Usos

Uses

Chontaduro is widely used and planted by indigenous communities. Its fruits are high in nutritional value: contains protein, phosphorus, vitamins A, B, and C, iron and calcium, among others. The fruit can be eaten and used in a variety of ways and recipes. The flowers and the palm are also edible and its timber is used for various purposes.

Pigmento

Pigment

The chontaduro provides a green pigment when its leaflets are macerated. This is a very popular plant that can be found easily. Its pigment sets very well on paper, but not on fique (natural fiber); and on cotton it generates a low-intensity, pale green. It does not require exposure to fire to bind to the supports used.

Usos

Uses

In urban areas the tree has ornamental value. It is used as a source of shade in cacao plantations. It contains various toxic alkaloids, which in small amounts can be used for medicinal purposes. Its flowers and seeds are eaten in some countries in the Americas and its leaves can also be used as fodder for cattle.

Pigmento

Pigment

The amacizo produces a green pigment, which is obtained by macerating its leaves. This ink adheres to paper best, creating a strong and intense coloring. On cotton a pale green is obtained, while it does not adhere properly onto fique. It does not require exposure to fire to properly set.
