Euphorbia Exiqua, Euphorbia Mauritanica, Euphorbia Netifolia, 
and Euphorbia E,sula. We are told by Scapuli, that this last 
species produced death in a woman, in half an hour after she had 
swallowed thirty grains of the root. The same author witnessed 
gangrene and death to follow the application of Euphorbia Esula to 
the abdomen. 
Several different species of Euphorbia have also been used medi- 
cinally, viz. the Euphorbia Ipecacuanha, which, in doses of from 
ten to fifteen or twenty grains, generally proves emetic, and acts 
without much violence. The Euphorbia CoroUata is a pretty 
certain purgative, in doses of from five to ten grains, double the 
quantity proves emetic. The juice of the Euphorbia Helioscopia 
proves an useful application for destroying warts. The seeds of the 
Euphorbia Lathyrus are emetic, and have been proposed as a 
substitute for ipecacuanha, and the oil expressed from them is 
powerfully cathartic.
