The root of the chicory plant can be dried, roasted, and ground into a powder that makes for an excellent coffee substitute. It has a rich, earthy flavor and contains no caffeine. Using chicory as an additive or substitute for coffee has been a common practice in Europe since the 19th century.

During World War II and the French occupation, chicory root helped supplement coffee rations. The French and other Europeans still commonly enjoy chicory coffee today.

2. Thomas Jefferson grew chicory at Monticello

Chicory has a long history in the United States as well. None other than Thomas Jefferson grew chicory at his Monticello estate in the late 18th century. Jefferson was interested in chicory as both a coffee substitute and for its medicinal qualities.

3. Chicory root contains the prebiotic fiber inulin

Fresh chicory root contains up to 20% of inulin fiber, which is classed as a prebiotic. Prebiotics help feed the beneficial bacteria that live in your gut, supporting better digestion and wellness.

4. The ancient Egyptians recorded medicinal uses for chicory

The first known record of chicory use by humans comes from ancient Egypt. Chicory is described in Egyptian hieroglyphs from over 4,000 years ago as a medicinal plant used to treat various ailments. The ancient Egyptians mainly used chicory leaves and seeds for medicine.

5. Chicory leaves can be eaten in salads

The young leaves of chicory can be added to salads for a bitter, earthy kick reminiscent of radicchio or endive. When harvested in early spring, chicory leaves are the least bitter and make for a great salad green. They go well with sweet dressings or ingredients like fruit, nuts, and cheese.

6. Chicory coffee may support liver health

Some research indicates that drinking chicory coffee could potentially benefit your liver. A study in rats with liver injury found that chicory coffee reduced liver damage compared to regular coffee. Researchers think specific antioxidants in chicory root called caffeoylquinic acids are responsible for its protective effects. More research is needed, but substituting some coffee for chicory version could support liver health.

7. Chicory root extracts have anti-parasitic effects

Chicory extracts have been shown to kill parasites like roundworms and hookworms in test tubes and animals. One study gave chicory extracts to mice with parasitic infections and found it reduced worm counts by over 90% compared to controls. Researchers think this anti-parasitic effect comes mainly from sesquiterpene lactones, bitter compounds found in chicory’s white milky sap.

8. Chicory could lower blood sugar in diabetes

Some early research shows chicory root fiber could help control blood sugar in diabetes. Inulin from chicory helps feed good gut bacteria, which in turn improves insulin sensitivity.

The chicory group had 30% lower hemoglobin A1c levels compared to placebo, indicating better average blood sugar control. More research is underway.

Chicory is a member of the Asteraceae family of flowering plants, making it a relative of endive, dandelion, artichoke, and lettuce. Chicory flowers resemble wild dandelions but are usually light purple or blue color instead of yellow.

In the 1700s, a German merchant named Friedrich Christian Accum developed and marketed an imitation coffee bean made from roasted chicory root. It became popular across Europe as a coffee substitute and additive. Accum was the first person to successfully commercialize a coffee alternative, over 150 years before products like Postum first hit the market.

12. Chicory root extracts are used as natural food additives

Today, chicory root is processed on an industrial scale to extract inulin and other substances for use by the food industry. Inulin from chicory serves as a natural food additive to enhance taste, texture, and nutrition in products ranging from yogurt to protein bars. It also serves as a fiber supplement.
