Horsetail (Equisetum Arvense), also refered to as Shavegrass, is a perennial related to the fern. The hollow, jointed stems of Horsetail contain large amounts of silica and silicic acids (5-8%). Silica is rich in Calcium and is used by the body in the production and repair of connective tissues and accelerates the healing of broken bones. Silica is also used to maintain and repair the nails, hair, skin, eyes and cell walls.Horsetail is also used for its diuretic and astringent properties, making it a useful treatment for cystitis, bladder and prostate problems, and kidney stones. Horsetail has also been shown to possess hemolytic (blood clotting) and antibiotic activity, properties that contribute to the healing process.Horsetail (silica) reduces the risk of excessive bleeding and contributes to the building of healthy blood cells. Research has shown that Horsetail increases the number of phagocytes (enzymes that kill germs and other foreign substances), which improves the functioning of the entire immune system.
