Male Fern

How does Male Fern 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.

Are there safety concerns?

Male fern is UNSAFE. It is a violent poison and should not be taken by mouth. In fact, Canada requires that male fern products be labeled "For external use only." Since there are other products available that are effective and safer than male fern, there is no reason to use it.

Side effects caused by taking male fern can be serious and include breathing difficulty, nausea, diarrhea, dizziness, headaches, tremors, convulsions, heart and lung failure, eye disorders, muscular weakness, coma, temporary or permanent blindness, and death.

Treatment of overdose consists of giving salt water followed by other special fluids. It is important to avoid fats and oils because they increase the amount of male fern that is absorbed by the body. If seizures occur, benzodiazepines may be used, and a breathing machine may be necessary.

Special Precautions & Warnings:

Male fern shouldn't be used by anyone. Some people may be at even higher risk of side effects.

Pregnancy and breast-feeding: Male fern is UNSAFE for anyone to take as medicine. If you take it while pregnant or breast-feeding, you will endanger yourself as well as your baby.

Stomach and intestinal conditions: Stomach and intestinal conditions that increase digestion time might increase the amount of male fern that is absorbed in the intestine. This bigger dose of male fern could lead to more serious side effects.

Dosing considerations for Male Fern.

The appropriate dose of male fern depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for male fern. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
