Overview

Overview Information

Horsetail is a plant. The above ground parts are used to make medicine.

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.

It is also used for balding; tuberculosis; jaundice; hepatitis; brittle fingernails; joint diseases; gout; osteoarthritis; weak bones (osteoporosis); high cholesterol levels; frostbite; weight loss; heavy menstrual periods; and uncontrolled bleeding (hemorrhage) of the nose, lung, or stomach.

Horsetail is applied directly to the skin to treat wounds and burns.

Horsetail is sometimes used in cosmetics and shampoos.

How does it work?

The chemicals in horsetail may have antioxidant and anti-inflammatory effects. Horsetail contains chemicals that work like "water pills" (diuretics) and increase urine output.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Weak bones (osteoporosis). Early research suggests that taking dry horsetail extract or a specific product containing horsetail extract and calcium can increase bone density in postmenopausal women with osteoporosis.
  • Fluid retention.
  • Frostbite.
  • Gout.
  • Hair loss.
  • Heavy periods.
  • Incontinence.
  • Kidney and bladder stones.
  • Urinary tract infections.
  • Use on the skin for wound healing.
  • Weight loss.
  • Other conditions.
More evidence is needed to rate the effectiveness of horsetail for these uses.

Side Effects

Side Effects & Safety

Horsetail is POSSIBLY UNSAFE when taken by mouth long-term. It contains a chemical called thiaminase, which breaks down the vitamin thiamine. In theory, this effect could lead to thiamine deficiency. Some products are labeled "thiaminase-free," but there is not enough information available to know if these products are safe.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking horsetail if you are pregnant or breast-feeding. Stay on the safe side and avoid use.

Alcoholism: People who are alcoholics are generally also thiamine deficient. Taking horsetail might make thiamine deficiency worse.

Allergies to carrots and nicotine: Some people with allergy to carrot might also have allergy to horsetail. Horsetail also contains small amounts of nicotine. 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.

Moderate Interaction

Be cautious with this combination

!

  • Lithium interacts with HORSETAIL

    Horsetail might have an effect like a water pill or "diuretic." Taking horsetail might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.

Dosing

Dosing

The appropriate dose of horsetail depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for horsetail. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
