Hi, Garnet,

Your questions are cutting-edge material that Searle could
have answered but may be lost knowledge now, I bet.
The WaterOz product should be benign since, after all,
manganese is an essential trace mineral.

Tetrasilver tetroxide is available in several forms depending on its intended 
use. The topical ointment consists of 2%
Ag(4)O(4) in a jojoba bean oil vehicle. The label cautions
officially against ingesting it, of course. It is sold in this
country without a prescription for around eighteen dollars
a tube and can be ordered over the internet. It is called
Tetrasil. Launch your search engine on keywords:
tetrasil, silver, ointment and you should find the website.

Again, I emphasize, it is officially labelled as an external-
use-only preparation. Any other use would be experimental.

Best regards,

Matthew
