Oh my... when i was a young teen i had to cut my grandmothers back yard. Her property has a serious drop down a hill that was never cut before. Well i went down there with a weed wacker and needless to say, it was a mass of poison ivy. I was covered head to toe (eyes, mouth, nose too) with a nasty rash. My mother took me to the ER where i got a shot of something and a bath in calamine lotion. Ever since then, not an issue with it.
