The generic name Anacardium is composed of the Greek prefix ana- ( ἀνά-, aná, 'up, upward'), the Greek cardia ( καρδία, kardía, 'heart'), and the New Latin suffix -ium. Its English name derives from the Portuguese name for the fruit of the cashew tree: caju ( Portuguese pronunciation: ), also known as acaju, which itself is from the Tupian word acajú, literally meaning "nut that produces itself". Īnacardium occidentale, from Köhler's Medicinal Plants (1887) The cashew apple is a light reddish to yellow fruit, whose pulp and juice can be processed into a sweet, astringent fruit drink or fermented and distilled into liquor. The shell of the cashew seed yields derivatives that can be used in many applications including lubricants, waterproofing, paints, and, starting in World War II, arms production. As well as the nut and fruit, the plant has several other uses. In 2019, four million tonnes of cashew nuts were produced globally, with Ivory Coast and India as the leading producers. Cashew allergies are triggered by the proteins found in tree nuts, and cooking often does not remove or change these proteins. Like the tree, the nut is often simply called cashew. The cashew seed is commonly considered a snack nut ( cashew nut) eaten on its own, used in recipes, or processed into cashew cheese or cashew butter. The tree can grow as high as 14 m (46 ft), but the dwarf cultivars, growing up to 6 m (20 ft), prove more profitable, with earlier maturity and greater yields. The cashew tree ( Anacardium occidentale) is a tropical evergreen tree that produces the cashew seed and the cashew apple accessory fruit.
