Which herb lowers the concentration of blood pressure medications and diuretics?

• A. Ginseng
• B. Licorice
• C. Garlic
• D. Ginkgo

Answer: (B)

Licorice interacts with blood pressure meds and diuretics by causing mineralocorticoid-like effects. The glycyrrhizin in licorice promotes sodium and water retention and potassium loss, which tends to raise blood pressure and counteracts the effects of diuretics and antihypertensive drugs. As a result, the overall blood pressure–lowering effect of those medications can be reduced, making it seem like the drugs aren’t working as well. For patients on these therapies, avoiding or limiting licorice-containing products helps maintain the intended medication effect. Other herbs can interact in different ways, but licorice is the classic one that counteracts diuretics and BP meds through its mineralocorticoid-like action.
