Chinese Motherwort
Also known as: Leonurus cardiaca, Leonurus japonicus, Motherwort, Lion's Tail, Chinese Motherwort, European Motherwort
Overview
Motherwort, scientifically known as *Leonurus cardiaca* (European) and *Leonurus japonicus* (Chinese), is a perennial herb native to Asia and Southeastern Europe. It has a long history of traditional use in both Chinese and European herbal medicine, primarily for its purported benefits related to anxiety, heart health, menstrual disorders, and postpartum hemorrhage prevention. The herb contains various bioactive compounds, including flavonoids, hydroxycinnamic acids, and iridoids, which are believed to contribute to its therapeutic effects. While motherwort is available in several forms, such as loose-leaf tea, tinctures, and capsules, it's important to note that the scientific evidence supporting its traditional uses is limited, and most studies have methodological limitations. Therefore, further high-quality research is needed to validate its efficacy and safety.
Benefits
The primary evidence-based benefit of motherwort lies in postpartum hemorrhage prevention. A systematic review suggests that motherwort injection combined with oxytocin may reduce postpartum blood loss compared to oxytocin alone. However, the quality of evidence is low. Preliminary animal studies also indicate potential benefits in reducing symptoms of anxiety and depression, though these findings require confirmation in human trials. While motherwort is traditionally used for heart health and menstrual disorders, the evidence supporting these uses is currently limited. Therefore, its use should be approached with caution, and under the guidance of a healthcare professional.
How it works
Motherwort's mechanism of action involves multiple biological pathways. Network pharmacology analysis suggests that it interacts with targets such as AKT1, PTGS2, ESR1, AR, and PPARG, influencing endocrine, vascular, and anti-inflammatory processes. These interactions may affect the cardiovascular and nervous systems. Bioactive compounds in motherwort are believed to bind to various genes, potentially regulating biological functions. However, the absorption and bioavailability of these compounds are not well-studied, and further research is needed to fully elucidate the herb's mechanism of action.
Side effects
Limited evidence exists regarding the overall safety of motherwort. Common side effects may include diarrhea and stomach pain. Uncommon side effects include uterine bleeding. Due to the potential for uterine stimulation, motherwort is contraindicated during pregnancy and breastfeeding. It may also interact with heart medications, so individuals taking such medications should avoid its use. It is essential to consult with a healthcare professional before using motherwort, especially if pregnant, breastfeeding, or taking other medications. The European Medicines Agency suggests consuming less than 3 grams of powdered extract per day to minimize side effects.
Dosage
There is no established minimum effective dose or maximum safe dose for motherwort. The European Medicines Agency suggests consuming less than 3 grams of powdered extract per day to minimize side effects. Motherwort is available in various forms, including loose-leaf tea, tincture, and capsules. However, there are no specific timing recommendations or form-specific dosage guidelines. Due to the limited research on its safety and efficacy, it is crucial to consult with a healthcare professional before using motherwort to determine an appropriate dosage and ensure its safe use.
FAQs

Yes, motherwort may interact with heart medications. It is crucial to consult with a healthcare professional before use, especially if you are taking any medications.
What are the potential side effects of motherwort?
Common side effects may include diarrhea and stomach pain. Uncommon side effects include uterine bleeding. Consult a healthcare professional if you experience any adverse effects.
How much motherwort should I take?
There is no established recommended dosage. The European Medicines Agency suggests consuming less than 3 grams of powdered extract per day to minimize side effects. Consult a healthcare professional for personalized advice.
What is motherwort traditionally used for?
Motherwort is traditionally used for anxiety, heart health, menstrual disorders, and postpartum hemorrhage prevention, but scientific evidence supporting these uses is limited.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/31354850/ – A systematic review and meta-analysis (37 RCTs, n=7887) found that motherwort injection combined with oxytocin may reduce postpartum blood loss compared to oxytocin alone. However, the authors noted that the quality of the evidence was low, suggesting the need for further rigorous studies to confirm these findings.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7911030/ – This study performed a phytochemical analysis and identified flavonoids, hydroxycinnamic acids, and iridoids in motherwort extracts. These compounds suggest potential psychotropic effects, which could contribute to the herb's traditional use for anxiety and mood disorders, though further research is needed to confirm these effects.
