Copalchi Bark

Copalchi Bark, a bark resembling Cascarilla Bark (q.v.) in its properties, and produced by a shrub of the same genus, Croton niveus, a native of Central America (see CROTON). The bark is in quills a foot or two in length, and has a thin corky epidermis. Copalchi Bark is much used as a substitute for cinchona in Mexico, where it goes by the name of Quina blanca, and is imported, although not to a large extent, into Europe. It contains a minute proportion of a bitter alkaloid resembling quinine.
