i think some naturopaths are more "spiritual" than others. If its not something you are comfortable with just make sure you research them before. Most are based on Science or years of research into natural medicine.

I have used Naturopaths and Traditional Chinese Medicine and i found better results with the TCM. My MIL on the other hand loves her naturopath and has seen great results.

I would research a Naturopath or TCM that has experience in the areas you want help with. I know a friend of mine had great success with getting help for her depression via natural means, but the healthcare provider she went to had a special interest in that area and quite a bit of success.
