164-3 
As far as I can determine, this tree has not been specifically examined as to 
its constituents. 
PHYSIOLOGICAL ACTION.— Abies Canadensis causes, according to 
Gatchell,* vertigo and weakness; great hunger, with burning and distention of 
the abdomen; thirst; increased heart’s action; restlessness and chilliness; the 
urine is increased and of a straw-color. The drug appears to cause a torpor 
of the liver, resulting in a diminished secretion of bile, pain in the right shoulder- 
blade, and constipation.
