Bixby discovered that white snakeroot (Ageratina altissima) was the cause of milk sickness from grazing cows eating the wild plant which fatally poisoned the milk consumed by frontier settlers

Anna Pierce Hobbs Bixby, sometimes spelled Bigsby, born Anna Pierce (c. 1810 – c. 1870), was a midwife, frontier doctor, dentist, herbologist, and scientist in southern Illinois.[1]

Bixby discovered that white snakeroot (Ageratina altissima) contains a toxin. When cattle consume the plant, their meat and milk become contaminated and cause the sometimes fatal condition of milk sickness. One of the most notable and tragic cases of the "milk sickness" was that of Nancy Hanks Lincoln, the mother of Abraham Lincoln, who died at 34 years old in 1818.

Dr. Anna began to follow the grazing cattle, checking the plants they fed upon. One day while walking with the cattle through the woods, she happened to find an elderly Shawnee Indian medicine woman, who had been left behind by the tribe when they were scattered at the close of the War of 1812. Dr. Anna took the old woman into her home to care for her. After learning about the milk sickness plague and that Dr. Anna was so concerned, the elderly medicine woman took Dr. Anna into the woods and showed her the white snakeroot and told her that this was the plant causing the milk sickness.
