Dragon’s blood is a resin produced by the rattan palm tree, Daemonorops draco. Native to Southeast Asia, Dragon's Blood appears in tropical and subtropical climates and occurs on the Malay Archipelago, specifically cultivated in Sumatra. There are in fact many red resins colloquially known as dragon’s blood, many of which possess different properties and come from entirely different plants. The resin of Daemonorops draco is the most commercially available, and is the species provided by Mountain Rose Herbs.
Dragon’s blood resin is often burned as an incense, and its deep red pigment is used as a varnish and a dye. The resin is still used today in modern witchcraft where it is powdered down and used as an ink to write spells.
