Horsetail is a plant rich in mineral salts (silicon, potassium, phosphorus, magnesium, calcium, etc.) and flavonoids. It has diuretic (helps to reduce fluid retention), remineralising, anti-inflammatory and antioxidant properties.
It is also used in skin care because it promotes elasticity and collagen maintenance, as silicon can strengthen the structure of connective tissue. It is often used in strengthening treatments for nails and hair. If you are taking medication or have a condition, consulting a healthcare professional before considering a horsetail supplement is recommended.
