Tradition
Traditional ethnobotany

Native to the forests of Amazonia, cat's claw takes its name from the curved thorns on its stem that allow it to cling to surrounding trees. Andean and Amazonian peoples, notably the Ashaninka, traditionally used its bark for generations, regarding it as a precious liana within their pharmacopoeia. It was later studied and exported from the twentieth century onward, gaining a reputation that today extends far beyond its continent of origin.
