Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Leonurine and related iridoid/alkaloid-type constituents are considered the principal cardioactive and uterotonic compounds.
Antioxidant constituents contributing to the plant's anti-inflammatory activity.
Bitter diterpenes, shared with related Lamiaceae bitters, contributing to the traditional digestive and cardiac reputation.

Safety, Cautions & Contraindications
Contraindicated in pregnancy (uterine stimulant). Avoid in heavy menstrual bleeding. May enhance anticoagulant and antihypertensive drug effects. Avoid in thyroid disorders. Generally well tolerated in normal doses for short-term use.
Duke (2002) rates motherwort as ++ and notes hypotensive, cardiotonic (negative chronotropic), anti-aggregant, and sedative activities at the experimental level (score 1). The plant is traditionally used for heart palpitations, hypertension, and menstrual regulation in European herbalism. Duke emphasizes strong safety caution: motherwort has documented oxytocic (uterine-stimulating) activity and is strictly contraindicated in pregnancy. It may also enhance the effects of cardiac medications and sedatives (Duke, 2002).
Allergy risk: avoid if you’re allergic to cowslip/other Primula species (European Medicines Agency, 2012). Stomach sensitivity: use caution if you have gastritis or a stomach ulcer—cowslip can upset the stomach in some people (European Medicines Agency, 2012). Possible side effects (especially high dose): nausea, vomiting, diarrhea; allergic reactions can happen (European Medicines Agency, 2012). Pregnancy/breastfeeding: not recommended due to lack of good safety data (European Medicines Agency, 2012). Kids: many preparations are not recommended under 12 (and some root extracts under 4) unless a labeled product specifically allows it (European Medicines Agency, 2012).
Duke (2002) provides clinical evidence (score 2) for cowslip's expectorant and secretolytic activities, consistent with Commission E approval for bronchitis and cough with mucus. Dose: 0.5–1 g root or 1–2 g herb as tea three times daily. Saponins in the root are responsible for the expectorant action. Duke warns that the plant may cause hemolysis in large doses due to saponin content, and caution is warranted in individuals with aspirin sensitivity due to phenolic acid content (Duke, 2002).

Botanical Description
Tall, upright perennial herb with deeply palmately lobed lower leaves (giving a lion's-paw appearance, the source of the genus name) and progressively less-divided upper leaves. Small, pink to pale purple, spiny-toothed, two-lipped flowers are borne in dense whorls up the square stem.[1]
Low perennial herb (Primulaceae) forming a basal rosette of wrinkled, oval, softly hairy leaves that taper abruptly to a winged stalk. A single leafless flowering stem rises from the rosette bearing a one-sided umbel of small, fragrant, deep yellow, funnel-shaped flowers with orange spots at the throat, nodding on slender pedicels.[10]
Habitat
Grows on waste ground, roadsides, hedgerows and near old dwellings; native to Central Asia and southeastern Europe and long naturalised across Europe and North America.[1]
Native across Europe and western Asia, growing in unimproved, species-rich grassland, meadows, pastures, open woodland and hedge banks on calcareous or well-drained soils.[10]
Harvesting
The flowering aerial parts (leaf, stem and flower) are cut in summer as the plant comes into flower, and dried in a warm, shaded, airy place.[1]
Flowers are picked in spring as they open; the root/rhizome is dug in autumn.
Traditional Uses
Motherwort has a long European and Asian herbal tradition, reflected in its name, as a gynaecological and cardiac tonic, traditionally used for heart palpitations and nervous cardiac complaints, menstrual irregularities and cramps, and as a calming nervine for anxiety and to ease childbirth and postpartum recovery.[1, 6]
Cowslip has a long European folk tradition as an expectorant remedy for coughs and bronchial catarrh, and the flowers have traditionally been used as a mild sedative and for headache. Modern research on its saponin-rich root supports secretolytic (mucus-thinning) expectorant activity, and its flowers are rich in antioxidant phenolics.[1, 6]
Preparations
Dosage
The EU herbal monograph gives a single dose of 1.5-4.5 g of the comminuted herb for tea preparation, for a daily dose of 3-10 g, in adults and elderly; a 1:5 tincture in 45% V/V ethanol at 2-6 mL three times daily and a liquid extract at 2-4 mL three times daily are also listed. If symptoms persist longer than 4 weeks a healthcare practitioner should be consulted. Not recommended under 18 years. Educational reference only, not a prescription.
