When a bunch of bananas is harvested, the stem/tree is cut away. The tender inner stem is used as food and has many medicinal properties as well. Layers of hard outer stem are peeled away and only the tender inner stem is used. It is very fibrous, so the thread fiber has to be cleaned. The stem is chopped into small bits and soaked in buttermilk or diluted yogurt for half hour. In Southern parts of India, it is cooked as a vegetable and eaten along with rice.

The banana stem has fiber – this is very beneficial for those on a weight-loss program. It is also a rich source of potassium and vitamin B6 which helps in the production of insulin and hemoglobin. Eating banana stem once a week keeps high blood pressure in control. Banana stem also maintains fluid balance within the body. It is a diuretic and helps detoxify the body. The popular belief is that eating banana stem is very good for kidney stones.
