Cat’s claw, also known as una de gato, is found in the rainforests of Peru. Cat’s claw is credited with boosting the immune system and protecting the body’s cells against oxidative stress. Its ability to fight inflammation is likely due to the presence of beta-sitosterol and campesterol, which may be the reason why it has been somewhat effective in reducing symptoms of arthritis. Although there are no specific scientific studies indicating that cat’s claw is effective in treating any prostate conditions, such as prostatitis and BPH and the urinary symptoms associated with it, this herb is sometimes used for these purposes, largely because of its beta-sitosterol content.
Cat’s claw is available in standardized root and bark extract (containing 3% alkaloids and 15% phenols) in liquid and capsules. A typical dose for arthritis is 100 mg daily of the standardized capsules, and for supporting the immune system, 250 to 350 mg daily. Cat’s claw is not recommended if you have low blood pressure.
