This seems to be one of the easiest remedies I have heard of for a cough. I don’t think you can go wrong with it.
Honey and Eucalyptus Cough Syrup
Put honey into a small glass jar or container, then add a few drops of eucalyptus oil. Stir well. Take a spoonfull when the cough comes. If needed, take a second time.
Note: pure eucalyptus oil can eat through plastic conatiners, so I recommend using only glass for storing.
