Cat's Claw (Uncaria tomentosa)
Many scientific studies have been conducted on cat?s claw in Peru, Italy, Austria, and Germany. However, thus far no conclusive evidence has been documented to verify its health benefits. Nevertheless, this traditional herb of the indigenous people of Peru has grown in international popularity.
Cat?s claw is traditionally used in Peru to treat cancer, diabetes, Ulcers, Arthritis, and Infections, as well as assist in recovery from childbirth. It is also used as a contraceptive. In addition, cat?s claw is given to women recovering from childbirth.
The optimum dosage of cat?s claw is unknown. Cat?s claw is available in a wide variety of forms and preparations; it is therefore recommended to follow the directions on the product?s label.
In Europe and Peru, cat?s claw is considered a potentially effective treatment for viral disease, including Herpes, Shingles, and feline leukaemia virus. Currently, the therapeutic effects of cat?s claw on allergies, stomach Ulcers, rheumatoid Arthritis, and osteoarthritis are being studied (1).
Cat?s claw appears to be quite safe. However, insufficient data is available to confirm its safety. Young children, nursing and pregnant women, and patients with severe kidney or liver disease should be particularly cautious when using cat?s claw, as its safety for these groups has yet to be established.
European physicians caution against its use in conjunction with hormone treatments, insulin, or vaccines (2).
