just to put this down, clearly.

what do i think about "herbal medicine"?

well, what does the science say? herbal medicine that works is called medicine. herbal medicine that doesn't work is called a placebo. and, herbal medicine that hasn't been tested is unknown.

so, i don't want to make broad comments about it; if people have been using some root for some reason for centuries, there may very well be good reasons for it. fine. but, show me the study.

and, that's really the right answer.

show me the study!

sure, it might work - i won't write it off, a priori. there's no reason to. but,

show me the study!
