Psyllium seed husks, also known as ispaghula, isabgol, or psyllium, are portions of the seeds of the plant Plantago ovata, (genus Plantago), a native of India and Pakistan. Psyllium is used in weight control and for general intestinal health. It contains a spongy fiber that reduces appetite, improves digestion and cleanses the system, making it an excellent choice for healthy dieting. Psyllium can provide the fiber that is missing on low carbohydrate diets.
