Aspidium Sw. is a fern genus in the Dryopteridaceae (wood fern) family. Although the genus name itself it is now generally considered to be obsolete and a synonym for Tectaria Cav. (in the Tectariaceae family),[1] Aspidium's former species have been placed in several other families and genera.

The name aspidium is also used in referring to a medicine, usually in the form of an oleoresin extract, containing filicin, made from the rhizomes and stipes of certain former Aspidium species such as Dryopteris filix-mas (male fern), and Dryopteris marginalis (marginal fern). These medicines have been used in the treatment of tapeworm infection, but their use is limited to otherwise-untreatable cases due to the toxicity of the medication. Safer drugs such as dichlorophen, niclosamide, and quinacrine are preferred.


Most Aspidium species have been recategorized into other genera, including:[1]
