It is used to treat many ailments including cancer, diabetes,  chronic fatigue syndrome, PMS, poisoning, arthritis, rheumatism and cancer. It is also traditionally used as a contraceptive. These vegetable-derived capsules (both Kosher and Halal certified) are filled by hand with a manual encapsulation machine, not with a high speed automatic machine, and thus, only pure, unadulterated Cat's Claw 5%  Extract is in the capsules. Capsules produced with high speed machines in herbal remedy and vitamin "factories" contain several other ingredients, including preservatives because so many bottles of product are produced at one time, and lubricants to ensure that the machines will run faster and more efficiently. Check their labels! Also, Barlowe's Herbal Elixirs is one of the very few manufacturers that still pack their products in glass whenever possible, even though glass is more expensive.  Barlowe believes that chemicals can leach out of plastic containers and contaminate the contents, and that the use of glass is much better for the environment. The bark of Cat's Claw has been used by South Americans since the Incan civilization to treat a variety of health problems -  including arthritis, stomach ulcers, inflammation, dysentery, and fevers. It was widely used as a form of birth control. The Ashaninka Indian tribe in central Peru has the longed recorded use of this plant. They are also the largest commercial source of Cat's Claw today. The Ashaninka use Cat's Claw to treat asthma, cancer, urinary tract inflammation, ulcers, arthritis, rheumatism and bone pain. Studies now indicate that Cat's Claw may stimulate the immune system, help relax the smooth muscles (such as the intestines), dilate blood vessels (helping lower blood pressure), and act as a diuretic (helping rid the body of excess water). It also has antioxidant properties, helping rid the body of  free radicals that damage cells. Preliminary studies show it may have anti-tumor and anti-cancer effects as well.
