A common plant that many people grow in their gardens, this reddish leaf can possibly kill you. Frequently used in pies and other foods, rhubarb leaves contain oxalic acid which causes kidney stones.

While it would take quite a lot of rhubarb (11 pounds, to be exact) to kill you, it doesn’t take nearly that much to make you sick. Interestingly, rhubarb is used in traditional Chinese medicine for its laxative qualities.
