The Remarkable Health Benefits of Cat's Claw

5. Lowers Blood Pressure

While Cat's Claw decreases blood pressure, taking it while you're taking medication for high blood pressure can be dangerous. If you're already on blood pressure medications, don't use it as a supplement. If you're not on blood pressure medication, ask a doctor if cat's claw's ability to dilate blood vessels could help you. When the blood vessels dilate, your blood flows in a smoother manner, which decreases the build-up of calcium in the heart and vessel walls and lowers blood pressure.
