For more than a year now, I have been taking a maintenance dose of four drops of chlorine dioxide water purification drops every morning and every evening, and I am feeling better, but even better than that, I am no longer allergic to bee stings. I was stung by a bee last weekend, and it hurt at first, but I didn’t get the painful allergic reaction and it was gone in a couple of hours. Talk about chlorine dioxide side effects, you just keep getting better.
