Nettle, so often snubbed as merely a weed, has an amazing array of
talents. It can clothe you, feed you, light your lamps, and be
medicinal!
In
Africa, the oil expressed from nettle seed is used as burning oil in
lamps; and since ancient times it has been made into twine or
cloth. When woven into fine cloth for clothes it is both softer and
warmer than cotton, and was used as a cotton alternative during the
World Wars. In recent years an Italian fashion house produced a
range of jeans made from nettle.
Nettle is perhaps best known as a
highly nutritious feed herb/fodder for animals, and has been used
through the ages for this purpose, occasionally even cultivated en masse and mown to provide ‘hay’ for milk cows. It is
considered a spring tonic and detoxifier for human and animal
alike. It is rich in chlorophyll, and is an excellent source of
calcium,
chromium, magnesium, zinc, cobalt, manganese, phosphorous,
potassium, protein, riboflavin, selenium, silicon, thiamine, vitamin
A, vitamin C and vitamin K. No wonder then that nettle is such an
appetiser, and conditioning, restorative tonic for horses. It is
reputed to enhance coat shine and dappling, and, interestingly, is a
folk remedy for hair loss (perhaps based on its reputation for
enhancing circulation).
Nettle is diuretic (increases urine production) and has been helpful
in eliminating uric acid from the body and thereby relieving the
symptoms of gout. It is also approved for treating and preventing
kidney stones.
Nettle has been shown to have a number of anti-inflammatory
constituents which act via more than one pathway in the body. This
anti-inflammatory activity, hand-in-hand with nettle’s ability to
reduce bleeding, has been applied to easing gastro-intestinal
troubles, including inflammatory bowel disease.
Sufferers of arthritis (both osteo- and rheumatoid) have received
significant benefit from using nettle. It can be taken internally
or applied externally – studies of both methods have shown relief of
symptoms. Amazing results have also been seen when nettle is used
as an adjunct to standard drug anti-inflammatory treatment. In one
study, patients who took a combination of nettle and an
anti-inflammatory drug substantially reduced the dose of the drug
needed for pain relief. Only one quarter of the standard
dose required to provide pain relief was needed when drug treatment
was combined with nettle intake.
Nettle has a centuries old reputation for relieving the symptoms of
nasal and respiratory ailments such as bronchitis, asthma and
allergic rhinitis, as well as skin conditions such as eczema.
Research across the world has vouched for nettle root’s contribution
to treating the discomforting symptoms of benign prostate
hypertrophy (prostate enlargement). On its own, or in combination
with other herbs, nettle root improves Prostate Symptom Scores, and
in one study nettle root combined with the herb saw palmetto was
equally as effective as drug treatment, with the herb extract
treatment tolerated much better by patients due to less side
effects.
Nettle is sometimes used (with other herbs) in the treatment of
laminitic horses, usually on the basis of its stimulation of
circulation and promotion of toxin elimination. Extra support for
its use in treating/preventing this ailment may also come from
animal studies that have indicated a hypoglycaemic effect of nettle
– animals treated with a nettle leaf extract had decreased blood
sugar levels due to an increased production of insulin.
If
you want to harvest your own nettles for you or your animals, be
sure to arm yourself with sturdy gloves and secateurs, and ensure
you are selecting the correct nettle species. To prevent the
nettles stinging when they’re eaten the leaves must be allowed to
wilt before being fed. Additional caution can be taken by allowing
them to dry and then cutting them before feeding them. For humans
they can be cooked as spinach would; and while a cup of nettle tea
may do your body a world of good, your tongue will almost certainly
prefer a softening of the “mown grass” taste of nettle tea by the
addition of a little honey. Your horse will likely relish
the grassy taste!
An
interesting note: It may seem counter-intuitive, but if you are
stung by nettles it is the plant itself that supplies the remedy…
the juice from the plant, when applied to the sting, will relieve
it.
ACTIONS include: Leaf - diuretic (increasing the flow of urine),
nutritive, anti-allergic, astringent (constricts and firms
membranes), styptic (stops blood flow when applied externally),
galactogogue (promoting the production and flow of breast milk),
hypoglycaemic, anti-diarrhoeal, anti-inflammatory, alterative
(“blood cleansing”), stimulating to circulation, tonic.
Root – inhibits/reduces the symptoms associated with benign prostate
enlargement.
CAUTION: Very occasionally a person or animal may develop a rash in
response to ingesting nettle. If so, discontinue feeding it and
seek the advice of a herbalist. A lower dose may be required for
that individual, or possibly a complete elimination of nettle. Very
occasionally gastro-intestinal symptoms may result from ingesting
nettle root. It is generally considered a very safe herb.
While some authors advise caution on the use of nettle during
pregnancy, others disagree and do not expect adverse effects.
DOSAGE: Recommendations for an average sized (450kg) horse range
from 15g (approx 1/3 cup) per day to one cup
three times a day. “The European Medicines Agency saw fit to
establish no maximum intake on nettle herb for animals”1
and there is no restriction on long term use.
DRUG INTERACTIONS: Due to a lack of hard evidence, the potential
for nettle to interact with drugs is largely speculative, based on
the known actions of nettle. Some caution may be required if
combining nettle with anti-hypertensives, anticoagulants, Central
Nervous System depressants, diuretics, insulin, and oral
hypoglycaemic agents. Nettle root may have additive effects on
prescribed medication for BPH, but this may be beneficial. As
mentioned previously, arthritis sufferers were able to reduce drug
dose whilst taking nettle.
