Tolu Balsam

Tolu Balsam is a thick yellow or brown liquid obtained from myroxylon toluiferum, and other trees. It dries to a hard, yellow transparent solid, which, like the liquid balsam, possesses a fragrant, agreeable odour. It contains benzoic and cinnamic acids, together with derivatives of these compounds and resinous substances. It is used slightly in medicine as a stimulant and pectoral.
