Hazards [3]  The plant is reported to contain a toxic saponin; Although toxic, saponins are poorly absorbed by the body and most pass straight through without any problem.

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;
