Cat's Claw -- Una De Gato
Cat's claw, also know as Una de Gato, is, in my opinion, a must
have for everyone. It is useful in cleaning the intestinal
tract, enhancing the power of white blood cells, and is both an
antioxidant and anti-inflammatory. Guess that is why it is so
helpful in dealing with colds and flu.
Early research has show that Cat's Claw is helpful for
people with AIDS, arthritis, cancer, tumors, and ulcers.
Good quality Una De Gato is made from
the inner bark only.
The chemical and nutrient content is from plant sterols,
polyphenols, proanthocyanidins, oxindole alkaloids, quinovic
acid glycosides and triterpenes.
Oh my gosh, what does all that mean.
- cellular protector,
- immune stimulant.
Other Properties/Actions Documented by Traditional Use:
A vine that grows in the highland rainforest's of Peru,una
de gato may take more than two decades to mature. It is known
to climb trees more than 100 feet tall.
It also grows thorns resembling the claws of a cat (hence
its name). In order to protect this highly valued herb, the
Peruvian government restricts harvesting of the root. Only the
inner bark is harvested, leaving the root untouched and able to
regenerate for many years to come. The inner bark provides all
the beneficial alkaloid found in una de gato.

Some quotes from the "authorities". increased attention is
being placed upon "Nature's Pharmacy", the botanical or herbal
nutrients that offer so much hope.
In referring to cat's claw, Newsweek reported that this
"rain forest herb has been long used to treat asthma,
ulcers, and cancer. ("Nature's Biggest Sellers", Newsweek,
November 6, 1995, page 68) In an article in Newlife, this
herb was described as having so many therapeutic uses that
it far surpasses such well known botanicals as Echinacea,
Golden Seal, Astragalus, Siberian Ginseng, as well as
Reishi and Shiitake mushrooms. ("Cat's Claw - A Wonder Herb
from the Peruvian Rain Forest, Newlife, February, 1995)
Excerpted from the book: Herbs of the Amazon - Traditional
and Common Uses, by Dr. Donna Schwontkowski, Doctor of
"Una de Gato is considered one of the most important
botanicals in the rain forest. In Peru, Una de Gato tea is
used as a medicinal herb with almost unlimited curative
properties. This herb is a powerful cellular rejuvenator.
It has been used for the treatment of gastritis
(inflammation of the stomach), ulcers, cancer, arthritis,
rheumatism, irregularities of the female cycle, and acne.
It is also used to treat organic depression. External
applications of Una de Gato include the treatment of
wounds, fungus, fistulas and hemorrhoids. European research
shows that Una de Gato activates the immune system by
increasing lymphocytic (white blood cell) activity."
Excerpted from the book: Traditional Uses of Rainforest
Botanicals by John Easterling:
"It is considered one of the most important
botanicals in the Rainforest. By supporting and enhancing
immune system function, Una de Gato is indicated in a broad
spectrum of conditions including all types of infections.
Urarina tribesman of Peru tell stories of Una de Gato
curing tumors. Una de Gato was one of the plants researched
by the National Institute for Health as an anti-cancer
agent. Studies from various laboratories indicate it
normalizes the immunoglobins by activating T-lymphocytes
Excerpted from the book: Powerful and Unusual Herbs from the
Amazon and China, Published by the World Preservation
"Una de Gato from the Peruvian rain forest is a favorite
for stimulating the immune system. World wide research done
on this powerful herb has led scientists to patent many of
the single chemicals found in it for use in healing cancer,
arthritis, AIDS, and other diseases. However, traditional
wisdom shows that using the whole plant can be far more
powerful than any one isolated ingredient."
To play devils advocate I am also including an article against
Cats claw. Please note the dates on this article 1991 and l995.
A lot has changed in 10 years.
Cat's Claw Not Effective against Cancer William T. Jarvis,
Una de Gato (the English translation of which is cat's claw),
can involve either of two herbs whose scientific names are
Uncaria tomentosa and Uncaria guianensis. It is being quacked
as "a wondrous herb from the Peruvian rain forest," thus
capitalizing upon the current fascination with rain forest
explorations. Reports in the fringe literature typically state
that the herb is used to treat cancer by people in Peru and
then add scientific-sounding information.
A scientific report in the Journal of Natural Products
(1991;54:453-9) states that researchers isolated six new
quinovic acid glycosides from cat's claw samples. Oral doses
inhibited edema (swelling) but showed no significant
anti-inflammatory action on experimentally induced edema in a
Because of anecdotal reports of cat's claw use as a folk
remedy for cancer, the National Cancer Institute has tested
samples. In 1995, an official at NCI's Natural Products Branch
informed me that cat's claw had been put through the cancer and
AIDS screens but did not show sufficient activity to warrant
further testing. Investigation Drugs Branch fax 11/08/95
