I have also seen these at the chemist. Theres a picture of someone sleeping on the box,and a before and after shot. So when they put the pads on the soles of their feet,the pads were white. When they woke up the pads were black. The black representing the toxins the pads drew out. It costs about $40-$50 dollars, so they are a bit dear.
I just don't know. I am really tired of getting ripped off if you know what I mean, and they are not cheap either!!
I think it would be worth it if it really worked,but I also kind of worry about the increase or enhancement in immune system, as it was my immune system that got me into this mess to start with. It has gone a bit nutty.
I have also posted once on the old forum about some sort of foot bath that draws toxins out,and the water is black or severly sedimented after 30 minutes or so.
People called it "snakeoil". Although I still do not understand why water is black if it is snakeoil?
