There are treatments that purport to pull toxins out of your body during an electric foot bath. Supposedly the different colors in the water correspond to different toxins eliminated from your body through your feet: black shows liver detoxing, dark green from your gall bladder, orange is detox from the joints…
Are the claims true?
No.
Of course not. It’s a scam.
As an almost absolute rule, wherever you see the word “detoxify” or variants thereof you are dealing with a scam.
As good as gold … Fool’s Gold, that is! :smack:
Those whirling colors in the foot bath will suck the dirty old green, and other folding colored paper right out of you billfold! 
Is there someone who could write a clear, concise explanation why this is a scam (and maybe explain how the water turns dark) so I can print out this page and show it to some people who I are taking the treatments?
Thanks in advance.
Is this a good start?
A good quote:
“Thinking back to GCSE chemistry, it seemed likely to me that it was rust rather than toxins, since they have, after all, got a pair of metal electrodes in a salt water bath with a current passing across them. And so we set up, on a kitchen table, a bowl containing salt and water, with two metal nails attached to a car battery. And what do you know: our water goes brown too, with a nice sludge on top. Could this be the same brown as the Aqua Detox water?”
Which pretty much explains what the thing is doing.
Thanks, Valgard, and to all other replies as well.
