I never tried it deep in the nose though, only lower nostril. So it could still be higher up. But it hasn’t colonized the lower areas for years. Had it for 5+ years before realizing what it was.

Mind you I have no way of knowing if this is actual medical grade stuff that use in hospitals. But it seemed to work. On multiple mrsa outbreaks too: I had a few instances where it got outside the nose and this got rid of them.

What exactly are you doing with it? I wasn’t quite clear on how you’re going to get it deeper into the nose. I had had the mrsa in the lower nostril so I just used a q tip, but I didn’t get it into the nasal passages. (Nor do I know if it’s meant for such use). I also have congestion at night so I;m interested.

I will say that a jar like this lasts for many uses. If you’re eating honey it’s a small amount, but you don’t need much for topical use.

I would be irrigating the sinuses with it, diluted in warm (distilled!) saline water. I've done this with regular raw honey and haven't been too tempted since.

Well....I guess it’s probably not actively destructive then, I guess the sinuses can deal with it. I’m going to look into this, thanks!

So in your case I guess you’re just diluting the honey in water to a certain degree. But the raw honey was uncomfortable as the reviews suggest.

If you’d like to talk more about mrsa/nasal stuff btw, my email is in my profile.
