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.
Sea buckthorn berries are among the richest natural sources of vitamin C, along with beta-carotene and other carotenoids.
A distinctive fatty-acid profile, particularly rich in palmitoleic acid (omega-7), the basis of the oil's skin- and mucous-membrane-healing reputation.
Antioxidant flavonoids contributing to the plant's anti-inflammatory activity.

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).
Berries and juice are safe as food. Seed oil is safe topically and orally in moderate amounts. May have mild anticoagulant effects. May lower blood pressure and blood sugar — use caution with medications. Allergic reactions are rare.
Duke (2002) rates sea buckthorn as +++ and notes antioxidant, hepatoprotective, antiulcer, and vulnerary activities at the experimental level (score 1). The berries are exceptionally rich in vitamins C (one of the highest natural sources) and E, carotenoids, flavonoids, and omega-7 fatty acids (palmitoleic acid). Duke recommends sea buckthorn as a 'food farmacy' — consumed as part of the regular diet for its nutritional-medicinal benefits. Its radioprotective properties have been studied, though without strong clinical validation. No significant safety concerns at food doses (Duke, 2002).

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.
Thorny, deciduous shrub or small tree with narrow, silvery-grey, willow-like leaves. The plant is dioecious (separate male and female plants); female plants bear dense clusters of small, bright orange-yellow berries tightly packed along the branches, giving a striking display in autumn.[4]
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).
Grows on coastal dunes, riverbanks and disturbed, nutrient-poor or sandy soils; native across temperate Europe and Asia, tolerant of harsh, exposed conditions and cold climates, notably widespread in the Himalayan and Tibetan plateau region.[4]
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.
Berries are hand-picked (often by cutting whole fruiting branches, given the thorns and fragile fruit) in late summer to autumn once ripe; leaves are picked through the growing season, and seeds are separated from pressed fruit for seed oil.[4]
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]
Sea buckthorn has a long Tibetan, Mongolian and traditional Chinese medicine history as a nutritive and healing tonic for respiratory, digestive and skin complaints, and the berries are exceptionally rich in vitamin C and carotenoids; the oil, from both fruit and seed, has a particular traditional and modern reputation for soothing and healing irritated or damaged skin and mucous membranes.[1, 4]
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.
