Key Constituents
Responsible for the characteristic astringency.
Antioxidant and anti-inflammatory constituents.
Field horsetail is exceptionally rich in silica, concentrated in the stem, and is a signature source of this mineral in Western herbal medicine.
Antioxidant flavonoids contributing to the plant's anti-inflammatory activity.
An enzyme that degrades vitamin B1 (thiamine); the basis of the caution against prolonged or excessive use.
Pharmacological Actions
Anti-inflammatory gargle (mild inflammation of the mouth and throat / sore throat)
Agrimonia eupatoria ethanolic extract is cytotoxic to breast, colon, lung and cervical cancer cells and inhibits the PI3K/Akt/mTOR pathway (preclinical/in silico).
Traditional & Indicated Uses
inferred from bitter-tonic action
inferred from anti-inflammatory action
Agrimonia eupatoria ethanolic extract shows dose-dependent cytotoxicity against MCF-7 (breast), HT-29 (colon), A549 (lung) and HeLa (cervical) cancer cells and inhibits the PI3K/Akt/mTOR/COX-2/MMP-2 axis (preclinical).
Astringent (relief of mild diarrhoea)
Mild bitter digestive tonic (indigestion)
Anti-inflammatory gargle (mild inflammation of the mouth and throat / sore throat); Vulnerary (minor skin inflammation and small superficial wounds, topical)

Safety, Cautions & Contraindications
Traditional-use indication only: if diarrhoea persists longer than 3-4 days, or symptoms of mouth/throat inflammation persist beyond about a week, a doctor should be consulted.
Use during pregnancy and breastfeeding is not recommended, as safety has not been established.
Field horsetail contains thiaminase, an enzyme that degrades thiamine (vitamin B1); prolonged or excessive use can cause thiamine deficiency — symptoms include neurological problems and weight loss. This risk is greatest with repeated large doses or prolonged use. The plant also contains nicotine at low levels and silica compounds. Not recommended for children or during pregnancy and breastfeeding. People with impaired kidney function should avoid use, as diuretic effects may worsen fluid and electrolyte imbalance. Caution with concurrent diuretic medications. The EMA herbal monograph recognises traditional use at appropriate short-term doses in adults only (European Medicines Agency, 2016; Sandhu et al., 2010).
Duke (2002) rates horsetail as + (moderate caution) and notes clinical evidence (score 2) for its diuretic and wound-healing (vulnerary) activities, consistent with Commission E approval. High silica content may strengthen connective tissue, hair, and nails. Dose: 6 g dried herb daily as tea or in capsules. Horsetail contains thiaminase (breaks down vitamin B1) and an unidentified neurotoxin — it should not be taken long-term or in large quantities. Not for use in patients with edema due to cardiac or renal insufficiency, and avoid in children under 12 (Duke, 2002).

Botanical Description
Slender, downy perennial herb with a basal rosette of pinnately compound leaves and a single, unbranched, upright flowering stem. The leaflets are toothed, alternating large and small, and silvery-downy beneath. Small, five-petalled, bright yellow flowers are borne closely along a slender terminal spike (raceme), opening a few at a time from the base upwards, giving the old name 'church steeples'. After flowering, small bristly, hooked burrs form that cling to clothing and animal fur for dispersal.[13, 14]
Perennial, spore-bearing (non-flowering) plant with two distinct stem types arising from a deep, black, jointed rhizome. In early spring, unbranched, pale brownish fertile stems appear first, each topped with a spore-bearing cone, and die back once spores are shed; these are followed by the familiar green, hollow, jointed, ridged sterile stems bearing whorls of thin, needle-like branches at each node, giving a bottlebrush appearance.
Habitat
Grows in damp grassland, waste ground, riverbanks, roadsides and disturbed soil on a wide range of soils; native and common across the temperate Northern Hemisphere (Europe, Asia, North America).
Harvesting
The flowering aerial parts are cut in summer, at the start of flowering, and dried promptly in a warm, airy, shaded place.[13]
The green sterile stems are cut in summer, at their most vigorous, and dried quickly in a warm, shaded, airy place; careful identification against the more toxic marsh horsetail (Equisetum palustre), which grows in similar damp ground, is essential before wild-harvesting.
Traditional Uses
Agrimony has a long folk history as an astringent remedy for mild diarrhoea, as a gargle for sore throats and mild mouth/throat inflammation, and as a mild bitter digestive tonic; it has also been applied topically to minor wounds and skin inflammation. It is officially recognised in the European Union herbal monograph for traditional use in mild diarrhoea and mild inflammation of the mouth or throat.[13, 14]
Field horsetail has a long European folk history as a diuretic remedy for urinary gravel and mild fluid retention, as an astringent, anti-inflammatory and vulnerary herb for wounds and connective-tissue support, and, owing to its very high silica content, as a traditional tonic for hair, nails and skin.[11]
Preparations
Dried sterile stem simmered or infused in hot water as a traditional diuretic and connective-tissue-support tea.
Dosage
The EU herbal monograph gives 1.5-4 g of the comminuted herb in 250 mL (or less) of boiling water as an infusion, 2-3 times daily, in adolescents, adults and elderly. As a gargle for mild oral or throat inflammation, 1.5 g in 150 mL of boiling water 2-4 times daily, or a decoction of 3-4.5 g in 250 mL 2-3 times daily. Educational reference only, not a prescription.
The EU herbal monograph gives 1-4 mL three times daily (orally, or as a gargle for oral and throat use). Educational reference only, not a prescription.
The EU herbal monograph gives a single dose of 1-4 g of the comminuted herb in 150 mL of boiling water as an infusion or decoction (5-15 minutes), 3-4 times daily, for a daily dose of 3-12 g, in adolescents, adults and elderly; traditionally used over a period of 2 to 4 weeks. For cutaneous use, 10 g in 1 L of water as a decoction for impregnated dressings and irrigation. Not recommended under 12 years. Educational reference only, not a prescription.
