Which herb is indicated for anxiety, palpitations, and menstrual disorders?

• A. Iris versicolor
• B. Juglans nigra
• C. Leptandra virginica
• D. Leonurus cardiaca

Answer: (D)

Leonurus cardiaca, or motherwort, fits this triad because it combines nervine calming effects with gynecologic support. As a classic nervine, it helps ease anxiety and related palpitations by calming the sympathetic overactivity that can accompany stress. At the same time, it acts on uterine smooth muscle with antispasmodic and toning actions, which supports regular menstrual function and can relieve dysmenorrhea. This dual action—nervous system soothing plus uterine support—makes it particularly well suited for someone experiencing anxiety and heart- racing feelings alongside menstrual disturbances. The other herbs listed don’t share this combined profile: iris versicolor is more aligned with digestive/skin-nerve issues, black walnut is mainly antimicrobial/parasitic-clearing, and leptandra virginica is a hepatic stimulant, not a nervine or uterine regulator.
