Dr. McCullough has been advocating gargling with a dilute (2 tsp/8 oz water)solution of OTC povodine ( Betadyne) for months. States it reduces viral( any type) replication in the upper respiratory tract ( should be especially effective on omicron then)and also using dropper to cleanse nostrils twice a day. He cites a study showing this and says this has been standard practice with some dentists for years. He says to prepare a new solution daily rather than keeping it on the shelf.

Or you can just make your own HCQ and take a dose everyday mixed with some tonic water. We have been doing this for a week now along with the army of daily supplements we take. So far not a sniffle for the past two years.
