Taraxacum officinale
Free herbal dosage calculator — adult & child doses by weight.
Dandelion is a widely distributed plant considered a weed by many but valued as a potent medicinal herb for centuries. Every part of the plant is edible and medicinal. The leaves are a natural diuretic rich in potassium, while the root supports liver and digestive health.
Dandelion (Taraxacum officinale) is a ubiquitous plant with traditional use for liver support, digestion, and as a diuretic. The root and leaf have different profiles: root is cholagogue and hepatoprotective; leaf is diuretic. While widely used, clinical evidence is limited (Level C). The diuretic effect is comparable to furosemide in animal studies but human data is sparse. It is nutrient-dense (vitamins A, C, K; minerals) and generally very safe.
Root contains sesquiterpene lactones (taraxacin), triterpenes (taraxasterol), inulin (prebiotic), and phenolic acids. Leaf contains high potassium and flavonoids. Cholagogue effects stimulate bile flow (choleretic and cholagogue). Hepatoprotective effects may involve antioxidant and anti-inflammatory activity. Diuretic effects are via kidney Na+/K+ pump inhibition. Inulin supports gut microbiome. The high potassium content distinguishes it from conventional diuretics (which cause K+ loss). Some constituents demonstrate anti-inflammatory and antimicrobial properties.

Dandelion leaves act as a natural diuretic by increasing urine production through stimulation of kidney function. Unlike pharmaceutical diuretics, dandelion naturally contains high levels of potassium, which helps replace what is typically lost through increased urination. The sesquiterpene lactones and flavonoids in dandelion are believed to be responsible for this diuretic effect. Evidence level B indicates good traditional and preliminary clinical evidence for this mechanism.
Yes, dandelion may interact with several medications. As a diuretic, it may enhance the effects of prescription diuretics (water pills), increasing the risk of dehydration and electrolyte imbalances. Dandelion may interact with lithium by affecting its clearance through increased urination. The root's effects on liver enzymes may alter how the liver metabolizes certain drugs. Always consult a healthcare provider before combining dandelion with prescription medications.
The typical adult dosage for dandelion root is 2-8 grams of dried root taken three times daily. For fresh leaves, 4-10 grams daily is standard. Tea preparations typically recommend 1-2 cups daily. Dandelion can be consumed as a decoction, tincture, capsule, or fresh in salads. Start with lower doses and increase gradually to assess individual tolerance. Dosage may vary based on the specific health concern being addressed.
Dandelion is considered unsafe during pregnancy and should be avoided. While dandelion is a natural herb, its diuretic properties and effects on liver and digestive function may not be appropriate during pregnancy. There is insufficient safety data for pregnant women, warranting caution. Breastfeeding women should also consult a healthcare provider before using dandelion supplements. Traditional use does not establish safety during pregnancy.
Dandelion root is primarily used as a liver tonic and digestive bitter. It supports liver health by stimulating bile production and flow, which aids digestion and detoxification. The root contains inulin, a prebiotic fiber that supports healthy gut bacteria. Dandelion root is also traditionally used as a blood purifier and for kidney support. Evidence level B indicates promising traditional and preliminary clinical evidence for these uses.
Dandelion should be avoided by individuals with bile duct obstruction, gallstones, or active gallbladder inflammation, as stimulating bile flow could worsen these conditions. Those with allergies to plants in the Asteraceae family (ragweed, daisies, marigolds) should avoid dandelion due to potential allergic reactions. Pregnant women should not use dandelion. People taking diuretics, lithium, or medications metabolized by the liver should consult a healthcare provider first.
