Motherwort (Leonurus cardiaca) is a traditional European herb containing leonurine and flavonoids that may support cardiovascular health through mild vasodilation and negative chronotropic effects. Research suggests it may help reduce mild anxiety-related heart palpitations and support healthy blood pressure levels.
Origin & History
Motherwort (Leonurus cardiaca) is a perennial herb in the Lamiaceae family, native to central Europe, Scandinavia, and temperate Asia, now naturalized in North America. The aerial parts are harvested during flowering and dried at 35°C, with European Pharmacopoeia standards requiring a minimum 0.2% flavonoids expressed as hyperoside.
Research Narrative (Provisional)
Clinical evidence for motherwort is extremely limited, with only one small pilot study administering 1200 mg/day to patients with hypertension and anxiety, showing mild cardiovascular effects. No PubMed PMIDs or large randomized controlled trials were identified in the available research, with most evidence derived from preclinical animal and in vitro studies.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.

Leonurine's bioavailability is not well-studied in humans."}
Reported Mechanism (Provisional)
Motherwort's primary bioactive compound leonurine acts on cardiac β-adrenergic receptors, producing negative chronotropic effects that slow heart rate. The herb's flavonoids, particularly rutin and quercetin, contribute to mild vasodilation through nitric oxide pathways. These mechanisms work together to reduce cardiac workload and support healthy blood pressure regulation.
Clinical Narrative (Provisional)
Clinical evidence for motherwort remains limited, with most research consisting of small pilot studies. One study in hypertensive patients with anxiety showed modest blood pressure reductions of 10-15 mmHg systolic after 4 weeks of use. Preclinical studies demonstrate reduced left ventricular pressure and heart rate variability improvements. Larger randomized controlled trials are needed to establish definitive therapeutic benefits and optimal dosing protocols.
