Cashew nut

Cashew is a bean shaped nut that grows on a tropical evergreen tree. The casher tree is related to poison ivy and the shell of the cashew nuts contains an irritating poison. People who touch the shell sometimes develop skin rashes/blisters; this is the reason why cashew nuts are always sold shelled and dried. Even the so-called "raw" cashews have actually been roasted to remove all the poison/toxic resin from the nuts. Cashew nuts has a high content of monounsaturated fats, copper and magnesium.
