Hi
of course ivy is a poisonous plant
just have a look on this site

http://en.wikipedia.org/wiki/Poison_ivy

there are numerous information about it if you google poisonous ivy

If I was affected by that I would personally apply on the area Colloidal silver.It makes miracles on such occasions.

Whoa Nellie! :) Poison ivy (Rhus radicans, Rhus toxicodendron) is a very different plant than the plants normally referred to as "ivy" in gardens - English ivy and its kind (Hedera spp.) and Boston ivy (Parthenocissus). Hedera does cause skin reactions in some people, though not as readily as poison ivy; usually it happens when people go ripping it out and get the sap on their skin. Though it's not all that common a reaction, it pays to wear gloves.
