Gamboge (/ɡæmˈboʊʒ, -ˈbuːʒ/ gam-BOHZH, -BOOZH) is a deep-yellow pigment derived from a species of tree that primarily grows in Cambodia. Popular in East Asian watercolor works, it has been used across a number of media dating back to the 8th century.: 144 Easy to transport and manipulate into a durable watercolor paint, gamboge is notable for its versatility as a pigment in how it has been used in paintings, printing of books, and garment dyes, including the robes of Buddhist monks. Gamboge is toxic to humans, and is potentially deadly in larger doses. Due to its toxicity and poor lightfastness, gamboge is no longer used in paints, though limited use continues in other contexts. Though used in a number of different contexts, Gamboge is known not to react well with citric acid surfaces therefore making it unsuitable for frescos and with white lead.: 147 For its popularity, Gamboge has not been extensively identified in works of art from any time period; the few instances wherein art historians have attempted to identify whether or not the pigment was used in a given work have confirmed its widespread use and its longevity as staple within watercolor painting particularly in eastern art.: 170
