3. Indications and Uses

White willow contains the same salicylates used in aspirin, but in a less concentrated form. Although aspirin works faster, white willow may be a better choice for those who get stomachaches from aspirin or who are treating chronic pain conditions, such as rheumatoid arthritis.

Low dose aspirin are now recommended to prevent heart attack. Aspirin thins the blood, which can help prevent blood clots that cause heart attack and stroke. Drinking willow bark tea may have the same effect, without increasing the risk of stomach bleeding and ulcers. White willow can also suppress inflammation and uterine cramping caused by prostaglandins.

Like aspirin, white wilow may help reduce the risk of stomach and colon cancer. In one study it was also shown to help reduce blood sugar.

4. Safety Concerns

Do not give white willow to children to treat fever resulting from cold, flu, or chickenpox -- it is not known if white willow, like aspirin, could cause potentially fatal Reye syndrome in children with these illnesses. People with ulcers or gastrointestinal conditions should not use white willow without first consulting their doctor-white willow may aggravate symptoms or cause stomach upset in some sensitive individuals. Those taking blood thinners should avoid this herb also, as it may increase the action of these medications.

5. Dosage Information

White willow is available in bulk powder or capsule form. It is also available in commercial tinctures and extracts. Make sure to follow dosage instructions on commercial preparations. To make white willow tea at home, use 1 teaspoon of powdered bark per cup of hot water, and drink up to 3 cups a day. White willow tastes bitter, but it's okay to add sugar or honey.
