The medicinal properties of the plant have also been known since ancient times. Avicenna recommended preparing a drink from its roots in water sweetened with honey for the treatment of the sciatic nerve, paralysis, and loss of tissue sensitivity. The fruit was also used to make a drink with uxomed for an enlarged spleen. “It cleanses the liver and spleen and opens blockages in them,” wrote Avicenna.

The best soil for madder is light or medium loamy, enriched with humus and well fertilized. It is advisable to sow madder after winter grains, early forage or vegetable industrial crops in an area that was previously fallow.

Before sowing, fall plowing is carried out on the site or the soil is dug up to the depth of a spade, filling each m² of land with 2 kg of humus or compost, then the site is harrowed and cultivated to a depth of 6-7 cm. The seed is treated before sowing with Granosan at the rate of 2 g of the drug per 1 kg of seeds.

In the fall, the plant should be earthed up, and from the second year of growing season in early spring, remove dead ground organs and add a nitrogen-phosphorus complex to the soil at the rate of 3 g of fertilizer per m².

Baba Yaga

In Slavic mythology, the old forest sorceress. According to Slavic fairy tales, Baba Yaga lives in the forest, in a hut “on chicken legs.” This hut is depicted as standing either in the thicket of a forest (the center of another world), or at the edge of the forest, but then the entrance to it is from the forest, that is, from the world of death. The name “chicken legs” comes from “chicken”, that is, smoke-fuelled pillars, on which the Slavs placed a “death hut” - a small log house with the ashes of the deceased inside. This burial rite existed among the ancient Slavs until the 9th century.

Baba Yaga, inside such a hut, seemed to be like a living dead - she lay motionless and did not see the person who had come from the world of the living (the living do not see the dead, the dead do not see the living). She recognized his arrival by the smell - “it smells of the Russian spirit” (the smell of the living is unpleasant to the dead). The “chicken legs” of the hut can be simply animals or birds, and Baba Yaga herself has some features of an animal, and sometimes a bear or a goat lives in the hut instead. Baba Yaga is the mistress of time: she is served by the Red, White and Black riders, that is, morning, day and night.

A person who encounters Baba Yaga's hut on the border of the world of life and death, as a rule, heads to another world to free the captive princess. To do this, he must join the world of the dead. Usually he asks Baba Yaga to feed him, and she gives him food from the dead. There is another option - to be eaten by her and thus end up in the world of the dead. Having passed the tests in Baba Yaga's hut, a person finds himself belonging to both worlds at the same time, endowed with many magical qualities, subjugates various inhabitants of the world of the dead, defeats the terrible monsters inhabiting it, wins back a magical beauty from them and becomes king.

Madder: reviews from people after treatment

Preparations based on madder have proven themselves to be effective in the treatment of urolithiasis. For small stones in the kidneys or bladder, they are very effective.

Many patients suffering from gout claim that a decoction of madder root helped them alleviate the condition.

True, treatment courses must be carried out several times a year.

The taste of decoctions, tinctures, and infusions cannot be called pleasant. The brewed bright red composition is very bitter, but over time you can get used to it. It is important that madder really helps.

Application of crappie

The use of kappa as a dyeing substance was based on the content of pigments in it: alizarin and purpurin. Alizarin in crappie is, however, not in a free state, but in the form of a glycoside of ruberythric acid, which, during fermentation or under the influence of acids, breaks down into sugar and alizarin, according to the equation: C26H28O14 + 2H2O = C14H8O4 + 2C6H12O6.

The classic work of Graebe and Lieberman showed that both alizarin and purpurin are derivatives of the anthracene hydrocarbon: the first is dioxyanthraquinone C14H6O2(HO)2, the second is trioxyanthraquinone C14H5O2(HO)3. These works served as the basis for a vast branch of the chemical industry, the production of artificial alizarin, which quickly replaced K. and krapp preparations and K. extracts from dyeing practice. According to Rosenstiel's research, purpurin, another madder pigment, is found in potassium not in the form of a glucoside, but in the form of a carboxylic acid, pseudopurpurin, which, when heated with water, decomposes into purpurin and carbon dioxide.

In addition to alizarin and purpurin, two other substances were isolated from Krap that are genetically very close to alizarin: xanthopurpurin, an isomer of alizarin and munzhistin, a carboxylic acid in composition, standing to alizarin in the same ratio as pseudopurpurin to purpurin. The use of Krap in dyeing practice was based precisely on the ability of alizarin to produce durable and bright colored varnishes with various metal oxides; so, with iron - purple or black, with alumina - bright red and pink, with tin mordant - fiery red, etc.

In particular, significant quantities of Krapa were used in purple dyeing to obtain red, as well as to obtain black and brown colors. In order to, if possible, enhance the coloring ability of madder, its crushed root was very often previously subjected to various treatments, which resulted in an already prepared Krap or the so-called Krap - extract. This kind of pre-treatment more or less completely removed impurities harmful to dyeing: resins, acids, sugary and pectin substances, and when dyeing with K. extract, a more vibrant and bright shade of color was always obtained. One of the most common crappie preparations was garansine; Garance was also used in quite significant quantities. Speckled color (fleur de garance) was prepared by fermenting washed and ground K.; pinkoffin by treating K. in an autoclave with superheated steam; azal represented crude alizarin, extracted from K. with wood alcohol.

The content of useful coloring matter in prepared, washed and dried madder root is no more than 15-20%. This means that in 100 grams of root there are no more than 20 grams of dyes, which can be used to more or less intensely color no more than 100 grams of dyed materials.
