Trees that Heal and Feed – Banana Trees

By Liliana Usvat

“In bananas, we have one of nature’s most perfect foods.” – Chris Kilham, for Fox News Health


Farmers in Southeast Asia and Papua New Guinea first domesticated bananas. Recent archaeological and palaeoenvironmental evidence at Kuk Swamp in the Western Highlands Province of Papua New Guinea suggests that banana cultivation there goes back to at least 5000 BCE, and possibly to 8000 BCE.

It is likely that other species were later and independently domesticated elsewhere in Southeast Asia. Southeast Asia is the region of primary diversity of the banana.

Areas of secondary diversity are found in Africa, indicating a long history of banana cultivation in the region.

Bananas were introduced to the Americas by Portuguese sailors who brought the fruits from West Africa in the 16th century.

When added and thoroughly mixed for 40 minutes, the powder can remove roughly 65% of heavy metals, and this can be repeated.

Banana Leaves


Steamed with dishes they impart a subtle sweet flavor. They often serve as a wrapping for grilling food. The leaves contain the juices, protect food from burning and add a subtle flavor. In Tamil Nadu (India) leaves are fully dried and used as packing material for food stuffs and also making cups to hold liquid foods. In Central American countries, banana leaves are often used as wrappers for tamales.

Religion and popular beliefs


Nang Tani, the female ghost of Thai folklore that haunts banana trees

In Burma, bunches of green bananas surrounding a green coconut in a tray form an important part of traditional offerings to the Buddha and the Nats.

In all the important festivals and occasions of Hindus, the serving of bananas plays a prominent part. Traditionally in Tamil marriages, banana trees are tied on both sides of the entrance of houses to bless the newlyweds to be useful to each other. The banana is one of three fruits with this significance, the others being mango and jack fruit.

In Thailand, it is believed that a certain type of banana trees may be inhabited by a spirit, Nang Tani, a type of ghost related to trees that manifests itself as a young woman. Often people tie a length of colored satin cloth around the trunk of the banana tree.

In Malay folklore, the ghost known as Pontianak is associated with banana trees (pokok pisang), and its spirit is said to reside in them during the day.

So I hope I made a case for planting one … or more banana trees and take care of them.
