Psyllium Hulls are a popular natural bulk laxative, used in many over-the-counter brands, and is considered beneficial for constipation stemming from either an over-relaxed or over-tensed bowel. Nature's Sunshine Psyllium Hulls increases available water content within the large intestine, thus increasing the bulk of the stool and making its passage easier. This action also helps relieve haemorrhoids by reducing irritation of the distended vein. Furthermore, the soothing, healing effect produced by the mucilage rich husks and seeds helps relive gastrointestinal inflammation associated with acid indigestion and stomach and duodenal ulcers.
