The Matsuda Poison Suction Kit is a special vacuum pump that can remove poison from a sting in no time. Once you are stung by an insect, it is advisable to remove the poison with the help of this extractor immediately before the poison is absorbed by the body. The more poison that is suctioned out by the pump, the less itching there will be. The pump comes with a suction cap. It is important to have it with you during outdoor activities or camping.
