I totally agree with your statement. If it were necessary to have to agree with every mode of natural therapy, then it wouldn't be "alternative medicine" any longer. It's the fact that we are allowed "alternatives" to our pathway to health as oppossed to a prescription without room for debate. I agree that distilled water is not a good substitute for regular drinking water because of its structure and its purpose which is to cleanse.
What makes me stressed about the natural health industry is that everyone is starting to bring a fast food attitude to their approach and forgetting the holistic law that everything is about "homeostasis", all about being in balance and treating the whole not the part. This industry will soon be just like the pharmaceutical companies that address parts only. Well, enough of me for now. :)
