> Milk sickness, also known as tremetol vomiting, is a kind of poisoning characterized by trembling, vomiting, and severe intestinal pain that affects individuals who ingest milk, other dairy products, or meat from a cow that has fed on white snakeroot plant, which contains the poison tremetol. In animals it is known as trembles.

> Although very rare today, milk sickness claimed thousands of lives among migrants to the Midwestern United States in the early 19th century, especially in frontier areas along the Ohio River Valley and its tributaries where white snakeroot was prevalent. New settlers were unfamiliar with the plant and its properties. Nancy Hanks Lincoln, the mother of Abraham Lincoln, is said to have been a victim of the poison. Nursing calves and lambs may have also died from their mothers' milk contaminated with snakeroot even when the adult cows and sheep showed no signs of poisoning. Cattle, horses, and sheep are the animals most often poisoned.

Nice, Fresh, Honest Milk.
