Feverfew is excellent as a preventative for recurrent headaches. Research has shown that this is probably due to it having a beneficial effect on the platelet clumping implicated in migraines. It is best taken as a fresh tincture, capsule or mixed with food (I find adding a few leaves to a marmite sandwich also masks the strong flavour) as just chewing the leaves can cause mouth irritation.
The name ‘feverfew’ is less likely to have evolved for an action in lowering feverish temperatures, but more because it eases the aches that often accompany a cold, chill or flu.
Other plants that help with headaches and migraine include scullcap, ginger and cayenne pepper.
