HISTORY OF FERNS Roughly 12,000 species -Pteridophyta. Reproduce via spores, no seeds- no flowers. Some recent authors have used the term monilophytes. Ferns fossil record 360 mill. years – Carboniferous-many current families & species ± 145 mill. years old, early Cretaceous (after flowering plants came to dominate).
Liquidamber orientalis; Epigaea gaultheroides
Word “medicine” generally translates to mean “mystery”. All of nature comes from the Great Mystery, the mystery of life. Who is to say, therefore, that there is not a design beyond everyday comprehension that brings forth certain plants in abundance for the sake of healing? “Everything happens for a reason”.
FERN ETHNOBOTANY Ferns: -grown or gathered for food, -ornamental plants, -remediating contaminated soils, -remove some chemical pollutants from the air, -play role in mythology+medicine + art.
Homeopathic practitioners have found medicinal uses: Oil from roots used to expel parasitic worms in humans. Liquid extract, powder, pill form. Veterinarians offer animals powdered form + honey to treat intestinal parasites.
Black spleenwort Asplenium adiantum- nigrum L. can be used to treat diarrhea and other disorders- scientific name +common name "spleenwort" -from an old belief, based on the doctrine of signatures, that the fern was useful for ailments of the spleen, due to the spleen-shaped sori on the backs of the fronds. "-wort" is an ancient English term that simply means "plant" Maidenhair fern (Adiantum) functions as a remedy for lung problems. France-a cough syrup is made from the maidenhair's fronds and roots called Sirop de Capillaire.
Black spleenwort Asplenium adiantum-nigrum L. Maidenhair fern (Adiantum venustm)
Roots of the royal fern can help cure jaundice during its early stages, promote healing when applied to wounds. Ferns as Food Roots, or rhizomes, of many fern species are eaten as a rich source of carbohydrates. Osmunda regalis
Bracken fern, although carcinogenic, can be used in place of hops (Humulus lupulus) to ferment beer. Japanese eat large quantities of bracken fern-highest incidences of stomach cancer in the world. Bracken Fern-Pteridium aquilinum
Cooked, raw, or used in a beverage, ferns have many culinary purposes. Fragrant woodfern can be dried, made into herbal tea. Crozier, or curled fiddlehead a delicacy-added to salads as raw; boiled in salt water to remove hairs & scales until soft enough to eat. Well-known fiddlehead fern, delicious spring time food, has a both nourishing & cleansing qualit y. Wood Fern: Dryopteris campylopteris
Black spleenwort Asplenium adiantum-nigrum L. fiddleheads Maidenhair fern (Adiantum venustm)
Ferns have fiddleheads expand into delicately divided fronds. Fiddleheads or Fiddlehead greens are the furled fronds of a young fern, harvested for use as a vegetable. Left on the plant, each fiddlehead would unroll into a new frond.
Fiddleheads harvested early in the season before the frond has opened, cut fairly close to the ground. Fiddleheads have antioxidant activity, are a source of omega-3, omega-6 fatty acids, & high in iron + fibre.
Certain varieties have been shown to be carcinogenic. Fiddlehead resembles the curled ornamentation (called a scroll) on the end of a stringed instrument, such as a violin. Also called crozier, after the curved staff used by bishops.
Helping the Environment Ferns useful for soils, minimize soil erosion & promote stabilization & clean environment. Root system -long, thin, horizontal web of rhizomes below the soil's surface- adds stability + moisture to the soil - soft elegance to garden landscape. Asia-farmers use Azolla fern, an aquatic species, as "green" manure to fertilize rice crops.
Azolla -a "super-plant“, draws down tonnes of N/ha/year (0.25 kg/m²/yr)=6 tonnes / acre of C drawdown (1.5 kg/m²/yr). Uses atmospheric N for growth, main limit to growth availability P. C,N,S arbon, as 3 of the key elements of proteins, and P required for DNA, RNA and in energy metabolism. Grows at great speed in favourable conditions – modest warmth and 20 hours of sunlight, both were in evidence at the poles during the early Eocene – and can double its biomass over 2-3 days in such a climate.
Plants form intimate symbiotic associations or "marriages“ (Algae +Fungi=Lichens; N- fixing bacteria-symbiotically inside the root nodules of legumes). Divorce is practically nonexistent - separations result in the death of one or both partners. Relationship may be decidedly one-sided- only one partner actually benefiting.
Most fascinating of all plant marriages is tiny aquatic water fern (Azolla) and a microscopic filamentous blue-green alga or cyanobacterium (Anabaena azollae). Grow together at the surface of quiet streams and ponds throughout tropical and temperate regions of the world. Azolla the "duckweed fern" grows with 1 or more species of duckweeds (Lemnaceae), including Lemna, Spirodela, Wolffia & Wolffiella.
Azolla may produce reddish anthocyanin in the leaves, in contrast with the bright green carpets of duckweed and filamentous green algae in summer. African water fern (Salvinia rotundifolia),( S. auriculata) - mentioned in the Guinness Book of World Records (1985 UK Edition) as “most intransigent weed.” In 11 months covers an area of 199 km 2, can increase to 1002 km 2. Salvinia rotundifolia
Traditional cultivation as a bio-fertilizer for wetland paddy; used for sustainable production of livestock feed. Rich in proteins, essential amino acids, vitamins + minerals; as a food stuff for human consumption. Feeding azolla to dairy cattle, ducks, chickens-increases milk production, weight of broiler chickens & egg production.
Used for over 1000 years in rice paddies as a companion plant-fix N, block light to prevent competition from other plants. Azolla spp. used to control mosquito larvae in rice fields. Thick mat on water surface -more difficult for the larvae to reach the surface to breathe, effectively choking the larvae.
Paleoclimatological Importance: Azolla event Theory Arctic reports Azolla may have had a significant role in reversing an increase in greenhouse effect that occurred 55 mil. years ago caused the region around the N pole to turn into a hot, tropical environment. Massive patches of Azolla growing on freshwater surface of the Arctic Ocean consumed enough CO 2 from the atmosphere for the global greenhouse effect to decline. Formation of Ice sheets in Antarctica and the current "Icehouse period“ started.

Common fern, Pteridium aquilinum (bracken Or Common bracken) forming thick patches in the forest under-story. Sign of imbalance in the ecosystem, as it grows excessively due to deer overbrowse. Hay-scented Ferns ( Dennstaedtia punctilobula) along with invasive plants like Barberry (Berberis most important wild medicinal herbs ) and Japanese Knotweed (Polygonum cuspidatum) can be harvested without concern.
Antibiotic use becoming more rampant & destructive to our health-Barberry spreads with vigor -offering as a replacement of our favorite drugs. Japanese Polygonum sps. seem to spread in areas struggling with high rates of Lyme disease.
There must be a reason why Hay-scented Fern grows in such abundance. There also must be a reason why deer avoid it in favor of other food. Perhaps it has some toxic properties, which would relate to medicinal properties.

Cornus florida proven to prevent the spread of malaria,bark rich in tannin, used as a substitute for quinine).
Use in gynecology, along with rheumatism, blood disorders, fevers, and lung disorders; but stands out as a remedy for children’s ailments. Finds a high percentage of its uses external, internally it is emetic, at least one use of the fronds specifies that small leaves should be used indicates that there is some toxicity.

Thelypteris palustris MARSH FERN Used as a gynecological medicine. Plants that grow in wet, marshy areas tend to have an affinity with the fluid of the bodies, my guess is that Marsh Fern as a medicinal either removes dampness or builds fluids (nourishes yin).
Reproductive system is an aspect of the traditional Chinese concept of the water element (in the 5 element theory), or of the kidneys. Use may really belong to Cinnamon Fern. Medicinal uses of ferns can be categorized into 5 major groups: those used for rheumatism. those used for the lungs. those used for gynecology. those used for the blood. those used for digestion.
