Anyone know anything about this? I had an Md (who is also an ND) use it on me, and I am trying to figure out if it is b.s. or not. The first run, with my feet in the bath, yielded tons of nasty looking stuff that I thought were toxins from my body. Then, he ran the machine in the water without my feet, and the water looked almost the same to me, but he claimed it was different with my feet. It could have been, but I got very skeptical when I saw that the color change and debris were there without my feet in the water. If he was trying to con me, I cant imagine why he would show it to me without my feet in the water, I was so amazed up until that point!
