Is it really true that suspended or "colloidal / ionic" silver is anti microbial? that say copper is also anti microbial in normal metallic form, also atomised citrus oils. I don't know where i read these things or why i remember them.
Yes for silver and copper. To what extent I do not know (= I do not know what dose to use and how - sprinkle on surface?).
Noteworthy, copper is also used on intrauterine contraceptive devices as well. They are designed to have specific surface area to release copper cations in order to kill (or at least inhibit) sperm and therefore fertilization.
Citrus oils - seems so. Here is one link to abstract about it:
http://www.ncbi.nlm.nih.gov/pubmed/23381618Though the concentration looks bit high compared to for example antibiotics.
As if to use colloidal silver by ingestion, I would say no. I do not use it. You can turn blue from high doses.
Ok, seriously, that's true.
And in the end, all of it would sound differently if someone would try to sell colloidal lead and try to say its beneficial.
