Used as a masticatory substance; [FDA] "Terpenes are a large and diverse class of organic compounds, produced by a variety of plants, particularly conifers, . . . The difference between terpenes and terpenoids is that terpenes are hydrocarbons, whereas terpenoids contain additional functional groups. They are the major components of resin, and of turpentine produced from resin. . . . Terpenes are derived biosynthetically from units of isoprene, which has the molecular formula C5H8. The basic molecular formulae of terpenes are multiples of that, (C5H8)n where n is the number of linked isoprene units." [Wikipedia]
