Contraindications: with regard to side or undesirable effects, for health purposes it is not recommended to take it for prolonged periods (maximum 4-6 weeks) and at a high dosage because, due to its mechanism of action, which causes an increase in renal cortisol, it can cause an enhancement of minerlcortidoid activity, resulting in excessive water and sodium retention and loss of potassium. The consequences of this can be hypertension, edema, arrhythmias and muscle weakness. Contraindicated in those with hypertension (high blood pressure), in pregnancy, lactation, chronic hepatopathy, in renal failure, cirrhosis of the liver and heart disease. In pediatric age (4 years and older) it should be consumed only as an expectorant and only in the form of aqueous preparations (herbal teas) at a dosage proportionate to the child's weight. Not recommended to be taken with oral contraceptives as these may increase its hypertensive effect (raises blood pressure). Avoid use together with corticosteroids and in heart patients being treated with diuretics. From a dietary perspective, licorice use should not exceed 100 mg per day as a flavor corrector, and no more than 50 g per day of licorice candy should be consumed.
