Cashew is a cash crop planted for its fruit and seed. 
Both fruit and seed provide numerous nutritional value making the body healthy. 
The oil is good for cooking for its anti-aging properties. It's also used for nourishment of the skin and hair. 
The shell of the nut contain a liquid called cashew nut shell liquid(CNSL) used in industries for production of paint. 
The fruit is delicious serving nutrition for the body. 
Production of cooking oil from the nut, making drink from the fruit and extraction of CNSL are the businesses I will like to establish; beginning with cashew nuts oil production.
