 trembling and progressive weakness. The latter does not cause

 found in the urine.

USES. The milky juice of the plant is emetic and purgative. 

 The chemist De Vry has isolated from it a poisonous alkaloid 

 analogous to " thevetin," which has just been considered. The 

 seeds are likewise emetic and toxic. The Javanese call the 

 fruit " bimaro " and affirm that it possesses the same properties
