Folklore and History

For the Asháninka Indians Uncaria tomentosa is the totality of their culture. It is depended on so much that traditionally every adult from this tribe carries around Cats Claw bark in a little woven pouch. It is not just the plant they harbour as sacred but what the plant has done for their ancestors. The Asháninka are one Amazonian tribe that live very deep in the jungle, far from habitation and other tribes. It is thought that the Asháninka were the tribe that taught all other Amazonian Indians in the area about the qualities of this amazing plant. Noted by the Polish missionary Father Edmund Szeliga, the Uncaria tomentosa vine was very holy to the Incan people as it is now today to the Asháninka. The latter consider the plant a god incarnate called ‘kug – kukjagui’ and the father of all other forest gods. The high reverence paid to the Cats Claw vine by the Asháninka shows its potent quality as all other medicinal plants are given a lower status. Even for the Incan royal families the Cats Claw was considered only fit for those of royal blood. Not only are the roots, bark and leaf made into concoctions but the bendy vine is also used to make a variety of baskets and rattan furniture. The lower parts of the thick base of the vine are whittled into carvings of other gods showing that the Asháninka regard even the wood as having sacred qualities.

The legend concerning Cats Claw that comes from the Asháninka tells of how Tasurinchi, the first of their people, came to know of the healing qualities of the vine. In the tale Tasurinchi lives in seclusion since there were no other people to help him. He does all the hunting, domestic chores as well as make his home secure which makes his life heavy and unbearable. One day Tasurinchi is rushing through the jungle and meets one by one a puma, a capybara and a tapir. To each he complains of having an ailment; a stomach ache, headache and a deeply cut hand respectively. Each of the animals tells him to use the kug – kukjagui in a different manner to heal his body. Tasurinchi’s life is suddenly transformed from the medicinal Cats Claw properties the animals had shown him. From this moment on the knowledge of the Cats Claw was given to the Asháninka Indians to use for a great many things in their lives. Even today the Cats Claw is of major economic importance to the Asháninka Indians.
