The sword fern is known for purifying the air of toxic substances such as formaldehyde and xylene. That's why it's often in offices, for example. But is it actually non-toxic or does it contain toxins?
Is the sword fern poisonous?
The sword fern is classified as slightly toxic and does not pose any significant danger to humans or animals. Compared to other fern species, such as the highly toxic bracken, the sword fern is largely harmless and does not cause any allergic reactions.
Low toxic – poisoning unlikely
Experts describe the sword fern as 'low poisonous'. This applies to both people and animals. This property distinguishes it greatly from many other ferns such as bracken, which is considered highly toxic. Skin contact does not trigger any allergic reactions.
Basically, the sword fern is largely harmless. If your child or pet tries something from this plant, there is no need to worry. If too much has been consumed, the body usually gets rid of the toxins on its own by triggering vomiting.
Tip
Plant the easy-care sword fern in hanging baskets (€13.00 on Amazon), which you attach to the ceiling of the bathroom, for example. This is out of the reach of cats, dogs and small children.
