Stinking Hellebore

"In Ox Meadow near Fulbourn. JM.ann.Meth.65.
...The country people frequently give the powder of this plant to their children for the worms. But how dangerous a midicine it is, may be understood by the following accident. Some years ago, when the ground was covered with a very deep snow; a flock of sheep in Ox-Meadow near Fulborn in Cambridgeshire, finding nothing but this herb above the snow, eat plentifully of it. They soon appeared terribly out of order, and most of them died; a few being saved by timely giving them some oil; which made them cast up this herb. Some of those which died, being opened, were found to have their stomachs greatly inflamed. This account I had from the man who attended them. He went with me to the very spot, and as he pointed out the herb which poisoned them, I found it to be this species of Hellebore. Martyn,1732,2:7-8."

I found it today in a little copse near the meadow at Fulbourn.
