What is Cat's Claw Extract?

Uncaria tomentosa is a woody vine that uses its claw-shaped thorns to climb trees, while often reaching heights upwards of 100 feet. Native to tropical climates in Central and South America, cat's claw bark extract has been a part of indigenous healing traditions for thousands of years. Typical preparations of the bark include extractions, infusions, or decoctions as cat’s claw tea.

Cat's claw extract (una de gato in Spanish) refers to at least 20 plants with sharp curved thorns, both native to the South and Central American tropical rain forests, with most of the commercial production focused on Uncaria tomentosa. Ethically harvested cat's claw bark is a major source of income for many Brazilian and Peruvian villages. The plant is a member of the Rubiaceae family.

Cat's Claw Benefits:

1. Treats Arthritis

Multiples studies have confirmed using cat's claw extract to naturally improve both osteoarthritis and rheumatoid arthritis symptoms. In a 2001 study, 45 subjects suffering from osteoarthritis of the knee either took 100 milligrams per day of freeze-dried cat’s claw or a placebo for four weeks.

Researchers found that “pain associated with activity, medical and patient assessment scores were all significantly reduced with benefits occurring within the first week of therapy.” Knee pain at rest or at night and knee circumference were not significantly reduced by cat’s claw during the short trial, but results led researchers to conclude that cat’s claw is an effective treatment for osteoarthritis with no significant side effects.

2. May Fight Cancer

Scientific studies suggest cat’s claw may help kill tumor and cancer cells in test tubes. A 2001 in vivo study demonstrated that the bark of cat’s claw (Uncaria tomentosa) prevented the growth of human breast cancer cell line MCF7 by having antimutagenic and antiproliferative effects on the cancer cells.

Cat's claw extract has also demonstrated its ability to fight against leukemia. A 2006 study published in the British Journal of Haematology was the first to investigate the antiproliferative and apoptotic effects of five highly purified oxindole alkaloids of Uncaria tomentosa, including isopteropodine, pteropodine, isomitraphylline, uncarine F and mitraphylline.

3. Repairs DNA

In vivo studies have shown that water-soluble extracts of cat’s claw (C-Med-100) can enhance DNA repair, mitogenic response and leukocyte recovery after chemotherapy-induced DNA damage. Chemotherapy is a common conventional cancer treatment with many negative side effects, including damage to the DNA of healthy cells.

A 2001 study looked at the effects of using a water-soluble cat’s claw extract (250 and 350 milligrams per day) for eight weeks on adult volunteers who had previously received chemotherapy. The results were truly awesome. There was a significant decrease of DNA damage and an increase of DNA repair in both cat’s claw supplement groups compared to the non-supplement group. The supplement groups also had an increase in white blood cell proliferation, which is also a huge finding since chemotherapy commonly reduces white blood cell counts and increases infection risk.

4. Lowers High Blood Pressure

Studies of cat's claw bark extract as a treatment for hypertension indicate that it may be helpful in naturally reducing high blood pressure. In Traditional Chinese Medicine, a variety of cat’s claw (Uncaria rhynchophylla) has been used to lower blood pressure as well as improve various neurological symptoms.

Cat’s claw has also been shown to inhibit platelet aggregation and blood clot formation. This means that cat’s claw could likely be helpful in warding off heart attacks and strokes by not only decreasing blood pressure and increasing circulation, but by also inhibiting the formation of plaque and blood clots in the arteries, heart and brain.

5. Boosts Immune Function

Both animal and human studies have demonstrated cat's claw bark extract’s powerful immune-boosting abilities. In one animal study, researchers gave subjects a water-soluble extract of cat’s claw (Uncaria tomentosa) for eight weeks. They found that this supplementation significantly elevated subjects’ infection-fighting white blood cell count.

Researchers also observed a repair of DNA, both single and double strand breaks. These two highly impressive findings came with no signs of acute or chronic toxicity in the animal subjects.

6. May Aid in HIV Treatment

Some people with serious viral infections like HIV use cat’s claw as a dietary supplement. They choose cat’s claw because it has been shown to strengthen the immune system. In Southern Africa, HIV and AIDS are major health problems with an estimated 25.5 million people living with HIV in sub-Saharan Africa. (13) The use of traditional remedies for HIV and AIDS is very common in Africa.

However, a 2011 study showed that natural remedies like cat’s claw can have “potentially significant reactions” with antiretrovirals conventionally used to slow down the progression of HIV. Until more substantial human research is conducted, combining cat’s claw with conventional medicines does not appear to be a good idea since it can may lead to unwanted interactions.

7. Combats Herpes

Cat's claw extract also appears to have positive immune system effects when it comes to herpes. The herpes virus can live dormant inside a person’s immune system for a lifetime, periodically causing blisters that burst and turn into open cold sores or ulcers before healing.

A 2011 study published in Food and Chemical Toxicology looked at the effects of different preparations of Uncaria tomentosa on herpes in vitro and found they exhibited antimutagenic and antiherpetic activities. The herpes-fighting ability of cat’s claw is associated with its polyphenols working synergistically with its oxindole alkaloids or quinovic acid glycosides.

8. Improves Digestive Problems like Crohn’s Disease

Researchers are looking into the possible benefits of cat’s claw for people suffering from Crohn’s disease. Crohn’s is an inflammatory bowel disease that causes inflammation of the lining of your digestive tract, which can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition.

Cat's claw bark extract, specifically Uncaria tomentosa, is believed to be able to help fight the inflammation associated with Crohn's. A dosage of 250 milligrams per day is a recommendation for Crohn’s sufferers. If you can naturally calm the inflammation, unwanted Crohn's symptoms should improve greatly.

Cat's claw powder dosage

If you decide to take cat’s claw, note that dosage guidelines have not been established.

However, WHO says that an average daily dose is 20–350 mg of dried stem bark for extracts or 300–500 mg for capsules, taken in 2–3 separate doses throughout the day.Studies have used daily doses of 60 and 100 mg of cat’s claw extract for treating rheumatoid arthritis and osteoarthritis of the knee, respectively.

One potential risk is that many herbal supplements — including cat’s claw — are not tightly regulated by the FDA. Therefore, it’s best to purchase cat’s claw from a reputable supplier to reduce the risk of contamination.Look out for brands that have been independently tested by companies such as ConsumerLab.com, USP, or NSF International.

SUMMARY

Available information to develop dosage guidelines for cat’s claw is insufficient. However, average daily doses range from 20–350 mg of dried bark extract or 300–500 mg in capsule form.
