Podophyllum peltatum (Mayapple)
This plant has been used to treat warts, while the roots were used to treat jaundice, fever, liver ailments, and syphilis. The Mayapple is still used today in folk medicine in some areas of the Appalachian Mountains.
A tea can be made from the roots, and is used to treat constipation.
Mayapple is being tested as a possible treatment for cancer as it contains podophyllin, which has an antimiotic effect that interferes with cell division, which may slow or even prevent the growth of cancer cells.
