A bulking herbal laxative - a broom for the colon. Mix with plenty of water. Psyllium husk is an effective bulk laxative mainly used for acute or chronic constipation and colon cleansing. The seed husk is mixed with water and drunk to lubricate and sweep the intestines. Psyllium may help with acid indigestion, general bowel problems, haemorrhoids, irritable bowel syndrome and gastric ulcers, as well as diarrhoea(as it absorbs excess liquid in intestines). Traditionally psyllium has been used topically as a poultice for skin irritation, boils and abscesses, as well as to draw out toxins.
