This is a common plant easy to find along rivers, in rich grounds and
on humid meadows. When the plant is crushed and rub between the hands,
it produces a not very rich lather, from which it derives its scientific
and vulgar name.

in herbalist shops, but one has to be careful because the plant is
poisonous.
