Lamiaceae · herb
Motherwort
Leonurus cardiaca
Aerial parts mapped as a traditional 'womb' nervine and later mild cardiac folklore.
Safety first
Pregnancy avoid. Cardiac-glycoside-like caution is often overstated for L. cardiaca but the plant is still not a heart-failure tea. Yi mu cao (L. japonicus) is a related, not identical, TCM herb.
Tradition vs trials
Traditional record. European motherwort; TCM yi mu cao is Leonurus japonicus — listed so the names are not collapsed.
Trial literature. Human files are thin. This catalog tags traditional.
