Dragon's blood tree Dracaena cinnabari

Description

A transparent, red, resinous exudation from the fruit of several types of palms found in southeast Asia (Calamus draco, Daemonorops draco, Daemonorops propinquus, Dracaena draco and Dracaena cinnabari) and South America (Pterocarpus draco). Dragon's blood is available as red sticks, cakes, or as a powder. The primary red coloring component is dracorubin. It evolves benzoic acid when heated. Dragon's blood was traded as early as Roman times. It was used as a red colorant in medieval manuscript illuminations. Dragon's blood has been used to stain varnishes for violins and as a colorant for plaster, marble, and paints. The resin has also been used as a resist in photoengraving to protect zinc plates from acid. The red color is fugitive when exposed to light and air, but may be partially protected by a resin film layer.
