Liquorice

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

Root of leguminous herb is used.

Content: essential oil, flavonoids, tannins, saponins, hydroxi-coumarins....

Unproven effects: anti-ulcerative and expectorant.

Indication after Commission E of German Ministry of Health: gastritis, gastric ulcer, cough, bronchitis.

Because of mineralocorticoid effects, Pseudoaldosteronism, Hypokalemic palsy, Hypernatremia, Edema, Heart arrhythmias and Arterial Hypertension, a longstanding use or abuse of licorice may be a cause of severe health disorders.

May be a cause of abortion and premature labor if taken while pregnancy.

Since it has anti-prolactin and estrogenic effects, decrease of milk production can occur within the first weeks after birth. Reportedly, one case of hyperprolactinemia has occurred.

There is no proof on its galactagogue effect.

Glycyrrhizin is responsible of many effects of Licorice which is excreted in small amount into breast milk. Two infants younger than one months were severely intoxicated (lethargy) after their mothers had drunk an daily average of 2 liters of a beverage containing a mixture of Licorice, Fennel, Anise and Goat's rue. It was assumed to be related to anethol contained in the fennel and anise.
