Coca. (Erythroxylon Coca.)

Coca. Lineae (suborder Erythroxyleae).

Nearest related to the Malpighiaceae and Sapindaceae, next to the Aceripaceae and the Rhizoboleae.

A bush six or eight feet high, small white flowers and bright green leaves. The leaves are two and half inches long and half as wide; the characteristic sign of the leaf is an arched line on each side of the midrib. Coca was first used in the United States as a tobacco antidote. It is known to have been in use with the Peruvians since the Conquest. In the time of the Incas the Coca was regarded as sacred. It is largely cultivated in Bolivia for the sake of its leaves, which are much used in that country for chewing. In 1856 the sale of the leaves secured an income to the Republic of thirteen million francs. It is now in general use among the Indians as a narcotizing beverage. The plant, which is propagated from the seed in nurseries, begins to yield in eighteen months and continues productive for half a century.

In 1856 it was proved by Clotar Müller, Hom. Viert., vol. 7, p. 443. Proving by Stokes, in Mon. Hom. Rev., vol. 3, p. 275, in 1859. Provings were suggested in 1867, by W. S. Searle, in N. A. J. of H., vol. 16, p. 1, and made in the same year by Berridge, Croker, Ray and Scheibler. Other provings were made, in 1869, by Lilienthal, Safford, Williams, Ferguson and Labeau. In 1870, C. Hering made a complete arrangement of the effects, from all available sources, in the form of a monograph, for the Journal of Materia Medica.
