The ethnobotanical use is to shoothe rheumatic pain.
Our Reina Mora (Purple queen) have a more extense area in its distribution, from the same place in the north to Santa Cruz province.
They prefer the ecotone areas, transition between the forest, and the steppe, climbed to Radal (Lomatia hirsuta), Berberis ssp., Maiten (Maytenus boaria), and Caña Colihue (Chusquea culeou) that grow shorther than in the forests area.
