1.) Cashews are seeds, because they grow out of apples, they are technically a seed, not a nut.
2.) Cashew shells are poisonous. Raw cashews are surrounded by a double shell which contain urushiol, a resin that can produce rashes and is toxic to ingest.
3.) Raw cashews are green. Before the seed is roasted, cashews are a beautiful shade of green.
4.)Cashews are related to pistachios, mangos and poison ivy. The poisonous part of the cashew is the same stuff that makes poison ivy “poison” and is also found in the mango plant.
5.)Cashews may be found in your car. The cashew resin is used in industrial products used as brake liners and paints.
