Botanical Name: Polyganum aviculare
Family: Polygonaceae
Genus: Polygonum
Species: P. aviculare
Kingdom: Plantae
Order: Caryophyllales

Synonyms: Knotgrass. Centinode. Ninety-knot. Nine-joints. Allseed. Bird’s Tongue. Sparrow Tongue. Red Robin. Armstrong. Cowgrass. Hogweed. Pigweed. Pigrush. Swynel Grass. Swine’s Grass.

Common Names : Knotweed, Prostrate knotweed, Birdweed, Pigweed and lowgrass.

Part Used: Whole herb.

Habitat: Polyganum aviculare occurs throughout the world. It is mostly found in fields and wasteland.

Description:
Common knotgrass is an annual herb with a semi-erect stem that may grow to 10 to 40 cm (4 to 16 in) high. The leaves are hairless and short-stalked. They are longish-elliptical with short stalks and rounded bases; the upper ones are few and are linear and stalkless. The stipules are fused into a stem-enclosing, translucent sheath known as an ochrea that is membranous and silvery. The flowers are regular, green with white or pink margins. Each has five perianth segments, overlapping at the base, five to eight stamens and three fused carpels. The fruit is a dark brown, three-edged nut. The seeds need light to germinate which is why this plant appears in disturbed soil in locations where its seeds may have lain dormant for years. It is noted for attracting wildlife……..CLICK & SEE THE PICTURES

Cultivation :
Succeeds in an ordinary garden soil but prefers a moisture retentive not too fertile soil in sun or part shade. Repays generous treatment, in good soils the plant will cover an area up to a metre in diameter. Prefers an acid soil. Dislikes shade. Knotweed is a common and invasive weed of cultivated ground. It is an important food plant for the caterpillars of many species of butterflies. It also produces an abundance of seeds and these are a favourite food for many species of birds. Plants seem to be immune to the predations of rabbits. The flowers have little or no scent or honey and are rarely visited by pollinating insects. Self-fertilization is the usual method of reproduction, though cross-fertilization by insects does sometimes occur. The plant also produces cleistogomous flowers – these never open and therefore are always self-fertilized. The plant is very variable and is seen by most botanists as an aggregate species of 4 very variable species, viz. – P. aviculare. L.; P. boreale. (Lange.)Small.; P. rurivacum. Jord. ex Box.; and P. arenastrum. Box.

Propagation:
Seed – sow spring in a cold frame. Germination is usually free and easy. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer if they have reached sufficient size. If not, overwinter them in a cold frame and plant them out the following spring after the last expected frosts. Division in spring or autumn. Very easy, 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.
Edible Uses :
Edible Parts: Leaves; Seed.
Edible Uses: Tea.

Young leaves and plants – raw or cooked. Used as a potherb, they are very rich in zinc. A nutritional analysis is available. Seed – raw or cooked. Rather small and fiddly to utilize, they can be used in all the ways that buckwheat (Fagopyrum esculentum) is used, either whole or dried and ground into a powder for use in pancakes, biscuits and piñole. The leaves are a tea substitute
Chemical Compositions: Polyganum aviculare contains the flavonols avicularin, myricitrin, juglanin, astragalin, betmidin and the lignan aviculin.

Polyganum aviculare is a safe and effective astringent and diuretic herb that is used mainly in the treatment of complaints such as dysentery and haemorrhoids. It is also taken in the treatment of pulmonary complaints because the silicic acid it contains strengthens connective tissue in the lungs. The whole plant is anthelmintic, astringent, cardiotonic, cholagogue, diuretic, febrifuge, haemostatic, lithontripic and vulnerary. It was formerly widely used as an astringent both internally and externally in the treatment of wounds, bleeding, piles and diarrhoea. Its diuretic properties make it useful in removing stones. An alcohol-based preparation has been used with success to treat varicose veins of recent origin. The plant is harvested in the summer and early autumn and is dried for later use. The leaves are anthelmintic, diuretic and emollient. The whole plant is anthelmintic, antiphlogistic and diuretic. The juice of the plant is weakly diuretic, expectorant and vasoconstrictor. Applied externally, it is an excellent remedy to stay bleeding of the nose and to treat sores. The seeds are emetic and purgative. Recent research has shown that the plant is a useful medicine for bacterial dysentery. Of 108 people with this disease, 104 recovered within 5 days when treated internally with a paste of knotweed
The plant has astringent properties, rendering an infusion of it useful in diarrhoea, bleeding piles and all haemorrhages; it was formerly employed considerably as a vulnerary and styptic.

It has also diuretic properties, for which it has found employment in strangury and as an expellant of stone, the dose recommended in old herbals being 1 drachm of the herb, powdered in wine, taken twice a day.

The decoction was also administered to kill worms.

The fresh juice has been found effectual to stay bleeding of the nose, squirted up the nose and applied to the temples, and made into an ointment it has proved an excellent remedy for sores.

Salmon stated:
‘Knotgrass is peculiar against spilling of blood, strangury and other kidney affections, cools inflammations, heals wounds and cleanses and heals old filthy ulcers. The Essence for tertians and quartan. The decoction for colick; the Balsam strengthens weak joints, comforts the nerves and tendons, and is prevalent against the gout, being duly and rightly applied morning and evening.’

The fruit is emetic and purgative.

Other Uses:..Dye…….Yields a blue dye that is not much inferior to indigo. The part used is not specified, but it is likely to be the leaves. Yellow and green dyes are obtained from the whole plant. The roots contain tannins, but the quantity was not given

Known Hazards: Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people. Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) – whilst not toxic this substance can bind up other minerals making them unavailable to the body and leading to mineral deficiency. Having said that, a number of common foods such as sorrel and rhubarb contain oxalic acid and the leaves of most members of this genus are nutritious and beneficial to eat in moderate quantities. Cooking the leaves will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition

Botanical Name :Rumex crispus
Kingdom: Plantae
Order: Caryophyllales
Family: Polygonaceae
Genus: Rumex
Species: R. crispus

Synonym: Curled Dock.Lapathum crispum Garsault [Invalid]. Lapathum crispum (L.) Scop. Rumex elongatus Guss.

Common Name :Curly dock” or “yellow dock

Habitat :Rumex crispus is native to Europe and Western Asia. It grows freely in roadside ditches and waste places.
Description:
Rumex crispus is a perennial plant growing to 0.6 m (2ft) by 0.3 m (1ft in).
It is hardy to zone 5 and is not frost tender. It is in flower from Jun to October, and the seeds ripen from Jul to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Wind.It is noted for attracting wildlife.

The mature plant is a reddish brown color, and produces a stalk that grows to about 1 m high. It has smooth leaves shooting off from a large basal rosette, with distinctive waved or curled edges.The leaves are crisped at their edges. The stem is 1 to 3 feet high and branched, the leaves, 6 to 10 inches long. On the stalk flowers and seeds are produced in clusters on branched stems, with the largest cluster being found at the apex. The seeds are shiny, brown and encased in the calyx of the flower that produced them. This casing enables the seeds to float on water and get caught in wool and animal fur, and this helps the seeds to spread to new locations.

The root-structure is a large, yellow, forking taproot. The roots are 8 to 12 inches long, about 1/2 inch thick, fleshy and usually not forked. Externally they are of a rusty brown and internally whitish, with fine, straight, medullary rays and a rather thick bark. It has little or no smell and a rather bitter taste.

Cultivation:
Succeeds in most soils, preferring a moist moderately fertile well-drained soil in a sunny position[200]. The plant does not need any help in growing, it is doing very nicely in Britain where it is a serious weed of agriculture. A very important food plant for the caterpillars of many species of butterfly[30].

Propagation:
Seed – this plant does not require any help in its propagation.

Edible Uses:
Leaves are eaten raw or cooked. They can also be dried for later use. The leaves can be added to salads, cooked as a potherb or added to soups. Only the very young leaves should be used, preferably before the stems have developed, and even these are likely to be bitter. If used in early spring and in the autumn they can often be fairly pleasant tasting. The leaves are very rich in vitamins and minerals, especially iron and the vitamins A and C. A nutritional analysis is available. Stems – raw or cooked. They are best peeled and the inner portion eaten.

Seed are also eaten raw or cooked. It can be used as a piñole or can be ground into a powder and used as a flour for making pancakes etc. The seed is very fiddly to harvest and prepare. The roasted seed has been used as a coffee substitute.

Medicinal Uses:
Rumex crispus has a long history of domestic herbal use. It is a gentle and safe laxative, less powerful than rhubarb in its action so it is particularly useful in the treatment of mild constipation. The plant has valuable cleansing properties and is useful for treating a wide range of skin problems. All parts of the plant can be used, though the root is most active medicinally. The root is alterative, antiscorbutic, astringent, cholagogue, depurative, laxative and mildly tonic. It used to be sold as a tonic and laxative. It can cause or relieve diarrhoea according to the dose, harvest time and relative concentrations of tannin(astringent) and anthraquinones (laxative) that are present. It is used internally in the treatment of constipation, diarrhoea, piles, bleeding of the lungs, various blood complaints and also chronic skin diseases. Externally, the root can be mashed and used as a poultice and salve, or dried and used as a dusting powder, on sores, ulcers, wounds and various other skin problems. The root has been used with positive effect to restrain the inroads made by cancer, being used as an alterative and tonic. The root is harvested in early spring and dried for later use. Some caution is advised in its use since excess doses can cause gastric disturbance, nausea and dermatitis. The seed is used in the treatment of diarrhoea. A homeopathic remedy is made from the fresh root, harvested in the autumn before frost has touched the plant. It is only used in the treatment of a specific type of cough

The Zuni people apply a poultice of the powdered root to sores, rashes and skin infections, and use infusion of the root for athlete’s foot.

Other Uses:
Dye & Compost

Yellow, dark green to brown and dark grey dyes can be obtained from the roots. They do not need a mordant. An alternative ingredient of ‘QR‘ herbal compost activator. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost.

Known Hazards: Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition. Avoid during pregnancy & breast feeding.

Herbs & Plants

Polygonum fagopyrum

Botanical Name :Polygonum fagopyrum
Family: Polygonaceae
Genus: Polygonum
Kingdom: Plantae
Order: Caryophyllales

Synonyms:Brank. Beechwheat. Le Blé noir. Sarrasin. Buchweizen. Heidekorm. French. Wheat. Saracen Corn.

Habitat: Polygonum fagopyrum is a native of Central Asia, cultivated in China and other Eastern countries as a bread-corn and was first brought to Europe from Asia by the Crusaders, and hence in France is called ‘Saracen Corn.

Description:
It is a herbaceous plant, with a knotted stem a foot or two in height, round and hollow, generally green, but sometimes tinged with red, lateral branches growing out of the joints, which give off alternately from opposite sides, heart-shaped, or somewhat arrowshaped leaves, and from July to September, spreading panicles of numerous light freshcoloured flowers, which are perfumed. They are dimorphic, i.e. there are two forms of flowers, one with long styles and short stamens, the other with short styles and long stamens and are very attractive to bees. It is frequently cultivated in the Middle United States of Arnerica and also in Brabant as food for bees, and an immense quantity of Buckwheat honey is also collected in Russia. It gives a particularly pleasant flavour to honey.

The nut (so-called ‘seed’) has a dark brown, tough rind, enclosing the kernel or seed, and is three-sided in form, with sharp angles, resembling the triangular Beech-nut, hence the name of the plant, Buckwheat, a corruption of Boek-weit, the Dutch form of the name, adopted with its culture from the Dutch, meaning ‘Beech-wheat’ (German Buchweizen), a translation of the Latin name Fagopyrum (Latin fagus, a beech).

By some botanists, the Buckwheat is separated from the Polygonums, receiving the name Fagopyrum esculentum (Moench).

The nut contains a floury endosperm, and though rarely employed in this country as human food is extensively cultivated for that purpose in Northern Europe, North America (where it also goes by the name of Indian Wheat) and in India and the East.

Buckwheat flour is occasionally used for bread, but more frequently employed for cakes, which when baked have an agreeable taste, with a darkish, somewhat violet colour and are a national dish throughout America in the winter. They are baked on gridirons and eaten with maple syrup as breakfast cakes. The meal of Buckwheat is also baked into crumpets, which are popular among Dutch children and are said to be nutritious and easily digested.

By the Hindus, Buckwheat, which is extensively cultivated in the Himalayas, is eaten on ‘bart’ or fast days, being one of the lawful foods for such occasions. Polygonum cymosum (Meism.), the Chinese perennial Buckwheat, and P. Tartaricum Ge.), the Tartary or Rough Buckwheat, also constitute an important source of flour in the East. In Japan, Buckwheat is called Soba, and its flour is prepared in various ways; kneaded with hot water to make a dough, Soba-neri; a kind of macaroni, Soba-kiri; and so on. The grains, steamed and dried, are eaten boiled or made into bread or Manju, a small cake. Its young leaves are eaten as a vegetable and its stalks are used to feed cattle.

In the Russian Army, Buckwheat groats are served out as part of the soldiers’ rations and cooked with butter, tallow or hemp-seed oil. In Germany it forms an ingredient in pottage, puddings and other food.

Beer may be brewed from the grain, and by distillation it yields an excellent spirit, in Danzig much used in the preparation of cordial waters.

The blossoms may be used for dyeing a brown colour.

Cultivation: It is sown in May or June and ripens rapidly, thriving in the poorest soil. The flowers appear about July and the seeds ripen in October, but so tender are the plants that a single night’s frost will destroy a whole crop. As a grian, Buckwheat is chiefly cultivated in England to supply food for pheasants and to feed poultry, which devour the seeds with avidity and thrive on it – hence one of its local names: Fat Hen. Mixed with bran chaff or grain, its seeds are sometimes given to horses, either whole or broken. When used as food for cattle, the hard angular rind must first be removed. The meal is considered specially good for fattening pigs: 8 bushels of Buckwheat have been said to go as far as 12 bushels of barleymeal and a bushel of the seeds to go further than 2 bushels of oats, though all farmers do not quite agree as to the superior food value of Buckwheat. If it is given to pigs at first in too large quantities, they will show symptoms of intoxication. As compared with the principal cereal grains, it is poor in nitrogenous substances and fat, its nutritious properties are greatly inferior to wheat, though as a food it ranks much higher than rice; but the rapidity and the ease with which it can be grown renders it a fit crop for very poor, badly-tilled land which will produce scarcely anything else, its culture, compared with that of other grain, being attended with little expense.

When grown by the preservers of game as a food for pheasants, it is often left standing, as it affords both food and shelter to the birds during the winter. With some farmers it is the practice to sow Buckwheat for the purpose only of ploughing it into the ground as a manure for the land. The best time for ploughing it in is when it is in full blossom, allowing the land to rest till it decomposes.

Whilst green, it serves as food for sheep and oxen, and mixed with other provender it may also with advantage be given to horses. If sown in April, two green crops may be procured during the season.

The best mode of harvesting this grain is said to be by pulling it out of the ground like flax, stripping off the seeds with the hand and collecting these into aprons or cloths tied round the waist.

In the United States, Buckwheat is sown at the end of June or beginning of July, the amount of seed varying from 3 to 5 pecks to the acre. The crop matures rapidly and continues blooming till the frosts set in, so that at harvest, which is usually set to occur just before this period, the grain is in various stages of ripeness. There, after cutting, it is allowed to lie in swaths for a few days and then set up in shocks. Threshing is done on the field in most cases.

It grows so quickly that it will kill off any weeds.

Constituents: The leaves have been found by Schunch to contain a crystalline colouring principle (1 part in a thousand) identical with the Rutin or Rutic acid previously discovered by Weiss in the leaves of the common Rue and probably existing in the leaves of the Holly.

The seeds contain starch, sugar, gum, and various matters soluble in alcohol. A small amount of the glucoside Indican has been found.

Medicinal Uses: Astringent, acrid.

An infusion of the herb has been used in erysipelas, and a poultice made of the flour and buttermilk for restoring the flow of milk in nurses.
