Licorice is a divisive candy — of us each prefer it or hate it. Traditionally made with the inspiration of the licorice plant (Glycyrrhiza glabra), this tender, chewy candy boasts a predominant ingredient that has been used to soothe sore throats and assist digestion since historic Greece.
Nonetheless licorice lovers couldn’t discover that the candy has the potential to mess with positive organs and medicines. Whether it is eaten typically, in huge parts or with positive remedy, licorice could trigger crucial unfavorable results. (That’s assuming the candy is flavored with precise licorice root and by no means a similar-tasting ingredient, paying homage to anise.)
So how does licorice impact the physique and work along with medicines?
One among many culprits is glycyrrhizin (pronounced gliss-er-EYE-zin). This compound, current in licorice, could trigger the kidneys to retain an extreme quantity of water and sodium whereas shedding an extreme quantity of potassium, Joan Salge Blake, a vitamin professor and registered dietitian nutritionist at Boston Faculty, suggested Keep Science in an e mail.

Glycyrrhizin blocks an important enzyme throughout the kidneys — known as HSD-11β — which normally prevents the stress hormone cortisol from disrupting kidney carry out. The enzyme primarily diffuses cortisol by altering it into one different hormone, known as cortisone. With out this enzyme, cortisol latches onto receptors throughout the kidneys, inflicting the organ to hold on to water and sodium and spew out potassium.
When the kidneys retain sodium and water, the amount of blood circulating throughout the physique will improve. Which means additional fluid pushes in opposition to the partitions of blood vessels, resulting in hypertension, or hypertension. This affect can instantly counteract the movement of blood-pressure-lowering remedy, paying homage to ACE inhibitors, decreasing their effectiveness. These interactions impact remedy like captopril (mannequin establish: Capoten).
One different interaction can occur with diuretics, typically often called “water medicine.” These medicines are typically prescribed to lower blood pressure by eradicating additional fluid from the physique — briefly, they make you urinate additional.
One facet affect is that they make the physique lose potassium, an important mineral that helps keep the heart and muscle tissues working correctly. Licorice moreover makes the physique lose potassium, so consuming licorice and diuretics collectively can lead to dangerously low potassium ranges, known as hypokalemia. Indicators embrace muscle weak level, fatigue, and, usually, crucial coronary coronary heart points.
Low potassium ranges pushed by licorice could enhance the possibility of unfavorable results from digoxin (mannequin establish: Lanoxin), a drug used to cope with coronary coronary heart circumstances like atrial fibrillation, or AFib, and coronary coronary heart failure. Digoxin changes the concentrations of minerals in coronary coronary heart cells by blocking a specific pump, and this in a roundabout way causes additional calcium to stay trapped contained within the cells. The extra calcium makes the heart muscle contract with additional energy, serving to it pump blood additional efficiently.
Often, potassium competes with digoxin on the pump it targets, stopping the drug from exerting too sturdy of an affect. Nonetheless, when potassium ranges throughout the physique are low, digoxin binds additional strongly to coronary coronary heart cells, with toxic outcomes.

This occurred to an older man whose case was reported throughout the journal Cardiology. The individual expert digoxin toxicity after using a pure laxative that contained licorice. The licorice lowered his potassium ranges, enabling digoxin to behave too powerfully and leading to congestive coronary coronary heart failure.
Other than the medicines talked about above, many alternative remedy can be affected by licorice. When you’re taking any medicines, it’s best to always look at alongside along with your doctor or pharmacist sooner than consuming merchandise that comprise licorice, Salge Blake acknowledged.
It’s powerful to say what a “protected dose” of licorice could also be for a given particular person, partially on account of licorice can be found in a number of merchandise. Each candy, complement and tea might comprise utterly totally different ranges of glycyrrhizin. Plus, of us’s sensitivity to glycyrrhizin varies counting on their physiology and current medical circumstances, paying homage to hypertension.
For individuals who discover themselves not taking any medicines, quite a lot of pointers advocate limiting glycyrrhizin consumption to 100 milligrams per day, or roughly 2.1 to 2.5 ounces (60 to 70 grams) of licorice candy. Previous that, you may experience indicators paying homage to problems, hypertension or coronary coronary heart points.
Nonetheless, the U.S. Meals and Drug Administration warns that “if you’re 40 or older, consuming 2 ounces (56 grams) of black licorice a day for on the very least two weeks may land you throughout the hospital with an irregular coronary coronary heart rhythm.”
The underside line is: With licorice, moderation is important.
Even typically consuming licorice teas or pure dietary dietary supplements containing licorice can have damaging outcomes. In a single case, a woman developed dangerously low potassium ranges and hypertension — resulting in scorching flushes, sweating and problems — from consuming six cups of licorice tea a day, in accordance with a report printed throughout the journal BMJ Case Experiences. She stopped consuming licorice tea and her indicators disappeared two weeks later.
“The good news is that almost all licorice-flavored merchandise throughout the U.S. don’t comprise precise licorice root,” Salge Blake acknowledged. “Instead, they use anise oil, which provides the similar style with out the glycyrrhizin.”
