Cat’s Claw is a member of the Rubiaceae (bedstraw) family.  It is a woody vining plant with signature curving thorns that resemble a cat’s claw.  It grows wild in the Amazon as well as South and Central America.  There are about 20 varieties of this plant.  It can get up to 100 feet long and is an old and well utilized plant by the Indigenous cultures of the Americas. 

Cat’s Claw dates back to the time of the Inca’s. It was considered a sacred herb and is used by several Amazonian tribes even today.  Indigenous Shamans believe it acts as a bridge between the spiritual and physical worlds.  The Ashaninka (believed to be the descendants of the Inca people) live deep in the Amazon jungle and have been using this plant for centuries.  They are the reason cat’s claw is even known today as they taught the neighboring tribes how to use the herb.  They refer to cat’s claw as ‘kug-kukjagul’ ‘ which means ‘the father of all other forest gods.’  The Incan’s believed it to be a plant made for royal blood.  The plant is still greatly used in the Amazon-however the Peruvian government have made it illegal to use the roots due to overharvesting.  The plant is also used there to make furniture and baskets.

In 1926 Arturo Bell, a German scientist, moved to a small town in the Peruvian rain forest called Pozuzo.  He suffered from a rheumatic condition which he was able to alleviate using cat’s claw.  He went on to use the herb to help a fellow townsman with lung cancer (drinking it as a tea three times a day-patient was cancer free after one year). (www.lifeextension.com/magazine/2007/3/nu_catsclaw/page-01)



Since that time cat’s claw has been proven to help with a great many things and come to be studied by scientists across the globe.  Cat’s claw was found to dilate blood vessels, relax smooth muscle and stimulate the immune system in test tube studies.  It has been used in South America for rheumatic conditions, cancer, inflammation, gastric ulcers, intestinal issues, dysentery, arthritis, allergies, viral infections, etc.  It seems that the studies are backing up the majority of its past uses.  In fact, scientific studies have proven it to repair damaged DNA.  (www.ncbi.nlm.nih.gov/pubmed/11515717) Studies also found that cat’s claw extract made recovery of leukocytes after chemotherapy much faster. (www.healthline.com/health/leukocytes-in-urine )

In 2001, study found that those who took 250-350 mg. of cat’s claw extract daily for 8 weeks were found to have significantly less DNA damage following chemotherapy than those on a placebo.  They also had an increase in white blood cell counts-something chemotherapy is known to reduce.

In a double blind study published in the Journal of Rheumatology, cat’s claw extract was found to reduce the pain associated with rheumatism better than a placebo.  It seems that some species of cat’s claw contain compounds called pentacyclic oxindole alkaloids which are immune system modulators.  (www.ncbi.nlm.nih.gov/pubmed/119500006).

Apparently the South Africans believe in this herbs ability to strengthen the immune system.  The use of it is fairly common in that country for HIV and AIDS.  (www.avert.org/global-hiv-and-aids-statistics). Here in the usa they would caution people against using the herb with retrovirals commonly used to treat HIV/AIDS.  Very unfortunate considering a 2011 study showing that cat’s claw worked to enhance the way retrovirals worked to slow the progression of the disease. (www.ncbi.nlm.nih.gov/pubmed/22024968)

In another study published in Food and Chemical Toxicology it was found that cat’s claw given in vitro was found to have anti-herpetic effects. (www.ajcn.nutirion.org/content/79/5/727.full)

Cat’s claw also shows promise with digestive issues.  Scientists found that supplementing with 250 mg of cat’s claw (uncaria tomentosa) had a reduction in inflammation associated with Crohn’s disease. (www.pennstatehershey.adam.com/content.aspx?productld=112&pid=33&gid=000043). It has also proven useful for gastritis, colitis, leaky gut, diverticulitis, stomach ulcers, hemorrhoids and more.



In 2001 an interesting in vivo study done on cat’s claw bark found that it was able to prevent breast cancer cell growth (cytostatic). (www.ncbi.nllm.nih.gov/pubmed/11724307). A 2006 study found in the British Journal of Haematology backed that up.  Cat’s claw was found to contain 5 very potent alkaloids-namely isomitraphylline, isopteropodine, uncarine F, pteropodine and mitraphylline.  At least four of those were found to inhibit leukemia cell growth in lab tests.  Two of those alkaloids were also found to induce cell death in cancer cells (called apoptosis). (Uncarine F and Pteropodine respectively).  (www.ncbi.nlm.nih.gov/pubmed/16445836).

Aside from all the studies-the Cashibo tribe in east Peru have used it for years to cleanse the body and clean the blood.  The Ashaninka use it to clean the kidneys, treat asthma, to recover from childbirth, to combat chronic inflammation, bone pain, ulcers and much more.

WebMD says that some people use it for shingles, parasites, chronic fatigue, Alzheimer’s, gonorrhea, dysentery and glioblastoma.  They also say that cat’s claw has a few side effects, namely nausea, diarrhea and dizziness.  They advise against using cat’s claw if one takes high blood pressure medication, immune modulating drugs, those on Parkinson’s medication, those scheduled for surgery and pregnant/nursing women.  It should also not be taken by those allergic to the Bedstraw family of plants (coffee, madder, bedstraw, gallium, jasmine, gardenia, etc.)  Always consult a qualified physician before beginning any herbal product and/or regimen.
