What is Blackberry?
Blackberry is a flavor that may added to pharmaceutical products such as syrups, solutions, or chewable tablets to make the product more palatable. It may be an artificial or natural flavor. Flavors are regulated for safety by the U.S. Food and Drug Administration (FDA) and are either considered generally regarded as safe or food additives.
