Guarana, “pro panacea peregrinantum habetur” (von Martius), is made from the roasted seeds. It is “almost identical in its elements with theine and caffeine” (Spruce, i. 181). It is cultivated on the Negro as an article of trade. According to Bates it is made from the seeds of a climbing plant (Paullinia sorbilis) (Bates, ii. 134).
