Gamboge \Gam*boge"\, n.
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}.]
[1913 Webster]
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. Gambogian
