Myroxylon balsamum (L.) Harms var. balsamum - syn.Toluifera balsamum L. - Fabaceae \\
Tolu balsam, opobalsam, **Tolubalsambaum**

Evergreen tree, native to northern South America (Venezuela to Peru); resin bled from the trunk solidifies to tolu balsam (balsam of Tolu, Balsamum tolutanum).

"The balsam has a sweet, pleasant and lasting aroma and is also considered to exhibit a certain fixative effect. It is commonly used as ingredient in confectionary products and cosmetics and as an additive to tobacco... The hexane-soluble fraction of an ethanolic solution of commercial tolu balsam, accounting for the most of the aroma, is shown to be a complex mixture, composed of aromatic and terpenoid compounds. Benzoic and cinnamic acid, the corresponding alcohols, aldehydes, ethyl, benzyl, and cinnamyl esters, methyl cinnamate, styren, eugenol, vanillin, benzyl ferulate and isoferulate, ferulic acid, and 1,2-diphenylethane are the aromatic compounds identified." \\

"The odour is sweetly balsamic, faintly floral and spicy, with an undertone of vanillin. It is similar to benzoin, but the odour comparision is less vanilla like and more cinnamic than benzoic in character."
Main components of the volatile fraction of Tolu resin were benzyl alcohol (43.4%), ethyl cinnamate (1.0%), cinnamic acid (1.4%), benzyl benzoate (50.7%), and cinnamyl cinnamate (1.5%). Minor components were e.g. benzaldehyde, methyl benzoate, ethyl benzoate, benzoic acid, cinnamic alcohol, methyl cinnamate, vanillin (0.02%), cinnamic acid (2.7%), cinnamyl benzoate and benzyl cinnamate. \\

Tolu balsam (Balsamum tolutanum, Tolubalsam) contains up to 80% resin and 1.5-3% essential oil. Main components found are benzoic acid (4.4-20.9%), cinnamic acid (6.1-12.9%), benzyl benzoate (4.3-12.8%), benzyl cinnamate (traces-3.6%). The balsam was formerly used in folk medicine as expectorant in case of bronchitis, externally to treat wounds.\\
