Cat's Claw is a tropical vine that grows in rainforest and jungle areas in South America and Asia . Many cultures native to the South American rain forest areas have used it as an herbal remedy for hundreds of years. It is believed to have positive effects on and can boost the body's immune system.

The active substances are alkaloids, tannins and several other phytochemicals. Some of the alkaloids have been proven to boost the immune system. The major alkaloid rhynchophylline has anti-hypertensive effects and may reduce the risk of stroke and heart attack by lowering blood pressure, increasing circulation, reducing heart rate and controlling cholesterol.

Other constituents contribute anti-inflammatory, antioxidant and anticancer properties.

It has long been used as a homeopathic treatment for intestinal ailments. Uses include: Allergies, Crohn's disease, gastric ulcers and tumors, parasites, colitis, gastritis, diverticulitis and leaky bowel syndrome. By stimulating the immune system, it can also improve response to viral and respiratory infections. It is also used in the treatment and prevention of arthritis and rheumatism, as well as diabetes, PMS, chronic fatigue syndrome, lupus, cancer and prostate conditions.

Cat's claw has been used to support the immune system and promote kidney health, as well as to prevent and abort pregnancy.
