Normacol Plus Granules Normacol Plus Granules are used to treat constipation in adults & children over 12 years, & to initiate & maintain bowel action after rectal surgery or a haemorrhoidectomy. Normacol Plus Granules contain Sterculia, a gum obtained from the Karaya tree that is naturally high in fibre & Frangula Bark, a gentle laxative. The Stericula forms a soft bulky stool & induces a laxative effect, while the Frangula Bark provides an additional laxative effect to aid the softened stool through the bowel to bring natural relief from constipation.
