Cashew nut which is atruefruit, firmly attaching to the bottom end of cashewapple, appearing like a clapper in the bell. Botanically, this tiny, bean shaped, graytrue fruit is a drupe, featuring hard outer shell enclosing a single edible kernel known commercially ascashew nut. structurally, this cashew drupe is made up of outer, hard shell and inner, edible kernel. Cashew shell composes of a toxic phenolic resin, urushiol a potent caustic skin irritant toxin and therefore should be eliminated.
