Horsetail Aerial Extract
Also known as: Equisetum arvense, common horsetail, field horsetail, horsetail extract, Horsetail
Overview
Horsetail (*Equisetum arvense*) is a perennial herbaceous plant from the Equisetaceae family, known for its high silica content, along with flavonoids and phenolic compounds. Traditionally used in folk medicine, it is available in various forms, including capsules, teas, and topical applications. Horsetail is recognized for its diuretic properties and its potential to support bone, skin, hair, and nail health. Despite some clinical evidence supporting its benefits, significant gaps remain in high-quality research, highlighting the need for further investigation into its efficacy and safety.
Benefits
Research indicates several benefits associated with horsetail. A randomized trial with 36 participants demonstrated that 900 mg/day of horsetail extract produced a diuretic effect comparable to hydrochlorothiazide, without adverse organ function effects. Additionally, horsetail may improve bone density when combined with calcium in postmenopausal women. Evidence also suggests its effectiveness in wound healing when applied topically in postpartum women. However, while there are common claims regarding its benefits for hair and nail health, more robust evidence is necessary to confirm these effects.
How it works
Horsetail's diuretic effects stem from its high concentrations of flavonoids, phenolic compounds, and mineral salts, which enhance urine output. Its antioxidant and anti-inflammatory properties arise from these phenolic compounds, which inhibit oxidative stress and inflammation. The plant primarily interacts with the urinary and integumentary systems, promoting better function and contributing to overall health.
Side effects
While horsetail is generally considered safe for short-term use, prolonged consumption is not advised. Commonly noted adverse effects are not extensively documented, although it has the potential to reduce thiamin and potassium levels. Individuals taking medications affecting potassium or thiamin should approach horsetail with caution. It is contraindicated in pregnant and breastfeeding women, and those with heart or kidney disorders, diabetes, or children due to its nicotine content. Individuals susceptible to low potassium should avoid horsetail, and regular health monitoring is advised due to these risks.
Dosage
The effective dosage of horsetail can vary, with a study indicating that 900 mg/day of the extract was effective as a diuretic. Typical doses include 900 mg/day for capsules, 2-3 teaspoons of herbal infusion taken three times daily, and tinctures as directed by a healthcare provider. It is important to maintain adequate fluid intake while consuming horsetail orally. Maximum safe dosage is not firmly established, and prolonged use is generally not recommended due to potential adverse effects. Standardized extracts are preferred to ensure effectiveness.
