The seed and leaves are poisonous, containing saponin-like substances, Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching the seed or flour in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish
Berghill, it is a shame you mentioned Water Dropwort, because it really is deadly, especially to grazing stock. I doubt many of the people on this board will ever meet it and do not know what it is, but it is quite common.

Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Even worse they interbreed and destroy the genetic pool.
Sad thing is that the plague of Spanish slugs which were going to cause cars to skid off the road, don't eat the invasive plants either.
They could fill a centre fold with the datura. Family ,dove just think of the hot air on that one !
