The Gympie Stinger is a large tree native to northern Australia, but also found in New Guinea and other nearby regions. It's incredibly infamous for being completely covered (including stems and fruit) with small silicon hypodermic-like needles. These contain a neurotoxin, causing unbelievable pain in the victim that will not stop until the needles are removed. Furthermore, if they are broken and remain stuck in the subject, they will continue to release neurotoxins when agitated for months or years. This mean a badly treated brush with a single leaf can result in a long term disability. In Oceanyka it has been observed that very rarely, if threatened, the gympie will "shoot" out its stingers in the general direction of whatever is making it sense discomfort. Few species endemic to northern Australia lack protection against gympie stingers, that list unfortunately including humans. To treat a wound from a gympie stinger, it is necessary to remove the hairs. For this one can use tweezers, waxing or tape. The preferable and most reliable method is dropping hydrochloric acid at 10% concentration on the wound and washing afterwards.
