Cat's Claw Extract Supplement: Natural Ingredients to Improve Your Life

By Pierre Federkeil

Because there are so many kinds of cat's claw supplements, such as: cat's claw leaves, cat's claw bark, and cat's claw twigs, cat's claw is one of the most confusing nutritional supplements currently available in health food stores. Although all cat's claw supplements claim to help the immune system, only the root of Uncaria tomentosa gives the true health benefits by possessing the healing power to treat and prevent diseases such as cancer, rheumatoid arthritis, ulcers, degenerative diseases, and also providing anti-inflammatory, anti-viral, and anti-microbial benefits.

However, only those Uncaria tomentosa roots that contain "good spirits," seen by Ashaninka healers of the Ashaninka tribe contain healing properties. If these good spirits are mixed with any root that does not contain good spirits, the healing power is lost. With the use of high performance liquid chromatography (HPLC), scientists can now see the "good spirits" too. These good spirits are actually medicinal compounds called pentacyclic oxindole alkaloids (POAs).

Serious research into the benefits of cat's claw has been underway in Europe since the 1970s, and although, as noted above, conventional medicine remains reluctant to confirm the herb's therapeutic value, the fact that cat's claw is only available on prescription in certain countries is a clear indication of its biochemical potency. Cat's claw's power as an immune system booster appears to be related to unique properties in the alkaloids derived from it, certain of which appear directly to enhance the ability of the body's white blood cells to destroy potentially harmful foreign matter. These alkaloids also seem to stimulate the production of the vital T4 lymphocyte and leucocyte immune system cells which are crucial in fighting viral infections.

One particular such alkaloid, rynchophylline, is also believed to be of great benefit to the cardio-vascular system in preventing blood "stickiness", or the potentially catastrophic formation of clots in circulating blood in the heart and brain. Like other anti-oxidants, cat's claw may also help to prevent the oxidation of low density lipids (LDL), or "bad cholesterol", and the consequent build up of deposits inside the arteries leading to atherosclerosis. Recent research also suggests that the anti-oxidant action of cat's claw may also help to prevent the deposit of the plaques within brain tissue which are implicated in the development of Alzheimer's disease.

The active substances in Cat's Claw are alkaloids, tannins and several other phytochemicals. Some of the alkaloids have been proven to boost the immune system. The major alkaloid rhynchophylline has anti-hypertensive effects and may reduce the risk of stroke and heart attack by lowering blood pressure, increasing circulation, reducing heart rate and controlling cholesterol.

Orthodox medicine, moreover, is always keen to stress, quite correctly, that the mere fact that a remedy is described as "natural" or "herbal" does not mean it is necessarily free of potential side effects. Herbal remedies, after all, often provide the raw materials for the manufacture of conventional drugs, and are highly active biochemical compounds in their own right. They could not be of any benefit if they were not.

Some cat's claw roots have good spirits, POAs, while others tetracyclic oxindole alkaloids, TOAs, which do not help the immune system at all. Since Uncaria tomentosa plants look almost identical, it is hard to tell if they contain healing properties or non-helpful properties. Plants containing POAs one year may contain TOAs the following year because their alkaloid chemotypes change at will. After scientists discovered that they could "see" the presence of TOAs using the HPLC technology, they gained the ability to harvest cat's claw root extracts with POAs consistently. Because buying products that contain TOAs will only benefit the cat's claw distributor due to its canceling effects on POAs, it is important to read the label of the cat's claw root product you are considering buying.

In return for harvesting, the Ashaninka are directly paid by the distributors. This arrangement provides the Ashaninka with the ability to make their own decisions as to how to spend this income, allowing them to make improvements in the tribe's water supply and in their living areas. This arrangement also protects the rain forest, which gives us its many nuts, fruits, oil producing, and medicinal plants. Because of all its products, the rain forest hold more economic value than if it was cut down and used for timber or grazing land for cattle. Cats claw can be purchased at any health food store make sure you check the label to ensure you are receiving the Uncaria tomentosa official Cats Claw. - 17273
