摘要

Objective: To report a case of hypertension secondary to ingestion of licorice root tea.Case Summary: A 46-year-old African American female with newly diagnosed stage 1 hypertension presented with a blood pressure measurement of 144/81 mm Hg and a reduced plasma potassium level of 3.2 mEq/L. The patient attempted lifestyle modifications prior to initiating an antihypertensive agent, but at a follow-up appointment, her blood pressure remained elevated. A current laboratory panel revealed a depressed morning plasma aldosterone concentration (PAC) of 5 ng/dL and low morning plasma renin activity (PRA) of 0.13 ng/mL/h. Later it was revealed that the patient regularly (1-2 cups/day) consumed "Yogi Calming" tea, a blend of herbs, including licorice root. The patient was advised to discontinue consumption of the herbal tea, and at a subsequent appointment, her blood pressure was 128/73 mm Hg and her laboratory panel had improved, including serum potassium concentration of 4.1 mEq/L, PAC of 6 ng/dL, and PRA of 0.19 ng/mL/h.Discussion: Excessive consumption of licorice has been well documented to cause pseudohyperaldosteron-ism, characterized by hypertension, hypokalemia, and suppressed plasma renin and aldosterone levels. Glycyrrhizin, the active ingredient in licorice, inhibits ll|3-hydroxysteroid dehydrogenase type 2, an oxidase responsible for the conversion and inactivation of cortisol to cortisone. Chronic ingestion of licorice-containing foods has been demonstrated to cause pseudohyperaldosteronism. These include soft candies, lozenges, and dietary supplements, but licorice-containing teas have been infrequently described. Based on the Naranjo probability score, our patient's hypertension appears to have been a probable licorice-induced reaction secondary to a licorice-containing tea.Conclusions: Herbal and dietary supplements are frequently consumed by patients without full knowledge of the contents of the products or the impact on their health. In clinical practi...
