Historical or traditional use: Dandelion is commonly used as a food. The leaves are used in salads and teas, while the roots are often used as a coffee substitute. Dandelion leaves and roots have been used for hundreds of years to treat liver, gallbladder, kidney, and joint problems. In some traditions, dandelion is considered a blood purifier and is used for ailments as varied as eczema and cancer. As is the case today, dandelion has also been used historically to treat poor digestion, water retention, and diseases of the liver, including hepatitis.

Root: bitter glycosides, tannins, triterpenes, sterols, volatile oil, choline, asparagin, inulin.

Active constituents: The principal constituents responsible for dandelionÕs effect 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 very 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 The leaves are a rich source of potassium, which is interesting since the leaves are used for their diuretic action. This may make dandelion the only naturally occurring potassium-sparing diuretic, although its diuretic action is likely different from pharmaceuticals.

At high doses, the leaves have been shown to possess diuretic effects comparable to the prescription diuretic frusemide (Lasix).3 Since clinical data in humans is sparse, it is advisable to seek the guidance of a physician trained in herbal medicine before using dandelion leaves for water retention.

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 This makes them a particularly useful tonic for persons with sluggish liver function due to alcohol abuse or poor diet. The increase in bile flow will help improve fat (including cholesterol) metabolism in the body.

How much should I take? As a general liver/gallbladder tonic and to stimulate digestion, 3-5 grams of the dried root or 5-10 ml of a tincture made from the root can be used three times per day. Some experts recommend the alcohol-based tincture because the bitter principles are more soluble in alcohol.6

As a mild diuretic or appetite stimulant, 4-10 grams of dried leaves can be added to a 250 ml (1 cup) of boiling water and drunk as a decoction; or 5-10 ml of fresh juice from the leaves or 2-5 ml of tincture made from the leaves can be used, three times per day.

Legends, Myths and Stories

Potassium is often flushed from the body when synthetic diuretics are taken. But dandelion has an abundance of potassium to off-set this problem.

The feathery seed balls of the dandelion were once used by young girls to determine if their true loves were really true. They would blow on the dandelion fuzzy ball 3 times; if at least one of the fuzzy seeds remained, it was taken as an omen that her sweetheart was thinking about her.

Culpeper says dandelion is “vulgarly called Piss-a-Beds.”

Since the 7th century, the Chinese have known about the antibacterial properties of the juice of the dandelion. Researchers recently discovered that dandelion may protect against cirrhosis of the liver. In Europe, the dandelion first appears as being used medicinally in 1485. The name dandelion was invented by a 15th century surgeon, who compared the shape of the leaves to a lion’s tooth, or dens leonis. Old timers called dandelion the “King of Weeds.”

A French authority claimed that the flowers and stems of dandelion are “enormously rich in estrogen.” Dandelion was brought to the New World by the early colonists. They used the whole plant. The flowers made wine, the leaves made salads, the stems and roots dried and used medicinally. According to stories, dandelion never grows where there are no human inhabitants. The early pioneers found no trace of them in western America. After a few years, up sprang a dandelion head and soon there were millions of them. Native Americans learned to love them and would walk miles to gather them if they could not be found locally.

Dandelion coffee is made of high quality roots, now grown on specialized farms. Proper harvesting, drying and skillful roasting methods give dandelion a remarkable roasted flavor that many people readily accept as a coffee substitute. Dandelion coffee has been found to be of benefit to dyspeptic people, who cannot tolerate real coffee. The roasted root has no caffeine, so drink it as often as desired, even as a night cap.

Roasted dandelion root has almost a magical effect upon milk. Steep 1 heaping tsp. of roasted root in 1 cup of hot, not boiling, milk, for 5 to 10 minutes and strain. Sweeten if desired. The resultant liquid tastes like rich cream. Of course with fewer calories. Try on breakfast cereals, it is great. Also, try this dandelion milk in recipes that call for milk as an ingredient.

Add 1/4 tsp. powdered licorice to give dandelion milk a pleasant tang.

Are there any side effects or interactions? Dandelion leaf and root should be used with caution by persons with gallstones. If there is an obstruction of the bile ducts, then dandelion should be avoided altogether. In cases of stomach ulcer or gastritis, dandelion should be used cautiously, as it may cause overproduction of stomach acid. Those experiencing fluid or water retention should consult a nutritionally oriented doctor before taking dandelion leaves. People taking the leaves should be sure their doctor monitors potassium levels. The milky latex in the stem and leaves of fresh dandelion may cause an allergic rash in some individuals.
