Dandelion is used as a bitter tonic in atonic dyspepsia, and as a mild laxative in habitual constipation. When the stomach is irritated and where active treatment would be injurious, the decoction or extract of Dandelion administered three or four times a day, will often prove a valuable remedy. It has a good effect in increasing the appetite and promoting digestion. The leaves are used in salads and teas, while the roots are often used as a coffee substitute. The principal constituents responsible for dandelion s action on the digestive system and liver are sesquiterpene lactones that are unique to dandelion.
Dandelion is also a rich source of vitamins and minerals.
The leaves have a high content of vitamin A as well as moderate amounts of vitamin D, vitamin C, various B vitamins, iron, silicon, magnesium, zinc, and manganese. The bitter compounds in the leaves and root help stimulate digestion and are mild laxatives. These bitter principles also increase bile production in the gallbladder and bile flow from the liver. For this reason dandelion is recommended by some herbalists for persons with sluggish liver function due to alcohol abuse or poor diet. It is a general stimulant to the system, but especially to the urinary organs, and is chiefly used in kidney and liver disorders.
