Have you ever experienced this foot bath yourself? It is not just the color of the water that is important, it is the thick foam and muck that is on top of the water that is unique to each person's state of health. The smoker who sat next to me had black/brown foam and yeast and I and the healthy guy who sat next to me on another occasion had light brown muck/foam just like mine. I had a candida problem and sure enough there was candida/yeast on the top of mine but none on the guy's sitting next to me who didn't have a problem. I would like to see a photo line up of anyone I give a foot detox bath along with a rundown of their health problems and you will see the difference in each bath, maybe someone else could do this because I am not that organized. Plus I did this at a group of MD's clinic who also research and utilize alternative medicine so the MD's believe in it. Try one foryourself and you will be a believer.
