Click-Away Bite Relief is a revolutionary method for treating the itchiness of insect bites - a couple of clicks and the itching disappears. It reduces the itching and the swelling without the use of sticky creams and chemicals by using the power of quartz crystals, which deliver a small electric shock of high voltage and low amps. The pulses (about 5 times) break down the secretion of histamine in the body - this reduces the swelling and itching.
