Chapter 24: Seed Plants I: Gymnosperms

Economic Importance of Conifers
Thick, sticky resin obtained from certain conifers yields rosin and turpentine when distilled properly. Rosin, used in everything from chewing gum to insulating material, and turpentine, used in paint solvents and cleaning agents, are two key economic products derived from conifers. The Food and Agricultural Organization of the United Nations provides information on the technical and economic aspects of resin production and on the production of gum turpentine and gum rosin-- known as gum naval stores.
