    • n tabasheer A white opaque or translucent variety of opal which breaks into irregular pieces like dry starch, found in the joints of the bamboo in the East and Brazil, and believed to be caused by disease or injury to the plant. It possesses the power of absorbing its own weight of water, when it becomes entirely transparent. It is probably the “oculus mundi” of the gem-writers of the sixteenth, seventeenth, and eighteenth centuries. In the East Indies tabasheer, prepared by calcining and pulverizing, is largely used as a medicine by both Hindus and Mohammedans; it is esteemed cooling, tonic, aphrodisiac, and pectoral.
