PHYSIOLOGICAL ACTION.—When taken in large doses hydrastis causes a 
train of symptoms due to a hyper-secretion of the mucous membranes. If per- 
sisted in, it causes severe ulceration of any surface it may touch; and a catarrhal 
inflammation of mucous surfaces, followed by extreme dryness and fission. It 
causes also a catarrhal inflammation of the mucous linings of the hepatic ducts 
and gall-bladder—showing in an icteric hue of the skin—and a similar condition 
of the bladder, catarrhal cystitis. -
