Horsetail is an herbal remedy that dates back to ancient Roman and Greek times. It was used traditionally to stop bleeding, heal ulcers and wounds, and treat tuberculosis and kidney problems. The name Equisetum is derived from the Latin roots equus, meaning "horse," and seta, meaning "bristle."
Horsetail contains silicon, which can help strengthen bone. For that reason, some practitioners recommend horsetail as a treatment for osteoporosis. It is also used as a diuretic, and as an ingredient in some cosmetics.
