and root have stimulant properties, and are applied externally 
to parts bitten by venomous animals; the leaves are given 
raw in dysentery, and are also applied externally to cure 
eruptions. (Hoxb.) An infusion of the toasted leaves, accord- 
ing to Ainslie, is used by the Hindus to stop vomiting. The 
plant is noticed in the Pharmacopeceia of India as having tonic 
and stomachic properties. The leaves are much used as an 
ingredient in sauces and are sometimes given in decoction 
with bitters as a febrifuge. Judging by the Marathi names,

Description.—The leaves are pinnate with numerous 
leaflets which are 14 inch to 2 inches long, alternate, unequally 
Oblique at the base, irregularly ovate, serrated, pubescent, 
upper surface dark green, dotted, under surface of a lighter 2

spread widely and send up numerous suckers; they have a 
_ thick soft bark, the parenchyme of which is loaded with oil 
_ globules. It has an agreeable odour and taste like fresh : 
‘ginger. ; 
The leaves yield to distillation a small quantity of ier 
oil resembling that obtained from the leaves of a 
armelos. 
Chemical composition.—As a considerable quantity, 28 — 
pounds, of the leaves had been previously distilled with water 
and yielded only a few drops of oil, it was not thought nce 
to extract with petroleum ether. A weighed quantity, 80 
grams, of the sun-dried and powdered leaves was exhauste ¢ 
with ether, and a measured quantity evaporated, dried ‘a1 
weighed, yielded a greenish-black resin equivalent to 74 
cent. of the leaves. The bulk of the ethereal extract 
allowed to evaporate by exposure to the air, and the r sidt
