More About Cat's Claw

With a lengthy history dating back to the Inca civilisation, Cat’s Claw has been used as a traditional medicine in the Andes to treat inflammation, gastric ulcers, rheumatism, dysentery, intestinal complaints and wounds.
The tribes of the Amazon have used this woody vine as a general tonic to promote good health for 1000’s of years – a tonic that can be used to bring anyone back to health.
Its reputation as a “cure all” now seems to be validated by modern science, with numerous studies on the plethora of active compounds shedding new light on this ancient herb.
Cat’s claw plant is known by many names, including Uña de Gato and Samento. There are two cat’s claw species that have been used for medicinal purposes: Uncaria tomentosa and Uncaria guianensis.
In the U.S., U. tomentosa is commonly used, while U. guianensis is popular in Europe. Cat’s Claw’s potential for boosting health mainly comes from the oxindole alkaloids found in its roots and bark. These seven alkaloids are said to stimulate the immune system, leading to this herb’s various medicinal and healing benefits.
Isopteropodin or Isomer A, is the most active alkaloid in this cat’s claw, and is said to help eliminate free radicals from the body. In addition, the plant contains various compounds that can help eradicate harmful bacteria, viruses and other microorganisms, by increasing the white blood cell count in the body which then stimulates antioxidant action.
This herb helps maintain good gastrointestinal health. People with leaky gut, irritable bowel syndrome and other digestive system disorders may find cat’s claw particularly useful, as it can help cleanse the digestive tract and ensure good gut flora.
It suppresses the TNF-alpha synthesis, therefore helping relieve symptoms associated with gout, arthritis and other inflammatory diseases.
Cat’s claw is also known to enhance a specific type of natural killer cell, called CD 57, which is deficient in Lyme disease. It is antiprotozoal and may provide coverage against Babesia.
It combines well with Echinacea and Pau d'arco.

The examined extracts demonstrated slight antiplatelet effects; however, they may be promising candidates for the natural inhibitors of TH, which is critical for the formation of fibrin clot.

Changes in Human Erythrocyte Membrane Exposed to Aqueous and Ethanolic Extracts from Uncaria tomentosa
We consider that the compounds from U. tomentosa extracts mainly build into the outer, hydrophilic monolayer of the erythrocyte membrane, thus protecting the erythrocytes against the adverse effects of oxidative stress.

Uncaria tomentosa stimulates the proliferation of myeloid progenitor cells
At the tested doses, Uncaria tomentosa had a positive effect on myeloid progenitor number and is promising for use with chemotherapy to minimize the adverse effects of this treatment.

Antioxidant properties of proanthocyanidins of Uncaria tomentosa bark decoction: a mechanism for anti-inflammatory activity
Thus, our results provide evidence for an antioxidant mechanism underlying the anti-inflammatory activity of cat’s claw and support some of the biological effects of proanthocyanidins, more exactly its antioxidant and radical scavenging activities.

DNA Repair

DNA repair enhancement of aqueous extracts of Uncaria tomentosa in a human volunteer study
There was a statistically significant decrease of DNA damage and a concomitant increase of DNA repair in the supplement groups (250 and 350 mg/day) when compared with non-supplemented controls (p < 0.05). There was also an increased tendency of PHA induced lymphocyte proliferation in the treatment groups.
