Discussion: In the 1900’s many pioneers died of milk sickness. One such notable victim was Nancy Hanks Lincoln, who died of the “milk sickness” when her son, Abe was only 7. The pioneer woman, Dr. Anna Pierce, correctly identified White Snakeroot as the cause of “trembles” in cows, and milk sickness in people who drank milk or ate meat from these cows. Dr. Pierce urged the eradication of white snakeroot. The toxicity of white snakeroot does, however, vary greatly according to region and moisture.

 

Distribution:  It grows at the edge of the forest.
