If you are sensitive to it, the daily consumption of excessive amounts of licorice can cause high blood pressure and fluid retention. This is due to the substance glycyrrhizin.
Normally, glycyrrhizin is broken down and excreted in the body. But if you eat a lot of licorice daily, you can take in more glycyrrhizin than the body can remove. This can lead to high blood pressure. The experts recommend taking no more than 200 grams of licorice per day. Note that this is an average. The amounts vary depending on the strength of the licorice.
If you already suffer from high blood pressure, do not eat licorice daily. The same goes for small children and pregnant women. Enjoy it, but enjoy it in moderation.
