7) Cashews

While roasted cashews aren’t poisonous, parts of the plant contain caustic compounds that will burn human skin, including the fleshy “shell” that surrounds the nut. And this is why you cannot buy cashews in the shell. Fun fact, even the fumes from roasting the nuts can cause burns and severe skin and lung reactions (similar to burning poison ivy and the two plants are related). The poisonous compounds that can be found in or derived from the toxic part of the plant are used for lumber treatments to fungicides to paint to weapons for the military. Yikes!

Surprisingly the “apple” of the tree from which the nut grows is actually edible!
