Natural remedies

There are millions of natural remedies for every problem humanity has, whether real or imagined.  If you are trying to avoid chemicals, then look for these:

Olbas' Pastilles Maximum Strength Cough Drops:  If you have a sore throat, these are phenomenal.  They are made with many kinds of mint and other oils.  They are very strong, in flavor, but they do work.  They also do not dry out the mouth like some cough drops.  I find them useful also for colds.
