Highlander bird (Polygonum aviculare L.)An annual herbaceous plant of the buckwheat family (Polygonaceae), with recumbent or ascending, strongly branching stems up to 60 cm long (the total length of branches of all orders of a well-developed plant reaches 100 m). Taproot, slightly branched. The leaves are alternate, small, short-petiolate, broadly elliptical, grayish-green. The flowers are very small, 2-5 in the axils of the leaves, pale green, white or pink at the edges. The fruit is a triangular, black, rarely brown, matte nutlet. It blooms from May to autumn, the fruits ripen from June to late autumn. Propagated exclusively by seeds. Distributed almost throughout the CIS from the southern borders to the Kola Peninsula in the north. Usually abundant in the middle zone of the European part of the CIS and in the south of Western Siberia, in the forest and steppe zones. Grows along roadsides, near dwellings, in wastelands, pastures, often forms continuous thickets on compacted soils. The plant is resistant to trampling. Grows well after repeated mowing. It is very unpretentious, due to which it is common on all continents, with the exception of Antarctica. In East Slavic mythology, knotweed is a symbol of fertility.


For medicinal purposes, the grass of the highlander is used, which is harvested during the flowering period of the plant, when the stems have not yet had time to harden. When collecting raw materials, leafy shoots up to 30 cm long are cut with a knife or sickle (in dry weather). It is not recommended to collect on grazing areas and within dwellings, in heavily polluted places. Dry in attics with good ventilation, under sheds or in the open air in the shade, spreading out in a thin layer. Its reserves in nature are large. Harvesting of raw materials can be carried out at the same place every year. However, for successful renewal, it will be necessary to leave for seeding within 25% of well-developed plants. The shelf life of raw materials is 3 years. The smell of dry raw materials is weak, the taste is a little tart.


Galenic forms prepared from the plant increase diuresis, excrete excess sodium and chloride ions in the urine, as a result of which filtration in the renal glomeruli increases and reverse resorption in the renal tubules decreases. Knotweed grass prevents the formation of urinary stones, which is associated with the content of soluble silicic acid compounds in herbal products of the plant, which are removed in urine in fairly significant concentrations. Herbal products of the plant have a positive effect on the function of the gastrointestinal tract due to tannins that have antimicrobial, anti-inflammatory and astringent properties. Flavonoids, silicon compounds and tannins of highlander reduce the permeability of the walls of blood vessels, increase blood clotting. In addition, it increases the contractility of smooth muscle organs, mainly by increasing uterine contractions. Plant preparations have insignificant hypotensive properties, deepen breathing, and have low toxicity.
