Health Question

Can eating too much black liquorice be bad for you?

Yes, particularly if you're over 40 and have a history of heart disease or blood pressure test, or both.

Eating more than 57g (2 ounces) of black liquorice a day for at least 2 weeks could lead to potentially serious health problems, such as an increase in blood pressure and an irregular heart rhythm (arrhythmia).

For most people, liquorice found in foods is safe to eat and safe when consumed in large amounts in medicines for short periods of time.

General health advice about black liquorice

No matter how old you are, you should avoid eating large amounts of black liquorice over a short space of time.

Black liquorice can interact with some medications, herbs and dietary supplements.

Get advice from a Doctor or your local hospital if you have questions about possible interactions with a medication or supplement you're taking.
