Cat's Claw
Description: Cat’s Claw (Uncaria tomentosa) contains oxyindole alkaloids, which appear to be the main reason it works well to stimulate the immune system.1 Other constituents, such as glucosides, make cat’s claw effective as an anti-inflammatory and an antioxidant as well.2
Cat’s Claw has been documented in the Andes for use in treating inflammation, rheumatism, ulcers, and tumors, and even as birth control.

Cat’s Claw grows as a vine in Peru, and takes more than two decades to mature. In most cases, only the inner bark is harvested, so the plant can regenerate and be used again in the next year.

Useful in treatment of: Crohn’s Disease, Immune Function Improvement.

Recommended Dosage: As a tea (1 gram root bark per cup water, steeped at least ten minutes), taken three times daily. As a tincture, 2 to 4 ml daily, taken in two doses. As an extract, up to 60 mg daily.

Contraindications: May be contraindicated in patients with autoimmune illnesses, Multiple Sclerosis, or tuberculosis. Ask a physician before combining with any hormonal medications (including oral contraceptives).
