Dandelion root is one of the most effective detoxifying herbs. Working principally on the liver and gallbladder to help remove waste products, it also stimulates the kidneys to remove toxins in the urine. A well-balanced remedy, it encourages steady elimination of toxins due to infection or pollution. It is beneficial for many conditions, including constipation, skin problems such as acne, eczema, and psoriasis, and arthritic conditions, including osteoarthritis, and gout.

Brief History

Taraxacum officinalis

Introduced into European medicine by the Arabs who were writing about it as early as the 10th century. Taraxacum comes from the Greek taraxis, “to move or disturb”, but the name originally may have come from the Persian name for the herb, tarashqun. The shape of the leaves gives the French name, dents de lion, or “teeth of the lion.” Another French name is pis en lit or “pee in bed” from its diuretic effects.


Dandelion grows wild in most parts of the world and is cultivated in Germany and France. It is propagated from seed in spring. The young leaves are picked in spring for tonic salads and later as a medicine. The root of 2-year-old plants is unearthed in autumn.

Primary Uses

Constipation, haemorrhoids, and indigestion.

German research has shown that dandelion root is a mild bitter, or appetite stimulant. Bitters of all types activate a reflex that increases the secretion of digestive juices by the lining of the stomach. Dandelion root has a significant cleansing effect on the liver by stimulating the production of bile, which ultimately results in increased transport of a variety of potentially noxious compounds to the stool. Increasing the release of bile also relieves constipation without causing diarrhoea and stops spasms of the bile duct.

Liver problems and gallstones

The bitter principles in dandelion increase bile production and bile flow in the liver. This makes it useful for people with sluggish liver function due to alcohol abuse or poor diet. It is restorative to the liver and helps reduce the risk of developing gallstones, but you should avoid it if you already have gallstones, since increasing the flow of bile could increase pressure against the stones.


European herbalists frequently prescribe dandelion tinctures as a weight-loss aid. Dandelion reduces water weight through its diuretic effect. Dandelion may increase bile flow to improve fat metabolism in the body. In one laboratory study, animals that were given daily doses of dandelion extract for a month lost up to 30 percent of their body mass.

Clinical Research

In a randomised, prospective study, treatment of ureteric calculi with either spasmoanalgesic therapy or an herbal preparation was compared. The preparation contained dandelion root and leaf, golden rod, Rubia tinaorum, Ammi visnaga, and a small amount of escin (a constituent of horse chestnut seed). No significant difference was observed concerning the transit times of the stones between the two groups, but side effects and treatment costs were less in the herbal therapy group. The strength of the herbal extracts in these capsules was not defined.

In a double-blind, placebo-controlled, randomised, clinical trial, 57 women with recurrent cystitis received either herbal treatment (standardised uva ursi extract and dandelion leaf and root extract) or placebo. Treatment for one month significantly reduced the recurrence of cystitis during the 1-year follow-up period, with no incidence of cystitis in the herbal group and a 23% occurrence in the placebo group. No side effects were reported.The dose of the individual herbs was not specified.

In Germany, the Commission E supports using Dandelion root with leaf is recommended to treat disturbed bile flow, loss of appetite, and dyspepsia. This combination is also used to stimulate diuresis.

ESCOP recommends dandelion root for restoring hepatic and biliary function, dyspepsia, and loss of appetite.
