Faith/Holistic healing and Psychics are two of my biggest pet hates and I've spent a fair amount of time reading about/researching both, so let me save you a bit of money.
On the subject of 'alternative medicine', scientists have worked for hundreds of years to finds cures and treatments for every ailment known to man (they haven't found every cure but they've done a lot more than Holistic Medicine). These are treatments that although not 100% effective in every case, are rigorously tested to ensure they have basis in scientific fact and logic.
Holistic/alternative medicine is a mixture of guess work, spiritual pseudo-science and pure fiction which is propagated entirely by the 'placebo' effect and sheer desperation. If you have a genuine ailment, be it physical or psychological, see a GP.
On the subject of psychics, there is not a single shred of evidence to support anything they do. Ask yourself one question when you watch a psychic...'why do they say things like
'I'm getting name starting with B' or
'Is there something to do with your dead uncle and a hat' instead of giving a full name and address. Why on Earth would the dead be trying to trick the living with cryptic clues? It's all done through a combination of cold reading and linguistic trickery. If you want a Psychic reading, I'll do it for you and charge you half the price of whoever you plan on going to will and I'll probably get a fair amount right through pure guess work.
Watch anything by Derren Brown as an example, he does exactly what 'psychics' do yet openly explains it's done by nothing more than trickery and psychology.
If you need further convincing watch these documentaries by Richard Dawkins, the first dealing with psychics etc, the second with alternative medicine.

On the subject of hypnosis, it's a very different thing. Hypnosis is undoubtedly real but it can only be used for a number of very specific issues, so it would depend entirely on what problem you have.
