A woody vine from the Amazon rainforest, Cat's Claw, named after its distinct claw-like shape, is a dietary supplement that is purported to help alleviate symptoms from various ailments. It is available in both liquid form as an extract and in capsule form for easy diet planning. Either way, it comes with anti-inflammatory effects and an overall boost to your immune system. Cat's Claw is believed to smooth out the muscles, promote healthy blood vessels and act as a diuretic. In standard doses, Cat's Claw is perfectly safe, but you should still consult your physician regarding consuming Cat's Claw if you suffer from any bleeding disorders, autoimmune diseases or similar ailments.
