Cat's Claw (Uncaria tomentosa)
Cat's Claw (Uncaria tomentosa)
Cat's Claw is a woody vine native to the Amazon rainforest and other tropical regions of South and Central America. Named for the small hook-like thorns that resemble a cat's claws, this botanical has been used for centuries in traditional herbal practices. Today, it remains one of the most widely recognized Amazonian herbs and is valued for its rich phytochemical profile.
About Cat's Claw
Uncaria tomentosa belongs to the Rubiaceae family and can grow over 100 feet in length as it climbs through the rainforest canopy. Traditionally, the inner bark has been the most commonly prepared portion of the plant, although other parts have also been used in regional herbal traditions.
Cat's Claw has become a popular botanical among herbal enthusiasts interested in traditional Amazonian plants and naturally occurring plant compounds.
Chemistry
Cat's Claw contains a diverse range of naturally occurring phytochemicals, including oxindole alkaloids, quinovic acid glycosides, polyphenols, triterpenes, and proanthocyanidins.
Among its most studied constituents are pentacyclic oxindole alkaloids (POAs), which have been the focus of much of the scientific research surrounding the plant. Researchers continue to investigate how these compounds contribute to Cat's Claw's biological activity, although many of its traditional uses have yet to be fully understood through modern clinical research.
Because Cat's Claw is a whole botanical rather than a single isolated compound, its phytochemical profile naturally varies depending on growing conditions, harvest time, and processing methods.
Traditional Use
For generations, Indigenous communities throughout the Amazon have incorporated Cat's Claw into traditional herbal preparations. The inner bark was commonly simmered into decoctions and consumed as part of daily wellness practices.
Its long history of traditional use has made Cat's Claw one of the best-known rainforest botanicals available today.
Preparation & Suggested Use
Cat's Claw may be prepared in several ways depending on personal preference.

If using powdered Cat's Claw, many people mix it into water, smoothies, or herbal beverages.
