Re: Hydrogen Peroxide:
I’ve brushed my teeth with it for some time, off and on.
I know my dil had my son and their boys gargling with apple cider vinegar when someone in his unit tested positive back in the early days of the virus. He’s lost some people - one last week, funeral was today. 57 years old, 40 years service in military. :-(
Very sad. Did the person who died have other conditions?
Doing neti regularly is helpful in any case as preventive to wash out virus/bacter from nasal cavities, then gargling with similar salt water. Straight vinegar sounds very harsh on the mucus membranes! I have a home made mouthwash using pepperming, spearmint, thyme, and wintergreen essential oils. Varies according to my mood. Plus of course water, a bit of 180 proof (1 T to 16 oz water) and a bit of caclium carbonate. Gargling with something like that should do the trick. People can use other Eos like Euc, oregano (gack just a little of course). I use about 20 drops to 16 oz of water and even then dilute the mouthwash in a cup with water.
Many EOs are so potent that even a few parts per million can kill stuff, did research a long time ago about it.
