Nature's Way Cat's Claw has a guaranteed natural potency of 3 % alkaloids. A traditional tonic herb for well being, Cat's Claw was historically used by the indigenous people of South America for its health promoting benefits. Cat's claw is thought to have anti-inflammatory effects and has been used for rheumatoid arthritis and osteoarthritis. Compounds in cat's claw are thought to block the body's production of inflammation-producing substances called prostaglandins and tumor necrosis factor (TNF). Cat's claw is believed to reduce pain somewhat, but it doesn't appear to have much of an effect on reducing swelling. More evidence is needed before cat's claw can be used as a treatment for arthritis. There's some evidence cat's claw may affect the immune system. Preliminary laboratory studies suggest it may halt the spread of cancer cells. A few animal studies suggest it may help with cell damage caused by chemotherapy or radiation treatment. Much more evidence is needed before it can be used as a cancer treatment, and it should never replace conventional care.

Directions:
Take 3 capsules two to three times daily, preferably with food.
