Horsetail (Equisetum arvense) contains high concentrations of silicic acid and phenolic compounds that support connective tissue mineralization. The silicon content provides structural support for bones, hair, and nails through collagen cross-linking mechanisms.
Origin & History
Horsetail (Equisetum arvense) is a perennial vascular plant native to temperate regions worldwide, harvested from its aerial parts. The plant contains exceptionally high mineral content (5-10%), particularly silicic acid/silicates (5-7.7%), along with flavonoids and phenolic acids. Production typically involves ethanol-water mixtures, ethyl acetate, n-butanol, or water extraction methods to isolate these bioactive compounds.
Research Narrative (Provisional)
The research dossier reveals a complete absence of human clinical trials, RCTs, or meta-analyses for Equisetum arvense. The European Medicines Agency (EMA) assessments note experimental data on silicon bioavailability but found no robust clinical evidence supporting therapeutic claims. EFSA has deemed the available data insufficient to substantiate health claims such as bone remineralization.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
{"macronutrients": {"fiber": "Approximately 10% of dry weight"}, "micronutrients": {"silicon": "0.3% water-extractable", "potassium": "Approximately 15 mg/g of dry weight", "calcium": "Approximately 5 mg/g of dry weight", "magnesium": "Approximately 2 mg/g of dry weight"}, "bioactive_compounds": {"phenolic_compounds": "Includes flavonoids such as quercetin and kaempferol", "antioxidants": "Demonstrates DPPH, NO, and lipid peroxidation inhibition in laboratory assays"}, "bioavailability_notes": "Silicon is present in a bioavailable form, contributing to remineralization support. Other minerals are present in moderate concentrations."}
Reported Mechanism (Provisional)
Horsetail's silicic acid enhances collagen synthesis by promoting hydroxylation of proline and lysine residues, strengthening connective tissue matrix. Phenolic compounds including kaempferol and quercetin scavenge free radicals through electron donation, reducing oxidative stress markers. The high potassium content supports cellular osmoregulation and fluid balance.
Clinical Narrative (Provisional)
Clinical evidence for horsetail remains limited, with most benefits supported by traditional use and in-vitro studies. Laboratory assays demonstrate antioxidant activity with DPPH radical scavenging and lipid peroxidation inhibition. Small preliminary studies suggest potential bone density benefits, but larger randomized controlled trials are needed. Current evidence primarily supports traditional remineralization claims rather than proven therapeutic effects.
