BRACKEN (FERN) PTERIS AQUILINA (LINN)
Bracken is probably the most common fern in Britain and ranges through most of the world, although it is not found in countries around either Pole. It was named by Carl Linnaeus, who believed that the markings when the base of the stem is cut obliquely resembled an eagle, so it was called aquilina whereas pteris comes from pteron or feather in Greek a clear reference to the feathery leaves of the fronds. Bracken must be a prehistoric fern, and although it normally grows to a height of around three feet, it can grow up to 10 feet tall. As a child I would hide from my grandfather when playing hide and seek in the bracken on the mountain, Twm Barlym.

The spores of this fern are invisible to the naked eye, so people wondered how it propagated. It was believed that the seeds of the bracken were visible on St. John’s Eve at the precise moment of his birth only. Shakespeare makes reference to this phenomenon in Henry IV part I , Act II scene 1:

Gadshill…”We have the receipt of fern seed-we walk invisible.”
Here “receipt” means recipe.
Ben Jonson writing later in his play “The New Inn” or “The Light Heart” has this to say:-
“I had no medicine, Sir, to walk invisible,
No fern seed in my pocket.”
Clearly it was a common belief that if you had a fern seed upon your person, you would be invisible in the Renaissance and Jacobean England. Perhaps for this reason it was also thought to convey eternal youth.
Ancient people made diet drinks from the ferns and stems and used it as a remedy for numerous disorders, but as bracken when eaten raw by animals produces cancerous tumours, it is best avoided unless you know exactly what to do with it. It can, if eaten raw also deprive the body of thiamin one of the important B-complex vitamins.

Gerard writing earlier in the 16th century said that the root of bracken “cast into a hogshead of wine keepeth it from souring.”

If you burn bracken the resulting potash is rich in the mineral potassium, and can be used as fertilizer. Dried bracken was once used as thatch and dye can be obtained from it-either green or brown.

A tisane can be made from the roots to relieve stomach cramps, chest pains, internal bleeding, for colds, to get rid of intestinal worms and to stop diarrhoea. Poultices of the root have been used for mastitis, burns and sores. A tincture of the root in wine was used for rheumatism, while glue can also be made from the roots. Some people rub the powdered roots into their scalps to promote hair growth.
However modern medical research does not support these folk ‘remedies’ so bracken is best used as a fertilizer.
