The primary constituents responsible for dandelion’s action on the digestive system and liver are the bitter principles. Previously referred to as taraxacin, these constituents are sesquiterpene lactones of the eudesmanolide and germacranolide type, and are unique to dandelion.1 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.2
An animal study found that at high amounts (2 grams per 2.2 pounds [1 kg] of body weight), the leaves possess diuretic effects comparable to the prescription diuretic furosemide (Lasix).3 However, to date, these results have not been demonstrated in human clinical trials. Since edema, or water retention, may be a sign of a more serious disease, people should seek the guidance of a physician before using dandelion leaves for either of these conditions.
The bitter compounds in the leaves and root help stimulate digestion and are mild laxatives.4 These bitter principles also increase bile production in the gallbladder and bile flow from the liver.5 For this reason dandelion is recommended by some herbalists for people with sluggish liver function due to alcohol abuse or poor diet. The increase in bile flow may help improve fat (including cholesterol) metabolism in the body.
How to Use It
As a general liver/gallbladder tonic and to stimulate digestion, 1/21 teaspoon (35 grams) of the dried root or 12 teaspoons (510 ml) of a tincture made from the root can be used three times per day.6 Some experts recommend the alcohol-based tincture because the bitter principles are more soluble in alcohol.7
As a mild diuretic or appetite stimulant, 12 teaspoons (410 grams) of dried leaves can be added to a 1 cup (250 ml) of boiling water and drunk as a decoction.8 Or, 12 teaspoons (510 ml) of fresh juice or 1/21 teaspoon (25 ml) of tincture made from the leaves can be used three times per day. Fresh dandelion leaves can be eaten as part of a salad.
