funnily enough I never seem to get headaches even when i'm ill. i'm amused that quackery is sought before medical advice in this thread. I am pleased.

I suggest that there are no homebrew concoctions for headache which is not an illness in itself but a symptom of potentially lots of illnesses ranging from the trivial to life threatening. At the trivial end with something like migrain, this is usually caused by a trigger such as certain foods. the cure for this would not be a concoction to take but a food/chemical to avoid.

At the serious end, no homebrew will save you from imminent death.
