A small tree, 3—7 m tall with a rather crooked trunk but smooth bark; branches slender,<br />
smooth, terete, bark paler, whitish-brown, marked with scars of fallen leaves; leaves simple,<br />
alternate, on stalks nearly half as long as the blade which is about 8—14.5cm long, 4.5—7 cm<br />
broad, thin, glabrous, ovate, faintly and rather distantly serrate, bright green,<br />
veins prominent beneath, petioles breaking up immediately on entering the leaf into 5 veins,<br />
the two lateral ones faint, the two intermediate well marked, giving with the midrib a triplenerved<br />
aspect of the leaf; on either side of the base of the blade and connected with the petiole<br />
is a prominent sessile gland; stipules minute, filiform, deciduous; young leaves and buds wuh<br />
scattered stellate hairs; flowers unisexual in lax, terminal, erect racemes, the male flowers on<br />
the upper part of the raceme, the female less numerous on the lower part, pedicels longer than<br />
the flowers, bracts minute; male flowers yellowish, about 7 mm in diameter, calyx of<br />
5 spreading, broadly triangular, blunt sepals 2.5 mm long, 1.5 mm broad, valvate, apices pubescent;<br />
petals 5, inserted on the flat receptacle, alternate with and reflexed between sepals, 2.5 mm<br />
Jong, 0.7 mm broad, oblong—linear, blunt, set with rather long white hairs above, glabrous<br />
beneath, whitish; a prominent roundish yellow gland stands within each sepal, alternating with<br />
the petals; stamens 14—20, as long as petals, one opposite each petal and sepal, the remainder<br />
irregularly dispersed over the receptacle which is covered with short, white hairs, anthers small,<br />
broad, innate, cells semilunar; female flowers about 3 mm across, dark green; calyx deeply<br />
5-partite, divisions 2 mm long, 0.7 mm broad, ovate, acute, tipped with hairs, spreading or<br />
reflexed, set with few or more numerous stellate hairs and with a small, rounded prominence<br />
at the angle between each, glands 5, blunt, prominent, opposite the sepals as in male flowers,<br />
petals absent; ovary sessile, 1 mm long, thickly covered with stellate hairs, 3-locular with a<br />
single pendulous ovule in each loculus, styles 3, bifid; fruit slightly inflated, pale, smooth,<br />
brownish-yellow, capsular with a single, large seed inside each chamber; seeds albuminous,<br />
1.2 cm long, 1 cm wide, ovoid, rounded at the back, marked on the ventral surface by a fine<br />
raised raphe, testa thin, brittle, light-brown.<br />

Composition. The seeds possess a fixed oil which contains croton globulin and croton<br />
albumen, arginine and lysine; alkaloid vicinine; lipase; invertase, amylase, raffinase; proteolytic<br />
enzyme, croton resin, tiglic acid, croton oleic acid, stearic, palmitic, myristic, lauric, oenanthrallic,<br />
capronic, valerianic, butyric, isobutyric, acetic and formic acids; tannin, etc.<br />
Uses. The roots, leaves, bark and seeds possess drastic purgative properties. The<br />
bruised root is applied to carbuncles and cancerous sores. The seeds are poisonous and are a<br />
powerful and drastic purgative. The oil extracted from the seeds applied externally is a counterirritant<br />
and a liniment prepared from it, is useful in rheumatism, glandular and other<br />
swellings, chronic bronchitis and other pulmonary affections. The oil is also useful in dropsy,<br />
intestinal obstructions and lead poisoning. The seeds and leaves are used for poisoning fish<br />
by the Dayaks of Borneo and in the Philippine Islands. The leaves are one of the constituents<br />
of the Batak arrow poison.<br />
The oil is a very valuable cathartic and it acts speedilly and powerfully on the bowels.<br />
In Ceylon, the seed is used along with other drugs in fever, constipation in dropsy and as a<br />
drastic purgative for colic, ascites, etc.,<br />
