When I used the homemade ionic footbath, what I got each and every time with my feet in the water was bright red (like blood) coloring. (and a lot of it) So I quite because my symptoms (laboreous breathing) were not improving. It turns out I had developed severe asthma and it took months of herbs and diluted hydrogen peroxide inhaling ( info. found on earthclinic) to bring me to 90% normal. I still can't run or talk and walk much at the same time but I can walk (slow like a turtle) 1-2 miles and I can do moderate exercising.
