Cinnamon and honey, eat it with a spoon and it’s supposed to sooth your throat and help you stop coughing. My niece was coughing all the way to school once, and I just gave her a dixie cup of honey and cinnamon and she stopped coughing. And it tastes really good too.
I’ve heard of this before, though I can’t recall where. I haven’t personally had much luck with it, but I can vouch for it tasting very good.
