Hi anne,
Well, I think it's super wise of you to check things out. In my life, coverse to most folks I know, I go the natural route first and then if I have to, see a conventional doc. As others have said, it will depend on the naturopath you choose. And also on what your personal beliefs are. Some do use many new age therapies. Others don't. Some are Christians. Some are not.
For me personally, I'm very careful. I was saved out of the new age and I chose to stay away from all new age practice. My wonderful Christian chiropractor recently put something on my back and said it was a quantum physics stone. I wasn't in very good shape at the time and I wasn't thinking. I later realized it was a crystal. That's over the edge for me, quantum physics or not. I don't know how it is for those who do not have a background in the occult, but I do know for those of us who do, things like that can open the door to the enemy, not for possession, but definitely for harrassment. I'm told there can be the same sort of effect in everyone regardless of background.
I also know that if you continue to seek information and pray for discernment, the Lord will give you an answer. And in His plan there is no trade-off. It's not, "Well, I guess I have to put up with it, because this guy's the best chiropractor around." It's God's grace, "I must not need a chiropractor for now. Great, I get to save some money. Father God, please let me know who and when if I need one again. Thanks."
Meanwhile, Dr. Don Colbert is a great Christian M.D. who's written a ton of books on natural health practices you can do yourself at home. If you haven't already, perhaps you'd enjoy some of his books while you are making your decision.
Praying for you and trusting He will show you the way.
Blessings, A
