White snakeroot
White snakeroot is generally found in woods and along streams.  It is not often found on open prairies because it does not do well in full sunlight.  The plant will grow 1 to 3 feet in height and will have thin smooth leaves with toothed margins.
	The flowers of this plant are white and disc-shaped.  White snakeroot is poisonous to most warm-blooded animals including humans.  The poisonous effects in livestock usually result from direct consumption of the white snakeroot plants.  In humans, poisoning can be caused by consumption of dairy products from cows that have eaten white snakeroot.  In fact, Abraham Lincoln's mother died after drinking milk from a cow that had eaten white snakeroot.  Symptoms of White snakeroot poisoning in livestock are listlessness, weight loss, appetite loss, labored breathing and possibly death.  Humans who are poisoned by this plant will have digestive disorders, lower than normal body temperature, and the victim will have the odor of acetone on their breath.
