Chocolate can help you beat persistent coughs

Chocolate may be a remedy for the common cough, according to new research, writes Roger Dobson.
A compound in cocoa has been shown to reduce symptoms of both acute and chronic coughs.
About 300 people with a persistent cough are taking part in a clinical trial at 13 NHS hospitals where they are being given the naturally occurring chemical theobromine, derived from the raw ingredient of chocolate, twice a day for 14 days. Early indicators are that 60 per cent of patients experience some measure of relief.
Researchers say a daily bar of dark chocolate may contain enough of the active compound to have an effect on a chronic cough.
