Okay, Oxypowder is sold as a colon cleanser, I noticed improvement in smell and taste within 2-3 days of using this. It is so amazing what is retained in your body over the years. It is basically high dose magnesium, I take 4 capsules prior to bed.
The oxygen therapy I don't gargle I actually drink, 10 drops in 8oz distilled water but Food Grade ONLY hydrogen peroxide, the other peroxides have too many unknown additives.
I initially was concerned at first that this may be harmful to drink hydrogen peroxide but after lots of research here in the oxygen therapies forum and the net in general I am no longer worried, it can't be harmful to add additional oxygen to your body thus killing off bad bacteria which do not thrive in high oxygen areas. It is also used in alternative medicines with cancer therapy.
