“There is no better herb to take melancholy vapours from the heart, to strengthen it, and make a merry, chearful blithe soul than this herb. ”
Chinese motherwort, known as yi-mu-cao, and the common European motherwort serve as excellent examples of plants used for parallel purposes by divergent cultures, whose uses are confirmed by modern research. This fascinating but still little-appreciated member of the mint family deserves greater attention in the West. In TCM motherwort was used to promote longevity and strengthen the heart, just as western herbal medicine considers motherwort to be one of the best heart tonics. Motherwort is used to promote blood circulation, lower cholesterol, slow a too rapid heart rate, and relieve stress on the heart muscle. (Duke,James, Ph.D.) It also is diuretic, and reduces swelling, helping to lower blood pressure. These medicinal actions are confirmed by science to be linked to the bitter glycosides as well as other phytochemicals that motherwort contains. (Foster, Steven and Yue "Herbal Emissaries") Motherwort ia approved for use in nervous cardiac disorders and as adjuvant for thyroid hyperfunction by the German Commision E. Commission E Monographs
Motherwort is also one of the best tonic
herbs for women. Motherwort is especially valuable in a wide range of
female disorders (hence the name), allaying nervous irritability and inducing
quiet and passivity of the whole nervous system. I find motherwort a good
remedy for those times when you feel a generalized anxiety without
any clear cut cause. The herb regulates the menses, and is a strong emmenagogue,
helping to stimulate delayed periods and is an excellent remedy for menstrual
cramps especially those accompanied by scanty
menses. The combination of motherwort with scullcap and/or valerian can help to relieve pain and stress associated with childbirth. (Gladstar, Rosemary)
Preparation Methods & Dosage :Motherwort is available in capsule and extract form, but is most useful taken as a tea. The somewhat bitter taste can be mellowed by adding spices or sweeter tasting herbs. Frequently combined with hawthorn for heart tonics.

Li Shi-zhen lists the uses of the seeds and herb in the 1596 Ben Cao Gang Mu. He noted that it helped to stimulate circulation, benefit the eyes, quiet the nerves, and regulate the menses, among other uses.
