Is Licorice Root Safe During Pregnancy?

According to the University of Maryland Medical Center, pregnant women must avoid the consumption of licorice. While this root offers multiple medicinal benefits, it also contains glycyrrhizin that can cause health problems like headaches, fatigue, high blood pressure, water retention, edema, and even heart attack!

While only high consumption of licorice root in pregnancy can cause the above health issues, smaller amounts of it may cause side effects like numbness or pain in the limbs (1).

Side Effects Of Licorice Consumption During Pregnancy

Recent studies reveal the side effects associated with licorice root and pregnancy can lead to the following health complications:

  • A high dose of licorice extract during pregnancy may cause a miscarriage or a preterm delivery. A study in the American Journal of Epidemiology links high licorice consumption to a shorter gestation period. Licorice can double the risk of premature birth (4).
  • Experts from Edinburgh and Helsinki universities state that the consumption of licorice root during pregnancy can impair the placenta. The compound glycyrrhizin could allow the mother’s glucocorticoids or stress hormones to reach the baby and adversely affect the fetal brain development. Hence, it can lower the intelligence levels and increase the behavioral problems in the child (5).
