Hart's-Tongue Fern - the Medicinal Fern
Table of Contents
The plant "Asplenium scolopendrium", known in Bulgaria as volski ezik ("ox tongue") and in English as hart's-tongue fern, is an evergreen fern of the genus Asplenium with exceptional health benefits.

Hart's-tongue fern is an evergreen plant. We come across it in shady spots in deciduous forests, and it is very good to be familiar with its medicinal properties.
"Ox tongue", "deer tongue" or "buffalo tongue" are just some of the names our people have given this miraculous herb. It seems, however, that over the years we have forgotten its properties, displaced by chemical substances, which is why we want to introduce you to it.
#Botanical characteristics
Hart's-tongue fern looks like a traditional fern with simple, undivided fronds. They are 10-60 cm long and 3-6 cm wide.
They are also characteristically hairless, entire, linear-lanceolate and slightly wavy at the edges. They are heart-shaped at the base, with long stalks growing straight from the rhizome. Their shape strongly resembles an ox's tongue, which is where the Bulgarian name comes from.
#Folk names of the herb in other countries
English - Hart's-tongue fern, Russian - Олений язык, German - Hurschzungenfarn, French - langue de cerf.
#Distribution
"Asplenium scolopendrium" is a common diploid species in Europe. In North America it occurs in rare, widely scattered populations.
The herb grows on neutral and lime-rich substrates, including moist soil and damp crevices in old walls, most often in shady areas. Plants exposed to more sunlight are usually stunted and yellowish, while those in full shade are dark green and lush.
In the USA the plant was declared endangered in 1989. The reason why the European variety is relatively widespread while the American one is rare has not yet been established. A third variety, A. scolopendrium var. lindenii, occurs in southern Mexico and Hispaniola.
#Cultivation
Hart's-tongue fern is often grown as an ornamental plant, with several cultivars selected for different leaf shapes. The species "Asplenium scolopendrium" has won the Royal Horticultural Society's Award of Garden Merit in the UK, as has the cultivar 'Angustatum'.
The American variety is thought to be difficult to grow, and even in North America most, if not all, cultivated plants are derived from the European forms.
