Balsam (also: turpentine) is the resinous exudate (or sap), which forms on certain kinds of trees and shrubs. Balsam (from Hebrew bosem בֹּשֶׂם, "spice", "perfume") owes its name to the biblical Balm of Gilead.
Balsam is a solution of plant-specific resins in plant-specific solvents (essential oils). Such resins can include resin acids, esters, or alcohols. The exudate is a mobile to highly viscous liquid and often contains crystallized resin particles. Over time and as a result of other influences the exudate loses its liquidizing components or gets chemically converted into a solid material (i.e. by autoxidation).
- pure resins (guaiac, hashish),
- gum-resins (containing gums/polysaccharides),
- oleo-gum-resins (a mixture of gums, resins and essential oils),

Balsam of Mecca
The liquid balsam called Balsam of Mecca is extracted from the tree Commiphora gileadensis (synonym: Commiphora opobalsamum) It is designated in the Bible by various names: bosem, besem, ẓori, nataf, and, in rabbinic literature, kataf, balsam, appobalsamon, afarsemon. It was used as a perfume and as a drug.
It was extracted both as the volatile component of the sap of the tree, and by boiling the stems and leaves. It was the only tropical, and the most expensive, spice grown in Israel. It was known to Pliny (Historia Naturalis 12:116; 13.18) as opobalsamum.
