That’s good stuff, and while I think of it, I’d like to put in a plug for humble hydrogen peroxide, add a 500 ml bottle to a 1/2 gallon humidifier, let it run overnight, hydrogen peroxide is one of the most potent antiseptics known to man and as you breathe in the combination moist air with Hyd-Pxe, it WILL kill germs.
Also, lay on your side, and have someone put a dropper of Hyd-Pxe into your ears, not only will it kill germs, but it will get rid of any ear wax in there too!
And I subscribe to the salt water regimen too.
Yep, hydrogen peroxide is good. So is using good old chlorine bleach on surfaces, while washing bedding with a bit of chlorine bleach added to kill the nasties. Also drops of essential eucalyptus oil (natural antibiotic and refrigerant) in your humidifier can cleanse he air and soothe the respiratory tract - it’s like putting Vicks into your vaporizer, but cheaper. For an even cheaper alternative, and also a nice houseplant and great seasoning for lamb, pork and venison, there’s rosemary, which is heavy on rosmarin, which happens to be basically mentholatum, which is the same as eucalyptus oil and you can just peel needles off as needed.
