|Xue Jie in "extract form" is composed of finely ground powder. This is because Xue Jie is the resinous sap of the Daemonorops draco palm fruit. Resins are hydrocarbon secretions of plants and are therefore already extracted from their plant origins. Powders are made from these extracted resins by removing the volatile terpene components by distillation and are then known as rosins. They cannot be further concentrated.
