Hi nick,that is a fact i didnt know, am growing veggies for first year and came out in a really bad rash on the inside of my forearm,very sore and ugly, the chemist thought it might be from a courgette plant but from the sounds of it might have beent the parsnips.

Hubby hoping would put me off growing courgettes again as he is getting a little fed up of them in every meal!

Will take more care around the parsnips too now, this gardening is a risky business!!
