Horsetail Equisetum Arvense

Horsetail (Equisetum arvense L., Equisetum myriochaetum )has traditionally been used as a diuretic, as an astringent to stop bleeding and stimulate healing of wounds and burns, and as a cosmetic component, as well as for treatment of tuberculosis and of kidney and bladder ailments (eg, urethritis, cystitis with hematuria); however, clinical trials are lacking to support these uses. Clinical data demonstrate a hypoglycemic effect with the use of E. myriochaetum and efficacy in treating brittle nails with the use of E. arvense.
