A chemical found in cocoa could help in treating cough.

Scientists are testing theobromine, an active ingredient in cocoa and chocolate.

They believe the chemical works by inhibiting the inappropriate firing of the vagus nerve, which is a key feature of persistent cough.

If tests confirm that it works, the drug could be available within two years.
