Motherwort Leonurus cardiaca

Botanical Information

Common Names: Motherwort

Folk Names: Lion’s Tail, Lionheart, Throw-wort

Botanical Name: Leonurus cardiaca

Family: Lamiaceae (Mint family)

Description: Perennial mint-family herb with square stems, deeply lobed leaves, and whorls of small pink to pale purple flowers around the stem. Slightly hairy and strongly bitter-aromatic, reaching 2–4 feet in height.

History & Tradition

• Traditional European herb for “mothers”—used postpartum, for menstrual regulation, and for nervous agitation around reproductive transitions.
• Known as a “heart” herb both physically and emotionally, easing palpitations associated with anxiety.
• Called Lionheart, referencing courage, strength, and heart steadiness.
• Used as a bitter tonic and mild sedative in cases of nervous tension, especially where the heart and womb are involved.

Motherwort tends both the womb and the heart, offering a firm but loving presence during times of stress, transition, and emotional upheaval.

Notes from Mrs. M. Grieve: Motherwort is cited as a valuable women’s herb, an emmenagogue, and a tonic for both the heart and the nervous system, particularly useful in hysterical or nervous disorders.
