Gamboge is a rather transparent dark mustard yellow pigment. In biology, pigment is any material resulting in color in plant or animal cells which is the result of selective absorption. ...
Gamboge is most often extracted by tapping from the Garcinia hanburyi tree. The trees must be 10 years old before they are tapped. The resin is extracted by making spiral incisions in the bark, and by breaking off leaves and shoots and letting the milky yellow resinous gum drip out. The resulting latex is collected in hollow bamboo. After the latex is congealed, the bamboo is broken away and large rods of raw gamboge remain.
