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.

Warnings

Allergies to carrots and nicotine: Some people with allergy to carrot might also have allergy to horsetail. Horsetail also contains small amounts of nicotine (field horsetail contains 0.4 parts per million). People with nicotine allergy might have an allergic reaction to horsetail.

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.
