Dandelion is a common plant that is closely related to chicory.
The leaves and roots are used in herbal supplements. Dandelion is used as a food in many parts of the world. Its leaves are sometimes used in salads and teas, while its roots are often used as a coffee substitute. Historically, dandelion has been used as a blood purifier and a treatment for disease of the liver, including hepatitis. Clinical research has found that the compounds that make dandelion leaves so bitter help stimulate digestion and increase bile production in the gallbladder and bile flow from the liver.
