Banana is sweet and cold in nature. Bananas can sometimes be helpful for stomach upsets caused by heat ie soreness and pain(eat 2 or 3 together). Bananas can also be beneficial for constipation and are good for regulating blood pressure. They are also good for the lungs, and also very good for lung and heart fire which means bananas can have a calming effect and will benefit those with a dry, tickly cough with no phlegm. Its better to eat bananas in the evening, and not in the morning especially on an empty stomach.
