the analysis of Pelzett, it contains euphorbia, 
acid resin andstarch. It isa diaphoretic, cath- 
artic and emetic; but is rarely used except in 
domestic practice. When given it is usually in 
doses of from ro to 20 grains (0.06 to 1.3 grams). 
All this genus of plants yield a milky juice, and 
many of the species are leafless. 
Euphorbia Ipecacuanha. Natural order 
Euphorbiacez. - Common names, Carolina Ipe- 
cac, American Ipecac, Ipecacuanha Spurge, etc. 
A tufted, shrub-like perennial plant attaining a 
height of 2 to 3 feet (60 to 90 centimeters) and, 
as the name implies, conspicuous for its showy 
false catkins of leaves, which appear like white 
petals. Its flowers are on long peduncles and 
in umbels. The leaves are obovate, oblong, 
lanceolate or linear, with very short petioles. 
According to analysis it contains euphorbia or 
euphorbin, caoutchouc, resin, starch and a color- 
ing matter, besides euphorbic acid. This genus 
of Euphorbia differs very much in the shape 
and color of its leaves and may, unless care be 
exercised, be taken for some other variety of 
the family. The root is irregular, yellowish, 
large, and frequently extends as much as six 
feet under the ground. This native plant is 
found in the barren pine regions of the South- 
ern and Middle States, also along the sandy 
seaboard of Delaware and New Jersey. 
The ipecacuanha spurge is comparatively a 
certain emetic; unfit, however, to supersede 
ipecacuanha, though milder in its effects, it 
is apt to act violently on the bowels.
