    Description of the substance

    A small tree or shrub with a few spreading branches bearing alternate petiolate leaves which are ovate, acuminate, serrate, smooth, dark green on upper surface paler beneath and furnished with two glands at base. Flowers in erect terminal racemes, scarcely as long as the leaf, the lower female, upper male, straw-coloured petals. Fruit a smooth capsule of the size of a filbert, three cells, each containing a single seed; these seeds resemble castor beans in size and structure, oblong, rounded at the extremities with two faces; the kernel or endosperm is yellowish brown and abounds in oil. The oil is obtained by expression from the seeds previously deprived of the shell.

    Tolerates drought, insects and poor soil. Tolerates a range of environments from subtropical moist to tropical very dry, and up to 1500 metres above sea level.

    Wide spread throughout the Phillipines. Found in Indonesia and as far north as China. Grown in Southen California as an ornamental and curiousity plant.

    Croton Tiglium Willd. is a small tree or shrub, with a few spreading branches, bearing alternate petiolate leaves, which are ovate, acuminate, serrate, smooth, of a dark-green color on the upper surface, paler beneath, and furnished with two glands at the base. The flowers are in erect terminal racemes, scarcely as long as the leaf—the lower being female, the upper male—with straw-colored petals. The fruit is a smooth capsule, about the size of a filbert, with three cells, each containing a single seed.

    The seeds of the C. Tiglium resemble castor beans in size and general structure. They are oblong, rounded at the extremities, with two faces, the dorsal considerably more convex than the ventral, separated from each other by longitudinal ridges, and each divided by a similar longitudinal ridge, so that the whole seed presents an irregular quadrangular figure. Sometimes their ventral surface is flat, with a longitudinal groove, owing to the presence of only two seeds in the capsule, the groove being produced by the central column or axis. The shell is covered with a soft, yellowish-brown epidermis, beneath which the surface is black and smooth, and, as the epidermis is often partially removed by friction during their carriage, the seeds as they come to us are frequently mottled, and sometimes nearly black. The kernel or endosperm is yellowish-brown, and abounds in oil. In India the seeds are prepared for use? by submitting them to slight torref action, by which the shell is rendered more easily separable. In the dose of one or two grains (0.065 or 0.13 G-m.) the kernel purges severely.

    The oil is obtained by expression from the seeds, previously deprived of the shell. It may also be separated by decoction in water, or by the action of ether, or carbon disulphide, which dissolves the oil and leaves it behind when evaporated. Guibourt recommends, after the first expression, to digest the residue with alcohol at a temperature of 48.8° to 60° C. (120°-140° F.), and then submit it to a new expression. The. alcohol is to be separated by distillation from the oil, which is then to be mixed with the first product. Great care must be used, during this distillation, to prevent blistering the unprotected skin of the operator.
