Feverfew: In supplement form — as long as it contains at least 0.2 percent parthenolides — 100 to 150 milligrams a day may work in reducing migraines. Feverfew has been shown to be effective in numerous studies for migraine prevention.
Butterbur: A small, 2004 study found that patients who took 75 milligrams of butterbur twice daily had around 50 percent fewer migraines, compared with a 25 percent decrease experienced by people given only a placebo. The chemicals in butterbur are thought to decrease muscle spasms and inflammation in the blood vessels of the brain, which can cause headaches.
Ginger: Ginger can help in two ways — as an anti-inflammatory and as an anti-nausea medication. Fresh ginger appears to work the best; you can try to smell freshly crushed ginger for nausea, or steep some in hot water for a tea. Ginger ale, unfortunately, does not work for migraines.
