People believed that safe synthetics are okay, but natural is best. Natural polymers play an important role as excipients in any dosage form. The natural polymers are polysaccharides so, they have become broader considerations in pharmaceuticals because of its accessibility and biocompatibility. The utilization of natural polymers in the drug delivery keeps on being a territory of escalating research regardless introduction of new engineered polymers. Starch is a naturally occurring polysaccharide polymer and has vital intrinsic properties that have made its pharmaceutical applications possible. Rice is one of the major sources of starch worldwide. Assam Bora rice (Oryza sativa L, Japonica variety), a gathering of glutinous rice of Assam, has been accounted to contain up to 90% starch. The Bora rice is a festival food in Assam, is described by its dull smooth appearance and consists of basically amylopectin and traces of amylase; it is otherwise called waxy or clingy rice. This review emphasizes the pharmaceutical utility of Bora rice and its starch as a characteristic polymer for drug delivery. It is preferred as a mucoadhesive matrix in a controlled release drug delivery system since it is exceptionally clingy and has splendid gelling property. Additionally, the rice is a typical staple and is biocompatible and promptly accessible subsequently, marked as ‘GRAS’ (Generally Regarded as Safe), which is fundamental rules for any substance to be utilized in food and pharmaceuticals. This article reviews the literature on Assam bora rice and depicts their varied applications and future use in the drug delivery system.
