3. Castor beans
Many a granny came armed with a spoonful of castor oil to heal all ills, and studies show that it does indeed have health benefits to offer. Just be sure not to eat the beans from which the oil came. If castor beans are chewed and swallowed, they can release ricin, one of the most toxic poisons known to man. Eating just one or two castor beans can easily cause the demise of the eater. Ricin has been investigated as a warfare agent, and has even been employed by secret agents and assassins.

4. Almonds
Any reader of old-school mystery novels knows what the smell of bitter almonds signifies: death by cyanide, my dear Watson. And that's because some plants, including apples and bitter almonds, have cyanide in them to discourage herbivores from devouring them.

But don't fret; bitter almonds aren't the same as sweet almonds, the ones we eat in the United States. Since about 20 bitter almonds are enough to kill an adult, they aren't sold here. That said, almond extract is made with the oil of bitter almonds, but rest assured, it can't be used as a murder weapon.
