The most ignored and perhaps never eaten part of a banana tree, can reverse aging, diabetes and polycystic ovary syndrome (PCOS). There are so many other health benefits, so much so, you may wonder why we have not known about this part of a banana tree sooner. It has been a staple in most Asian countries. It can be prepared in many different ways in soups, stews, salads and sandwiches. This is one vegetable you need to eat regularly. It is worth it.
