The fact it's allowed to be sold in pharmacies (at least, in my country) is a scary thing.
You find it scary that they sell overpriced water in pharmacies?!?
As you yourself put it, the solution to this "problem" is simple: Read up on what homeopathy is.
By the FDA's own logic: homeopathy is not even drugs, so why the hell do they claim jurisdiction over it? Should they also start regulating witchcraft? how about preach healers? seems like a massive overreach to me for the FDA to start protecting us from water.
