Be careful with Sodium Chlorite. Yes, you DO have to mix it with citric acid on a 1:1 ratio, but you need to do thorough research before you consume it.  Too much at once or at first can make your blood toxic and kill you (found this out the hard way). Sodium chlorite on its own is NON TOXIC to the body, however, you also have to follow up larger doses with activated charcoal or something else that will absorb the "die off" in your system. Does it work for the flu? I have never tried it for that. I mainly used it to detox. And no, sodium chlorite is NOT bleach, but it does turn into chlorine dioxide in your body and tastes like pool water. And yes, it has been used to CURE MALARIA in an African village where its success rate was 100%. http://www.healing-yourself.com/Sodium-Chlorite.html
