Arrowroot is a plant. People use starch taken from the root and rhizome (underground stem) to make medicine.
Arrowroot is used as a nutritional food for infants and for people recovering from illness. It is also used for stomach and intestinal disorders, including diarrhea.
Since ancient times, arrow root has been used in the diet of babies and convalescents since it is easily digested. It relives digestive discomfort like acidity and indigestion since it exerts a mildly laxative effect on the large intestine.
