From afar, the leaves of the gympie-gympie (Dendrocnide moroides) look inconspicuous and even inviting judging from their soft and fuzzy appearance. But nothing could be further from the truth. This is one of the world’s most poisonous plants. A slight brush with its leaves is enough to deliver unimaginable pain that has been described as “like being burnt with hot acid and electrocuted at the same time.” To make matters worse, it can take months or, in some cases, even years before the pain completely goes away. Some have even killed themselves, finding the pain unbearable.
