Saline Spray - One word. Children. When they are little, your options for decongesting them are close to none. This is it.
Guaifenesin - Why suppress your cough? It is there for a reason. Get the crap out with an expectorant.
Medihoney - My Dad swears by honey. Now, so does the pharmaceutical industry - they made a salve out of it.
Camphor - I put in the vaporizer which runs from October to April. Again, kids.
Lemon Juice - I put this in hot water, tea, and my homemade cough syrup.
Hibiclens - Forget bactine. This will kill anything. Probably even eat your skin off if left on.
UPDATE 3/30/15 - Two cases of strep throat in one month and what's in my medicine cabinet? PENICILLIN.
