I would like to point out that because of Black Agnes who was one of the first people here to wonder if iodine helped at the very beginning...i have been using pvp iodine long before mentioned by Korys group.
Cvs sells a packaged swab of it. I use it after every drs appointment i have.
I had to see a lung dr who treats covid people. I was terrified he would give me covid. I was in the bathroom afterward swabbing my nose while laughing at the whole circus of this. Then i swabbed again in my car
Amazon has cheaper versions but i feel safer with cvs brand. None are dried up. They are dripping in the iodine
