The cashew tree (Anacardium occidentale) is a tropical tree native to Brazil, known for its unique fruit and nut. It can grow up to 14 meters tall and thrives in warm climates. The tree produces a cashew apple, which is a fleshy fruit, and the cashew nut, which is found at the end of the apple. Cashew trees are cultivated in many countries, including India, Vietnam, and Nigeria, primarily for their nuts, which are popular snacks and used in various dishes. The nuts are harvested from the tree's cashew apples and require careful processing to remove toxic substances before they are safe to eat.
