minor component has a great impact on the scent of benzoin. \\

+Benzoin balsam is a a pathological product resulting from tapping Styrax trees, it does not exude naturally from the trunk. Ethanolic extracts of the balsam contain volatile (30-40%) and nonvolatile (60-70%) compounds. Major non-volatile components are coniferyl benzoate (Siam benzoin: 29-56% of the crude material), cinnamyl cinnamate, and p-coumaryl cinnamate, minor ones p-coumaryl benzoate, coniferyl derivatives, morinol derivatives, cinnamyl benzoate, coniferyl cinnamate, siaresinolic acid, sumaresinolic acid, and 3-ox-siaresinolic acid. Important volatile components of the ethanolic extract are vanillin, benzoic acid (Siam benzoin: 31-36% of the crude material), cinnamic acid (Sumatra benzoin: 16-26% of the crude material), and benzyl cinnamate. \\
