Severity of attacks correlates with serum potassium level.4 It is known that the chronic use of liquorice causes symptoms similar to the mineralocorticoid secretion (apparent mineralocorticoid excess) syndrome, leading to findings such as hypertension, hypokalaemia, metabolic alkalosis.5 So far about 40 cases of hypokalaemic paralysis due to liquorice use have been reported in the literature.
