Chocolate: The New Cough Remedy?

Scientists have discovered that theobromine, an ingredient in chocolate, is nearly a third more effective in stopping persistant coughs than the leading medicine. The research, led by the Imperial College in London, showed that theobromine works by suppressing the vagus nerve activity that triggers coughing. The team also discovered that unlike standard cough treatments such as codeine, theobromine caused no adverse effects on either the cardiovascular or central nervous systems.
