Cat's Claw Extract 4%,15%,3% Alkaloids
Health Benefits
In the mid-1990s, once it became known that cat's claw had potential value for the treatment of serious conditions such as cancer, arthritis, and even HIV infections, it became one of the top-selling herbs in the United States. Unfortunately, this enthusiasm was not backed up by much clinical evidence. Very few well-designed clinical trials with human subjects have been done on cat's claw, but some laboratory and animal studies have been conducted.
Most of the anecdotal evidence (word of mouth only) indicates that it may help to improve inflammatory problems such as osteoarthritis (OA) and prostatitis, immune disorders such as lupus and rheumatoid arthritis (RA), and situations in which a stronger immune system is desired, such as cancer and HIV. On the other hand, some herbal researchers also point out that long-term use of cat's claw might overstimulate the immune system and do more harm than good for some of these conditions.
According to a 2001 article in Alternative Medicine Review, cat's claw also warrants further research because of the worldwide concern over viral diseases. Although these areas have not been fully explored, some experts believe that cat's claw may eventually have potential in fighting chronic viral infections such as AIDS, and also in combating cancer and immune-related conditions associated with aging.
Specifically, cat's claw may help to:
Reduce inflammation. In several laboratory experiments, cat's claw has been shown to demonstrate anti-inflammatory effects; few clinical studies of these properties have been conducted, however. One small four-week trial, reported in the 2001 Inflammation Research journal, found that 30 people with OA of the knee had significant relief from pain during daily activities but no easing of nighttime pain or pain during rest; the control group had no pain relief at all. A number of other inflammatory conditions are also being investigated in association with cat's claw, including allergies and asthma, Crohn's disease, rheumatoid arthritis, bursitis, and tendinitis.
Support cancer therapy. In Germany and Austria, standardized extracts of cat's claw, available by prescription only, are given to some cancer patients under a doctor's care. As an immune-boosting agent, cat's claw may strengthen the general health of people undergoing chemotherapy, radiation, or other treatments for cancer, although this effect has not been thoroughly proven. It is not known whether forms other than standardized extracts would be beneficial for cancer patients.
