Should be no problem - a very large portion of tinctures contain alcohol as a preservative and/or part of the tincture making process. Add 1 part mullein extract for even better results. The Clear Lungs product mentioned comes in capsule form and is not intended to be nebulized.
When you get a really bad infection, such as I have seen happen shortly after heavy chemtrails, adding oral oil of oregano gelcaps and olive leaf extract gelcaps can help, as can echinacea. There has been some bad crud making the rounds in recent years and sometimes it takes quite the natural arsenal to win the day. I don't want to seem like a tinfoil hat type, but I have seen the really tough stuff happen repeatedly after heavy chemtrails on at leat three occasions.
