What does spleenwort mean?
Spleenwort is a botanical name for ferns in the genus Asplenium, most commonly referring in British usage to black spleenwort, Asplenium adiantum-nigrum, and in some contexts to maidenhair spleenwort, Asplenium trichomanes. The name is a striking example of the doctrine of signatures, an early modern belief that plants resembling parts of the body could be used to treat corresponding illnesses. The small, round sori on the undersides of certain spleenwort fronds were thought to resemble the spleen, so the plant came to be associated with remedies for splenic disorders. Today the word occurs chiefly in botanical, horticultural, and nature-writing contexts rather than general conversation. Because several Asplenium species have received the name, spleenwort should generally be treated as a group term unless a particular species is specified. Its combination of attractive fern foliage and an unusual medicinal-sounding name makes it memorable in gardens, field guides, and historical writing.

Where does spleenwort come from?
Spleenwort is an English compound formed from spleen and the Old English word wyrt, meaning “plant” or “herb.” Spleen entered English through Old English from Latin splen, which was borrowed from Greek splēn, while the plant name arose because its sori were believed to resemble that organ under the doctrine of signatures. Related English words such as splenic and splenomegaly continue to reflect the same Greek and Latin root.
How spleenwort is actually used
This is primarily a botanical term, especially in British and American naturalist and horticultural usage. It is an uncommon collective name rather than a precise designation for one species, and its historical medicinal associations do not imply any established medical value.
