2. Feverfew
Feverfew has been used for hundreds of years to treat headaches, especially bad ones. A British placebo-controlled study published in the Lancet found that one capsule of powdered freeze-dried feverfew daily eliminated the symptoms of migraine headaches in 24 percent of patients and reduced the symptoms in other patients. In another study, 70 percent of the patients taking feverfew reported the herb reduced the number and intensity of their headaches.
