Quick Summary

Balsam of Tolu is an aromatic resin that comes from the tolu tree, a tropical American tree (Myroxylon balsamum). This resin is used in perfumery and as an ingredient in cough syrups and lozenges. It is a brown, thick substance that solidifies over time. While sometimes confused with oleoresins, true balsams like Tolu are distinct. The tolu tree also yields balsam of Peru and a fragrant, durable wood used in furniture. Canada balsam and Mecca balsam are not considered true balsams.12
