Buttermilk is rich in natural fats that act as anti-inflammatory agents throughout the body, which is precisely what you need when suffering from hemorrhoids. Buttermilk affects hemorrhoids in two ways, by relieving constipation in the gut, thus relieving the strain and stress of difficult bowel movements, as well as by lessening the severity of the internal hemorrhoids. However, some hemorrhoids are also external, and can be further treated by rubbing buttermilk curds gently on the inflamed tissue. This combination of remedies should rapidly clear up your uncomfortable condition.
