The truth is in an intermediate place between these two poles, and just as there are dangerous animals for humans, there is also flora that can be harmful and even, as a curiosity, a plant that leads to suicide. The plant that leads to suicide In 1963 Ernie Ryder , an officer of the Service of Parks of Queensland, he was walking in an area of this tropical region of northeastern Australia, when he brushed with his face the leaf of a plant covered with a fluff and known locally as gympie gympie ; what followed next was surprisingly painful: “For two or three days the pain was almost unbearable, I could not sleep or work, and continued to be quite ...
