Stauntonia obovatifoliola

Dandelion (Taraxacum officinale) has been a familiar medicine and food in many parts of the world, and the preparations most consistently described in the literature are infusions and decoctions, with occasional use as tinctures and macerations. Among the Appalachian folk tradition of eastern North America, leaves, roots, and whole plants were infused as teas for “blood purifying,” coughs, and as diuretics, while roots were decocted for liver complaints (Vargo-Gogt, 1995). In traditional Eastern European practice, as reflected in European herbal materia medica, roots and aerial parts were taken as teas to support digestion and liver function, with the roots also given as decoctions for gall-bladder complaints (Bown, 1995). Farther east, in traditional Chinese medicine recorded by the Pharmacopoeia of the People’s Republic of China, the flower heads have been used as teas (infusions) to brighten the eyes and relieve headaches (Chinese Pharmacopoeia, 2020). While leaves and flowers are also eaten as vegetables, the uses most often linked to herbal practice rely on teas or decoctions rather than whole-food preparations.

A straightforward way to prepare the familiar dandelion leaf tea is a mild infusion. For one cup, place 2–4 g of dried dandelion leaves in a teapot or infuser, pour 200–250 mL of just-boiled water, cover, and steep for 5–10 minutes. Strain and drink 1–2 cups daily. As a general note for safety, dandelion is not recommended for people with bile duct obstruction, active gallbladder disease, or known allergy to Asteraceae; the sesquiterpene lactones can irritate the stomach in sensitive individuals and, as always with diuretics, individuals on lithium or potassium-depleting medications should use with medical guidance.

The plant’s traditional profile is reflected in its established constituents. The latex-rich roots contain taraxasterol, taraxerol, and other triterpenes; leaves provide sesquiterpene lactones such as taraxinic acid β-glucoside and guaianolide lactones, plus flavonoids, phenolic acids, and vitamins including vitamin C (Phytotherapy Research, 2020; Natural Product Communications, 2022). These compounds align with the long-noted diuretic, cholagogue, and bitter tonic actions that have led to infusions and decoctions for urinary and hepatic support.

Modern relevance remains strong. Dandelion leaf teas and root decoctions are still sold as herbal teas and appear in clinical research investigating diuretic and liver-supportive effects, while the flowers persist in proprietary products for eye comfort and traditional use in China continues alongside their use in foods and wines (Food & Chemical Toxicology, 2017; Journal of Ethnopharmacology, 2016).
