The isomer from Dryobalanops is dextrorotatory; the levoratatory form is obtainable from other species of plants, and the racemic mixture may be obtained by reduction of camphor. It is used in perfumery, and for manufacture of its esters. See Borneol. [1913 Webster +PJC] Note: The name camphor is also applied to a number of bodies of similar appearance and properties, as cedar camphor , obtained from the red or pencil cedar (Juniperus Virginiana), and peppermint camphor, or menthol, obtained from the oil of peppermint. [1913 Webster] Camphor oil (Chem.), name variously given to certain oil-like products, obtained especially from the camphor tree. Camphor tree, a large evergreen tree (Cinnamomum Camphora ) with lax, smooth branches and shining triple-nerved lanceolate leaves, probably native in China, but now cultivated in most warm countries.

[1913 Webster +PJC] Note: In the 1913 Webster eucalytpol was defined as an oil “consisting largely of cymene”. Cymene (isopropyltoluene, C10H14) differs from that of the substance currently called eucalyptol, in having an unsaturated ring and no oxygen. Para-cymene does occur in eucalyptus oil as well as some other essential oils. [PJC] ||
