The plant spreads quickly by rhizomes which grow out to 3 feet. Grows wild in northern Europe, North and Central American and other temperate climate places. Medicinally, Horsetail has properties which have been used to treat wounds, enhance skin, hair, and bone health. The plant contains many beneficial compounds with health-promoting effects. Some of the beneficial compounds are antioxidants and silica. The antioxidants protect the body from effects of free radicals that cause cell damage. Silica and oxygen is believed to be beneficial for the skin, nails, hair, and bones.
