Little information is available about the use of polypodium in children and safety is not clear.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


People with allergies to ferns (family Polypodiaceae) should avoid polypodium.

Side Effects and Warnings

Isolated reports of itching or stomach upset are published. Studies of a different fern species, Polypodium vulgare, report sedation, changes in heart function in animals, low blood pressure, and rapid heart rate. Avoid driving and use of heavy machinery when taking Polypodium leucotomos extract due to theoretical sedative effects. People with heart disease or those being treated for heart disorders or high blood pressure should use caution.

Pregnancy and Breastfeeding

The use of polypodium during pregnancy or breastfeeding is not recommended because there is little information about its safety.
