Sodium chlorite reacts with mild acid (such as 4% hydrochloric--the same acid in your stomach, or phosphoric acid or citric acid or vinegar or lemon juice, doesn't really matter that much) to release chlorine dioxide, which is an oxidizer similar to hydrogen peroxide but is not toxic to healthy tissue in the mild concentrations given in the directions on the Jim Humble website. It is, however, very effective against various pathogens including viruses, anaerobic bacteria, fungus, yeast, parasites, etc.
Bleach is sodium hypochlorite, which is toxic.
