Coscinium. Br. Add.—The dried stem of Coscinium fenestratum Colebr. The stem of this menispermaceous plant has long been used in Ceylon and Southern India as a yellow dye and bitter tonic, and has found its way into Europe under the names of false columba and tree turmeric. It almost certainly contains berberine and is an efficient stomachic. The Br. Add. recognized an infusion (Infusum Coscinii. Br. Add.), dose, one-half to one fluidounce (15-30 mils); a concentrated solution (Liquor Coscinii Concentratus, Br. Add.), dose, one-half to one fluidrachm (1.8-3.75 mils); and a tincture (Tinctura Coscinii, Br. Add.), dose, one-half to one fluidrachm (1.8-3.75 mils).
