(n.) A tough, white, aromatic resin, or gum, obtained from different species of the Laurus family, esp. from Cinnamomum camphara (the Laurus camphara of Linnaeus.). Camphor, C10H16O, is volatile and fragrant, and is used in medicine as a diaphoretic, a stimulant, or sedative.
(n.) A gum resembling ordinary camphor, obtained from a tree (Dryobalanops camphora) growing in Sumatra and Borneo; -- called also Malay camphor, camphor of Borneo, or borneol. See Borneol.
