Dandelion (Taraxacum officinale) — Lion's Tooth, Blowball, Pissenlit
Materia Medica
Family: Asteraceae
Common names: Dandelion, lion's tooth, blowball, pissenlit
Part used: Root, leaf, and flower
Growth habit: Perennial herb with basal rosette and taproot
Primary tradition: European folk, Eclectic, and Chinese materia medica
Actions & Energetics
Cooling and bitter, with drying qualities in the leaf. Root preparations are regarded as bitter digestive, hepatic, and cholagogue. Leaf is classically diuretic and rich in potassium. Both are traditionally classified as alterative and nutritive.
Botanical Description
A basal rosette of deeply lobed or toothed leaves arises from a fleshy taproot. Hollow, leafless scapes support solitary yellow flower heads composed of numerous ligulate florets. After flowering, the head transforms into a spherical seed clock of achenes with white pappus. The plant thrives in disturbed soils, lawns, and meadows.
Name Confusion & Look-Alikes
True dandelion is distinct from other yellow-flowered composites such as hawkweeds or sow-thistles by its hollow scape and characteristic seed clock. Correct identification of the basal leaves and root is important for medicinal use.
Traditional Indications
European folk and Eclectic traditions employed the root for sluggish digestion, loss of appetite, and support of the liver and gallbladder. The leaf was used for fluid retention and urinary comfort. Young leaves appear in spring salads; roasted root has served as a coffee substitute; flowers are made into wine and syrup.
Preparations & Dosage
Root decoction or cold infusion: traditionally 2–8 g dried root daily. Leaf infusion: 4–10 g. Tinctures of root or leaf are common. Culinary use of young leaves and roasted root is long-established. Commission E and EMA traditional monographs list the root for dyspepsia and the leaf as a diuretic.
Classical Formulations
Dandelion appears in numerous European and Eclectic formulas for digestive and hepatic support. It is also used in traditional Chinese formulas with related species.
Constituents
Sesquiterpene lactones, flavonoids, phenolic acids, inulin (especially in the root), potassium, and triterpenes. Inulin content varies with season. The bitter lactones are primarily responsible for digestive stimulation.
Modern Research
Preclinical studies document antioxidant, anti-inflammatory, and cholagogue activity. A small human pilot with fresh leaf extract showed increased urinary frequency. Root preparations have been examined for digestive and metabolic effects, though large controlled trials remain limited. Food use is well documented and classified GRAS.
Adverse Effects
Generally well tolerated. The bitter taste may cause mild digestive stimulation. Allergy is possible in individuals sensitive to Asteraceae plants.
Interactions & Contraindications
The diuretic action of the leaf may theoretically interact with diuretic medications. No well-established serious interactions are documented for traditional doses. Avoid in known Asteraceae allergy.
Pregnancy & Breastfeeding
Culinary amounts are generally regarded as safe. Concentrated medicinal use during pregnancy lacks sufficient safety data.
Habitat & Cultivation
Cosmopolitan perennial native to Eurasia and naturalized across temperate regions worldwide. Thrives in disturbed soils, lawns, and meadows. Prefers full sun and well-drained soil.
Propagation
Easily propagated by seed. The plant self-seeds readily and is often considered a weed in cultivated areas.
Harvesting & Drying
Young spring leaves are harvested for culinary use. Roots are typically harvested in autumn or early spring when inulin content is higher. Flowers are collected when fully open. Dry thoroughly with good airflow.
Food Use
Young leaves are used in salads and cooked greens. Roasted root serves as a coffee substitute. Flowers are used in wine, syrup, and fritters. All parts are edible when properly prepared.
History, Folklore & Spiritual Use
The English name derives from the French dent-de-lion, referring to the serrated leaves. European spring-tonic traditions treat it as a blood cleanser after winter. Children have long blown the seed clocks to make wishes. The plant remains one of the most widely recognized wild edible and medicinal herbs in temperate climates.
