Common Ladyfern

Athyrium filix-femina

Athyrium filix-femina, commonly known as Lady Fern, is a traditional plant found in various temperate regions worldwide. While it has not been traditionally used for medicinal purposes, studies have shown that its stomatal responses are regulated by leaf hydraulics rather than metabolism. Scientific evidence also indicates that Athyrium filix-femina can accumulate mercury and other trace elements like Ba, Cd, Hg, Mo, Mn, Ni, Zn, and lanthanides, with varying levels depending on the ecosystem, particularly in areas near former mining sites. Notably, fern rhizomes from related species such as Dryopteris filix-mas and Matteuccia struthiopteris have been used traditionally in Norway for additional fodder. Safety concerns are minimal, with no major issues recorded; similarly, there is no reported evidence of drug interactions associated with this plant.
