Gum benzoin

Benzoin /ˈbɛnzoʊ.ᵻn/ or benjamin is a balsamic resin obtained from the bark of several species of trees in the genus Styrax. It is used in perfumes, some kinds of incense, as a flavoring, and medicine (see tincture of benzoin). It is distinct from the chemical compound benzoin, which is ultimately derived from benzoin resin; the resin, however, does not contain this compound.

Benzoin is also known gum benzoin or gum benjamin, but "gum" is misleading as benzoin is not a polysaccharide. Its name came via the Italian from the Arabic lubān jāwī (لبان جاوي, "frankincense from Java"). Benzoin is also called storax, not to be confused with the balsam of the same name obtained from the Hamamelidaceae family.

Benzoin is a common ingredient in incense-making and perfumery because of its sweet vanilla-like aroma and fixative properties. Gum benzoin is a major component of the type of church incense used in Russia and some other Orthodox Christian societies, as well as Western Catholic Churches. Most benzoin is used in Arab States of the Persian Gulf and India, where it is burned on charcoal as an incense. It is also used in the production of Bakhoor (Arabic بخور - scented wood chips) as well as various mixed resin incense in the Arab countries and the Horn of Africa. Benzoin is also used in blended types of Japanese incense, Indian incense, Chinese incense (known as Anxi xiang; 安息香), and Papier d'Arménie as well as incense sticks.
