Polypodium vulgare

Common name: Polypody Family: Polypodiaceae
Author: L. Botanical references: 17, 200
Synonyms:  
Known Hazards: Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200]. Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[172].
Range: All of Europe, the Mediterranean, temperate Asia and eastern N. America.
Habitat: Rocks, walls and trees, as well as on the ground, in a variety of habitats[187] but especially in humid shady conditions[31].

An evergreen fern growing to 0.3m by 0.3m . It is hardy to zone 3. It is in leaf all year. We rate it 3/5 for edibility and 3/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay and nutritionally poor soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) or semi-shade (light woodland). It requires dry or moist soil.

Habitats and Possible Locations

Woodland, Dappled Shade, Shady Edge, Deep Shade, Walls, Ground Cover.

Edible Uses

Root.

Root. Very sweet, it contains sugars, tannin and oils[13]. It is used as a liquorice adulterant[7]. The root has a unique, rather unpleasant odour and a sweet (cloying) flavour at first though it quickly becomes nauseating[222]. The root contains 15.5% saccharose and 4.2% glucose[218].

Medicinal Uses

Disclaimer

Alterative Anthelmintic Cholagogue Demulcent Diuretic Expectorant Pectoral Purgative Tonic.

Polypody stimulates bile secretion and is a gentle laxative. In European herbal medicine it is traditionally used as a treatment for hepatitis and jaundice and as a remedy for indigestion and loss of appetite[254]. It should not be used externally since it can cause skin rashes[254].
The root is alterative, anthelmintic, cholagogue, demulcent, diuretic, expectorant, pectoral, purgative, tonic[4, 238, 240]. It can be used either fresh or dried and is best harvested in October or November, though it can be collected until February[4]. The leaves can also be used but are less active[4].
A tea made from the roots is used in the treatment of pleurisy, hives, sore throats and stomach aches and as a mild laxative for children[222]. It was also considered of value for lung ailments and liver diseases[222]. The poulticed root is applied to inflammations[222].
A tea or syrup of the whole plant is anthelmintic[222].

Other Uses

Ground cover Insecticide Potash.

Plants can be grown as a ground cover in a shady position[188, 200]. They form a spreading carpet and are best spaced about 30cm apart each way[208].
The ash of burnt leaves is rich in carbonate of potash[4].

Cultivation details

Easily grown in most light soils[187]. Prefers a soil of leaf mould and a cool but not too moist clay[1]. Prefers a cool damp shady position[1]. Thrives in dry shade[28, 188]. Established plants are drought tolerant[208]. They grow well on drystone walls[200].
Plants often grow as epiphytes[28, 31].
Members of this genus are rarely if ever troubled by browsing deer[233].
A rather variable plant, it is considered to be an aggregate species of several very similar species[187].
Only the roots should be planted, the rhizome being fixed to the surface of the soil[1, 187].

Propagation

Spores - best sown as soon as they are ripe, though they can also be sown in the spring. Sow them on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Pot on small clumps of plantlets as soon as they are large enough to handle and keep humid until they are well established. Do not plant outside until the ferns are at least 2 years old and then only in a very well sheltered position.
Division. This is best done in the spring but it succeeds at most times of the year[1].

Cultivars

''
There are some named forms for this species, but these have been developed for their ornamental value and not for their other uses. Unless you particularly require the special characteristics of any of these cultivars, we would generally recommend that you grow the natural species for its useful properties. We have, therefore, not listed the cultivars in this database[K].
