Cat's Claw has been used for centuries by native people for arthritis and other ailments.
Cat’s Claw herb is one of the herbs used for arthritis

Cat’s Claw, is a woody vine, that grows naturally in the rainforests of Peru, and in some areas of South and Central America. It was named because of its hook-like horns, resembling a cat’s claws. Its root and bark are considered to be superior by many over Echinacea, Golden Seal, Astragalus, and Mushrooms.There are two different species of Cat’s Claw with important differences (uncaria tomentosa or uncaria quianensis). Uncaria guianensis contains more tetracyclic oxindole alkaloids or TOAs.

Uncaria tomentosa contains more pentacyclic oxindole alkaloids. Native cultures used both species’ bark and root for healing. Both alkaloids were present as they cut the roots and bark, then made the medicinal tea. So often in nature, a natural plant will contain fractions that create a balance between the different medicinal properties. When you isolate certain properties, it often creates an altered natural medicine that does give side effects. You have disturbed the herbs’ natural, balanced healing properties and benefits.
In Peru, many tribes including the Aguaruna, Ashaninka, Cashibo, and Shipibo have used this herb to treat asthma, ulcers, cancer, and other diseases for over 2000 years.
Many of these tribes use it successfully to treat different cancers including female urinary tract cancer:
 The Ashaninka natives in Peru are recorded to have used Cat’s Claw for the longest period of time in their cultural history and are the main people now providing it to commercial companies. They feel the herb restores peace and good health when blockages occur between the mind, spirit, and body.
There are so many potent herbal plants in the Amazon rainforest that are being destroyed by cutting down the plants to make way for more cities.
If this continues, these potent life-saving herbal medicines will be lost forever. The main species used in supplements is uncaria tomentosa, rather than uncaria quianensis which is the more common species in Peru. This has to do with the tetracyclic oxindole alkaloid or TOA content. There is still a lot of controversy over the two species and which is the most effective in health. Before you buy a supplement, look at the ingredient label to see which species of cat’s claw is in the supplement.
How Cat’s Claw is used in Europe and other countries:
 Cat’s Claw is used in osteoarthritis, rheumatoid arthritis, and digestive system problems such as diverticulitis, colitis, gastritis, ulcers, hemorrhoids, and leakly bowel syndrome. Cat’s Claw has been shown to stimulate the immune system so is used with viral infections, shingles, cold sores, herpes simplex, AIDS, and HIV. In Europe and other nations, it is used for cancer, urinary tract cancer, brain cancer, and kidney problems.
What have research studies shown on Cats Claw:
Research studies have shown that Cat’s Claw is an adaptogen. That means that ginseng and certain other herbs, help the whole body to work more effectively. It supports the glands and organs so that they work more harmoniously. This would help with any imbalance or disease. Cat’s Claw is also a detoxifier which means it cleans out toxins from the body.
Cats Claw is anti-microbial, antioxidant, anti-viral, anti-inflammatory, and anti-tumor
Along with Cat’s Claw being an adaptogen, it also possesses other medicinal qualities. Research has shown it to be anti-microbial, antioxidant, anti-viral, anti-inflammatory, and anti-tumor. It also boosts the immune system. Among the researchers is the National Institute for Health which has put it on its list as an anti-cancer herb.
Cats Claw contains anti-cancer properties  In lab research, Cat’s Claw has been shown successful against breast cancer cells, leukemia cells, and other cancer cells. That backs up the native use for cancer documented over time for its value against cancer.
Cats Claw is one of the tools against arthritis. Cat’s Claw research started long ago with a German natural scientist, named Arturo Bell in 1916. He used Cat’s Claw successfully with his arthritis pain. He then shared this knowledge with Luis Schuler, who was dying of terminal lung cancer. He was cured of lung cancer a year later after drinking cat’s claw tea three times a day. So the benefits of Cat’s Claw have been known even in more scientific circles for a long time. <><><><><><
Cats Claw is good for your blood pressure and heart health.One very important researcher and expert on Cat’s Claw is Klaus Keplinger in Austria. Keplinger was issued 4 patents between 1989 and 1990 for his discovery of 6 different alkaloids from the Cat’s Claw root that boost immune function. Another alkaloid, rynchophylline, has been shown in research to help prevent strokes, lower blood pressure, increase circulation, and inhibit plaque formation and clots. Keplinger combined these alkaloids from Cat’s Claw into a medicine sold in those countries.

Dr. Fernando Cabieses, a well-respected professor, researcher, neurologist, and neurosurgeon in Lima, Peru has extensively studied Cat’s Claw. He has written a book, The Saga of Cat’s Claw, giving research evidence on the great value of this herb in treating disease.


Historical Native Use Evidence is Important

Native people do not have access to doctors and antibiotics. They have relied on herbs to heal their disease with success for hundreds and thousands of years. If you have a tumor and it goes away with Cat’s claw, you have to take notice. When this happens many times over years, you have to concede that it must work. Just because you don’t know why only means it has not been researched enough to find out.

The use by Native cultures over the span of generations is a great research trial. It stands to reason, if an herb does not positively affect a health problem, you will discontinue using it. You keep taking something that works.


Native people have used Cat’s Claw with tumors and other diseases for years.

Since these natives survived their tumors and illness, you would have to deduce the herbs worked. Herb use over generations is proof the herb works. These herbs are used by real people who are very ill with no access to standard medicine. Herbal medicine is used in the worst of circumstances where villagers live with poor living conditions, bad water, bugs, and poor housing. In these dire circumstances, herbs work on colds, flu, diarrhea, and diseases like tumors. Death is higher in bad living conditions, but their tribe survives.

If herbal medicine was not successful, their tribe would no longer exist. That should tell you a lot. Civilizations survived because of herbal medicine since time began. We have human life today because herbal medicine works over illness and disease.


Cat’s Claws’ Proven Health Benefits include:

Scientific Research: Numerous research studies conducted on Cat’s Claw have resulted in exciting, positive research that supports the many, very positive health benefits of this important healing herb.


  • Potent Antioxidants: important and effective antioxidant benefits that are superior to many other known vegetables and plants.


  • Effective Anti-inflammatory factors are beneficial and effective in various forms of arthritis including osteoarthritis, RA, knee pain, and arthritis in general.


  • Medicinal properties demonstrated in lab studies that Cat’s Claw stops the replication of breast cancer cells, and other cancer that supports native usage for thousands of years.


  • Holistic veterinarians are using Cat’s Claw today to treat dogs and cats for arthritis and hip dysplasia.


  • Anti-fertility properties so this herb should not be used when trying to get pregnant or during pregnancy. I would not use it during nursing either because of the potent alkaloids. Always consult your OBGYN doctor before taking supplements while pregnant or nursing.


Herb Treatment Is Individual:

The dosage of the Cat’s Claw herb needed to cause an effect is individual. The time needed for healing is individual. The quality of the herb product by itself can either make or break a research project. Research projects have numerous weaknesses and pitfalls. Their results are often wrong. Science is only right until it is proven wrong. In ancient times, it was considered a fact that the world was flat. Women were told that estrogen supplementation was the perfect solution for hormonal health problems.

It was once stated that antibiotic resistance was not an issue. Doctors were educated by greedy German pharmaceutical companies that heroin was not addicting. There have been many lies perpetuated by flawed and fraudulent research studies. The use of an herb over 2000 years seems much more significant. The people who have used these herbs know they work and keep using them because of that. Generations of people lived through cancer and disease before the advent of modern drugs including antibiotics. Some of these native people live to be over 100 years old. They are mentally and physically healthy. Think about it.

Cat’s Claw Quality:

There are several species in the Cat’s Claw family that look similar. These different species vary in their alkaloids and medicinal qualities. Some products being sold do not contain the correct species of Una De Gato. You cannot tell that from looking at the powder. Only microscopic tests can know the truth. Make sure you buy from a quality company that tests its batches of herb material to make sure it is pure Una De Gato.

Warning: Do not take herbs with prescription drugs. Using both together could cause side effects or reduce your need for the medication. Get your doctor’s advice before you take herbs. Find a holistic doctor to give you guidance on using herbs. Most standard medicine doctors do not have education about herbs or using them properly.
