Cat's Claw / Una de Gato Extended
Uncaria tomentosa (TOA-free)
Oxindole alkaloids from TOA-free Cat's Claw (Uncaria tomentosa) powerfully stimulate immune function and show DNA repair capabilities. Multiple clinical studies confirm enhanced NK cell and T-lymphocyte activity in cancer patients. Cat's Claw reduces treatment-related neutropenia (low white blood cells) and shows anti-tumour activity against breast, colon, and leukemia cells.
