New Traps : Poison trap

When supercell added the poison spell I wondered it is good only for attackers, so i thought about it and now I want to tell you about poison traps.
This trap, like other ones,will appear when.the troops are near it but it has a little different with other, and that is this spell won't cut the HP suddenly, it will do it just like poisen spell.
The troops are toxic when they have met this trap and they will lose their HP for some times and then they will be normal.
But while they are toxic healing effect is blocked untill it is over.
