Keep it in mind the next time you get a bad chest cold...
I will.. BUT, I haven't had ANY cold in maybe 15 years..and don't think I ever had one in my chest. As I recall they were more in head/nasal area. I do have chronic year round allergy problems... mold, mildew, various pollens, etc. and now and then a sinus infection. I always am interested in trying varous OTC remedies. I do heavy /big time natural preventive measures
