Spogel (Ispaghol husk) is the epidermis separated from the seeds of the Plantago ovata consisting of the tiny transparent flakes each having a brown oval spot. Ispaghula is a plant belonging to the Plantaginacea family which often grows in Pakistan and India. The teguments of the seeds are rich in mucilage. This forms in the stomach, when mixed with cold water, a gel which is not assimilated by the organism but which has multiple benefits. Ispaghula is particularly appreciated during slimming diets for two main reasons : firstly, it naturally takes the edge off hunger ; secondly it slows down the absorption of food during digestion and especially sugar and fat therefore minimizing calorie intake. This high viscosity gel is beneficial to re-educate the intestinal tract which breaks the vicious circle of "classic" laxatives. It increases the volume and the hydration of the stools, making their elimination easier.
