Indeed he said it does not leave chlorine in the body, besides the doses of the protocol are very low. You can't compare it with industrial use, it is now adjusted to biology use, by mixing it and then oxidizers break down to natural.
He was also saying it is the same with ozone, it can make a hole in a latex glove, but they use the ozone IV's in the blood, the blood is the carrier for oxygen and we need it.
I hope I remembered this right otherwise please make sure to listen to the link.
