The use of tannins for the body
The tannins present in large numbers in the persimmon, dogwood, quince, blueberries, pear, black currant, turmeric, and also in tea and coffee. They give the fruit and leaves of plants characteristic astringent bitter taste. Tannins useful for the body. Many of these compounds reduce the secretory function of the gastrointestinal tract, affect the intestinal mucosa anti-inflammatory effect, have astringent or irritating effect, depending on their concentration. The motility of the intestines slows the absorption of nutrients is more intense, of the intestinal contents becomes drier and firmer.
Tannins are protection of the mucosa from irritants.
By eating fruits rich in tannins, the body receives substances such as catechin and epicatechin. They bind carcinogenic compounds, clean the intestines from toxins, prevent the appearance of inflammatory processes in the gastrointestinal tract, diverticulitis. A lot of tannic substances contained in medicinal herbs (wild cherry, birch, oak bark, St. John's wort, tansy, rhubarb). They have antibacterial, hemostatic, astringent, anti-inflammatory properties.
Tannin contained in green tea, have a bacteriostatic and bactericidal effect against staphylococci, typhoid, paratyphoid, dysentery and other sticks. Clinical studies have shown that the decoction of green tea is a great protivogistaminne means. Essential oils, caffeine, tannins that are included with this drink, acting complex helps to reduce the risk of cancer, interfere with active oxidative processes and mutations of cells.
Green tea displays the body of heavy metals - lead, mercury, cadmium, zinc, and radioactive substances, preventing the emergence of leukemia, radiation sickness.
How to eat foods that contain tannins
Tannins are destroyed by freezing products, so you should prefer fresh fruit and berries. With ferric salts tannin gives a black-green and black-blue color, therefore you must not contact the juice and pulp of the fruit with iron and some other metals. As a result, the quality of the products is deteriorating, so to chop fruits, berries, vegetables should be of stainless steel knives. Fruits containing tannins, should be consumed in between meals or on an empty stomach, because they bind to proteins that do not reach the mucous membrane of the stomach and intestines and does not exert its beneficial action. Excessive consumption of tannin-rich foods can cause constipation.
Advice 2: What is volatile
Phytoncides called biologically active substances formed by plants and have antimicrobial properties. First and foremost, this kind of protection of plants. Some are volatile – such as, for example, essential oils can be extremely beneficial to humans.
Volatile are a kind of plant immunity – and in many cases, a cure for humans. In General, there are two class of these substances: volatile and excretory (i.e. non-volatile). In the summer of one hectare of deciduous forest allocates about two kg of volatile phytoncides in one day.
The term "phytoncid" was introduced by the Soviet scholar B. P. by Tokenism in 1928 and is primarily used in Russian literature.
Volatile especially actively allocated to the damaged plants. Volatile volatile, to which belong the allocation of oak, fir, pine, eucalyptus, have beneficial effects on the human body at a distance. They are able to destroy protozoans and some insects in minutes.
Volatile fir destroy pertussis Bacillus, pine – Bacillus, birch – microbe Staphylococcus aureus. But with rosemary or asnizam should be careful – their excretions are poisonous to humans.
The impact of volatile production is not limited to killing disease-causing bacteria, they also inhibit the proliferation and stimulate the activity of microorganisms that are antagonists to pathogenic forms of microbes.
The use of volatile
The chemical composition of the volatile varies, but almost always includes glycosides, terpenoids and tannins. Paradoxically, the volatile much more effective protection against infections of humans and animals than plants.
The list of plants whose volatile useful to humans is very long: it's sage, mint, sweet clover, wormwood, Thistle, horsetail, Angelica, yarrow and many others.
Both in traditional and in folk medicine for many years actively used drugs containing volatile garlic, onions, St. John's wort, juniper, wild cherry, arborvitae, and many other plants. They successfully compete with the Trichomonas coleitis, heal festering wounds, abscesses and sores. The use of volatile inside the recommended in diseases such as atony of the intestines, flatulence, catarrh of the intestines, hypertension, bronchial and cardiac asthma, putrid bronchitis, and many others.
Alcoholic solutions and extracts of garlic and onions (allilchep and allysa) in small amounts are beneficial to the body, increases the excretion of urine, slow pulse and increase the strength of cardiac contractions. They are also used in colds and intestinal disorders.
