Benzoin Gum Profile
Also known as- Styrax benzoin, barley gum, styrax gum
Introduction
If you can remember visiting the family doctor 40 or more years ago, you may remember the ubiquitous jar of "tincture of benzoin" kept on an office shelf for treating upper respiratory infections. The benzoin tree is native to the tropical reaches of eastern Asia. The resin, also called gum benjamin, ranges in color from pale yellow to red brown and is harvested by making triangular incisions into the tree's bark to establish a flow, which then hardens into lumps. Benzoin is used in the perfume industry as an antioxidant, stabilizer, and fixative. Will sometimes harden under fluctuations in humidity.
