Cat's Claw Standardized Extract
Una de Gato 500 mg 3% Oxindole Alkaloids
Herbal Protection from the Amazon
Another health secret of the Amazon rainforests is now being revealed in an exciting
new product from Source Naturals called Cat's Claw or Una de Gato, Uncaria tomentosa. Like Pau D' Arco before it, the herb Cat's Claw
has been used in traditional Peruvian herbalism for hundreds of years, but it
is only now getting the attention it deserves in the United States.
Source Naturals Cat's Claw - An Amazonian Treasure for the Western World
This unique herb is actually a high-climbing vine found in the highlands of the
Peruvian Amazon. Cat's Claw is named for its claw-like thorns that resemble a
cat's claw. The bark from the Uncaria tomentosa vine is harvested for two important
reasons: first, many of the highly active components are found in the bark; and
second, the bark can be harvested without needless destruction of the vine, thereby
protecting the delicate Amazon ecosystem.
The biologically active constituents in Source Naturals Cat's Claw have uniquely
protective properties. Researchers have discovered that components extracted from
the herb can enhance the body's natural defenses, help to keep the system balanced
in the face of environmental stressors, and can support intestinal health.
Ongoing studies are being performed to determine the exact constituents in the
vine which are responsible for these activities. Oxindole alkaloids, a group of compounds that strongly affect human physiology, have been identified
in some of the vine extracts. Researchers have also isolated compounds, called
quinovic acid glycosides, that seem to have high free radical scavenging potential.
In addition, polyphenols, triterpenes and plant steroids have been isolated from
Among the plant steroids isolated, campesterol, stigmasterol, and Betasitosterol
hold the most promise. Betasitosterol is a white, waxy substance that has been extensively studied because of its close resemblance in structure
and properties to cholesterol, and for its powerful shielding potential. Betasitosterol
so closely resembles cholesterol that it binds the cholesterol absorptive sites
and prevents cholesterol absorption. The presence of these additional compounds
may further explain the herb's protective and rejuvenating characteristics. While
research unravels the multi-faceted properties of this unique Amazonian herb,
the intrinsic benefits can be enjoyed by all who choose to be proactive in their
quest for optimal health.
Cat's Claw (Una de Gato) has been used by indigenous Peruvians for centuries.
The inner bark contains unique active constituents known as oxindole alkaloids,
which help support the body's immune system.
