Gamboge \Gam*boge"\, noun A concrete juice, or gum resin, produced by several species of trees in Siam, Ceylon, and Malabar. It is brought in masses, or cylindrical rolls, from Cambodia, or Cambogia, -- whence its name. The best kind is of a dense, compact texture, and of a beatiful reddish yellow. Taken internally, it is a strong and harsh cathartic and emetic. [Written also {camboge}.]

Note: There are several kinds of gamboge, but all are derived from species of {Garcinia}, a genus of trees of the order {Guttifer[ae]}. The best Siam gamboge is thought to come from {Garcinia Hanburii}. Ceylon gamboge is from {G. Morella}. {G. pictoria}, of Western India, yields gamboge, and also a kind of oil called gamboge butter.
