The compound of ‘glycyrrhizin’ contained by the Licorice root is 50 times sweeter than sugar which makes it ideal component for the beverages and confectioneries. This root has its medicinal value and even termed as effective in relieving spasms and inflammations.
If we consider this root for the lactating mothers then it is hard to claim clearly as not as such information is available about the effects Licorice has for the mothers. US national institute has proved that it is not beneficial for the lactating mothers as it can interfere the breast feeding and can reduce the milk production. It is recommended to mothers only to treat the oversupply or when weaning but if you are nursing then you must avoid it.
Some studies have claimed that the consumption of this herb can lead to many side effects like the headaches, high blood pressure, heart ailments and even swelling due to water retention. Pregnant women are also asked to avoid this herb as it can affect the growth of child in the womb and even can cause miscarriage, stillbirth or preterm labor
Studies have shown that consumption of this herb in the herbal tea of quantity more than 2 liters for the mothers that feed their infants can affect the health of infants and make them weak and weary. This root may reduce the level of potassium in the body which can be fatal in certain cases for the mothers that are on the diuretic medications
Hence it is not at all recommended for the lactating mothers to consume large quantity and prolong use of licorice and mothers must consult the physician before taking any herbal products that can be harmful for breastfeeding.
