It is still early to be concerned about the cold and flu season. But now is a good time to prepare and stay healthy over the winter months. Pharmacists hear endless stories about personal maladies. We are sort of like bartenders, only we hear stories about phlegm, sniffles and hacks. Our recommendations are well rehearsed: lots of rest, plenty of fluids and some choices from the vast selection in the cough and cold product aisle. I receive many questions concerning the complementary therapies for colds and flus: "Do these things really work?" and "Are they safe?" Many are effective and just as many can be harmful.
