Saliva is a watery substance located in the mouths of animals, secreted by the salivary glands. Human saliva is 99.5% water, while the other 0.5 onsists of electrolytes, mucus, glycoproteins, enzymes, antibacterial, and bacteria compounds such as secretory IgA and lysozyme. The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, protecting teeth from bacterial decay. Furthermore, saliva serves a lubricative function, wetting food and permitting the initiation of swallowing, and protecting the mucosal surfaces of the oral cavity from desiccation.

Saliba is an indigenous language of Eastern Colombia and Venezuela. Saliba was used by Jesuit missionaries in the 17th century to communicate with indigenous peoples of the Meta, Orinoco, and Vichada valleys. An 1856 watercolor by Manuel María Paz is an early depiction of the Saliva people in Casanare Province.
