What is Male Fern?

Male fern is a very poisonous plant. Taking it by mouth can cause death. Despite these serious safety concerns, some people use the leaf and other parts that grow above the ground, as well as the underground stem (rhizome), to make medicine.

Male fern is used to treat nosebleeds, heavy menstrual bleeding, wounds, and tumors. It is also used to expel worms, typically tapeworms, from the intestines.

Some veterinarians use male fern to treat worms in animals.
