To relieve the pain, itching and swelling of insect bites, Therapik uses the focused application of heat to neutralize the venom. The reason the heat treatment works is that the venom of most common stinging and biting insects is thermolabile, meaning that high temperatures render it harmless.
Applied for less than a minute, Therapik concentrates heat (120° to 140°F/50° to 60°C) on a tiny target area so the heat penetrates as deeply as the venom without damaging surrounding tissue or causing pain.
Effective on the venom of bees, hornets, wasps, mosquitoes, blackflies, ants, jellyfish, fleas, ticks and even stinging nettle (not recommended on spider bites, snakebites or scorpion stings), it works best on fresh bites, but soothes even day-old ones.
It is 6" long and uses one 9V alkaline battery (not included).
