Although it is native to Brazil, the cashew was introduced in the sixteenth century to other tropical countries, including India where the acrid oil from the nut is rubbed into floors to repel attacks by white ants. The name of the nut also originated in Brazil where the tree upon which it grows is called, in the Tupi language, acaju. This word was adopted by the Portuguese, who in the early eighteenth century introduced it to the English, who respelt it as cashew. Cashew is not related to achoo, a word first used in print in 1873 to represent the sound of a sneeze.
