In the 20-30 years of the twentieth century took place in our country industrialization; in the late 30's became apparent threat of war. And for peace, and for the military was needed rubber, and natural (synthetic inferior to him in many ways). Natural rubber is obtained mainly from a tropical plant rubber trees, and for us it was almost inaccessible and too expensive. I had to find my rubber plant. Was engaged in a number of scientists, and found more than 600 plants from which it was possible to get rubber. The best (in the roots of wild plants - up to 27% rubber) proved Kok saghyz - plant intermountain valleys of the eastern Tien Shan, looks almost indistinguishable from ordinary dandelion.
Prepared from the cook-sagyz rubber was no worse than that which was obtained from Hevea (in the 70s it has been confirmed by biochemical studies). Since 1933, the cook-saghyz was introduced into the culture. It was grown mainly in the European part of the Soviet Union, including Belarus. Agronomists have developed special methods of cultivation of kok-sagyz seeds and rubber production. Then it was called "the king of fields" and under the best growing land withdrawn. However, there were many problems in the European part of the USSR Tien Shan dandelion growing too well and quickly rubber-lost property; collect seeds had manually digging shallow roots - also; "Rubber" plantations needed constant weeding, otherwise they quickly "occupied" nekauchukonosny relative - a common dandelion.
Since 1954, in connection with the development of synthetic rubber, isoprene, as well as extremely low profitability of production, Kok saghyz no longer grown.
But the problem of synthetic rubber, scientists can not solve so far - on the qualities he is still inferior to natural. Therefore Hevea juice produced by the same primitive methods that a hundred years ago, is still in demand by modern industry, and every year this need only increases (rubber prices rose from 2002 to 2008 seven times). Unpretentious Kok saghyz can solve the problem with a constant deficit of natural rubber in the world. So his story is not over.
Currently in the U.S., Ford Motor Company and the University of Ohio are exploring the possibility of using alternative sources of rubber for the automotive industry. As producer of latex and considered Taraxacum kok-saghyz (TKS), known as the "Russian dandelion" (English Russian dandelion).
Accepted scientific name dandelion - dandelion, Taraxacum officinale. And indeed, since ancient times it is used for medicinal purposes. All parts of the plant - and the roots and leaves, and flowers - have healing properties.
The plant has choleretic, antipyretic, laxative, expectorant, sedative, antispasmodic and a slight soporific effect. Dandelion and simultaneously acts as a mild diuretic (diuretic) and as a source of potassium (which the body loses when consuming artificial diuretics), ie harmless can regulate fluid balance in the body.
The aqueous extract of the leaves and roots of dandelion increases the overall tone of the body and normalizes metabolism, stabilizes the function of the gastrointestinal tract, lowers cholesterol, reduces the symptoms of hypertension and heart failure. Dandelion is rich in antioxidant vitamins; it is recommended for diabetics, as a tonic in general weakness, for the treatment of anemia.
Experimentally in chemical and pharmacological study of dandelion confirmed TB, antiviral, antifungal, anthelmintic, anti-cancer and anti-diabetic properties. However, no adverse side effects it is not detected.
Juice dandelion leaves smeared with corns, warts, freckles, age spots. Powder of the roots of dandelion helps to restore metabolism and heal festering wounds, burns, ulcers, bedsores. Extracts and extracts, tincture of dandelion roots is taken orally for various diseases. Powder from the dried roots of dandelion is used to enhance the excretion of harmful substances with sweat and urine, as antisclerotic remedy for gout and rheumatism.
Of dandelion flowers make broth (it is used for insomnia, constipation, hypertension) or alcohol infusion (they rub the sore spots for rheumatism)
For the treatment of dandelion need to collect in a clean place, away from the road. Leaves, flowers and juice harvested in June. Better to do it in the morning in the morning after the dew dries. Dandelion roots are harvested in late autumn (under withering leaves) or early spring.
And I read that in the southern European countries (Italy, France) dandelions even specially bred for food. And prepare them not only salads, main dishes but also, in particular, popular cooked and lightly roasted dandelion leaves.
And known from Bradbury "Dandelion Wine" - not a poetic metaphor, and quite common in America drink.
One man was very proud of his beautiful green lawn. Once he saw that among the grass dandelions bloom. The man did not sow these dandelions and therefore took them as weeds. He immediately pulled out their hands. After a short time dandelions reappeared. They disguised themselves as ordinary grass. And people just not trying to get rid of them, dandelions continued to appear on the lawn and grow rapidly. All day long he was indignant and complained. Eventually he lost sleep and even ill. Finally, he wrote to the Department of Agriculture. He mentioned all the methods of weed control. A letter ended question: "I've tried all methods. Advise what to do? " Soon, he received the answer: "We invite you to love them."
