Especially thinking of the fact that something having been around for a long time doesn't necessarily mean it's safe or good....
I agree with Hopez - there has to be control; there have been too many instances (especially with chinese herbals) of manufacturers bunging any old ingredient into pills and potions, just to make it work (like huge amounts of steroids :O ). But banning the lot?! Personally, I think it may make the situation even more dangerous, as people will inevitably try to "make up their own" - which means no control whatsoever.
