Uña de Gato, Powerful Plant


Uña de Gato, Powerful Plant

By Morgan Maher


Uña de Gato, Uncaria tomentosa, or Cat’s Claw is among the most amazing and powerful plants on this planet. Since I first encountered this jungle vine several years ago, it has remained by my side as one of my most trusted and respected guides on the path of health, clarity, energy and immunity. Known also as the Opener of the Way — Cat’s Claw is Jaguar, Panther, Puma, Cougar. It’s one of the Big Cats. King of the Jungle. Uña de Gato is a force.

Further, Uña de Gato is graceful – it prowls, leaps, and moves through the branches of one’s body with ethereal ease and dexterity. It stalks, hunts and pounces on illness and dis-ease as though such things were helpless, unfortunate rodents — devouring, transforming and eliminating them. Amongst plants, Uña de Gato is an assassin, an angel, and simply one of the best spirits one could endeavour to befriend.

Cat’s Claw is well known for it’s beneficial effects upon the whole of the human body and spirit, capable of powerfully cleansing, healing, strengthening and tonifying numerous functions of the human body. It is exceptionally beneficial for the digestive system, especially the stomach and intestines.

Hippocrates — considered the father of modern medicine — stated; “All disease begins in the gut.” Cat’s Claw is supremely adept at hunting down and healing gastrointestinal imbalance and discord. In its cat-like manner it pounces, powerfully, effortlessly, it has you and rips through — wastes no time and gets to work; clawing, cleaning, clearing, repairing. As the plant cleanses these systems on a physical level, it strengthens on a spiritual level one’s intuition, enhances one’s “gut feeling” — offering clarity to one’s life and path.

Hence; “the opener of the way”, a name given to the plant by Dr. Brent W Davis, for its ability to cleanse the entire intestinal tract. Further, this perspective is also connected to the plant’s reputation as “bodyguard”. Cat’s Claw “opens the way” because it strengthens the immune system so well, protects to such a degree, it seems nothing harmful gets near you.

Related to Cat’s Claw’s ability to cleanse the intestines — the gut; “where all disease begins” — it’s immunity boosting capabilities are linked to its powerful anti-inflammatory actions. Again, and from another perspective — that of Chinese herbalism — we see Uña de Gato acting on “the precursor of all disease”; inflammation.

The classical signs of acute inflammation are pain, heat, redness, swelling, and loss of function. Cat’s Claw is excellent at eliminating these things, opening blockages and promoting flow, form and function. It is well regarded traditionally and clinically for treating inflammatory conditions like arthritis, bursitis and rheumatism. In healthier situations where these conditions are not present, Cat’s Claw, in my experience, works very well in keeping the muscoskeletal system –bones, muscles, cartilage, tendons, ligaments, joints, connective tissue — supple, strong, active and ready.




By various names; paraguayo, samento, toroñ, tambor huasca, uña huasca, uña de gavilan, this plant has seen traditional use primarily in Peru, by the Asháninka, Cashibo, Conibo and Shipibo.


The use of Uncaria tomentosa by indigenous healers of tropical South America has not been traced to any particular time in history, but extends for untold past generations as part of of an oral tradition of healing.”


Uncaria tomentosa  is extremely well documented, and has in a sense reinforced its own immunity with the benefits of nearly half a century of ongoing scientific research published in peer-reviewed journals. Early encounters between Klaus Keplinger, (a pioneer in the study and promotion of cat’s claw) and an Asháninkan shaman in 1959, led to the revealing and unravelling of novel oxindole alkaloids, in the early 1970s. In 2011 researchers described oxindoles as “Legendary magic bullets in Bio-medicinal Chemistry”.

Oxindoles exhibit an extensive range of biological effects which include the antiviral, antifungal, antibacterial, antiproliferative, anticancer, anti-inflammatory, antihypertensive and the anticonvulsant activities.


Studies published from the late 1970s to early 1990s indicated that the whole oxindole alkaloid fraction, whole vine bark and/or root bark extracts, or six individually-tested oxindole alkaloids, when used in relatively small amounts, increased immune function by up to 50%. These study results were substantiated by Canadian researchers at the University of Ottawa (1999) and by Peruvian researchers (1998), both working with whole vine extract.”

Two chemotypes were identified for Peruvian U. tomentosa; a tetracyclic oxindole alkaloid type and a pentacyclic oxindole alkaloid type (Laus et al., 1997). Researchers have noted that the pentacyclic oxindole alkaloid type is named savéntaro (powerful plant) by shamans of the Asháninka tribe of Peru (Keplinger et al., 1999).”

The highest order of Asháninka shaman priests use the root bark of U. tomentosa-PC, known to them as savéntaro or powerful plant, to remove the main cause of disease in the Ashaninka’s medico-religious system of healing; a disturbance between the spirit and the body, or an “anxiety.”

Accordingly, U. Tomentosa-PC is used by Asháninka shamans in the treatment of psychological disorders, and is regarded as being inhabited by “good spirits”. It is placed among plants they use for religious purposes which include Banisteriopsis caapi and Erythroxylum coca. The “good spirits” of the vine are said to remove the anxiety state interfering with sprit-body communication, thereby restoring health.”

Cat'sClaw-Vine and Brew sm2


Personally and experientially I have long felt that the Uña de Gato vine bestows similar benefits to the human body as the Ayahuasca vineIn other words — and speaking non-specifically as U. tomentosa and B. Caapi are botanically and chemically different — Cat’s Claw does for the body what Ayahuasca does for the body.

As of this writing I’ve worked with Ayahuasca for nearly 10 years. The first nine months of which were dedicated to working exclusively with the Ayahuasca vine alone — without addition of add-mixture plants like Chacruna (Psychotria viridis) or Chaliponga (Diplopterys cabrerana). It was in this time-frame, this dieta, that I came to know and directly experience the expedience with which Ayahuasca can restore physical health. It is comprehensive and astounding in this capacity.

This experience and work with Ayahuasca formed points of reference for my work and relationship with Cat’s Claw. As I began (and continued) to drink it, I observed similar effects, which, over time were fortified, expanded and enhanced. Cat’s Claw is not psychoactive or visionary in the way Ayahuasca is — it simply makes one feel good, clear, sturdy, and at ease.


The Asháninka expression for “I am healthy” (nocarátanáje) literally means “I carry harmony”

Cat’s Claw, like Ayahuasca, encourages greater and greater degrees of physical and spiritual strength, balance and harmony. However, unlike Ayahuasca, which is neither advised, encouraged, necessary or desirable to consume on a regular basis, Uña de Gato is. Readily available, one can purchase sustainably harvested, fairly traded Cat’s Claw vine, brew it at home, drink it respectfully — without necessarily engaging ceremony or ritual — and go about one’s days with cat-like prowess and power.
