In the Amazon Rain Forest there are a great botanical diversity where can be found a lot of plants with medicinal proprieties, and for ages it has been used by the native people. One of those plants is Uncaria guianensis known as Cat's Claw to which is believed to have antinflammatories, immunostimulating and growth inhibitors effects on cancerigenic cells. Nowadays, those species have been under uncontrolled and long extraction that could take to extinction. The micropropagation can solve these problems. The purpose of this work was to identify in vitro propagation protocol from these specie. The best medium for embryo germination was ¼ MS independent from presence or absence of saccarose. The explant inoculation position from Uncaria guianensis specie influenciated the shoots average number/original explant, as well as, the initial buds numbers. The giberelic acid presence or absence had not effect on this characteristics, except when explants with only one bud were inoculated in the horizontal position.
