Healing properties:

In the past, the excercises of the fern rhizomes were used in many pharmacopoeias and were used to combat intestinal parasites and especially against tapeworms. Nowadays, this recommendation has been dropped.


Preparations from the fern root have vermifuge action.

The active principles of fern rhizomes have the property of paralyzing the muscles of the skin, as well as other intestinal parasites (botrycephalus, ascaris, anchilostoma).
