Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key 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.

Safety, Cautions & Contraindications
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).
Lower urinary tract / prostate symptoms must be medically assessed first to exclude prostate cancer. The evidence is mixed and rests on small, short, methodologically weak trials, so men with moderate or severe BPH should not rely on it instead of proven treatment.
Generally well tolerated, with mild gastrointestinal effects the most common report.

Botanical Description
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.
Evergreen tree (Rosaceae), 10-30 m tall, with dark, fissured, red-brown bark (the source of the common name 'red stinkwood', from its unpleasant smell when cut). Leaves are glossy dark green, leathery, oblong with finely toothed margins. Small white, five-petalled flowers are borne in axillary racemes, followed by small reddish-brown, two-lobed fruit.
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).
Native to montane forests of central and southern Africa (and Madagascar), growing at moderate to high altitude (roughly 900-3400 m). The species is CITES-listed and conservation-threatened owing to over-harvesting of bark for the pharmaceutical trade.
Harvesting
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.
Bark is traditionally stripped from mature trees. Unsustainable stripping - especially removing bark all the way round the trunk - kills the tree and has driven population decline, so sustainable, partial and rotational bark harvesting or cultivated sources are recommended.
Traditional Uses
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]
Prunus africana bark has a traditional use in East and Central African ethnomedicine for urinary complaints, and its extract (marketed as Pygeum) became one of the most widely used European phytotherapy remedies for benign prostatic hyperplasia (BPH) symptoms in the 20th century. Clinical evidence for symptom benefit is moderate but drawn from small, methodologically weak trials.[11]
Preparations
Dosage
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.
Clinical trials have most often used around 100-200 mg/day of standardised lipophilic bark extract, divided into two doses. Educational reference only, not a prescription; any prostate or urinary symptom should be medically assessed first.
