Hazards [1]  The whole plant is poisonous due to its saponin content; Although toxic, saponins are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not 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; The toxic effect of this plant is not caused by saponins, but by calcium oxalate crystals which are found mainly in the fruit;
