Sometimes the simplest remedies are the most effective, and that is particularly true when using bananas to treat hemorrhoids. Simply mix up a mashed banana with milk and consume the thick shake a 2-3 times each day. The high potassium levels in bananas can help to improve blood flow and water transfer, which can reduce the inflammation in your colon and help to regulate your bowels. The vitamins found in bananas can also help to stop the bleeding and heal the tissues quickly so your hemorrhoids don’t become a chronic problem.
