There's also alternative cures using H2O2, hydrogen peroxide.  If you get the food grade, 35% stuff (very powerful) then dilute it, if you take it when you're sick, it acts like a "healthy" version of chemo.  Gives the body oxygen/energy while killing parasites and other junk.  Using this with vitamin/mineral supplementation would help a lot of people.

Most importantly, bacteria do not develop resistance against ClO₂ because it reacts with biological thiols, which play a vital role in all living organisms [8]. ClO₂ kills microorganisms via direct action on the cellular membrane and through disruption of fundamental cellular processes [9].

Barnhart et al. [10] suggested that appropriate disinfectants could be administered via the oral route during pre-slaughter feed withdrawal to reduce foodborne pathogens from the gastrointestinal tract. Oral ingestion of ClO₂ at levels up 500 ppm (0.05%) had no toxic effects in chickens and pigs [11., 12.] and did not influence palatability of diet or feed intake [11], although it did show strong bactericidal and virucidal activity. Additionally, a case study of ClO₂ administered with drinking water revealed improved feed conversion ratio in broilers with reduced mortality [13]. However, to the best of our knowledge, no studies have tested the effects of ClO₂ administration with broiler diet. Therefore, we investigated whether supplementing broiler diets with ClO₂ powder would affect intestinal microbiota, thereby improving nutrient utilization and feed efficiency, and reducing odorous gas emissions from broiler excreta.

As shown in Table 3, dietary ClO₂ had no significant effects on the number of ileal Lactobacillus and Bacillus bacteria (P > 0.05); however, it led to significantly increased numbers of yeast and mold (P = 0.002). In contrast, ClO₂ at a rate of 0.1% of the diet significantly decreased the number of ileal E. coli (P < 0.01). There were no significant differences among dietary treatments for ileal Salmonella concentration. In the cecal digesta, the concentration of Lactobacillus bacteria and yeast and mold remained unaffected in response to dietary ClO₂ supplementation, although significant reductions in the number of Bacillus (P = 0.005), E. coli (P < 0.01), and Salmonella (P = 0.002) were reported. Dietary supplementation with ClO₂ had no significant effects on the pH of ileal and cecal digesta (data not shown).
