https://holistichealth.one/nano-colloidal-silver-maker-usb Colloidal Silver is the safest, most potent natural antibiotic! Whole Foods has been instructed to stop selling it because it kills pathogens like Covid Viruses. You can get a colloidal silver maker and make it for pennies per gallon using distilled water. I always have a natural antibiotic that works for internal/external infections that doesn't wipe out beneficial bacteria. #colloidalsilver #silver #antibiotic #antiviral #survival
