Fern plants are a popular choice for indoor and outdoor gardens due to their beautiful, intricate foliage and low maintenance requirements. However, there is a common misconception that ferns are toxic to humans.

In this article, we will explore the truth behind this myth and discuss the safety of fern plants for both humans and pets.

Toxicity of Ferns: The Facts

Contrary to popular belief, most ferns are not toxic to humans. In fact, many fern species have been used for centuries in traditional medicine to treat a variety of ailments. For example, the fiddlehead fern, which is the curled-up frond of certain fern species, has been used to treat inflammation and boost the immune system.

However, it is important to note that some fern species do contain toxins that can be harmful to humans and pets if ingested. These toxins are usually found in the sap or rhizomes (underground stems) of the fern and can cause symptoms such as nausea, vomiting, and diarrhea.

It is important to be cautious when handling these ferns and to keep them out of reach of children and pets.
