an aromatic gum resin, is obtained by incising the bark of certain trees (Conifers). The fluid hardens into irregular lumps covered with white dust. It has a yellow or yellowish-brown color, a bitter aromatic taste, and a balsam-like odor. It is insoluble in water and burns with a white flame. As a drug it was widely used in all kinds of inflammatory diseases, but is little used now except for external application. It has been employed from the earliest times in incense.
