The plant has long been a weed of cultivated grain crops, where its seed became a contaminant of the grain and was thus spread from area to area. However, modern efficient seed screening has lead to a great decline in this species, to the point where it has become a rare plant in much of its native range. The plant is also declining as a weed, but it is still reported as a noxious weed in some areas, such as the states of Arkansas, South Carolina and Florida in N. America[

]. Although poisonous, saponins also have a range of medicinal applications and many saponin-rich plants are used in herbalism (particularly as emetics, expectorants and febrifuges) or as sources of raw materials for the pharmaceutical industry. Saponins are also found in a number of common foods, such as many beans.
Saponins have a quite bitter flavour and are in general poorly absorbed by the human body, so most pass through without harm. They can be removed by carefully leaching 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 raw foods that contain saponins.
Saponins are much more toxic to many cold-blooded 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 and make them easy to catch[
