Classical Discussions on Motherwort
1. From Ben Cao Gang Mu (Compendium of Materia Medica): "The root, stem, flower, leaf, and seed of Motherwort are all used in medicine and can be combined. For wind-heat in the blood aspect of the Hand and Foot Jueyin meridians (Pericardium and Liver), improving vision, benefiting essence, and regulating women's meridians, using only the seeds (Chong Wei Zi) is excellent. For treating swellings and sores, resolving water retention, moving blood, and addressing various gynecological and obstetric conditions, using all parts together is beneficial. This is because the root, stem, flower, and leaf primarily promote circulation, while the seeds have a concurrent action of moving and nourishing." This emphasizes Motherwort's comprehensive utility in gynecological disorders (PMID: 35115206).
2. From Ben Cao Qiu Zhen (Materia Medica Seeking Truth): "Motherwort (specifically enters the Heart Pericardium and Liver). Also known as Chong Wei. It is pungent, slightly bitter, and cold. Its function is to enter the Liver and Pericardium meridians, resolving water retention, moving blood, dispelling stagnation to generate new blood, regulating menstruation, and detoxifying." This highlights its core actions within specific meridian systems.
3. From Ben Cao Bei Yao (Essentials of Materia Medica): "It effectively moves stagnant blood and generates new blood. It is pungent, slightly bitter, and cold. It enters the Hand and Foot Jueyin meridians (Heart Pericardium and Liver). It resolves water retention, moves blood, dispels stagnation to generate new blood, regulates menstruation, and detoxifies." This reinforces the herb's primary actions in managing blood stasis and promoting circulation, a key aspect of TCM gynecology (PMID: 30129871).
