How does NSI® Cat’s Claw work?
NSI Cat’s Claw is an all-natural herbal supplement that provides a powerful 500 mg of Uncaria tomentosa from bark in every dose.
Cat's Claw (Uncaria tomentosa), also known as Uña de Gato and the Healing Vine of Peru, is a South American herb that grows in the Amazon rain forests of the Andes Mountains. It is a highly protected plant in Peru where it grows naturally and is considered a valuable medicinal resource. Dating back to the ancient Incas, Peruvians have used the root bark of this woody vine for centuries for its medicinal properties that may enhance good health.
Cat’s Claw’s inner bark contains many unique active chemical compounds that may help stimulate and support the body's immune system. The oxyindole alkaloids in Cat's Claw give it the ability to boost the function of the body’s immune system. The anti-hypertensive properties in the major alkaloid rhynchophylline may help support cardiovascular health. The alkaloids and glycosides in Cat’s Claw provide healthy antioxidant activity.
NSI® Cat’s Claw is better because it:
- May help to boost the body’s immune system
- Contains powerful anti-inflammatory and antioxidant properties
- Provides a better value than other brands
