For many years I would be bothered with bronchitis or laryngitis (or both) every Spring. I started using a nebulizer with silver at the first sign of lung problems and that would prevent any further problems.
I still use the nebulizer but another way I do mostly now is use a cool mist humidifier. Has to be cool mist since the heat changes the silver. At the first sign of coughing up stuff, I put silver in the humidifier and close the door to whatever room I am in and simply breathe the air. Eliminates my problem right away.
I learned all this right here on this forum.
I also put silver on any cut or scratch right away and do not have much of a problem with soreness.
