If you swab the nasal area out, or as you say snort it, does it need to be rinsed for fear you will swallow it if it hits the back of your throat? Also does the nasal area need to be rinsed afterward? I’ve only used iodine typically to be absorbed through skin
Topically not typically
I think this is why you use PVP iodine versus the other kind.
The ENT that I saw talking about this on the news put it in a saline bottle and just snorted it and you were done.
Every recipe I have seen talk about this from Drs talks about the PVP version.
I dont know that I would want to use this multiple times of day for fear of hurting the nasal passage but for my purpose which is not often I do it.
But really if Soap kills Covid then soap in the nose should work.
