It's six o'clock in the morning and not only has your alarm clock gone off, but your 'pain' alarm clock has gone off too.

Indeed, it's another day of coping with that arthritic knee.

Even though you're taking a prescription medicine, there is still some lingering pain.

You wish there was something else you could use that would take the edge off.

You finally decide to take the advice of your sister Shirley who has been raving for quite some time about a herb known as Cat's Claw. She claims it just might do the trick.

[Top] Cat's Claw (Uncaria tomentosa) is a large perennial vine found in the Amazon rainforest and Asia. It derives its name from hook-like thorns growing alongside the plant.

Although scientific research has just recently begun to explore its beneficial qualities, cultures native to the abovementioned areas have used it for thousands of years for medicinal purposes.

What Conditions Does It Treat
a toxic herb, Acacia gregii, is used instead of it in some products

It's A Treatment For Arthritis

[Top]  Several laboratory studies indicate that Cat's Claw's anti-inflammatory qualities make it an ideal treatment for Osteo- or Rheumatoid Arthritis and other inflammatory conditions.

It is beneficial for other inflammatory conditions such as Bursitis and Gout as well. It has been a traditional remedy for these conditions for over 2000 years.

However, researchers felt its best use was for relieving pain and not for reducing swelling associated with Arthritis.


It Decreases Your Risk For Developing Cancer

[Top]  Several preliminary studies indicate Cat's Claw may slow the growth of tumorous Cancer cells.

Moreover, its method of action is thought to be promoting activity of a type of white blood cell known as a macrophage . These macrophages function as scavengers, devouring bacterial and tumor cells.

Furthermore, five of this plant's components have shown antileukemic properties in a laboratory setting.

In fact, several trials have found when taken with conventional Cancer treatments such as chemotherapy, the patients experienced fewer side effects such as hair and weight loss.


Other Conditions It Treats

[Top]   It may also prove beneficial for the following conditions:

  • It may help lower blood pressure, rid the body of excess water, and relax the smooth muscles of the intestines.
  • It may help repair DNA damage caused by chemotherapy or radiation.
  • Third, it may also prove useful in treating an intestinal disorder known as Leaky Gut Syndrome.


How Does It Work ?
there are over 100 medicinal plants in the Amazon rainforests

[Top] Cat's Claw contains several chemicals called alkaloids that enhance immune system function. Indeed, Austrian researcher Klaus Keplinger has obtained two US patents for extracting these alkaloids.

He has isolated six oxindol alkaloids, of which four, according to Keplinger, are appropriate for stimulating the immune system.

As for Arthritis, researchers think it blocks production of two inflammatory substances associated with Arthritis, prostaglandins and tumor necrosis factor. However, researchers feel additional research needs to be done in this area.

Yet, there is some controversy as to what chemicals in Cat's Claw are beneficial. Several years ago, Austrian researchers classified the chemicals in this herb into two distinct groups: pentacyclic oxindole alkaloids (POAs) and tetracyclic oxindole alkaloids (TOAs).

In their final analysis, the researchers found the POAs were responsible for Cat's claw's beneficial effects while the TOAs inhibited the effects of the POAs.

What Does The Research Say?
in South America, it is used as a contraceptive but there is limited research in this area however
  • [Top]  One small study of individuals with Rheumatoid Arthritis that were taking either of the prescription medicines sulfasalazine or hydroxychloroquine achieved pain relief.
  • Also, another study found it could limit arthritic inflammation by 46 to 89%.
  • One 2001 study found it inhibited production of breast Cancer cells by 90%.
  • Additionally, in 1998, Swedish researchers found it inhibited the growth of leukemia and lymphoma cells in the laboratory.
  • In contrast, several studies have seen increases of certain types of Cancer cells from taking this herb.

  • Also, one study found it extended the lives of lymphocytes, which are white blood cells that fight infection.
  • The National Institute on Aging is studying Cat's Claw to see what effect it has on Alzheimer's patients.

Research is ongoing as it is being considered for conditions such as:

  • HIV
  • Multiple Sclerosis
  • Crohn's disease
  • And Systemic Lupus Erythematosus.


Does It Have Any Side Effects?
drug interactions for this herb have not been thoroughly studied

[Top]  There are few side effects associated with this herb but they may include:
  • Nausea
  • Rash
  • Diarrhea
  • Itching
  • Dizziness
  • and allergic inflammation of the kidneys .

Pregnant women should not take it as it may cause a miscarriage.


Although Cat's Claw is a relative newcomer to the herbal scene, it could prove to be a useful addition for treating numerous conditions.

It is our hope that it is a useful treatment for whatever ails you.
