“From a snake oil salesman. Especially the colloidal silver. “
Correct. It’s a topical antiseptic. You may as well drink hand sanitizer.
Colloidal silver acts as a very strong anti fungal/antibiotic. The US military makes some uniforms with silver thread in the cloth to help prevent infection from gunshot wounds when the cloth gets pulled into the wound.
I put my 94 year old mother on colloidal silver because of constant UTI’s and she didn’t get another one for a year.
Whenever our chickens get sick I put colloidal silver in their water and they recover very quickly.
In the old days people going west settlers would put a silver dollar in the water barrel to keep the water from developing algae and bacteria.
We keep a one oz silver bar in both levels of our Berkey water filter because its by a window and it began to grow algae. Now it never does.
You are not going to turn blue or have any bad side effects from taking properly made colloidal silver.
