Exploring the Therapeutic Potential of Cichorium intybus: Phytochemistry, Pharmacology, and Applications

Chicory, a perennial herb in the family Asteraceae, is used for industrial, nutritional, and medicinal purposes. This plant is valued for its roots, leaves, and flowers, and was first grown in Europe. Its medicinal activities include antioxidant, anti-inflammatory, antibacterial, hepatoprotective, antidiabetic, and neuroprotective activities, and it is rich in phytochemical constituents such as inulin, phenolic compounds, alkaloids, flavonoids, and sesquiterpene lactones. The key prebiotic fibre, inulin, is generally found in chicory roots and promotes healthy bacteria, increasing digestion and balancing metabolic processes, which are invaluable to the body. Furthermore, its polyphenolic content, such as chlorogenic and caffeic acids, contributes to significant antioxidant and cardiovascular protective properties. New investigations indicate its possible functions in controlling weight, regulating immunity, and exerting anticancer activity. Despite its diverse health benefits, it should be used with care due to its adverse effects, which appear especially in individuals with allergies or gastrointestinal sensitivities. This review delves deeply into the phytochemical composition of chicory, its traditional use, and its pharmacological activities, and underscores the importance of the plant as a functional food and a phytomedicine. To boost its therapeutic potential, future research should focus on identifying its unknown bioactive compounds and their mechanisms of action.
