Product Description

Native to Central and South America, Cats Claw has been used for hundreds of years in traditional folk medicine to treat a variety of health complaints. The reputed health benefits of this indigenous herb have led scientists in the United States and other countries to closely examine its effects in the body. Their findings suggest that this little-known botanical agent exerts powerful anti-inflammatory and antioxidant effects that support DNA repair, joint health, immune function, and normal cell division.*(1) Cats Claw extracts demonstrate powerful antioxidant effects in quenching the dangerous peroxyl and superoxide radicals. Laboratory analysis indicates that the antioxidant power of Cats Claw exceeds that of many extracts of fruits, vegetables, cereals, and medicinal plants.*(2)

Chronic inflammation underlies many diseases that plague aging adults, and cats claw is a potent anti-inflammatory agent. Cats Claw extract inhibits the production of tumor necrosis factor-alpha, an inflammatory messenger that sets the stage for both acute and chronic inflammation.*(3) Cats Claw likewise inhibits the activation of nuclear factor-kappa beta, an inflammatory switch that is associated with cancer and other deadly diseases.*(4,5) Cats Claw also decreased the experimentally induced release of prostaglandin E2, an inflammatory mediator associated with conditions such as arthritis.*(4)

Animal and human studies suggest that, in addition to exhibiting powerful antioxidant and anti-inflammatory effects, Cats Claw naturally boosts the immune system, strengthening its defenses against the multitude of pathogens encountered each day in the air, water, and environment.

In a study of Cats Claws effects on the immune system of rats, eight weeks of cats claw supplementation significantly elevated the animals white blood cell count, suggesting an improved ability to fight off infectious invaders. Adult men who supplemented with Cats Claw for six months likewise experienced an increase in their white blood cell count, indicating enhanced immune function.*(5)

Laboratory experiments offer evidence that the effects of Cats Claw extend to the cellular level and may help preserve the integrity of DNA, the genetic blueprint of the bodys cells. A vital cell component, DNA is highly vulnerable to damage from free-radical assault, which can contribute to the initiation of cancer and other lethal diseases.

To ascertain whether Cats Claw extract can protect delicate DNA from oxidative stress, scientists conducted a study of cultured human skin cells. They found that an aqueous extract of cats claw protected skin cells from death induced by ultraviolet radiation, by increasing the cells ability to repair ultraviolet-light-induced DNA damage.*(6)

Although chemotherapy plays a critically important role in contemporary cancer treatment, its great drawback is that can damage DNA in healthy cells. When adult volunteers who had previously undergone chemotherapy supplemented with water-soluble cats claw extract for eight weeks, they exhibited markedly decreased DNA damage and increased DNA repair. The participants also demonstrated an increase in white blood cell proliferation. This is an important finding, as chemotherapy typically suppresses white blood cell counts and thus increases ones susceptibility to infections. Cats claw may thus provide crucial DNA and white blood cell support to cancer patients undergoing chemotherapy.*(7)

Suggested Usage

As a dietary supplement, take 1-2 capsules 2 to 3 times daily, preferably with meals.

Cats Claw is generally well tolerated and considered non-toxic. According to reports, its only potential side effect is diarrhea. However, since Cats Claw may stimulate the immune system, it should be avoided by those undergoing organ transplants, skin grafts, and immunosuppressive therapy. While evidence suggests that cats claw may benefit rheumatoid arthritis sufferers, it should not be used on a long-term basis in people with autoimmune disorders (such as lupus or multiple sclerosis) until further studies are available. Pregnant or breastfeeding women and children under the age of three should avoid using Cats Claw. Commercial cats claw preparations vary in dosage and standardization of active constituents. The typical dosage of a Cats Claw preparation is up to 350 mg daily. Cats Claw may lower blood pressure, and so should not be used with blood-pressure-lowering drugs.
