Argentina anserina
Gemeines Gänsefingerkraut · (Potentilla anserina)
Rose family (Rosaceae)
Description
Silverweed creeps across path edges, riverbanks and grazed ground on long, rooting runners. It is recognised by its pinnate leaves, whose undersides shine silver from dense hairs — the source of its English name — together with solitary yellow flowers from May to August. The flowering herb is the part used. Its high tannin content acts astringently on mucous membranes, and the German Commission E has recognised three applications on that basis: as a tea for mild, acute diarrhoea, for mild menstrual pain, and as a gargle for inflammation of the mouth and throat. Animal studies show increased tone in the uterine muscle, which may explain the second use, though the evidence for it is weaker than for the first. In sensitive stomachs the tannins can irritate, so the herb is not suited to long-term daily drinking.
Infusion of the herb for mild, acute diarrhoea. The German Commission E recognised this indication for Potentillae anserinae herba. The astringent effect is due to the tannin content.
Preparation & dosage
Pour 250 ml boiling water over 2 g dried herb, steep 10 min, strain. Total daily amount 4–6 g crude drug.
- Dry amount
- 4–6 g
- Doses per day
- 3×
For mild dysmenorrhoea (menstrual pain), the use of silverweed herb is recognised by the German Commission E. Animal studies show uterine muscle tone- and contraction-enhancing effects.
Preparation & dosage
- Dry amount
- 4–6 g
- Doses per day
- 3×
Gargling with a more concentrated infusion for mild inflammation of the oral and pharyngeal mucosa, also recognised by the German Commission E for Potentillae anserinae herba.
Preparation & dosage
The root contains higher tannin levels than the aerial herb and was traditionally used in stronger infusions for diarrhoea and bleeding. The root is considered the most tannin-rich plant part.
Preparation & dosage
- Dry amount
- 2–4 g
- Doses per day
- 2×
Bruised or powdered herb was applied as a compress for ulcers and wounds. Folk medicine also used it as a local pain remedy for dental and joint complaints.
The carbohydrate-rich roots were used as a food source in various cultures (North America, Tibet) and resemble parsnip in taste. They were especially harvested in spring and autumn.
The tannin content may cause stomach irritation in sensitive individuals. The antispasmodic effect in dysmenorrhoea is less well-evidenced than the antidiarrhoeal effect. Do not use as monotherapy for severe cramps. ASPCA classification (accessed 2026-08-10): non-toxic to dogs and cats. The ASPCA classifies the whole genus this way.
Avoid in pregnancy due to uterus-stimulating effects shown in animal studies.
Insufficient data available; avoid as a precaution.
Not recommended for children under 12 years, as no clinical data are available.
