Best treatment for chronic cough = Dark chocolate (low sugar)It's more effective than codeine and tastier :-)http://www.drgreene.com/21_1880.html"The codeine was effective at preventing coughs, but the cocoa ingredient was 33 percent more effective, preventing cough effectively for 4 hours, and had no side effects."http://www.drweil.com/drw/u/id/QAA352799"Though my preference would be to eat an ounce or two of dark chocolate with at least a 70 percent cocoa content...I?m not surprised to hear that chocolate may yield yet another health benefit. In addition to theobromine, it provides polyphenols, the same kinds of antioxidants found in red wine, and the fat it contains is stearic acid, which doesn't affect cholesterol levels. "
