He was right! Same with UV light blood cleansing. It works! I like this brand. Its what hikers and campers use to purify their drinking water. If we are mostly water and its safe to drink, it makes sense it will purify your lymph of pathogens as well. None of this is rocket science. It won't clear your body of metals. Zeolites are excellent for that. Use the CLO2 short term as its so powerful, it may affect some beneficial micro flora so make sure to supplement with probiotics, yogurt, kimchi etc if using it for a detox.
