I guess I should add that I don't know about all that stuff on the page. It seems a bit extreme. But I do believe in the healing properties of salt... anybody who's swam in the ocean likely will as well.
Also, good quality unrefined salt (Celtic sea salt is good too) is important. It's like a mineral supplement, and is loaded with trace elements as well.
Dr. Mercola's into it, but who knows if he's getting a cut or what: http://www.mercola.com/forms/salt.htm
I say, try it and see how you feel. Then keep it if it works for you or chuck it if it doesn't.
