All parts of Banana plant can be used in some way or other. The tender stem can be collected from the banana plant after harvesting the fully grown bananas. Cut a foot length of the trunk and remove all outer layers and you will find the solid tender stem inside. Adding Banana stem in your diet is also good for controlling and preventing kidney stones.

Kidney stones form when the minerals in the urine concentrate and stick together. when the stones grow more than 3 mm in size, they may block the urinary tract and cause pain. Calcium oxalate crystals, uric acid and few other components are responsible in formation of kidney stones. You may not even know that you got kidney stones unless it become severe. The following are some of the symptoms which suggest that you may have kidney stone:

Sharp pain that start in your back and move towards the groin
Pain and some times blood during urination.
Frequent urge to urinate.

However, prevention is better than cure. So, how to control and prevent formation of kidney stones ? In ancient Siddha and Ayurvedic medicinal practices, one of the most commonly used item for prevention and control of kidney stones is Banana stem. You can extract the juice from the Banana stem and drink it. If you do not like the taste of raw juice, you can cook banana stem like any other vegetable and add it to your diet.

Yes, there are few research papers submitted on usage of banana stem to control kidney stones. However, I have referred two such articles here which can be accessed from the net.

Another article published in International Journal of Medicinal Chemistry & Analysis, namely, "ICP-MS Technique for Quantification of Potassium and Sodium in Spray-dried Extrzct of Shoot Juice of Banana Plant (Musa Balbisiana) Responsible for Antiurolithiiatic and Diuretic Activity" by Hariharan Ponnambalam and Manimaran Sellappan. Here is an abstract from the article : (quoted from the article) "Based on the above results it may be conclude that the diuretic and urolithiatic activity of musa shoot juice of banana is due to the presence of higher percentage of sodium and potassium.
