Botanical name: 

Akazga. Boundou. Quai. Ikaga. Icaya.—An ordeal poison, largely used in a district on the west coast of Africa, extending far into the interior, north and south of the equator. The precise botanical character of the plant is unknown, but it is thought to belong to one of the Loganiaceae. Thomas E. Eraser found in the plant an alkaloid, akasgine. The alcoholic extract or the alkaloid acts on the system similarly to nux vomica. (For further description, see U. S. D., 19th ed., p. 1373 and also A. J. P., March, 1867.)

The Dispensatory of the United States of America, 1918, was edited by Joseph P. Remington, Horatio C. Wood and others.
