Dandelion

Uses

Botanical names:
Taraxacum officinale

Parts Used & Where Grown

Closely related to chicory, dandelion is a common plant worldwide and the bane of those looking for the perfect lawn. The plant grows to a height of about 12 inches, producing spatula-like leaves and yellow flowers that bloom year-round. Upon maturation, the flower turns into the characteristic puffball containing seeds that are dispersed in the wind. Dandelion is grown commercially in the United States and Europe. The leaves and root are used in herbal supplements.

What Are Star Ratings?

This supplement has been used in connection with the following health conditions:

Used for Why
1 Star
Constipation
Refer to label instructions
The bitter compounds in dandelion leaves and root are also mild laxatives.

The unprocessed roots of fo-ti possess a mild laxative effect. The bitter compounds in dandelion leaves and root are also mild laxatives.
1 Star
Edema
Refer to label instructions
Dandelion leaves have diuretic effects that may be comparable to the prescription diuretics used to treat edema.

Herbs that stimulate the kidneys were traditionally used to reduce edema. Herbal diuretics do not work the same way that drugs do, thus it is unclear whether such herbs would be effective for this purpose. Goldenrod (Solidago cnadensis) is considered one of the strongest herbal diuretics. Animal studies show, at very high amounts (2 grams per 2.2 pounds of body weight), that dandelion leaves possess diuretic effects that may be comparable to the prescription diuretic furosemide (Lasix®). Human clinical trials have not been completed to confirm these results. Corn silk (Zea mays) has also long been used as a diuretic, though a human study did not find that it increased urine output. Thus, diuretic herbs are not yet well supported for use in reducing edema.
1 Star
Indigestion, Heartburn, and Low Stomach Acidity
Refer to label instructions
Dandelion acts as a digestive stimulant and may be helpful for indigestion.

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production. As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine, wormwood, gentian,dandelion, blessed thistle, yarrow, devil's claw, bitter orange, bitter melon, juniper, andrographis, prickly ash, and centaury.. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.
1 Star
Pregnancy and Postpartum Support
Refer to label instructions
Dandelion is a tonic herb, believed to strengthen or invigorate organ systems. A rich source of vitamins and minerals, it promotes urine and bile flow and helps with the common digestive complaints of pregnancy.

Many tonic herbs, which are believed to strengthen or invigorate organ systems or the entire body, can be taken safely every day during pregnancy. Examples include dandelion leaf and root, red raspberry leaf, and nettle. Dandelion leaf and root are rich sources of vitamins and minerals, including beta-carotene, calcium, potassium, and iron. Dandelion leaf is mildly diuretic (promotes urine flow); it also stimulates bile flow and helps with the common digestive complaints of pregnancy. Dandelion root is traditionally used to strengthen and invigorate the liver.

Traditional Use (May Not Be Supported by Scientific Studies)

Dandelion is commonly used as a food. The leaves are used in salads and teas, while the roots are sometimes 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 conditions as varied as eczema and cancer. As is the case today, dandelion leaves have also been used historically to treat water retention.

How It Works

Botanical names:
Taraxacum officinale

How It Works

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, 1/2–1 teaspoon (3–5 grams) of the dried root or 1–2 teaspoons (5–10 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, 1–2 teaspoons (4–10 grams) of dried leaves can be added to a 1 cup (250 ml) of boiling water and drunk as a decoction.8 Or, 1–2 teaspoons (5–10 ml) of fresh juice or 1/2–1 teaspoon (2–5 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.

Reduces Effectiveness

  • Ciprofloxacin

    In an animal study, administration of an extract of the whole plant dandelion (actually Taraxacum mongolicum, a close relative of the more common western dandelion, Taraxacum officinale) concomitantly with ciprofloxacin decreased absorption of the drug. The authors found this was due to the high mineral content of the dandelion herb. Until further information is available, ciprofloxacin should not be taken within two hours of any dandelion supplement including teas.

Side Effects

Dandelion leaf and root should not be used by people with gallstones without the supervision of a healthcare practitioner.9 People with an obstruction of the bile ducts should not take dandelion.

Animal studies have shown that dandelion can lower blood sugar levels. In a case report, a patient who was taking insulin for diabetes developed episodes of hypoglycemia after adding dandelion to her treatment regimen.10 People taking blood sugar-lowering drugs should therefore not take dandelion without the supervision of a doctor.

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 doctor before taking dandelion leaves. The milky latex in the stem and leaves of fresh dandelion may cause an allergic rash in some people.

Dandelion root contains approximately 40% inulin,11 a fiber widely distributed in fruits, vegetables and plants. Inulin is classified as a food ingredient (not as an additive) and is considered to be safe to eat.12 In fact, inulin is a significant part of the daily diet of most of the world's population.13 However, there is a report of a 39-year old man having a life-threatening allergic reaction after consuming high amounts of inulin from multiple sources.14 Allergy to inulin in this individual was confirmed by laboratory tests. Such sensitivities are exceedingly rare. Moreover, this man did not take dandelion. Nevertheless, people with a confirmed sensitivity to inulin should avoid dandelion.
