On a practical side, chlorine dioxide is a great hack for avoiding trips to the doctor/hospital.
It seems to kill active/inactive anaerobic pathogens both externally & internally. It costs very little too make & so it's easy & cheap to procure a lifetime's supply.
It works via oxidation & leaves no residue (it breaks down into chloride/salt & oxygen). It also seems to oxidise a lot of toxins & poisons - it's apparently great for food poisoning & detoxing.
It's quite contraversial but it's like Bitcoin in that anyone who's actually used it, becomes an advocate. It works completely differently to bleach (sodium hypochlorite) but is compared to it because you use sodium chlorite to make it. It also has a bit of a chlorine smell to it.
Cahlen talks about it a bit.
