The cashew or cashew nut is the fruit of the cashew tree, a tree native to Brazil from the same family as the pistachio or mango tree. The cashew tree is found in tropical areas of America, Africa, and Asia, where it is cultivated for its nuts. Organic cashew nuts are produced by a company that respects its employees. The inside of the cashew nut shell is filled with an acid that is corrosive to the skin. To protect themselves, employees apply coconut oil.
