What does benzoin mean?
Benzoin is a balsamic resin obtained from trees of the genus Styrax, native to Southeast Asia. When tapped, the trees exude a brittle, reddish-brown gum that gives off a warm, sweet, vanilla-like aroma, which has made benzoin a valued ingredient in incense, perfumery, and traditional remedies since antiquity. Traders brought it westward along ancient spice routes, where it was burned in religious ceremonies alongside frankincense and myrrh. In modern practice, benzoin appears most often in fine fragrances as a fixative and base note, in compounded tinctures applied topically to protect skin, and in some flavourings. Chemists also know benzoin as the name of a distinct crystalline compound formed by joining two molecules of benzaldehyde — a substance that gave rise to the broader family of 'benzene' terms. The word thus bridges two worlds: an ancient sacred gum and a cornerstone of organic chemistry.
A balsamic resin obtained from trees of the genus Styrax, used in incense, perfumery, and traditional medicine.
"She warmed a small piece of benzoin over charcoal, releasing its honeyed, vanilla-like fragrance."
This is by far the dominant sense in general usage.
(Chemistry) A crystalline compound, 2-hydroxy-1,2-diphenylethanone, produced by the condensation of benzaldehyde and used in organic synthesis.
"The reaction converted benzaldehyde into benzoin under cyanide catalysis."
Restricted to technical chemistry contexts.
Rarely pluralised; when plural, typically refers to different grades or varieties of the resin (e.g. Siam and Sumatra benzoins) rather than discrete countable pieces.
"Perfumers distinguish between several benzoins, each with its own characteristic sweetness."
Benzoin's name traces back through French and Italian to the Arabic for 'Javan frankincense' — a resin so prized it helped name the entire family of benzene chemicals.

Etymology of benzoin
The word 'benzoin' entered English in the late sixteenth century, borrowed from French benjoin (with an intrusive -z- influenced by Arabic-derived spellings), ultimately tracing back through medieval Latin and Italian to the Arabic phrase lubān jāwī, meaning 'frankincense from Java'. Over time the initial element was reinterpreted, giving forms such as 'benjamin' as a variant name for the same resin. From this same source came the adjective 'benzoic', coined when chemists isolated benzoic acid from the resin, and subsequently 'benzene', 'benzyl', and other members of the benzene chemical family.
How benzoin is actually used
In everyday use 'benzoin' almost always refers to the aromatic resin, especially in perfumery, incense, and herbal medicine contexts. The chemical sense is confined to technical chemistry writing. In commerce, the resin is graded by origin — notably Siam benzoin (from Thailand) and Sumatra benzoin — each with distinct scent profiles.
Easily confused with benzoin
Benzene is a liquid hydrocarbon (C6H6) used as an industrial solvent and chemical feedstock, whereas benzoin is either a fragrant tree resin or a specific organic compound formed from two benzaldehyde molecules.
