There are many scams going around. So don’t use Colloidal silver if you are looking for a remedy, or for that matter, iconic silver. Essential oils are put in a diffuser, and spread their smell into a room. Lavender essential oil may be effective against germs, but I won’t know until I try and I can’t have peppermint. Cajuput oil is cited in the Ncbi article I found, whose link is posted below. Cinnamon may also have antibacterial related properties, only because of its chemical makeup. Eucalyptus is another possible oil to use, along with sage oil. I may experiment with these, since I am at high risk to become infected with coronavirus but seeing as I have perfect type 1-diabetes.
