Chicory is a very beautiful plant whose seeds, roots, dried flowers and leaves are used in medicine, cooking and herbal medicine. It has a lot of nutrients, and it can also be useful for heart health, normalization of digestion and weight.
Crushed and roasted chicory root makes a drink that tastes and colors like coffee. Presumably it was used as an alternative to this drink back in the 1800s, when there was a shortage of coffee beans in France.
