Horsetail's Use As A Sedative
Other Common Names: At Quyroughi, Atkuyrugu, Bottle-brush,
Chieh Hsu Ts'Ao, Cola De Caballo, Corn Horsetail, Equiseto Menor, Field
Horsetail, Kilkah Asb, Prele, Scouring Rush, Sugina, Thanab Al Khail,
Vara De Oro, Wen Ching, Equisetum arvense
Range: Britain; Canada; China; Germany; Guatemala; Haiti; Iraq; Kurdistan; Mexico; Panama; Spain; Turkey; USA
Habitat: Open fields, arable land, waste places, hedgerows and roadsides, usually on moist soils.
Horsetails have an unusual chemistry compared to most other plants.
They are rich in silica, contain several alkaloids (including nicotine)
and various minerals. Horsetail is very astringent and makes an
excellent clotting agent, staunching wounds, stopping nosebleeds and
reducing the coughing up of blood. It helps speed the repair of damaged
connective tissue, improving its strength and elasticity.
The plant is anodyne, antihaemorrhagic, antiseptic, astringent,
carminative, diaphoretic, diuretic, galactogogue, haemostatic and
vulnerary. The green infertile stems are used, they are most active
when fresh but can also be harvested in late summer and dried for later
use. Sometimes the ashes of the plant are used. The plant is a useful
diuretic when taken internally and is used in the treatment of kidney
and bladder problems, cystitis, urethritis, prostate disease and
internal bleeding, proving especially useful when there is bleeding in
the urinary tract. A decoction applied externally will stop the
bleeding of wounds and promote healing. It is especially effective on
nose bleeds. A decoction of the herb added to a bath benefits
slow-healing sprains and fractures, as well as certain irritable skin
conditions such as eczema.
The plant contains equisetic acid, which is thought to be identical
to aconitic acid. This substance is a potent heart and nerve sedative
that is a dangerous poison when taken in high doses.
This plant contains irritant substances and should only be used for
short periods of time. It is also best only used under the supervision
of a qualified practitioner.
A homeopathic remedy is made from the fresh plant. It is used in the
treatment of cystitis and other complaints of the urinary system.
Some native tribes liked to eat the young vegetative shoots, picked
before they had branched out, and would often collect them in great
quantity then hold a feast to eat them. The leaf sheaths were peeled
off and the stems eaten raw - they were said to be 'nothing but juice'.
Roots - raw. The tuberous growths on the rhizomes are used in the
spring. The black nodules attached to the roots are edible. It takes
considerable effort to collect these nodules so it is normally only
done in times of desperation. However, native peoples would sometimes
raid the underground caches of roots collected by lemmings and other
rodents in order to obtain these nodules.
A further report says that the peeled stems, base of the plant, root
and tubers were eaten raw by the N. American Indians, the report went
on to say that this may be inadvisable.
The stems contain 10% silica and are used for scouring metal and as
a fine sandpaper. They can also be used as a polish for brass, hardwood
etc. The infused stem is an effective fungicide against mildew, mint
rust and blackspot on roses.
Known Hazards: Large quantities of the plant can be toxic.
This is because it contains the enzyme thiaminase, a substance that can
rob the body of the 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. The plant also contains equisetic
acid - see the notes on medicinal uses for more information.
