What is it
Motherwort (Leonurus cardiaca, and the related Chinese Leonurus japonicus) is a mint-family herb traditionally used for heart palpitations, nervous tension, and menstrual and postpartum complaints. It is taken as a tincture, tea, or extract. Human clinical evidence is sparse, and most data come from traditional use and laboratory studies.

palpitations and nervous tension
Supplement benefitMotherwort has a long traditional reputation for calming palpitations and nervous tension, and a small open-label study of a Leonurus oil extract reported reduced anxiety and blood pressure in people with hypertension. The evidence is preliminary, uncontrolled, and insufficient to confirm a real effect. Preclinical work suggests mild cardiovascular and sedative actions.
Bottom line: Traditional use and one small uncontrolled study hint at calming and mild cardiovascular effects, but the evidence is too weak to rely on.
Evidence is mixed
Support rests on tradition and a single small uncontrolled study; no robust controlled trials confirm benefit.
