Which herb's berry is used and has diuretic and carminative actions?

• A. Lavandula angustifolia
• B. Leonurus cardiaca
• C. Juniperus communis
• D. Iris versicolor

Answer: (C)

The berry of Juniperus communis is used for both diuretic and carminative actions. The dried ripe berries contain volatile oils rich in terpenes that promote increased urine production and help relax intestinal smooth muscle, which reduces gas and abdominal cramps. This combination makes juniper berries a traditional choice for supporting urinary function and digestive comfort.

Other herbs listed are associated with different main actions or parts. Lavender’s useful part is the flowering tops, not the berry, and its role is more about soothing and mild GI comfort rather than a primary diuretic effect. Motherwort is known for gynecologic and cardiac-rely actions rather than diuresis or carminative effects. Iris versicolor is used mainly as a purgative, not as a diuretic or carminative. Thus, juniper berries uniquely fit the criterion of a berry with both diuretic and carminative actions. Keep in mind juniper should be used with caution, especially in pregnancy or kidney issues, and typically in short-term, low-dose applications.
