Ph. Eur. 6.2

(Sumatra Benzoin). A resin obtained by incising the trunk of Styrax benzoin. It contains 25 to 50% of total acids, calculated as benzoic acid (dried drug). Creamy white, rounded to ovoid tears, which may be embedded in a dull, greyish-brown or reddish-brown matrix. It is hard and brittle and the fractured surface is dull and uneven.

USP 31

(Benzoin). A balsamic resin from Styrax paralleloneurus or S. benzoin (Styracaceae). It yields not less than 75% of alcohol-soluble extractive. It occurs as blocks or lumps of variable size made up of tears, compacted together, with a reddish-brown, reddish-grey, or greyish-brown resinous mass. The tears are externally yellowish or rusty brown, milky white on fresh fracture, hard and brittle at ordinary temperatures but softened by heat. It has an aromatic and balsamic odour. When heated it does not emit a pinaceous odour. When digested with boiling water, the odour suggests cinnamates or storax.
