Drug Interactions: Motherwort lowers blood pressure slightly so it may interact with blood pressure medications. Because of its nervine effects, it may also synergize with anxiolytic or opiate based pain medications.
- Tincture: (extracted fresh in 60% alcohol) take ½ to 1 teaspoon up to twice a day.
- Infusion: use 1-2 teaspoons of dried herb per cup of boiling water. Steep 10 minutes. Drink up to 2 cups a day. Because of the very bitter taste, add honey or other sweetener.
Combinations: as a heart tonic can be combined with hawthorn and linden, for hotflashes combined with blue vervain and black cohosh, for fevers combined with boneset, yarrow, or blue vervain.
Energetics: Cooling, drying
Folklore: In ancient China, motherwort was reputed to promote longevity. In Europe, Motherwort first became known as a treatment for cattle diseases. Colonists introduced Motherwort into North America and the 19 th century Eclectics recommended it as a menstruation promoter and aid to expelling the afterbirth. Ritual Uses: herb of Venus and Leo.

Phytochemistry and pharmacology of the genus Leonurus: The herb to benefit the mothers and more.
Plants belonging to the genus Leonurus, also named Motherwort, are traditionally used for anti-gynecological disorder in East Asia, and for sedative in Europe. Chemical investigation of the genus Leonurus not only enriched the natural products library, but also enlarged the pharmacological application of this traditional herb. In this review, we systematically summarized the structures of 259 compounds isolated from the genus Leonurus, featured with 147 labdane diterpenoids. The reported bioactivity studies up to 2017 are presented in the second part, with the main focus on the isolated compounds and also concerning the extracts. In addition to the traditional uterine contraction and sedative activity, recently the cardiovascular protection effect of leonurine has drawn most attention. Other than that, neuroprotection, anti-inflammation, anti-cancer, anti-platelet aggregation and many other activities have been assigned to various compounds from the genus Leonurus. Among 70 bioactivity references cited in this review, 57% of them were concentrated on two alkaloids (leonurine and stachydrine), whereas only 20% are about the 147 diterpenoids. Anti-inflammation is the major bioactivity discovered so far for the labdane diterpenoids from the genus Leonurus, whose further therapeutic potential still remains for exploration.

Leonurus cardiaca L. (motherwort): a review of its phytochemistry and pharmacology.
Leonurus cardiaca is a perennial plant indigenous to central Europe and Scandinavia, but it is also found in the area spanning temperate Russia to central Asia. It has been introduced to North America and has become established locally in the wild. Motherwort (Leonuri cardiacae herba) consists of aerial parts of Leonurus cardiaca gathered during the flowering period, dried at 35 °C and, according to European Pharmacopoeia 7th edition, should contain a minimum of 0.2% flavonoids, expressed as hyperoside. Compounds belonging to the group of monoterpenes, diterpenes, triterpenes, nitrogen- containing compounds, phenylpropanoids, flavonoids and phenolic acids, as well as volatile oils, sterols and tannins, have been identified in motherwort. Traditionally, extracts of the herb have been used internally, mainly for nervous heart conditions and digestive disorders. However, they have also been used for bronchial asthma, climacteric symptoms and amenorrhoea, as well as externally in wounds and skin inflammations. Mild negative chronotropic, hypotonic and sedative effects can be attributed to the herb and preparations thereof. Pharmacological studies have confirmed its antibacterial, antioxidant, anti-inflammatory and analgesic activity, as well as its effects on the heart and the circulatory system. Sedative and hypotensive activity has been demonstrated in clinical trials.
