Motherwort (Leonurus cardiaca) is an herb in the mint family. Native to central Eurasia, the hearty herb has now spread to North America. Medicinal use of motherwort dates as far back as the early Greeks, who gave motherwort to pregnant women suffering from anxiety, which is how the herb reportedly got its name. Motherwort is also used as a remedy for female reproductive disorders. Motherwort contains leonurine, a compound found to promote the relaxation of blood vessel walls . Unlike many other herbs in the mint family, motherwort doesn't smell or taste good and is classified as a bitter herb. In herbal medicine, its leaves and flowers are used, albeit sometimes with a flavoring like sugar, honey, or lemon.
