Note: The balsams are aromatic resinous substances, flowing spontaneously or by incision from certain plants. A great variety of substances pass under this name, but the term is now usually restricted to resins which, in addition to a volatile oil, contain benzoic and cinnamic acid. Among the true balsams are the balm of Gilead, and the balsams of copaiba, Peru, and Tolu. There are also many pharmaceutical preparations and resinous substances, possessed of a balsamic smell, to which the name balsam has been given.
