I take a pill for low thyroid - I hear that can cause a cough sometimes. (Can’t recall now if it is the pill, or the low thyroid!) I’ll cough once, and sometimes it turns into 15 minutes of uncontrolled coughing. A dose of Delsym and 3 or 4 cough drops later the cough is gone - but my throat is sore for the next day.
Take one quart screw top glass container
fill with sliced onion (brown, red or white...whatever is available)
Put 4 or 5 table spoons of brown sugar in the top
close lid and let stand for 2 or 3 hours
take a table spoon of the brown liquid for cough
generates enough cough liquid for a day....add more brown sugar next day....depending on the quality of the onions will last for up to 3 days.
