PHYSIOLOGICAL ACTION.—Sanguinaria in toxic doses causes a train of 
symptoms showing it to be an irritant: it causes nausea, vomiting, sensations of 
burning in the mucous membranes whenever it comes in contact with them, faint- 
ness, vertigo, and insensibility. It reduces the heart's action and muscular 
strength, and depresses the nerve force, central and peripheral. Death has occurred 
from overdoses, after the following sequence of symptoms: violent vomiting, 
followed by terrible thirst and great burning in the stomach and intestines, 
accompanied by soreness over the region of those organs; heaviness of the 
upper chest with difficult breathing; dilation of the pupils; great muscular 
prostration ; faintness and coldness of the surface, showing that death follows 
from cardiac paralysis. (Allen, Ency. Pure Mat. Med., viii, p. 481, e¢ seq.)
