Eat chocolate as a natural cough remedy, here’s the study. ROCOCO  is the name of the randomized controlled clinical trial conducted by the  Hull University team , which involved 163 patients. The researchers compared the effects obtained from traditional syrups with those of  medicines containing cocoa . Chocolate-based cough medicines have proven to be more effective. This is because, according to Morice, they would create a coating that  protects the nerve endings  that stimulate the urge to cough. In the individuals analyzed, they were able to reduce both cough frequency and sleep disturbances within two days.

In short, tasting a piece of chocolate slowly can bring relief, but of course the expert points out that it is the way in which the components of the cocoa interact with the other ingredients in the medicine that make it so effective. For the more skeptical, the results are expected to be published within the next 12 months.
