Due to allergic reactions after insect bites, we have in addition to Bite Away Cobra bite healer also purchased these Insektengiftentferner. The application for an engraving is easy. You put the appropriate paper according to instructions on the syringe (at least looks like this), pulls the piston and is only now everything in the lurch. Now we pressed under light pressure the piston down. By the resulting vacuum the toxin is extracted and a propagation weitgehends prevented. Depending on the type of stitch or bite must be correspondingly long put and wait. He is partially inserted into our family with mosquito bites, all used in mosquito bites definitely the bite healer Bite Away Cobra, who works with the heat. After I was stung by a bee, the sting did not take off and stuck, I had a lot of pain. Maja was indeed dead, but their sting stuck in my knee. At the sting of a bee is a muscle that is a vesicle, which then despite death of bee venom even further pumped under the skin. The immediate use of Aspivenin Giftentferners has avoided worse. It was interesting to see how after putting in a few seconds by the resulting vacuum liquid was withdrawn from the bee sting. It is important to know that after an engraving one has to use no cold but absolutely Hiitze, as this protein is destroyed. For this reason, we also still use the Bite Away Cobra, is not for wimps, because it tingles minimal or burns at touchdown. I have the the bee sting additionally repeatedly heated with the Bite Away, it has helped. The whole (ie treatment with Giftentferner and Bite Away) I have the next day repeated again because the muscle with bladder and sting of the bee's remained in the skin and even poison was pumped out. Wasp stings I had several times, but as a bee sting is already a different house number. Therefore, a very strong buy recommendation !!!
