Russ,

Wow, that's great that you guys tested it like that, using a control!! I've been wondering for a while if they help at all....I used some of the foot patches for a week, and they certainly turned dark brown. BUT, the herbs inside them were light brown to begin with, and the things make your feet sweat quite a bit. So I had no way of knowing if the wet, slimy dark brown stuff that I found the following morning (you wear them while you sleep) was simply sweat mixing with the herbs already there, or if it was toxins that were pulled out of my body. I didn't feel any different, so I was a bit skeptical of them. So I find these results fascinating, because it's the same type of scenario.
