@robbie21 - I like how you are getting at the difference between homeopathy and broader ideas like natural remedies and alternative medicine. The terms are often used interchangeably, but they really aren't the same.
Using arnica cream to treat muscle strain is not homeopathy - it's a natural remedy. Taking a microscopic dose by ingestion is homeopathy.
As a general rule, natural remedies are untested and should be used with caution and in consultation with a knowledgeable practitioner. But you can think that homeopathy is a load of bunk (it doesn't make intuitive sense to me, but I'm no expert) and still be a fan of other natural remedies. I like evening primrose oil for labor preparation, for instance.
