There are some great benefits for 'alternative' therapies. For example, a massage therapist might relieve tension or soreness in your muscles. It can certianly feel good and relaxing. Thus there is some benefit.

On the other hand, if a massage thearapist says he/she will reallign your energy channels and cure your cancer, then you are being scammed. The medical profession has a legitimate interest in preventing this kind of scam, and educating the public against it.
