Welcome in July w/theme new gamboge
Gamboge or gummi gut is dark yellow in color. The gamboge tree is native to Asia. From there, gamboge was imported into Europe from the 17th century. Gamboge or gummi gut is extracted from the resin of the gamboge tree. The bark of the tree is notched so that the milky sap can drain from the tree.
The name 'gamboge' is probably a corruption of 'Cambodia', the country where the gamboge tree grows, among other things.
