Worthless.
From the Mayo Clinic:
Colloidal silver isn't considered safe or effective for any of the health claims manufacturers make. Silver has no known purpose in the body. Nor is it an essential mineral, as some sellers of silver products claim.
I’ve sprayed it into my mouth when I felt a sore throat coming on. It’s always worked for me.
Interesting, what does the mayo clinic to see about global warming caused and health effects? What does the mayo clinic say about chopping off your penis? What did Mayo clinic say about staying away from eggs a few decades ago? What did Mayo clinic say when the whole world is recommending a high grain diet?
Just because it’s mayo clinic, doesn’t mean you can trust it
I’ve used for colds for ten years. Gargle at the first sign of sore throat and swab nose. Kills the cold in 2-3 days max. Sorry Mayo I like your site, but you’re wrong on this.
Have you ever used colloidal silver?
I had a sinus infection for 3 months, 3 antibiotic Dr. prescriptions NO RELIEF.
Used colloidal silver and did a sinus flush, gone in 30 minutes - it WORKS FOR ME!!
Before there was refrigeration, the dairy farmers put a silver dollar in their milk cans so the bacteria would be killed and keep the milk safe to use.
The wagon trains put a silver dollar in their water barrels to keep the bacteria out and the water safe.
Look to the old people and find out what they did.
