Uncaria tomentosa extract

Plant Extracts
Also known as Cat’s Claw, there is some research showing it to be an effective anti-inflammatory and antioxidant. There is also some evidence it may have cardiovascular effects by dilating peripheral blood vessels. It may also kill cancer cells without affecting normal cells (Source: www.naturaldatabase.com and Journal of Ethnopharmacology, 2000, pages 115-126).

Conversely, there is research showing it may increase the viability of some cancer cells. (Source: Pediat-ric Blood and Cancer, January 2006, pages 94-98). Research showing it to have antioxidant or DNA-repairing benefits when applied topically has been presented by the Lauder Corporation. (Source: Phytotherapy Research, March 2006, pages 178-183)
