Uncaria tomentosa (Willdenow ex Roemer and Schultes) DC. and its relative Uncaria guianensis (Aublet) Gmell, both from the Rubiaceae family, are vines growing in jungles of South and Central America. They are widely used in folk and complementary medicine under traditional names: ‘Vilcacora’, ‘una de gato’, ‘cat’s claw“, „cat’s crew’, ‘saventaro’, ‘hawk’s claw’, ‘samento’, ‘garabato amarillo’ and ‘Katzenkralle’. In the genus Uncaria there are also other plants with well-known healing properties…
