Wild Quinine (Parthenium integrifolium)

Wild quinine (Parthenium integrifolium) goes by a variety of names: American feverfew, eastern feverfew, prairie dock, and Missouri snake root.

It has notoriety for the fact some dishonest sellers will try to represent it as echinacea.

I don't know much about this herb except that was used as a diuretic and for the kidneys.
