This gum, which exudes from the tree's bark and branches before hardening in the air, typically appears in smooth, yellowish-white oval or cylindrical pieces, exuding a balsamic odor reminiscent of turpentine. Upon heating, it releases a mildly aromatic and slightly bitter taste. Primarily utilized in the formulation of specialist lacquers, plasters, and dental fillings, Sandarac gum comprises approximately 95% resin substances, which include diverse free resin acids such as sandaracopimaric and callitrol acids. Furthermore, it contains a small proportion of bitter constituents and essential oils, featuring compounds like Alpha- and Beta-Pines, D-Limonene, and thymoquinone.
