Moneywort (Lysimachia nummularia): Prostate Health, Urinary Benefits, Ingestion, and Scientific Overview
Moneywort (Lysimachia nummularia) is a creeping perennial herb native to Europe and Western Asia, now naturalized in North America and other regions. Sometimes called “creeping jenny” or “herb twopence,” Moneywort is recognized for its round, coin-like leaves and bright yellow flowers. While primarily valued as an ornamental groundcover, the plant has a long-standing place in traditional medicine, especially in European and Asian herbal systems.
Botanical Description and Active Constituents
Moneywort belongs to the Primulaceae family. Traditionally, the whole plant is used, though above-ground parts are more common in remedies. Key bioactive compounds include:
- Saponins
- Flavonoids (quercetin, kaempferol)
- Triterpenoids
- Phenolic acids
- Tannins
These constituents contribute to its anti-inflammatory, diuretic, and antimicrobial properties.
Traditional Uses in Herbal Medicine
Historical Applications
Historically, Moneywort has been used to:
- Treat wounds and skin inflammation
- Soothe coughs and sore throats
- Support liver and gallbladder function
- Relieve mild diarrhea
- Promote urination and address fluid retention
Use in Modern Herbalism
Contemporary herbalists employ Moneywort primarily as a mild diuretic, anti-inflammatory, and tonic for the urinary system. It is sometimes included in formulas aimed at supporting prostate and urinary tract health, particularly for men experiencing lower urinary tract symptoms (LUTS).
Effects on Men’s Health and Prostate Function
1. Anti-inflammatory Effects
Moneywort’s anti-inflammatory phytochemicals may reduce swelling and discomfort in the urinary tract and prostate. This is particularly relevant for men with:
- Benign prostatic hyperplasia (BPH)
- Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)
- Lower urinary tract symptoms (LUTS)
Mechanism:
Flavonoids and triterpenoids help modulate inflammatory pathways, potentially easing symptoms such as pelvic pain, frequent urination, and incomplete bladder emptying.
2. Diuretic Properties
Moneywort has been used as a mild diuretic, supporting increased urine output and flow. This can be beneficial for men who:
- Experience urinary retention due to prostate enlargement
- Suffer from urinary tract discomfort or mild infections
Caution:
As with all diuretics, excessive use can lead to electrolyte imbalances if not monitored.
3. Antimicrobial Action
The plant’s saponins and phenolics possess some antibacterial activity, which can help reduce urinary tract infections—a secondary concern in men with BPH or frequent catheterization.
4. Bladder Health and Irritation Relief
Traditional texts recommend Moneywort for easing bladder irritation and mild inflammation, which may indirectly support men dealing with urinary urgency and frequency associated with prostate issues.
5. Miscellaneous Men’s Health Benefits
- Wound healing: Used topically for minor wounds and inflammation.
- Antioxidant effects: Flavonoids may offer systemic antioxidant support, reducing oxidative stress in the genitourinary tract.
Clinical Evidence and Limitations
Modern scientific evidence for Moneywort’s specific effects on prostate health is limited. Most data are from in vitro studies, animal models, or extrapolated from closely related Lysimachia species. However, its pharmacological actions support its traditional use for urinary complaints and inflammation.
No large-scale clinical trials directly evaluating Moneywort for BPH or prostate health exist as of 2025, but its safety and utility as a supportive herb are generally recognized in European phytotherapy.
Ingestion Methods
1. Herbal Tea (Infusion)
- Preparation: 1–2 teaspoons dried Moneywort per cup of boiling water. Steep 10–15 minutes. Strain and drink.
- Usage: 1–3 cups per day, often blended with other urinary tract-supporting herbs.
2. Tincture (Alcohol Extract)
- Preparation: Commercially available or homemade (1:5 ratio, 25% alcohol).
- Dosage: Typically 2–4 ml, up to three times daily, diluted in water.
3. Capsules or Powder
- Less common. Standardized dosages are rare; always follow manufacturer instructions.
4. Topical Use
- Fresh or dried Moneywort can be used in poultices or washes for skin issues, but this is not relevant to prostate health.
Note:
Consultation with a healthcare provider is advised, particularly for men taking diuretics, anticoagulants, or those with chronic kidney conditions.
Safety, Contraindications, and Interactions
- Generally safe in moderate doses when used as a tea or tincture.
- Possible side effects: Nausea or mild gastrointestinal upset in sensitive individuals.
- Avoid in pregnancy and lactation due to lack of safety data.
- Potential interactions: May potentiate the effects of pharmaceutical diuretics or blood thinners.
Additional Data and Emerging Research
- Synergy with other herbs: Moneywort is often combined with saw palmetto, nettle root, or pumpkin seed for enhanced prostate support.
- Research opportunities: More investigation is needed into its specific action on human prostate cells and urinary function.
