Dr. Steven Horne qoting:
"When it comes to using feverfew for migraines there are several things you need to know.
First of all, it’s not a cure for migraines and it will not relieve the pain of a migraine that’s already started. It’s a palliative for migraines.
Taken regularly feverfew can reduce the frequency and intensity of migraines, but it does not fix any of the root causes of migraines.
In fact, some people who have taken it have found that migraine headaches return and were more severe after it was discontinued.
It also doesn't work on all types of migraines. It works primarily for vasodilative migraines where the pain is pounding or throbbing.
Other indications it might be helpful include indigestion, blood stagnation, and a pale, bluish complexion that becomes red with fever or headache.
Also don’t use feverfew if you are pregnant or trying to become pregnant."
