Health Notes

Cat's Claw

Cat's Claw
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Rheumatoid Arthritis
Dose: Refer to label instructions

In a double-blind trial, supplementation with an extract from cat's claw (Uncaria tomentosa) for 24 weeks was significantly more effective than a placebo in reducing the number of painful joints in patients with rheumatoid arthritis. The amount used was 20 mg of extract three times per day. The extract was obtained from a specific strain of cat's claw that contains pentacyclic oxindole alkaloids, compounds that appear to influence the activity of the immune system. The extract was purified to be free of tetracyclic oxindole alkaloids, which may inhibit the beneficial effects of the other alkaloids.1

Immune Function

Cat's claw is another immuno-modulating herb. Standardized extracts of cat's claw have been tested in small, preliminary trials in people infected with HIV, showing some benefits in preventing CD4 cell counts from dropping and in preventing opportunistic infections.1, 2 Further study is needed to determine whether cat's claw is truly beneficial for people with HIV infection or AIDS.

Parts Used & Where Grown

Cat's claw grows in the rain forests of the Andes Mountains in South America, particularly in Peru. The two species of the plant used most commonly are U. tomentosa, which makes up most of the cat's claw imported to the U.S., and U. guianensis, which is more widely used in Europe. In South America, both species are used interchangeably. The root bark is used as medicine.
