I grew this for a while many years ago and I've dealt with it in other peoples' gardens, one in particular had a fine stand. It's never attacked me but I think it has times when it's more or less nasty. It's photosensitive. I'm not sure if that's an accurate use of the word but the rash is made worse in sunlight.
A lot of the family are like that to some extent, celery for one. Celery rash is a condition of market gardeners, my son got it on a holiday job when he was a teenager. My mother says I got it from cowparsley as a child but never since and I've handled enough of it
I stopped growing it because it seeds everywhere, not because it hurt me
