    We continue to get acquainted (beginning) with our green defenders, plants well studied by mankind with amazing, often simply incredible properties. This article presents (Latin name Uncaria Tomentosa). A thousand years of experience proves that in nature there is both a poison and an antidote, what to use depends on our choice. Throughout its development, man has sought

    salvation from diseases in nature and successfully found, because it is natural components, unlike chemically synthesized drugs, that ideally interact with the cells and metabolic processes of the human body. By the way, artificial vitamins are also medicines in their origin, about this in the article

    It grows in the only place on earth - in South America, in dense, humid Peruvian forests along the Amazon River and is a woody vine with sharp "claws" with which it clings to neighboring plants. Creepers can grow up to 40 meters and live up to 30 years. The inhabitants of that area widely used decoctions from the bark, roots and leaves, ointments and other medicines to strengthen the body (i.e., to strengthen immunity), for poisoning (and therefore to cleanse the body) and inflammatory processes (in other words, in the fight against diseases ).

    Uncaria Tomentosa was first described in the 18th century, and the first studies were carried out in 1952 in France. No important discoveries were made, but in 1974 it was rediscovered by a scientist from Austria (Klaus Kleppinger) while researching the life of the Peruvian Indians. He was struck by powerful medicinal properties creepers, then the oncoprotective effect of the cat's claw seemed especially important (it was noted that the Indians did not suffer from cancer). Soon, in various European laboratories in Germany, Great Britain, Austria, Italy, research on the plant continued and real scientific discoveries were made. After the discovery of quinine (a natural cure for yellow fever and malaria) in the 17th century, the discovery of the cat's claw was the second such significant event in herbal medicine.

    It turned out that the cat's claw plant is superior in its properties to the well-known echinacea, ginseng, mushrooms (shiitake, maitake and reishi), astragalus, ant tree and can be used for neurodermatitis, duodenal ulcer and stomach ulcers, allergies, inflammation of the joints, genital herpes, shingles and other diseases. And in 1988, at the international congress, a report was read on the successful use of the cat's claw plant in the treatment of oncology in 700 patients for 4 years.

    The scientific world was also amazed by the fact that due to its strong antioxidant properties, this plant can act on the immunodeficiency virus that causes AIDS, especially when used on early stages diseases. The famous Dr. Brent W. Davis praised the properties of the cat's claw plant: "Uncaria Tomentosa is a world-class plant that has the ability to stop and reverse the development of deep-rooted pathologies, leading to a rapid return to health."

    It has been established that the preparations of this amazing vine are able to activate the cells of our immune system responsible for the destruction of tumor cells (malignant and benign), improve the condition of the blood (including reducing the risk of thrombosis) and even block the reproduction of viruses in our cells and stop the chain reaction of formation without causing addiction or side effects.

    Summing up: the cat's claw plant helps the body in many problems, reflects aggression in several directions at once, so it is indispensable not only in the treatment of already formed diseases, but also for competent prevention.

    P.S.: Many of my readers ask where to buy a cat's claw plant, which complexes from which manufacturer is better to choose, etc. Let me tell you what I myself know about this plant and where you can get it.

    1. The cat's claw plant is not a grass, it is a tree liana. Usually, dried leaves or bark (external and internal) of this vine are used for medicinal purposes and it is not sold in pure form, like regular herbs in our pharmacies. From the region of growth, it (in finished dried form) is supplied in industrial volumes in bulk to the world market of medicinal plants. There, the bark is bought by manufacturers of finished health products from different countries peace. This plant is used, probably, by all companies that work in the field of herbal medicine. Various companies sell ready-made preparations with this plant, they are easy to find on the Internet.

    2. On the world market, the cost of cat's claw raw materials varies from 25 to 100 dollars (maybe more, these data are for 2009), of course, depending on its quality, which, in turn, directly affects efficiency. It's like with tea or coffee - the higher the quality, the more expensive. In addition to normal raw materials, there is also technological waste, which is also sold, of course, very cheaply, but they also called tea, coffee, cat's claw etc. It is not easy for us, consumers, to find out what quality of raw materials is actually used in finished products, agree? We can only determine this when we buy and try, or we can trust the reputation of bona fide manufacturers.

    3. Since we do not have the opportunity, like the Peruvian Indians, to pick leaves or tear off a piece of the bark of a cat's claw, chew it and get all its healing power, we cannot buy bark powder and conjure it ourselves in order to extract valuable substances to the maximum, we are forced to use finished products for health of different manufacturers. How to choose the highest quality complex? A few recommendations:

    Try to determine a quality product or not even before buying it: analyze certificates (not only sanitary and hygienic, but production certificates), ask about the company's reputation, find out if clinical trials have been conducted (self-respecting companies conduct them and publish the results), look for real reviews people about these products, etc.

    Pay attention to the content of cat's claw in 1 capsule or tablet, whether there are other components and how many of them in% or absolute quantity. Here, too, it is not always fair: there are complexes with meager content, but with a price at the average level and even higher. I have seen on the Internet preparations consisting of both pure cat's claw and a mixture of different plants with VERY different amounts of cat's claw and about the same considerable price. It is clear that it is possible to mix different, including quite common, plants in one complex, but at the same time one should adequately treat their cost, and not benefit from the bait - a cat's claw.

    Manufacturers are sometimes cunning, put a meager amount of the famous liana and supplement it with other well-known herbs. For example, this composition: 1 capsule: Proprietary blend: - 446 mg, Cat's claw (Uncaria tormentosa), Echinacea purpurea (Echinacea Purpurea L.), Astragalus (Astragalus membranaceus) - and how much of each is not indicated. Calculation for an inattentive or inexperienced user, that the cat's claw plant is in high demand.

    It is also important for what period of application the complex is designed - for 10 days, 2 weeks or a month. This is important when calculating the cost of the entire course of application. It happens that the package is only for 10-15 days, and the price is like for a monthly course, and as a result it turns out to be unreasonably expensive.

    There is a difference in what form this plant is used - in tablets or in capsules. In tablets, most likely coarse grinding of the bark and pressing, and this is an additional burden on digestion, because like any other dried and crushed bark, cat's claw bark is difficult to digest in our digestive tract. It is not easy to destroy strong molecular bonds and extract those same active substances from the bark, especially if there are problems with the gastrointestinal tract or the enzyme system, in which case the result may be weak and will not appear soon.

    Better in capsules because thorough grinding is more likely. In addition, the capsule protects against oxidation in the air, so the activity of the therapeutic principle lasts longer. It is advisable to find out about the quality of the capsule itself: it is preferable that the capsules are not made from animal gelatin (it is difficult to dissolve and can cause allergies), but from vegetable gelatin.

    I don’t consider the cat’s claw plant in liquid forms, because it’s either an alcohol solution (alcohol definitely doesn’t improve health, and it makes no sense to try to treat one and cripple the other), or, if water, it is saturated with chemical preservatives (which is harmful to health, “ chemistry” is enough in food).

    Basically everything. There are quite a few companies on the Internet, there are plenty to choose from. I hope my recommendations will help to avoid unscrupulous manufacturers who simply exploit fame. unique properties this creeper without bothering to create a truly effective product. After all, it’s not a tricky business to package in capsules or compress into tablets a crumb (or powder) of cat’s claw bark bought in bulk, but creating a quality health product on its basis is a completely different attitude towards consumers.

    I advise you to look for finished products made according to the best modern technologies, they exist (unfortunately not everyone knows about them).

    If you have any questions, ask in the comments. I reply to everyone at the email address you provide. If I do not answer immediately, I'm sorry, but the answer will definitely be, albeit later. Just in case, check your SPAM folder, now mail services indiscriminately send letters with active links there.

    Do you have experience using complexes with the cat's claw plant? Share, judging by the number of comments, this plant is of interest to many.

    P.S .: For all those interested in cat's claw, I want to explain the difference between immunostimulating agents and immunomodulating ones.

    The former can really deplete the body's resources, especially if they are weakened, which usually happens and stimulants are used to solve this. Such intervention can be compared to blows with a whip on the body of a tired horse - the rider stimulates it to run faster. We know what happens - a horse can really run faster, but it ends with a case.

    Therefore, one must be careful in the choice of stimulants and especially in the timing of their use.

    Immunomodulators work quite differently. The unique liana Uncaria Tomentosa contains a number of alkaloids with high biological activity. Back in 1989, the Austrian scientist Klaus Keplinger received a US patent (No. 4844901), in which six specific alkaloids isolated from this plant were patented.

    The essence of the proven action of four of these alkaloids lies in a sufficiently strong modulation (which means improvement or strengthening) of immunity and, above all, cells of the phagocytic system.

    Thus, the active substances of the cat's claw enhance the work of the most important cells of the immune system - phagocytes. They are called killer cells. It is they who are responsible for the destruction of foreign elements, including their own "crazy" cells (for example, those that have begun an uncontrolled process of division in tumor diseases). If the phagocytic link of our immunity copes with its functions, we are not afraid of any cold or flu, micro-enemies will be destroyed.

    The cat's claw has other properties that are important for immunity, for example, the normalization of the level of secretion (production) of immunity mediators, which affect almost all cells of the body, providing intercellular cooperation and control of the internal environment.

    Immunity mediators perform the function of the immunological language of communication of cells with each other, help them learn to understand each other in order to ensure the coordinated work of individual parts of the immune system and the body as a whole.

    Therefore, the immunomodulatory properties of the cat's claw are due to both direct (through the improvement of the activity of the phagocytic link of immunity) and indirect (through the synthesis of endogenous mediators) its effect on various cells of the body involved in the development of the immune response. Therefore, cat's claw normalizes the characteristics of immunity in individuals with both low and high immune status.

    I hope now the difference between stimulation and modeling is more clear? The uniqueness of the cat's claw lies in the fact that it has the ability to bring immunity back to normal with various deviations in its indicators and can be effectively used both in immunosuppression and in immunoaggression.

    Immunologists say: before you think about the use of stimulant drugs, feed your immunity, give the cells of the immune system proper nutrition and support, then synthetic drugs will not be needed.

    The study of the cat's claw plant began in the 1970s, and its practical application-in 1980s, but the plant has become especially popular only in our days. Studies have shown that taking this remedy can dramatically stimulate immune system which is especially important for cancer patients.

    Medicinal properties of cat's claw

    In the jungles of the Amazon Basin, trees are entwined with a lignified tropical liana, the leaves of which are equipped with two curved spikes at the base, resembling cat claws. An herbal preparation derived from the inner bark of the roots of this plant is known as "cat's claw" or "una de gato" (its Spanish name). Although dozens of related species are known, only two species, Uncaria tomentosa and U. guianensis, are collected from the wild (primarily in Peru and Brazil) for medicinal use. big chunks the bark of these plants is a common commodity in the markets of South America; The local Indians have long made tea from this bark and used it to treat wounds, stomach ailments, arthritis, cancer, and other ailments.

    The mechanism of action of the plant

    Modern research has found several active ingredients in it that can increase the activity of the immune system and suppress inflammation. Their presence may explain why this plant has traditionally been used to fight cancer, arthritis, dysentery, ulcers, and other infections and inflammations.

    Prevention of diseases when using Cat's Claw

    Traditionally, this plant has been used to combat pain. Due to its anti-inflammatory action, it can relieve joint pain in arthritis or gout. However, more research is needed to determine the true role played by the claw in the treatment of arthritis and other inflammatory diseases. Some preliminary evidence suggests that cat's claw, when combined with conventional AIDS drugs, may help HIV-infected people by simulating an immune response. Further research is needed in this direction.

    Some experts warn against taking this plant when chronic diseases affecting the immune system, including tuberculosis, multiple sclerosis and rheumatoid arthritis. They believe that the plant can overstimulate the immune system and worsen symptoms. Other doctors recommend taking the drug for autoimmune diseases, including rheumatoid arthritis and lupus. Further research is required.

    Impact on the human body

    In Germany and Austria, doctors prescribe the drug to stimulate immune responses in cancer patients, many of whom are weakened by chemotherapy, radiation, and other conventional cancer treatments. Several compounds present in cat's claw may account for the anti-cancer and immune-boosting effects of this plant. In the 1970s, researchers reported that the inner bark and roots contained compounds called procyanidol oligomers that inhibited the development of tumors in animals. In the 1980s, German researchers identified other compounds in cat's claw that increase the activity of the immune system, in part by stimulating the phagocytic cells responsible for it. These cells ingest and digest viruses, bacteria, and other pathogens.

    Then in 1993 in Italy it was discovered new class compounds-glycosides of quinovic acid, which have many useful properties. These glycosides can act as an antioxidant, protecting the body from cell-damaging free radicals. In addition to its antitumor effect, it can help with long-term infections, such as sinusitis.


    Indications for use of Cat's Claw

    • To strengthen the immune system, which makes the plant useful for sinusitis and other infections

    • Cat's claw should not be taken by pregnant or breastfeeding women. In Peru, this plant has long been considered a contraceptive; in animal experiments, it stimulates uterine contractions. This effect suggests that it may cause miscarriages.

    Facts and Tips for Taking Cat's Claw

    • If possible, choose standardized extracts to ensure you get the correct dose of application. Look for formulations containing 3% alkaloids and 15% polyphenols
    • Buy supplements made from Uncaria tomentosa or U. guianensis. Many products do not actually contain these plants, but ones similar to them or bearing the same name. These include preparations from a completely different plant, Gregg's Acacia (Acacia greggii) from the southwestern parts of the United States. This plant is also called in English cat's claw (cat's claw). The cost of a monthly dose of a real claw is approximately $20 - $30.
    • Even though the roots may contain a higher percentage of active ingredients than the inner bark, the bark appears to be preferable for environmental reasons. When the inner bark is harvested, the vine can remain alive while harvesting the roots kills the plant. If you buy a standardized inner bark extract, you are guaranteed a certain amount of active ingredients.
    • In Germany and Austria, cat's claw extract is considered a potent drug and is sold only by prescription.

    immunomodulatory properties.
    2. Prevent or slow down the growth of cancer cells - oncoprotective properties.
    3. Normalize functionality of cardio-vascular system, prevent thrombosis and regulate blood pressure - a cardioprotective property.
    4. Cat's claw removes toxins from the intercellular space and from the intestines - a detoxifying property.
    5. Anti-inflammatory properties.
    6. Promotes accelerated healing of ulcers - anti-ulcer properties.
    7. Antiparasitic properties.

    Functional action of the cat's claw

    The most important functional effect of Cat's Claw preparations is the activation of phagocytes (immune cells), which neutralize the active action of cancer cells, stop their division and "put control" of the immune system. Cat's claw normalizes the level of immunoglobulins in the body - antibodies that neutralize the activity of foreign agents. And this means that preparations of the Cat's Claw normalize the phagocytic link of our immunity - the basis of the immune system.

    Among other things, these drugs activate the production of immune mediators, which provide "communication" or information transfer between immune cells. Thus, Cat's Claw ensures the coordinated work of the immune system to protect the body. And this hard work: the system "receives" a signal that a foreign element has invaded the body, it identifies it, "determines" methods for neutralizing this element, "transmits a command" to the appropriate immune cells and those do the work, after which the immune system "commands" other cells to remove the foreign agent from the body.

    Cat's claw contains proanthocyanidin, which neutralizes the harmful effects of free radicals on the body, which slows down the cellular aging process.

    Cat's Claw preparations, thanks to the alkaloid rincofilin (part of the liana bark), help to improve the rheological properties of blood, which prevents thrombosis. Improving the rheological properties of blood "relieves" the load from the heart muscle, which makes it easier for her to work.

    Triterpenes, polyphenols and plant styrenes, which are part of the Cat's Claw, slow down or completely suppress the division of cancer cells, as well as inhibit inflammation.

    Glycyretinic acid and glycosidic glycyrrhizin as part of this vine stop the division of viruses in cells by destroying their genetic material.

    Facts about Cat Root

    In the mid-80s of the last century in Peru, for four years, studies were carried out on the effects of Cat's Claw on the human body in the complex therapy of various oncological diseases. Investigations took place 700 patients. The successful results of this work were presented at an international congress in Lima in 1988.

    Scientists at Mlan University found that Cat's Claw inhibits the human immunodeficiency virus. These studies were carried out on seven volunteers. The five who took the preparations containing Cat's Claw saw noticeable improvements. Moreover, in initial stage manifestations of this pathology disappeared. These studies were conducted in 1992 and the condition of these patients is currently stable.

    Cat root indications and contraindications

    Preparations from this plant are used:
    - in immunodeficiency states;
    - with autoimmune diseases (including lupus erythematosus);
    - with immune diseases;
    - in diseases of the gastrointestinal tract of various etiologies (Crohn's disease, ulcers, gastritis, hemorrhoids, candidiasis, dysbacteriosis ...);
    - for infectious diseases (including acute respiratory infections, acute respiratory viral infections)
    - with neurodermatitis;
    - in diseases of the heart and blood vessels (including arterial hypertension);
    - for the prevention of oncological diseases and with them;
    - with chemotherapy and radiation therapy;
    - with chronic fatigue syndrome;
    - in depressive states;
    - with herpesvirus pathologies;

    Contraindications for Cat Root:
    - individual intolerance to the components of drugs;
    - periods of pregnancy and lactation.

    Cat root instructions for use

    Our preparations based on this plant have clear instructions for use, which we advise you to study before using the drug. But there are general recommendations.

    During the period of taking drugs, drink water - at least 1.5-2.0 liters per day. Water carries trace elements throughout the body (acts as a "transport"), which increases the effectiveness of Cat's Claw preparations.

    How to choose Cat Root preparations

    We will provide advice to help you right choice when buying a drug.

    First, pay attention to the percentage of Cat's Root in tablets or capsules of the drug, since, as a rule, this plant is used with others and its content in the drug is scanty, and the price is high.

    Secondly, evaluate the drug based on the duration of the course of therapy. It happens that a ten-day course is priced the same as a monthly course.

    Thirdly, keep in mind that the coarse grinding of the Cat's root, which is usually present in tablets, is poorly absorbed by the body, for this reason we advise you to buy preparations with this plant in capsule form. In addition, the capsule protects the crushed bark from external exposure to air and the drug retains its properties for a long period.
    AT liquid form cat root we do not recommend buying, as it will be an alcohol solution, or saturated with chemical preservatives.

    Cat root reviews

    Fedor Mironovich Ch., 74 years old, St. Petersburg
    "I dont know the best drug to maintain health than NSP's Cat's Root. My granddaughter "introduced" me to this drug, she is my doctor. Four years brings me jars every three months and I drink them. From the age of 70, my health improves, the years go by, and I feel better than 4 years ago ... "

    Egor Alexandrovich N., 57 years old, Novosibirsk
    "I took two courses of chemotherapy (lung cancer), during this period I used Cat's Claw with the probiotic Unibacter. The doctors were surprised that after these courses my immunity remained in working condition and my recovery is going at a good pace ..."

    At the base of the leaves, these plants bear strong curved spikes that cling to the bark of the twisted trees of the rainforest. Hence the unofficial name uncaria - cat's claw. The genus includes more than a dozen species, but only two are used in medicine - felt uncaria (U.tomentosa) and Guianan (U.guianensis), which are collected mainly in Peru and Brazil. Their inner bark and roots are used, often sold in South American peasant markets.

    Beneficial features uncaria

    Scientists have found in uncaria several biologically active substances with immunostimulating and anti-inflammatory properties. They probably explain the traditional use of these vines to treat cancer, arthritis, dysentery, peptic ulcers, and other infections and inflammations. However, the effectiveness of uncaria has not yet been verified by clinical trials.

    Main benefit

    In Germany and Austria, cat's claw is recommended to boost the immune system of cancer patients who have been weakened by chemotherapy or radiation. Antitumor and immunostimulatory effects have been attributed to several uncaria compounds. Some of them have been studied for decades. In the 1970s, scientists discovered in its inner bark and roots the so-called procyanidol oligomers (PCOs), which inhibit the development of cancerous tumors in experimental animals. In the 1980s, German researchers isolated other immune-boosting compounds from uncaria, in part by stimulating phagocytes, cells that engulf pathogens that enter the body. In 1993, the Italians reported another class of bioactive cat's claw agents, quinovic acid glycosides. Their action is multifaceted. As antioxidants, they neutralize oxidizing free radicals, and in addition, they kill viruses, reduce inflammation, and prevent malignant cell transformation.

    Potentially, cat's claw is useful in preventing cancerous growth and fighting chronic infections such as sinusitis.
