Chicory: Benefits, Dosage, Contraindications

Updated on

Chicory is a perennial plant belonging to the Asteraceae family. Native to Europe and Asia, it commonly grows along paths and in uncultivated areas. Mentioned in the Ebers Papyrus, dating back to 4000 BC, chicory has a long history of medicinal and culinary use. Its name 'intybus' comes from Syrian, meaning 'hollow stem', like a flute. During the first year, it forms a rosette of soft leaves, then, in the second year, it raises an upright stem and blooms from July to September, displaying magnificent azure blue flowers often grouped in pairs. Chicory is appreciated for its medicinal properties and culinary uses. Saint Hildegard recommended it for indigestion and treating wounds and boils externally. The plant's juice was once used against poisoning. The whole plant is known for its tonic, stomachic, depurative, diuretic, laxative, cholagogue, and febrifuge properties. It promotes the elimination of excess bile and cleanses the liver, spleen, and kidneys. The aerial parts and roots of chicory are used. They contain inulin (10 to 15%), sesquiterpene lactones, phenolic acids (chlorogenic and caffeic acids...), phytosterols, and tannins. Chicory is also rich in vitamins C, B, P, and K. For centuries, chicory has been consumed as a salad. It is considered an excellent remedy-food as it strengthens the stomach. Besides its culinary uses, chicory is also cultivated for chicory coffee production, a caffeine-free alternative to traditional coffee. Today, chicory is used for digestive disorders such as bloating, slow digestion, belching, flatulence, to ease urinary and digestive elimination functions, as an aid in slimming diets, and to promote renal water elimination.

Metabolic syndrome

A small clinical study showed that the consumption of chicory seeds, 9 g infused in hot water daily for 12 weeks, can lower body mass index (BMI) in patients with non-alcoholic fatty liver disease. Although chicory seeds did not significantly affect other liver enzymes or plasma lipid levels compared to a placebo, they showed some promise when combined with 3 g of turmeric per day, reducing serum alkaline phosphatase enzyme.

Traditionally, chicory has been used to treat various digestive disorders, including dyspepsia accompanied by liver congestion. Thanks to its cholagogue properties, chicory promotes the elimination of excess bile, thus helping relieve the symptoms of heaviness associated with poor liver function.

Animal and in vitro research indicates that chicory extracts have antidiabetic effects. Inulin-type fructans from chicory root may influence the production of peptides like incretins, which are crucial in appetite regulation and diabetes and obesity management. Furthermore, in diabetic rats, chicory extract increases glucose-induced insulin secretion and protects against damage to pancreatic beta cells, potentially playing a role in diabetes management.

Chicory is renowned for its beneficial effects on digestion, notably due to its ability to act as a prebiotic. Chicory fructans, such as oligofructose and inulin, promote the growth of bifidobacteria in the colon, beneficial bacteria for gut health. Additionally, chicory root may have a mild laxative effect and stimulate bile production, aiding digestion. Animal studies also suggest that chicory root extract may help prevent ulcer development and possess liver-protective properties.
