Lore | A native of the woodland areas of the Eastern United States. Native Americans used the roots to create a remedy for snake bites, leading to the common name of snakeroot. Early settlers were unaware of the poisonous properties of the plant, and would occasionally suffer from a poisoning they called milk sickness, caused by ingesting the milk or meat of a cow that had eaten the plant. Abraham Lincoln's mother, Nancy Hanks Lincoln, died of milk sickness in 1818. |
