What is Potentilla anserina used for traditionally?

Traditionally, Potentilla anserina (silverweed) has been used in European herbal medicine to relieve mild menstrual cramps (dysmenorrhea) and gastrointestinal spasms. The EMA recognizes this use as a traditional herbal medicinal product based on at least 30 years of documented use, including 15 years within the EU, though not on clinical trial data.

What are the active compounds in Potentilla anserina?

The key bioactive compounds in Potentilla anserina include polysaccharides (PAP), flavonoids such as quercetin and luteolin, ellagitannins, and condensed tannins. These compounds collectively contribute to the plant's antioxidant, anti-inflammatory, and antispasmodic properties observed in laboratory and animal studies.

Does Potentilla anserina help with gut health or ulcerative colitis?

Preclinical mouse studies show that Potentilla anserina flavonoids (PAF) reduced ulcerative colitis symptoms by lowering MDA levels, raising SOD activity, and restoring gut microbiota balance including Firmicutes and Bacteroidetes ratios. These findings are promising but have not yet been replicated in human clinical trials, so conclusions about efficacy in humans remain preliminary.

What is the recommended dosage of Potentilla anserina?

The EMA traditional use monograph specifies a typical adult dose of 4–6 g of dried Potentilla anserina herb per day as a herbal tea infusion, or equivalent preparations standardized to tannin content. No clinically validated dosage exists for isolated polysaccharide or flavonoid extracts, as human dose-finding studies have not been conducted.

Is Potentilla anserina safe to take with other medications?

Potentilla anserina's high tannin content can bind to and reduce absorption of iron supplements, tetracycline antibiotics, and potentially other mineral-based drugs if taken simultaneously; a 2-hour separation is advisable. Its flavonoid constituents may theoretically potentiate anticoagulant effects of warfarin or aspirin, so patients on blood-thinning medications should consult a healthcare provider before use.

What does the research show about Potentilla anserina's anti-inflammatory effects?

Recent animal studies demonstrate that Potentilla anserina (PAP) reduces inflammation through activation of the Rap1 pathway, which suppresses M1 macrophage responses in lung injury models. However, these findings are preliminary and based on mouse studies, so human clinical evidence is still needed to confirm whether similar anti-inflammatory benefits occur in people. Most traditional use supports general inflammatory support, but robust human trials are lacking for specific conditions.

Is Potentilla anserina suitable for people with inflammatory bowel conditions?

Animal research suggests Potentilla anserina may help reduce symptoms of ulcerative colitis by decreasing oxidative stress and restoring healthy microbiota balance in the gut. These promising findings come from laboratory studies in mice with chemically-induced colitis, but clinical evidence in humans with IBD remains limited. Anyone with ulcerative colitis or Crohn's disease should consult their healthcare provider before using Potentilla anserina as a supplement, as it should complement rather than replace standard medical treatment.

How does Potentilla anserina compare to other traditional plants used for gut health?

Potentilla anserina differs from common gut-health plants like slippery elm or marshmallow root by its specific focus on macrophage modulation and microbiota restoration, though direct comparative human studies are unavailable. Its traditional use spans multiple regions (European, Asian) with historical applications for digestive complaints, similar to plantain and meadowsweet. Without head-to-head clinical trials, the relative effectiveness of Potentilla anserina versus other traditionally-used plants for specific gut conditions cannot be definitively established.

Potentilla anserina

Potentilla anserina (silverweed) contains bioactive polysaccharides and polyphenols, including ellagitannins and flavonoids, that exert anti-inflammatory and antioxidant effects. Its primary mechanisms involve modulation of macrophage polarization via the Rap1 signaling pathway and restoration of gut microbiota balance in inflammatory conditions.

Potentilla anserina — Hermetica Encyclopedia

Origin & History

Potentilla anserina L., commonly known as silverweed or anserine cinquefoil, is a perennial herb in the Rosaceae family native to temperate regions including southwestern China. The plant's aerial parts and rhizomes yield bioactive extracts containing polysaccharides (PAP), flavonoids (PAF yielding 2.90±0.07%), and phenolic compounds through high-speed shear extraction and standard solvent extraction methods.

Historical & Cultural Context

Potentilla anserina has been used for centuries in Tibetan, Chinese, and Mongolian traditional medicine as both food and remedy. Tibetan medicine employs it therapeutically, while Mongolian herders apply it as an astringent for enterocolitis and dyspepsia, and Chinese medicine uses the whole plant for various conditions including hematemesis and as a cardioprotective agent.

Health Benefits

• Anti-inflammatory effects: PAP reduced inflammation and M1 macrophage response in mouse lung injury models via Rap1 pathway activation (preliminary animal evidence, PMID: 39922353)
• Gut health support: PAF improved ulcerative colitis symptoms, reduced oxidative stress, and restored microbiota balance in DSS-induced colitis mice (preliminary animal evidence, PMID: 40636944)
• Insulin sensitivity: Phenolic compounds enhanced glucose uptake via Akt phosphorylation and reduced oxidative stress in insulin-resistant adipocytes (preliminary in vitro evidence, PMID: 36717756)
• Skin barrier function: Topical extract improved hydration and reduced itch mediator expression in a 4-week human trial (n=33), though effects were comparable to control moisturizers (limited clinical evidence)
• Antioxidant activity: Multiple extracts demonstrated ROS reduction and mitochondrial protection across various cell models (preliminary in vitro evidence)

How It Works

Potentilla anserina polysaccharides (PAP) activate the Rap1 signaling pathway, suppressing M1 macrophage polarization and reducing pro-inflammatory cytokine release in lung tissue. Potentilla anserina flavonoids inhibit NF-κB transcription factor activity, lowering oxidative stress markers including malondialdehyde (MDA) while upregulating superoxide dismutase (SOD). The plant's ellagitannins and tannin complexes also inhibit cyclooxygenase (COX) enzymes, contributing to its classical anti-inflammatory and antispasmodic activity recognized in EMA traditional use guidelines.

Scientific Research

Clinical evidence for Potentilla anserina is limited to one small topical trial (n=33) showing skin hydration improvements over 4 weeks. Most research consists of preclinical studies including PAP in LPS-induced lung injury models (PMID: 39922353), PAF in ulcerative colitis mice (PMID: 40636944), and phenolic compounds in insulin-resistant adipocytes (PMID: 36717756).

Clinical Summary

Current evidence for Potentilla anserina is predominantly preclinical; animal models of acute lung injury demonstrate PAP significantly reduced inflammatory infiltration and cytokine levels via Rap1 pathway activation (PMID: 39922353). Potentilla anserina flavonoids (PAF) improved ulcerative colitis outcomes in murine models, reducing oxidative stress biomarkers and restoring Firmicutes/Bacteroidetes microbiota ratios. The EMA has granted traditional herbal medicinal product (THMP) status based on longstanding European use for mild menstrual cramps and gastrointestinal spasms, not on controlled clinical trials. Robust randomized controlled trials in human populations are currently lacking, meaning all mechanistic findings should be interpreted as preliminary.

Nutritional Profile

Potentilla anserina (silverweed) contains a range of documented bioactive compounds and nutrients. Polysaccharides (PAP/PAF) are primary bioactive constituents, estimated at 5–15% dry weight depending on plant part and extraction method. Flavonoids are well-represented, including quercetin, kaempferol, and luteolin glycosides, collectively estimated at 1–3% dry weight; these contribute to antioxidant and anti-inflammatory activity with moderate oral bioavailability enhanced by gut microbial deglycosylation. Tannins (ellagitannins and condensed tannins, primarily tormentillin and agrimoniin-type compounds) are present at approximately 5–10% dry weight in aerial parts, contributing astringent and antimicrobial properties but potentially reducing mineral bioavailability. Phenolic acids include chlorogenic acid, caffeic acid, and ellagic acid at trace-to-moderate levels (~0.5–2% dry weight). The roots and rhizomes contain starch at relatively high concentrations (~20–30% dry weight), historically used as a food source; protein content in aerial parts is modest (~8–12% dry weight on a dry basis). Mineral content includes potassium (~300–500 mg/100g dry), calcium (~200–400 mg/100g dry), and iron (~5–15 mg/100g dry), though tannin co-presence may reduce iron and zinc bioavailability. Vitamin C has been reported in fresh aerial parts at low-to-moderate levels (~20–50 mg/100g fresh weight). Dietary fiber is substantial in whole plant preparations (~15–25% dry weight), contributing to the gut microbiota-modulatory effects observed in colitis models. Triterpenoids (ursolic acid, oleanolic acid, tormentic acid) are present in smaller quantities (~0.2–1% dry weight) and contribute to anti-inflammatory bioactivity. Bioavailability of polysaccharide fractions (PAP, PAF) is primarily through gut-mediated immune modulation rather than systemic absorption, consistent with their demonstrated effects on colitis and macrophage pathways in animal models.

Preparation & Dosage

Synergy & Pairings

Turmeric, Boswellia serrata, Quercetin, Probiotics, Green tea extract

Safety & Interactions

Potentilla anserina is generally well-tolerated at traditional doses, with no serious adverse events documented in EMA monograph review, though mild gastrointestinal upset is possible. Due to its high tannin content, it may reduce the absorption of iron supplements and certain antibiotics such as tetracyclines if taken concurrently. Anticoagulant drug interactions are theoretically possible given its flavonoid content, warranting caution in patients on warfarin or antiplatelet therapy. Safety during pregnancy and lactation has not been established in clinical studies, and the EMA advises against use in these populations due to insufficient data.
