Historically, Horsetail has been used to stop bleeding, repair broken bones and as an herbal remedy for arthritis. It has also been beneficial in the treatment of dropsy, gravel and kidney infections, including ulceration and ulcers in the urinary passages.
Because horsetail has the ability to increase urine production, (a diuretic) it had gained popularity as an herbal treatment of kidney stones and urinary tract infections as well as prostrate problems.
Horsetail helps stop bleeding of ulcers and controls excessive menstrual bleeding. Topical preparations of horsetail can be used to heal wounds, sprains, fractures and burns. It has been used as an herbal treatment for rheumatic conditions and skin problems such as dandruff.
It has also been used successfully in the treatment of tuberculosis.
Because horstail is rich in silica and silicic acids it could be benefical as a herbal treatment for osteoporosis.
The herb is used for its diuretic effects, that is, it promotes loss of water from the body. This property can be attributed primarily to the presence of flavanoids.
Some studies support that horsetail could be helpful in improving memory and cognitive function.

Side Effects and Possible Interactions of Horsetail

The herb horsetail is not without its side effects. These include electrolyte imbalance, deficiency of thiamine- if used over a long period or if too much alcohol is consumed while on Horsetail supplements, topical application may cause skin problems, it might produce nicotine toxicity like symptoms such as nausea, muscle weakness, fever, abnormal pulse rate. The herbs diuretic effect causes loss of potassium, which in turn might increase digitalis toxicity. If Horsetail is used with Benzodiazepines, Disulfiram, or Metronidazole, it may cause a disulfiram-like reaction. Use of horsetail in conjunction with other medicines, which lead to depletion of potassium such as Corticosteroids, diuretics, and laxative stimulants, increases the risk of Hypokalemia. Excessive use of licorice with horsetail should be avoided as this combination may lead to cardiac toxicity and also loss of potassium.

Those who should keep away from horsetail include expecting or nursing women, people with a weak heart, people prone to thiamine deficiency such as those who consume excessive alcohol and those who are taking potassium wasting diuretic, a cardiac glycoside (Lanoxin), a corticosteroid, or licorice. It must be kept in mind that sometimes the liquid extract contains 25% alcohol and hence shouldn't be used with Disulfiram, Metronidazole, and Benzodiazepines.

Message: For the last 45 years I have taken a couple of horsetail grass capsuls, every 4 hours, with whatever else I may take, (or when I have nothing else to take) whenever I have a urinary infection, sore throat, respiratory congestion, or infected wound. When I am fathful with this practice, the infections are always washed on out of me in about the half the time,and less. (and pain is also lessened.) I learned this from my grand mother, and to use it also for bowel discomfort. My grandmother grew up on a reservation.

Message: Hi,
and thanks for all the infor on Horsetail, I am researching this herb for pain relief as a salve with some other herbs such as solomons' seal.

I am searching for a relief for my husband who is suffering with the pain, and dealing with some heavy medication..there for I thought I would work with a topical instead of the risk of over doing it, if you can help me with any other solutions I would be so grateful. Thanks for your wisdom..
