An incredibly ancient lineage of fern. Branched members of the genus are referred to as "candock," and unbranched or sparsely-branched species are referred to as "scouring rush" for their use as an abrasive and superficial resemblance to rushes.
Bark Properties: Rich in silica.
Horsetail has a long history of being used as an abrasive, going back to at least ancient Sumeria. While not as effective an abrasive as modern sandpaper with its clear grades, when balled up, it doesn't get clogged with sanded material the way sandpaper does. It was used in the sanding of wood and the polishing of metals. It was particularly good at polishing tin, hence its German name, zinnkraut ("tin-herb").
We are not a medical blog; do not take health advice from us.
Despite being used medicinally in traditional medicine for millennia, there is little evidence that horsetail has natural medicinal properties.
Supposedly it was used as a stimulant, for weight control, skin and hair health, as well as bone health.
Contains the enzyme thiaminase, which breaks down thiamine (Vitamin B1), which can result in vitamin deficiency, making this herb toxic in large amounts, causing liver damage. Inadvisable as fodder for grazing animals for extended periods, and its effects on pregnant women has not been verified.
History of consumption, with fertile stems boiled like asparagus. Can be eaten cooked or, in the case of young shoots, eaten raw. As noted above, extended consumption is dangerous.
- According to Andy Duling, the high silica content in the skin of horsetail can be used for sanding, but he had difficulty doing so, and was not impressed with the results. In contrast, Cappelle says it's quite useful, but notes that it should be cooked before drying for this purpose. Cappele balls it up, and this assists in preventing sawdust clogging.
- This didn't just sand wood, but was apparently used in the polishing of metal, from kitchen pots to armor, according to a commenter on Cappelle's article.

Europe, Western:

Biome: Arctic and Temperate environments
Herbaceous perennial, with separate sterile and spore-producing stems. The sterile stems are green and photosynthesize, while the fertile stems are non-photosynthetic. Fertile stems grown in early spring, and sterile stems grow after the fertile stems wilted, and persist until autumn frost.
Horsetail rhizomes may penetrate the soil down to 1.8m (6ft) in depth. This species is incredibly difficult to get rid of in part for this reason, even resisting herbicides.
Apparently, this is the least toxic species of horsetail.
Sanding/Polishing
Used especially in the
polishing of pewter, hence the name "pewterwort."
Music
Used to dress the wheels of
hurdy-gurdies to remove resin build up.
Agriculture
Water-based extract of this
plant is approved for use as a fungicide by the EU and post-Brexit UK. Also
reduces the impact of excess moisture on other plants. High silica content
reduces moisture impact.
We are not a medical blog; do not take health advice from us.
Despite being used medicinally in traditional medicine for millennia, there is little to no evidence that horsetail has real medicinal properties. Many of the following ideas come from traditional [Austrian folk medicine].
Supposedly horsetail ferns are:
- Anti-inflammatory
- Antioxidant
- Antifungal (Confirmed)
- Antimicrobial
- Diuretic
In tea or topically in compress and back, it was and is used in the treatment of the following:
- Chilblains
- Gout
- Kidney/UI issues
- Locomotor issues
- Skin disorders
- Rheumatism
- Wounds
Harvesting
For medicine, it is necessary
to harvest the green stalks in spring or early summer while the leaves are
"up." They should be bright green to be good for this purpose. During the
summer it is also possible to harvest the tops. Boiling longer extracts more
silica.
Horsetail absorbs environmental toxins, so be careful where you collect your horsetail. Also mind that it is not marsh horsetail (Equisetum palustre), which is notably more toxic.
Anti-Inflammatory
This plant has many
anti-inflammatory claims, which do not appear to have much scientific
support. Still, assuming the claims are true, reduction in inflammation is
supposed to promote stronger immune response against various pathogens. For
this effect is best taken in tea or powdered supplement.
Bleeding/Wounds
This is a mild styptic,
stopping bleeding. The barren stems and tops should be applied directly to
the wound. Taken orally, this is thought to also treat excessive
menstruation.
Joint Health
Supposedly the silica in the
stalks of this plant is good for the joints and other connective tissue.
Bones
The high silica content in
horsetail is supposed to promote strong bones, and is used to treat
osteoperosis when used consistently.
Teeth
The high silica content in
horsetail is supposed to promote strong teeth. It can be made into a tooth
powder that assists with cavities and enamel repair.
Skin and Hair
The high silica content in
horsetail is supposed to treat skin issues. The silica is supposed to
stimulate production of collagen to reduce the effects of aging by
preventing fine lines and promoting healthy hair. It can be taken
internally, externally as toner or wash, or added to a topical medium such
as a cream, lotion, or salve.
Diuretic
Horsetail is said a gentle
diuretic, which helps rid the body of excess fluids and salts. Treats kidney
and UI issues, and prevents kidney stones from developing. Taken daily
orally and with bath it can treat the symptoms of UTIs.
Antimicrobial
Horsetail is claimed has
anti-inflammatory, antimicrobial, and antifungal properties (only the
antifungal properties are confirmed). For this reason it treats external
infections in warm compress or poultice, and can be used to treat fungal
infections of the foot in a daily soak or to prevent such through soaks on
alternating days.
Respiratory
Inhaling the steam of
horsetail tea is supposed to reduce nasal and bronchial inflammation and
congestion. Supposedly this also strengthens the immune system. Also treats
sore throat in a saltwater gargle when combined with lemon juice.
Cognitive Function
The antioxidants in horsetail
are supposed to prevent neural degeneration, preserving cognitive function.
Apelian and Davis reference anecdotal evidence (their words) that it helped
treat Alzheimer's in some patients.
Diabetes
The claim is that it helps to
balance insulin levels in the body by lowering blood sugar. Apelian and
Davis regard this as a short-term solution only.
While less toxic to humans than other horsetail species, it's still dangerous to livestock as a prolonged source of feed. Apelian and Davis also say beyond thiamine deficiency, it can cause potassium deficiency, lowered blood sugar, and kidney irritation. Not for pregnant women.
Further, it can synthesize nicotine under certain conditions, and overconsumption can lead to nicotine toxicity.
Rich in silicon, potassium, calcium, manganese, magnesium, phosphorus, fiber, Vitamins A, E, and C, and a host of other dietary chemicals. Buds are eaten as a vegetable in Korea and Japan. They are naturally bitter, do not eat raw. Change the water 2-3 times when boiling to reduce bitterness.
Rhizomes are edible, but hard to harvest in sufficient quantities. This makes them a starvation food.
- The horsetail scours resin from hurdy-gurdies. Due to the potential symbolic density of the hurdy-gurdy (sacral origin, divine drone, cyclicality, bridge from sacral to profane, accumulation of gunk, etc.), much can be done with the horsetail in this regard.
- Horsetail could be used in a regenerative capacity relative to the hurdy-gurdy, revitalizing the patient to restored faith or similar state by removing the accumulated malaise of repetition and habituation. Similarly, this could be used to break someone from a persistent hypnotic state.
- The above parallels its use as a sanding material and its supposed antioxidant properties vis-à-vis neurological health. Many of the purported medical benefits could easily be framed relative to the plant's scouring properties, if the characters perception of the world is pre-scientific.

Grows 30-100cm (occasionally 140cm) tall with dark green stems between 2-8mm in diameter. These stems are smooth with fine ridges. It is difficult to tell apart the fertile and photosynthetic stems. Stems pull apart readily at the joints.
Used as an abrasive for scouring, sanding, and filing, as other horsetails.
We are not a medical blog; do not take health advice from us.
Used in the ancient Mediterranean to stop bleeding, treat UI issues, ulcers, and tuberculosis.
The Chinese used it to treat superficial obstructions of the eye.
As generic.
Shoots harvested in the early spring can be eaten, but should not be consumed over extended periods.
According to Linnaeus, a fodder favored by reindeer. Used in Sweden to promote milk production in cows. Horses will not eat it. Waterfowl are known to eat the rootstock.
- Chinese use of the obstructions of the eye could be translated magically as scouring or buffing away obstructions and blindspots. As such, horsetails could be used magically to disabuse people of their biases and ideological blinders (or to push situations that do the same).
