Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK
researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping
coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could
lead to more effective cough treatment. "While coughing is not necessarily harmful (有害的) it can have
a major effect on the quality of life, and this discovery could be a huge step forward in treating this
problem," said Professor Peter Barnes.
Ten healthy volunteers (志愿者) were given theobromine, codeine or placebo, a pill that contains no
medicine, during the experiment. Neither the volunteers nor the researchers knew who received which
pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and
as a sign of how well the medicine is stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a
cough was around a third higher than in the placebo group. When they were given codeine they need only
slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity (神经活动), which
cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side
effects such as sleepiness.
