Word Origin and History for benzoin
n.

balsamic resin obtained from a tree (Styrax benzoin) of Indonesia, 1560s (earlier as bengewine, 1550s), from Middle French benjoin (16c.), which comes via Spanish, Portuguese, or Italian from Arabic luban jawi "incense of Java" (actually Sumatra, with which the Arabs confused it), with lu probably mistaken in Romance languages for a definite article. The English form with -z- is perhaps from influence of Italian benzoi (Venetian, 1461).
