You know what's funny that your post reminded me of, is that in cases of healing or the need for alternative medicine because the other stuff just isn't working, a lot of these people who believe magic is "wrong" abandon that belief to better their health or situation.
I'm a Reiki 2 healer... My teacher worked my fanny off for both of my certifications. When I was finally able to go out on my own, after months of working for hours a day, I started to combine Reiki with Gemstone Therapy. Decidedly different, alternative medicine. You would not BELIEVE the number of people who start off by saying "I don't believe in this stuff, but..." I've built a steady client base on people who "don't believe in this stuff."
When it comes to healing and nothing else is working, people are willing to push their boundaries, go to extremes a little, and branch out.
