Overview

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.

People use male fern for conditions such as rheumatoid arthritis, infection of the intestines by parasites, and many others, but there is no good scientific evidence to support these uses. There is also concern that taking male fern can cause severe side effects.

Some veterinarians use male fern to treat worms in animals.

How does it work ?

Male fern contains chemicals that can kill intestinal worms such as tapeworms. Once the worms have been killed, salt water (saline) is taken to flush them from the body.
