The seed is one of the most commonly consumed nuts in the world. The tree is not usually cultivated, the seed being gathered in large quantities from the wild and then exported from there to many other countries. The tree is also harvested from the wild for its wood and for local medicinal use. The tree has not as yet been much cultivated since it is abundant in the Amazon jungle, though some work on cultivating it has been carried out successfully in other humid tropical areas such as Malaya, Sri Lanka and the West Indies[ 63 Title Nuts.
