PSYLLIUM Organic. The seed husk is the most interesting part of psyllium. It is used to treat digestive imbalances. It is also a laxative that works without stimulating digestive secretions or peristalsis. It does not irritate or act as an intestinal sweeper like bran does and, with its mucilage, it softens as it passes through the body. Mix 1 teaspoons of powder in 8 ounces of water or juice at bedtime and drink.
