 The nature of treatment for a Myrmecia sting depends on the severity of the reaction . If there are no signs of an allergic reaction , an ice pack or commercially available spray are used to relieve the pain . Washing the stung area , stingose , or the use of antihistamine tablets are other methods to reduce the pain . Indigenous Australians use bush remedies to treat Myrmecia stings , such as rubbing the tips of bracken ferns onto the stung area . Carpobrotus glaucescens is also used to treat stung areas , using juices that are squeezed and rubbed onto the area , which quickly relieves the pain from the sting .
