| Is there a way you can tell which poisonous plant you came in contact with? For example... in Pennsylvania, a couple years ago I woke up one morning with black stuff on my arm which was in the shape of + sign.... I tried everything to get it off.... soap and water, nailpolish remover, alcohol, even gasoline... nothing worked... then the next day I woke up swollen and itchy and blistery... ewww... was it poison ivy, oak, or sumac? |
