Rhubarb

Rhubarb can be used to make a delicious pudding or pie but if you eat the wrong part it can end up being your last meal. The leaves of this plant have a chemical called oxalate. If you eat them it can make it difficult for you to breathe and also cause seizures, kidney failure, and may even cause death. These stems also have this chemical, though in not a very big amount.
