Saying that its superior to anti biotics is false. Anti biotics perform a much wider range of actions that help the body recover and also are much better at killing the bad stuff. The downside is that viruses and the like can become immune to antibiotics over time. This isnt true for colloidal silver. CS also does not work on a alot of viruses out there. It is not a cure all. It's a cure some. The side effect of turning blue or purple is considered major even given the rarity since it is not curable.
If you need scientific studies, just look at my prior post. I posted quite a few. Its only one page back.
"In addition, as it regards this thread, how can it reverse 6 months of bad nutrition causing stunting. Apparently it is also a time machine. "
The original reason CS was brought up was due to worms, not bad nutrition. I think reading back a few pages may help you understand some of your questions and give you some answers.
Anyone that thinks anything is a cure all needs to do more research on their own and find the truth. There is nothing in this world that will cure everything. That's why we have multiple tools at our disposal.
