| | US Dispensatory, 1918: CAMBOGIA. U. S. |
 | | The inferior kinds of gamboge may be known by their greater hardness and coarser fracture; by the brownish or grayish color of their broken surface, which is often marked with black spots; by their obvious impurities, and by the green color which their decoction, after cooling, gives with tincture of iodine (starch). |
 | | According to Beckett, Siam gamboge is obtained only from trees of not less than ten years of age and during the rainy months, from June to October, by cutting long, spiral grooves into the bark and collecting in hollow bamboos the sap which trickles down in a viscous stream. |
 | | Gamboge is said to be procured in Siam by breaking off the leaves and shoots of the tree; the juice, which is contained in ducts or latex vessels in the bark, issues in drops, and, being received in suitable vessels, gradually thickens, and at length becomes solid. |
