Capulincullo.—This drug, derived from the Rhamnus Humboldtianus Roem. and Schult. (Fam. Rhamnaceae) of Mexico, is said to be a violent poison, acting like curare. A non-toxic, non-drying fixed oil, tasteless and odorless, is obtained in considerable quantities from the fruit of the tree.

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