Zap-Ease bite relief is the simplest, most effective, harmless way of stopping the itch and urge to scratch that comes from insect bites. A \'must-have\' for those prone to forgetting to apply their incognito! ‘Clicking ’ Zap-Ease several times around the area of the bite has the effect of localising the poison and inhibiting the histamine release which causes the itch and the urge to scratch. The toxicity of the mosquito bite becomes neutralised, with no harmful effect on the surrounding skin, thus stopping the customary inflammation and unsightly swelling. Zap-Ease is completely safe for the human body and an incredibly effective treatment for insect bites. Clinically tested at the London School of Hygiene and Tropical Medicine the Zap was proven to reduce itching within 5 minutes of use. Not suitable for those fitted with a pacemaker, or for children under 2 years.
