This is a proven grandmotherly cough cure that works for both young and old. It's very easy to make, the only downside is that you have to wait 24 hours before you can consume.
Pick out a large black radish. Wash it very well under running water with a dish sponge (use the rougher side).
In the upper part (where the leaves attached) dig out a hole with a knife. Fill the hole with homemade bee honey. Place the head of radish in a cup to keep it stable and leave it as is for 24 hours.
Take 1 tsp of the honey every 2-3 hours; if it's a more serious cough, take it even more often. The next day, you can make yourself a new dose with another head of black radish to have the grandmotherly remedy on hand at all times.
