If you get migraines, consider trying butterbur extract. This recommendation comes from the American Academy of Neurology and the American Headache Society, based on a review of studies from the past decade.
Of all alternative therapies evaluated, the herb butterbur (Petasites hybridus) was the only one “established as effective” in reducing the frequency and severity of migraines. The herb feverfew (specifically an extract called MIG-99), magnesium and riboflavin were rated as “probably effective.”
But the evidence for omega-3s and other herbal or nutrient supplements was inadequate or conflicting. Look for purified butterbur extracts that have no detectable levels of alkaloids—the German-made Petadolex is considered safe. Don’t use butterbur if you are pregnant, nursing or are allergic to plants in the daisy family.
