Any massage therapist who says that you will receive any other benefit besides feeling nice or loosening up a muscle is pulling your leg.
Any chiropractor who says they can do anything besides make your joints and tendons make a popping sound and MAYBE providing temporary relief from something that needs surgery or professional evaluation is pulling your leg.
There's a reason that naturopaths aren't allowed to diagnose or treat with real medicine: it's because their entire philosophy is to create a magic sugar pill to convince you, and sometimes their self, that something really is happening.
The only skill any new age or holistic healer has is to make a hubbub.
It depends upon the naturopath and what kind of training. I don't want to start a debate on naturopathy, but there are some who base their practice in science and not in New Age philosophy. There are about a dozen states that license NDs who have graduated from pre-med school and ND grad school. Unfortunately, when four-year naturopathic schools like Bastyr have LGATs like LE on campus, there will be graduates who throw out any science they are taught and turn toward LE "technology." It is unfortunate that legitimate massage therapists, NDs, chiropractors, herbalists, etc. have to suffer because of the minority that distort science, physiology and psychology. Not only do clients have to be very careful screening their practitioners, but practitioners have to carefully screen their clients, people who are looking for transformation as opposed to relief from an ailment.
Mainstream psychologists are turning toward this nonsense in droves, as discussed elsewhere on RR.
