Definition of "camboge"

At the ordinary temperature of the air camboge has little smell, but when heated it gives out a very peculiar one. Taken into the mouth it has scarcely any perceptible taste, but upon being chewed for some time it causes a sharp, somewhat acrid feeling, ending in a sweet sensation, accompanied with dryness in the mouth. […] Camboge is more extensively used as a pigment than as a medicine.
