what bean has traces of cyanide
Apple seeds contain small traces of cyanide. There goes the 'an apple a day' phrase right out the window. Apples seeds, much like the red kidney beans, contain traces of cyanide. Although, in extremely small amounts, the seeds in one apple aren't enough to kill. Get you feeling nauseated and sick, but not proving to be fatal. But, have enough of them and it is perfectly possible to kill yourself.
