When the duodenum or stomach is attacked by a bacterial infection, it can often lead to duodenitis, characterized by significant pain and discomfort in the stomach, as well as more serious complications. Buttermilk is a naturally soothing and anti-inflammatory substance that is also rich in fats, which can coat the stomach and reduce irritation. The best results are often achieved when buttermilk is mixed with other anti-inflammatory substances, such as honey, sesame seeds, or black pepper. Drinking these mixtures 2-3 times each day can provide rapid relief to duodenitis.
