Horsetail: What Is It?

Horsetail (Equisetum arvense) is a perennial herbaceous plant belonging to the Equisetaceae family, found worldwide except in Australia and New Zealand. Also known by common names such as horsetail or scouring rush, this plant has a long history of use in traditional medicine. The scientific name "Equisetum" comes from the Latin "equi saeta," meaning "horsehair," referring to the appearance of its sterile stems, which resemble a horse's tail.

Horsetail is composed of various beneficial substances, including minerals, vitamins, flavonoids, tannins, and saponins, which give it multiple properties, including diuretic, remineralizing, and purifying properties.

The parts of the plant used are mainly the sterile stems, which are dried to create teas, extracts, or supplements. The use of horsetail extends from the treatment of urinary and kidney disorders to the care of osteoarticular problems and the support of nail and hair health.

Plant

Horsetail is a perennial herbaceous plant that grows spontaneously in moist environments such as ditches, rivers, and streams, mainly in northern Italy. This ancient plant, considered a "living fossil," belongs to the genus Equisetum, the only existing genus of the Equisetaceae family. Horsetails dominated the undergrowth in the late Paleozoic era, and some extinct specimens reached up to 30 meters in height.

The horsetail plant features green sterile stems, about 50 cm tall, characterized by ridges and whorled branches. These stems resemble a horse's tail, hence the common name "horsetail."

Reproduction occurs through spores, spread by a second type of fertile stem, about 20 cm tall and gray in color, which appears at the base of the plant in spring.

Horsetail is a very ancient plant, with fossil remains indicating its presence as early as the late Devonian period, about 395-345 million years ago. It is a more primitive plant than angiosperms, lacking distinct sexual organs and reproducing via spores instead of seeds.

Chemical Constituents

Horsetail is rich in valuable chemical constituents that contribute to its multiple beneficial properties. Among the main components are:

  • Silica: Horsetail is one of the plants richest in silica, an essential mineral for the health of bones, cartilage, skin, hair, and nails.
  • Flavonoids: Especially isoquercetin, known for its antioxidant and anti-inflammatory properties.
  • Tannins: Polyphenolic compounds with astringent and antimicrobial effects.
  • Saponins: Substances that promote the elimination of toxins and the functionality of the lymphatic system.
  • Organic acids: Including ascorbic acid (vitamin C), caffeic acid, and ferulic acid, which have antioxidant effects.
  • Phytosterols: Plant compounds that help regulate blood cholesterol levels.
  • Mineral salts: Horsetail is a source of potassium, calcium, magnesium, and zinc, important minerals for various bodily functions.
  • Vitamins: Including vitamin C and B vitamins.
  • Traces of alkaloids: Nitrogenous compounds with potential physiological effects.

This combination of chemical constituents gives horsetail its properties. Let's explore them together.
