As the previous FAQ outlines, there is a potential risk with taking large quantities of licorice in the case of high blood pressure. Blood pressure can also occasionally rise significantly in pregnancy and, if this has been confirmed for you, you will probably be closely monitored and will justifiably be extra cautious about any additional risk and understandably give licorice a temporary break.
Actually, there is no evidence of general risks to pregnancy with moderate intakes of licorice. In the more excessive case, a sequence of studies by a research group in Finland has indicated that heavy consumption of licorice candy by pregnant mothers (high consumption is more common in that country) has minor effects on birth timings and may even have limited consequences for subsequent childhood development. However, these findings relate to sugar- and salt-rich candy consumption, and to daily ‘heavy’ (more than 500 mg glycyrrhizin/week) consumption over many weeks. Neither have these findings been confirmed in any other country. All other evidence points to moderate licorice consumption being safe, and regulatory authorities in Europe, the USA and Australia do not warn against its use in pregnancy. Nor do we.
Here at Pukka however we have your welfare close to our hearts so to take the worst-case scenario from the Finnish study we suggest that if you are pregnant you have less than 3 cups per day of Cinnamon and Licorice and Licorice and Peppermint and no more than 1 cup of Three Licorice tea per day.
