There is sweet news for chocolate lovers. An ingredient in chocolate just may hold the cure for persistent coughs.
British researchers say the ingredient, which is found in cocoa, is nearly a third more effective in stopping persistent coughs than codeine, which is the main ingredient in many cough medicines.
The discovery could lead to more effective cough treatments.

The researchers say the chocolate ingredient also causes no adverse effects such as drowsiness.
