Equisetum arvense is the Latin botanical name for Shavegrass Herb. It is often commonly referred to as horsetail, bottle brush, equisetum or scouring rush. Shavegrass Herb contains silica, calcium and potassium. Equisetum arvense should not be used if you have renal or cardiac dysfunction.
Horsetail is used for "fluid retention" (edema), kidney and bladder stones, urinary tract infections, the inability to control urination (incontinence), and general disturbances of the kidney and bladder. Horsetail can be applied directly to the skin to treat wounds and burns.

Diabetes: Horsetail might lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use horsetail.
Low potassium levels (hypokalemia): There is some concern that horsetail might flush potassium out of the body, possibly leading to potassium levels that are too low. Until more is known, use horsetail with caution if you are at risk for potassium deficiency.
Low thiamine levels (thiamine deficiency): Taking horsetail might make thiamine deficiency worse.
