The gum has been a very useful, and so significant item in commerce for thousands of years appearing in historical records from antiquity, and still is used in arts, crafts, cosmetics, foods and millions of products ranging from ice cream to adhesives.

During the 1st century AD Dioscorides included reference of gum Arabic's.

It is an essential ingredient in food items syrups, gummi candies, marshmallows, chewing gum, and many others. It is the traditional binder in watercolors, is used in stone lithography, photography and printing, as a binder in fireworks, and in adhesives in stamps and cigarette papers.

The fragments of this exudate are nearly odorless, translucent white, yellow-white, to pale amber in color. It is powdered for most uses. It is soluble in water, insoluble in alcohol.
