Feverfew....it's a pretty wee plant and if you prune the flower heads just as they turn dry then you won't get the seeding issues.
The leaves are bitter, but, and it's a big but, and a good one; see when you have the headache from hell ? or migraine? eat a couple of the leaves.
I find I can't eat with migraine but if I manage to get a couple of the leaves down, it starts to help. With a headache, just butter a slice of bread and put the leaves on the piece and eat that.
It's part of the herbal mix, the synergy, that is used to ease the symptoms of arthritis (including R.A.) and it eases the swelling of insect bites too.
Not suitable for pregnant women, nursing mothers and I wouldn't give it to a pre-school aged child.
It's one of those plants that I'm happy to let seed itself around the flower beds. It's easy enough to weed out when it comes up where I'd rather it not be. It's effective use in settling a misery makes it worth the effort
