Cat's claw is a tropical vine clinging to 100-foot (and taller) trees by using its namesake "claws."
Cat's claw (una de gato in Spanish) refers to at least 20 plants with sharp curved thorns, both native to the South and Central American tropical rain forests, with most of the commercial production focused on Uncaria tomentosa. Ethically harvested cat's claw bark is a major source of income for many Brazilian and Peruvian villages.
Cat's Claw has been used for viral infections such as herpes and HIV, rheumatoid arthritis gout, lupus, colitis, chorine's disease, candida and has been known to assist with lowering cholesterol. Cat's Claw is a Diuretic, antioxidant, antiviral, immunostimulant and can assist with relaxing and smoothing the muscles.
Usually used as a tincture. The tannins in the herb are released only if it is taken in an acidic medium; add a little lemon juice to a quarter-cup of water to which you add the tincture or prepare as a tea. For convenience it may be taken as a capsule.
