Cat's Claw Bark - Uncaria tomentosa
The traditional application of cat’s claw has been to treat rheumatoid arthritis. The herb is also used for stomach ulcers, gastritis, eczema, "break-bone fever," and liver diseases. Recent clinical studies find that the herb is useful for relieving knee pain.
Since the 1980Ís, cat claw’s most common use in modern herbal medicine is an immune stimulant. The oxindole alkaloids in cat’s claw strengthen the immune system and also improve circulation by lowering blood pressure. The master rain forest herbalist Leslie Taylor has used cat’s claw tinctures and teas to treat cancer and HIV with remarkable success.
