Chinese Motherwort Herb
Chinese Motherwort (Yi Mu Cao): A Blood-Invigorating Herb for Menstrual Health, Circulation, and Postpartum Recovery
Introduction
Chinese motherwort, known as Yi Mu Cao (益母草) in Traditional Chinese Medicine (TCM), is a powerful herb traditionally used to regulate menstruation, invigorate blood circulation, and promote recovery after childbirth. Pungent and slightly bitter with a cooling nature, Yi Mu Cao is particularly valued in gynecological formulas for its ability to move blood without causing excessive loss. Its name means “beneficial to mothers,” reflecting its centuries-old use in women’s health and reproductive recovery.
What Is Chinese Motherwort?
Yi Mu Cao comes from the aerial parts of Leonurus japonicus, harvested during the flowering season. In TCM, it is classified as acrid, bitter, and slightly cold, entering the Heart, Liver, and Bladder meridians. It is traditionally used to invigorate blood, regulate menstruation, promote urination, and clear heat and toxins. Often included in postpartum and menstrual support formulas, this herb helps dispel stasis and restore balance.
