Licorice, or liquorice, contains glycyrrhizic acid that interacts with digoxin and can cause heart rhythm disturbances or even cardiac arrest.

This substance is also present in sweets, cakes, and other sweets. Licorice is often present in beer as well.

Dietary fibers (bran, for example) decrease the effectiveness of the drug, so it is best to take them 2 hours before or after meals. Herbs like senna or St. John’s wort also reduce the activity of digoxin.
