MEDICINAL USE OF FEVERFEW

Herbalists use feverfew for migraines, in particular migraines caused by hormonal imbalances. The reason it works so well for migraines is the presence parthenolide, a compound that inhibits histamine as well as serotonin (which is thought to trigger migraine). This lowers inflammation, pain and the frequency and severity of migraines as well as their associated symptoms (nausea, vomiting, sensitivity to light, etc).
Feverfew inhibits the formation of platelets causing an improvement in blood flow. It also inhibits the production of prostaglandins which leads to reduced inflammation and pain.
