It works on viruses also. Several weeks ago my cousin in NC came down with the flu. I told him to take a tsp of 250 ppm colloidal silver three times a day in a small sip of water and elderberry tincture. By the next day his fever was gone and he felt 100% better. He was really sick.
We take silver and elderberry tinture everyday during cold and flu season as a preventative or if we start to feel sick. It will stop almost anything before it gets going.
My mom was getting one UTI after another so I finally put her on a daily regimen of silver and she didn’t get another infection for almost a year.
Speaking of oils, I tried spraying peppermint oil on a couple of corners in the house where spiders seem to like to take up residence in my house, and after hitting it with peppermint they've never come back.
They're probably under my bed's headboard now. LOL
