Motherwort (Leonurus cardiaca) is an herb in the mint family. It is used as a remedy for female reproductive disorders. For instance, it's purported to help regulate menstrual periods, especially when someone is anxious or tense. Another prominent use for motherwort is as a tonic for the heart (especially heart palpitations), as the Latin word cardiaca (`for the heart`) indicates. In addition to being a source of antioxidants and anti-inflammatory compounds, motherwort contains leonurine, a compound found to promote the relaxation of blood vessel walls. Motherwort may have cardiac-protective abilities. For instance, it's been shown to relax heart cells and to help prevent the blood clots that cause heart attacks. As motherwort affects heart rate and rhythm, it should not be taken with other medication without discussing it first with your doctor.
