Cat′s Claw
© Steven FosterParts 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.
- 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.
