Well, these folks using the foot baths may well be getting a positive effect from them. A friend of mine who provides them for her clients has told me stories of the varieties of things she has seen in the water -- not just different colors, but things that have appeared to be almost parasitic in nature. It's just that I haven't seen any solid science or evidence behind it to be comfortable to do it myself, nor to promote it. Nor am I certain that it will not produce a negative effect with its use, either short-term or long-term.

There are so many variables, including the user's chemical make-up, the quality and material of the instrument being used, etc. And there's always the possibility that what may have been very good originally, could be used by someone less knowledgeable and informed, unwittingly causing more damage than good.
