Chicory, also known as blue dandelion and ragged sailors, is an
attractive wayside simple that is native to Europe and now naturalized
in North America. For centuries, its long taproot has been harvested to
make a hot beverage, especially during times when coffee beans were
scarce.
Chicory root naturally contains oligofructose and inulin, two forms of soluble fiber that are classified as prebiotics. Prebiotics serve as a food source for beneficial microorganisms that are commonly found in the gut and are widely studied for their role in supporting a balanced microbiome.
Chicory is especially well known for its inulin content and is recognized as one of the richest natural plant sources of this soluble fiber. Because of this, chicory root is frequently used in food products, beverages, and dietary formulations where inulin is desired.
