Knotgrass
Polygonum aviculare L.

Family: Polygonaceae.

Other Names: Knotweed; renouée des oiseaux (French); Vogelknöterich (German); centinodia (Italian).

Description: A spreading, wiry annual weed with sparse, slender stems, distinct nodes covered by translucent stipular sheaths (these have lacerated edges and are dark-coloured at their bases, giving the sterns a distinctive "knotty" appearance) and small, narrow, almost stalkless leaves. Minute reddish flowers are borne in the leaf axils. Several Polygonum species have been moved to the genus Persicaria. Roots of flowery knotweed or he shou wu (Polygonum multiflorum or Fallopia multiflora) is important in Chinese health.

Origin: Europe and Asia; it has become a weed of cultivation in all temperate parts of the world and is collected mainly in eastern Europe.

Parts Used: Whole herb, including the roots (knotweed herb - Polygoni avicularis herba).

Therapeutic Category: Traditional expectorant.

Uses and Properties: Knotweed herb is mainly used, to this day, to help support coughs, bronchial catarrh and inflammation of the mouth and upper respiratory tract. In China and the eastern Mediterranean region it has been used since ancient times as a diuretic and in traditional health also for throat and bronchial ailments, as haemostyptic and to help support skin problems. He shou wu is a tonic herb used in China for numerous and diverse indications (including liver ailments, kidney problems, nervous complaints, premature ageing and infertility).

Preparation and Dosage: A cup of tea can be made from 1.5 g of the chopped dry herb, and taken three to five times a day for coughs and catarrh. The herb or extracts thereof form ingredients of cough teas and various proprietary products used as antitussive and diuretic medicines.

Active Ingredients: It has been speculated that the tannins (3.6% gallo- and catechol tannins) are the main active compounds. Other potentially active constituents present are flavonoids (such as avicularin, quercetin 3-arabinoside, hyperoside, vitexin), mucilage, siicic acid (1%), phenolcarboxylic acids and some coumarins.

Health Effects: Tannins unspecifically inhibit enzymes and receptors; it is plausible to attribute anti-inflammatory and haemostyptic properties to tannins and other phenolic compounds. Silicic acid and flavonoids might enhance diuresis.

Status: Traditional health; Comm. E+.
