Quick Summary

Balsam is an aromatic resin that comes from plants. It's composed of resin mixed with benzoic or cinnamic acid esters and is often used in medicinal preparations and incense. While sometimes confused with oleoresins (resins dissolved in essential oils), balsams are typically more solid.1

Balsam of Peru, a dark, fragrant fluid, is a true balsam derived from the Myroxylon pereirae tree, native to El Salvador. Although listed in pharmacopoeias, it lacks medicinal value but is used in perfumery. Balsam of Tolu, from Colombia, is also used in perfumery and cough remedies. Canada balsam and Mecca balsam are not considered true balsams.1
