This perennial herbaceous plant is a fern of 20-60
cm length, with a black rhizome. Stems are aerial and erect (20-60
cm long) and articulated with marked nods of brittle and longitudinal
grooved surface. Leaves are microphyll kind (small, with a middle non-branched
nerve), joined together terminating in sheathes, with 6 to 12 black teeth. The
aerial stems are of two kinds: fertile stems (smaller and reddich-brown or
yellow) and barren stems (taller and green).
These are very primitive plants that were related to ferns and there are
around 50 different species known, around the world; most of them in the North
Hemisphere. They have no flowers nor seeds and as ferns are reproduce by
spores. They belong to the Equisateaceae family.
Horsetail grows widely distributed around the mild weather zones of the
north hemisphere in Asia, North America and Europe. It is found in
hedgebanks, non-cultivated soils, sandy, humid and clayey terrain, in streams,
etc. in most parts of the Iberian Peninsula, especially at the northern
part. The barren stems are harvested in spring and summer.
Barren stems, fresh or dried. Fertile stems have no
> Osteomuscular disorders: osteoporosis, fractures,
rheumatism, rachitism, arthritis, arthrosis, etc.
> Genitourinary disorders: cystitis, urethritis, prostatitis, urethritis,
pyelonephritis, renal lithiasis, vulvovaginitis, enuresis.
> Oliguria, edemas, post-traumatic edema and urinary retention.
> Hyperazotemia, hyperuricemia, gout.
> Sportspeople: ligament distention, joints damage, whenever greater
physical effort is required.
> As a helper in treating obesity with liquid retention, weight swinging,
> Lung infections: tuberculosis (these people show low levels of silica)
> Asthenia, fatigue and convalescence.
> Hemorrhage: hematuria (blood present in urine), metrorrhagia
(abnormal uterine bleeding), hypermenorrhea (heavy menstrual flow), hemoptysis
(coughing up of blood from the respiratory tract) intestinal hemorrhages, etc.
> Hyperchromic anemia or by medullary deficiency.
> Arterial hypertension.
> Arteriosclerosis prevention (people suffering from this disease show low
silica levels. Silica helps to fix and use calcium in the body and protects
arteries against fatty deposits).
> Prevention of baldness, dandruff, fragile and brittle fingernails, flabby
skin, prevent and diminish stretch marks, wrinkles, restrain skin aging.
> Gastroduodenal ulcers.
> Hard to heal wounds, eczemas, dermatitis,
erythema, torpid ulcer on the skin, abscesses, varicose ulcers, burns
> Hemorrhages: epistaxis (nose bleeding) nose washes in cold, etc.
> Bleeding hemorrhoids (sitz baths)
> Chillblains, plantar hyperhidrosis
> Oral disorders (gargles and washes): oral ulcerations, parodontopathies,
> Corneal ulcerations, blepharitis, conjunctivitis, stye, swollen or painful
> Inflammation or infection in the vulva and vagina: vulvitis,
> Breast atony or mammary flaccidity (Internal use support).
> Weak and brittle hair, dandruff.
> Light bleeding colitis (enema).
> Horsetail decoctions concentrations can be used to combat plagues from the
orchard, fruit trees, etc. in a very ecological way. It is also used to
eliminate fungi and insects when used along with nettle.
