I read in Bottom Line Health that Feverfew flower extract works just as well as Gabapentin for neuropathic pain, but it has to be an extract of the flowers only, not the leaves. I am having trouble finding an extract made only from the flowers. Has anybody ever heard of this?

Also read about it here:
