Cajú (Cashew nut) is native to northeastern Brazil. Its name derives from the indigenous Tupi name acajú which means “nut which produces”. The stem of the cashew tree produces a yellow resin, known as cashew gum that can replace arabic gum, which is used in the paper industry to the pharmaceutical industry. The Cajueiro (Anacardium occidentale) is small and evergreen tree, growing to 10-12m tall, with a short, irregularly shaped trunk near the ground. Within the true fruit is a single seed, the cashew nut. Its wood is durable and pink.
