The statement below which appears on the silver-colloid website seems to be
the source of some controversy.
Ingestion of highly concentrated forms of ionic silver can cause
argyria, a permanent discoloration of the skin. The
likelihood of argyria becomes significant for ionic
silver concentrations above 100 ppm. Typical ionic
silver products contain between 3 and 20 ppm of ionic
silver which would not cause argyria."
It seems to be technically accurate in every detail.
Highly concentrated forms of ionic silver above 100 ppm are not made by home
hobbyist machines. This is a class of product that is manufactured
commercially and sold as "Ionic Silver" by companies such as WaterOz.
Technically, the WaterOz product is silver citrate, but the company refuses
to identify the anions used in their "ionic" products. I have it on good
authority that the owner of WaterOz in fact has argyria from using his own
product. "On good authority" means this information came from a personal
friend of that individual.
"Typical ionic silver products contain between 3 and 20 ppm of ionic silver
which will not cause argyria." Most all home made ionic silver and
commercially sold ionic silver products fall in this category. We are not
aware of a single case of argyria from this class of product.
Would someone please explain what is controversial about the above
statement?
