Asplenium
ruta-muraria, Rue Fern, Rue Spleenwort, Wall Rue etc.
This is another
Spleenwort, with that goes by many names. Spleenworts were so named
because they were traditionally used in herbal medicine for the
health of the spleen. In the British tradition, this one is usually
called Wall Rue. This one is a favorite of mine due to an ancient
King of England, who is also a Catholic Saint…. And my ancestor!
Yes, my gggg (etc) grandfather, King Edward the Confessor, was said
to have the miraculous power of touching the throat of a person
infected with “scrofula”. Wall Rue is also a cure for this
condition, and closely associated with him. Scrofula was called
called “the king’s evil.” Scrofula is a condition involving
swollen and infected glands in the neck. Although, “the king’s
evil” has also been associated with gout. In the middle ages, in
England, if one did not access to the king, Wall Rue would be used to
cure this debilitating condition. Much earlier though, the ancient
Greeks considered it to be a veritable cure-all.
Brother Aloysius
writes of its use in German Folk Medicine:
Wall Rue (Asplenium
ruta-muraria) - Recommended for jaundice, pneumonia, coughing, pain
in the loins, gravel, bladder complaints, asthma, scurvy, lung
disorders and intestinal blockages.
Mrs. Grieve tells
us:
The Wall Rue,
named by some old writers Salvis vitae, also White Maidenhair, is a
small fern, only 2 to 3 inches high, growing in tufts and embedded in
the crevices and joints of walls. It is much the colour of Garden
Rue, its wedge-shaped pinnules being like those of the Rue, and also
its slender stalks of a pale-green colour.
It was considered
good for coughs and ruptures in children. One of its old names,
'Tentwort,' refers to its use as a specific for the cure of rickets,
a disease once known as 'the taint.' It was also used to prevent hair
from falling out.
Culpepper says:
'This is used in
pectoral decoction. The decoction being drunk helps those that are
troubled with coughs, shortness of breath, yellow jaundice, diseases
of the spleen, stoppings of the urine, and helps to break the stone
in the kidneys.... It cleanses the lungs, and by rectifying the blood
causes a good colour to the whole body. The herb boiled in oil of
camomile dissolves knots, allays swellings and drys up moist ulcers.
The lye made thereof is singularly good to cleanse the head from
scurf and from dry and running sores, stays the shedding or falling
of the hair, and causes it to grow thick, fair and well-coloured, for
which purpose boil it in wine, putting some smallage-seed thereto and
afterwards some oil.'
Plants for A Future
states:
The fronds are
astringent, deobstruent, emmenagogue, expectorant and ophthalmic. A
distilled water made from the fronds has proved of benefit in the
treatment of many eye complaints. The plant is also considered to be
useful in the treatment of coughs and ruptures in children. It was at
one time used as a herbal remedy for rickets and its tannin content
renders it suitable for stopping bleeding from small wounds. The
fronds are harvested in late spring and dried for later use.
Although we have
found no reports of toxicity for this species, a number of ferns
contain carcinogens so some caution is advisable. 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.
