Contemporary medical herbalists believe that silverweed‘s main medicinal value lies in its astringency although it has been throughout the ages as a medicinal herb for other purposes. It is less astringent than the related P. erecta, but it has a gentler action within the gastro-intestinal tract. The whole plant is antispasmodic, mildly astringent, diuretic, foot care, haemostatic, odontalgic and tonic. A strong infusion is used to check the bleeding of piles and to treat diarrhoea, it is also used as a gargle for sore throats. Externally, it is used as a powder to treat ulcers and haemorrhoids whilst the whole bruised plant, placed over a painful area, will act as a local analgesic. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Potentilla anserina Silverweed for diarrhoea, inflammation of the mouth and pharynx, premenstrual syndrome.
Description of Silverweed:
Potentilla anserina; Silverweed is a PERENNIAL growing to 0.3 m (1ft) by 1 m (3ft 3in) at a fast rate.
It is hardy to zone 5 and is not frost tender. It is in flower from Jun to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies, beetles, self.The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil. The plant can tolerate maritime exposure.
Cultivation of Silverweed:
A very easily grown plant, succeeding in almost any soil, thriving in moist clays, though rather dwarfed in dry dusty soils. It grows best in a well-drained loam, preferring a position in full sun but tolerating shade. Prefers an alkaline soil but tolerates a slightly acid soil. Silverweed was formerly cultivated for its edible root. It is still possibly cultivated in parts of Scotland (1992). This plant spreads vigorously by its running roots and can be very invasive. It grows well in a meadow, or places where the grass is only cut occasionally. Members of this genus are rarely if ever troubled by browsing deer.
Collection of Silverweed:
The roots are the most astringent part of the plant, they are harvested in late summer or autumn and dried for later use. The leaves are harvested in early summer and dried for later use.
Propagation of Silverweed:
Seed – sow early spring or autumn in a cold frame. Prick out the seedlings into individual pots once they are large enough to handle and plant them out into their permanent positions in the summer. Division in spring. Division is also very easy at almost any time the plant is in growth. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
Culinary uses of Silverweed:
Edible Parts: Leaves, Root.
Edible Uses: Tea.
Root – raw or cooked. It can also be dried and ground into a powder then used in soups etc or mixed with cereals. A nice taste, crisp and nutty with a somewhat starchy flavour.
