The issue many people have is not the fact that complimentary treatments may/may not work - its the poor gullible punters paying the cash that believe modern medicine is hogwash. They need an alternative because medicine has somehow failed them (more likely its our poor NHS that has failed them).

Some people that believe in mumbo jumbo practice dont have any faith in modern medicine - Oh the irony of it, as you need faith in mumbo jumbo to help it work.
