Even Nazarenes believe in anointing with oil and laying on of hands, and they at least used to be an extremely conservative church. It's not at all like the ones you see on televangelists, but I've personally seen healing through both methods...and I've seen it NOT work more often than it did.
As far as alternative medicine...I've seen that too. In the end, I think a lot of it comes from the power of our own minds and faith to heal various afflictions. God created us with a marvelous body and mind, capable of great things. Though, when we take that mind and place it over God and seek power beyond him, we begin to step into the realms of witchcraft.
