There doesn't seem to be much interest in this chemical as a mouthwash or for topical use. Sodium chlorite is an antiseptic, that is not the issue. There are better antiseptics for human use. Plain old saltwater is a great mouthwash, with no danger of harming yourself either. Salt water also makes a fantastic eye wash.
It is the claims that this sodium chlorite, is some kind of cure all, that is the problem.
They've had 14 years to "investigate further" and have come up with nothing to support the claims that JH and his fellow scammers are making. Long enough IMO. There will always be those that cannot accept that they have been duped, and will go on hoping for something they can latch onto, rather than face the fact that they have been fooled.
Older animals benefit from clean water, and Iodine is a good water purifier, and is also an element that the body needs, both animal and human.
Old dogs do very well with DE added to their water as well.
Does this mean that Iodine or DE is a cure all, no.
