Chocolate Improves Cough: It’s a Real Study

Chocolate

If you are experiencing a cough due to a cold or another respiratory condition, which would you rather take to relieve this symptom: or cough syrup? That’s a silly question, isn’t it!

Chocolate improves cough?

The results of a new small study from the University of Hull in Yorkshire, England indicated that individuals with a cough who enjoyed a chocolate-based medicine recovered more rapidly than did those who were given a regular cough medication. The authors suggest that cocoa has properties that are geared toward relieving inflammation and irritation.

A total of 163 people who had a cough were enrolled in the study and randomly assigned to take either a codeine-based medication or a chocolate-based product. Those who took the chocolate product reported a better response—greater reduction in cough frequency, less disrupted sleep, and better overall health status—than those who took the codeine product.

Past studies of chocolate and cough

This is not the first time chocolate has been hailed for its ability to help with a cough. In a 2005 study conducted by a group from Imperial College London, the authors reported that theobromine—an alkaloid in cocoa–was effective at suppressing cough in both animals and humans.

In another study published in 2017, a team of researchers from various British institutions noted that theobromine was more effective at suppressing cough than was placebo. The participants were given 1,000 mg theobromine in this trial. In comparison, one ounce of unsweetened dark chocolate has about 450 mg of theobromine, sweet dark chocolate contains about 150 mg, and milk chocolate has about 60 mg.

Theobromine is a mild stimulant that also is known as a diuretic and for its ability to dilate the blood vessels (and thus improve blood flow). Some researchers have explored the possibility of using theobromine to treat high blood pressure.

Before you run to the store to stock up on chocolate, it’s important to point out that these studies did not use chocolate bars. For now, it appears that chocolate contains ingredients that have an ability to suppress cough. However, more research needs to be done to determine exactly which components may have this ability, how much is effective, how it should be delivered, and other factors.

Bottom line

If you experience a cough, you may be tempted to enjoy a piece of chocolate. It could help your cough, it could just make you feel better because it’s chocolate or both. We will leave it up to you!
