A cousin of the fern, Horsetail (Equisetum arvense) is a flowerless plant that contains 5-8% silica and silicon acids. The body uses silica in the production and repair of connective tissue and helps accelerate the healing of broken bones. Silica is also necessary to maintain and repair the nails, hair, skin, eyes and cell walls. It's a common ingredient in hair and skin care products and nutritional supplements. Silica is more abundant in our tissues when we are younger, but declines with age.
Horsetail is available as a dried herb, often prepared in capsule or infusion form, as well as a liquid extract and tincture. It requires storage in sealed containers away from sunlight and heat. Horsetail contains traces of nicotine and is not recommended for young children. In addition to the Equistetum arvense type of Horsetail, there is another species called Equisetum palustre that is poisonous to horses. To be safe, you should never take that form of horsetail.
There there are many other medicinal uses for horsetail -- each with unique dosing based on the condition being treated and other individual variables. To ensure the potency and quality of the herb for your health needs, talk with your holistic health practitioner.
