Chemical Composition and Nutritional Profile

Field Horsetail contains a variety of bioactive compounds, including silicic acid, alkaloids, flavonoids, and phenolic compounds, which contribute to its medicinal properties.

It is rich in minerals such as silica, potassium, calcium, magnesium, and iron, as well as vitamins like vitamin C and B-complex vitamins. The plant also contains essential oils and terpenes that may support anti-inflammatory and antioxidant effects. Silicic acid is believed to enhance connective tissue strength and improve joint health, while flavonoids and phenolic compounds act as antioxidants, neutralizing free radicals in the body.

Medicinal Properties and Health Benefits

Equisetum arvense has been traditionally used for its diuretic, antiseptic, and astringent properties, making it beneficial for the urinary and respiratory systems by helping to reduce inflammation and support kidney function.

It is also known to aid in the treatment of skin conditions due to its ability to promote healing and reduce irritation.

Forms, Preparation and Usage

Equisetum arvense has been traditionally used in herbal medicine for its purported health benefits, and it is available in various forms including fresh plant, dried tincture, powder, essential oil, and capsule.

To prepare equisetum arvense, it can be made into a tea by steeping the dried plant in hot water, or a decoction can be made by boiling the plant material for a longer period.

The recommended dosage for adults is typically 1-2 grams of dried plant per day, while children should only use it under medical supervision if deemed safe.

Due to its potent nature, it is advised to use equisetum arvense sparingly, with a short duration of use to minimize potential side effects.

Safety, Side Effects and Contraindications

Equisetum arvense can be used in traditional medicine for its purported diuretic and anti-inflammatory properties, but its safety profile requires careful consideration.

While generally considered safe when used in moderate amounts for short periods, it may cause gastrointestinal upset, nausea, or allergic reactions in some individuals. It is important to note that equisetum arvense may interact with medications such as diuretics, blood thinners, and diabetes drugs, potentially enhancing their effects or causing adverse reactions. Special populations, including pregnant or breastfeeding women, should avoid its use due to limited safety data and potential risks to fetal or infant development. Individuals with chronic illnesses, such as kidney or liver disease, should consult a healthcare provider before use, as the plant may exacerbate existing conditions.

To ensure safe use, always consult a qualified healthcare professional, start with low doses, and discontinue use if any adverse effects occur.

Growing, Harvesting and Storage

Equisetum arvense grows in moist, well-drained soils that are rich in organic matter, typically in full sun to partial shade, and thrives in temperate climates with consistent moisture.

It prefers a slightly acidic to neutral pH and benefits from regular watering, especially during dry periods, while avoiding waterlogged conditions. To maintain healthy growth, regular weeding and pruning of the shoots are recommended, and the plant should be kept free from pests and diseases through proper spacing and soil aeration. Harvesting is best done in early spring when the shoots are young and tender, using a sharp knife to cut them just above the soil line to encourage regrowth.

For storage, the harvested shoots should be dried in a cool, shaded area or in a dehydrator, then stored in airtight containers in a cool, dark place to preserve their potency and medicinal properties.
