To a degree they are linked... they both look at the whole person, they both look for the cause. But yes the treatments they use are different. As pp has said, Naturopaths use supplements, vitamins etc. Homeopaths do use a diluted substance that focuses on like curing like. Not every type of complimentary medicine will suit/work for everyone, but you might be surprised how well some 'less popular' modalities work. Ring some up, ask questions or as a PP suggested already, go to a student clinic - cheap prices and can give you an idea of the types of treatment that work for you.
