Background Taraxacum officinale (L.) Weber (Asteraceae) has been extensively employed as a diuretic in traditional folk medicine and in modern phytotherapy in Europe, Asia, and the Americas without prior clinical trial substantiation. Objectives In this pilot study, a high-quality fresh leaf hydroethanolic extract of the medicinal plant T. officinale (dandelion) was ingested by volunteers to investigate whether an increased urinary frequency and volume would result. Design Volume of urinary output and fluid intake were recorded by subjects. Baseline values for urinary frequency and excretion ratio (urination volume:fluid intake) were established 2 days prior to dandelion dosing (8 mL TID) and monitored throughout a 1-day dosing period and 24 hours postdosing. Results For the entire population (n = 17) there was a significant (p Conclusions Based on these first human data, T. officinale ethanolic extract shows promise as a diuretic in humans. Further studies are needed to establish the value of this herb for induction of diuresis in human subjects.
Taraxacum refers to the genus Taraxacum , which has a long history of use as a medicinal plant and is widely distributed around the world. There are over 2500 species in the genus Taraxacum recorded as medicinal plants in China, Central Asia, Europe, and the Americas. It has traditionally been used for detoxification, diuresis, liver protection, the treatment of various inflammations, antimicrobial properties, and so on. We used the most typically reported Taraxacum officinale as an example and assembled its chemical makeup, including sesquiterpene, triterpene, steroids, flavone, sugar and its derivatives, phenolic acids, fatty acids, and other compounds, which are also the material basis for its pharmacological effects. Pharmacological investigations have revealed that Taraxacum crude extracts and chemical compounds contain antimicrobial infection, anti-inflammatory, antitumor, anti-oxidative, liver protective, and blood sugar and blood lipid management properties. These findings adequately confirm the previously described traditional uses and aid in explaining its therapeutic applications.
Taraxaci herba , as a traditional Chinese medicine, is the name of the Taraxacum genus in the Asteraceae family. Documented in the Tang Herbal Medicine (Tang Dynasty, AD 657-659), its medicinal properties cover a wide range of applications such as acute mastitis, lung abscess, conjunctival congestion, sore throat, damp-heat jaundice, and vision improvement. In the Chinese Pharmacopoeia (Edition 2020), more than 40 kinds of China-patented drugs containing Taraxaci herba were recorded. This review explores the evolving scientific understanding of Taraxaci herba , covering facets of ethnopharmacology, botany, phytochemistry, pharmacology, artificial cultivation, and quality control. In particular, the chemical constituents and pharmacological research are reviewed. Taraxaci herba has been certified as a traditional medicine plant, and its flavonoids, phenolic acids, and terpenoids have been identified and separated, which include Chicoric acid, taraxasterol, Taraxasteryl acetate, Chlorogenic acid, isorhamnetin, and luteolin; they are responsible for anti-inflammatory, antioxidant, antibacterial, anti-tumor, and anti-cancer activities. These findings validate the traditional uses of Taraxaci herba and lay the groundwork for further scientific exploration. The sources used in this study include Web of Science, Pubmed, the CNKI site, classic monographs, the Chinese Pharmacopoeia, the Chinese Medicine Dictionary, and doctoral and master's theses.

Mechanistic basis
This use is associated with the plant's diuretic action. Further evidence for that pharmacology:
Dandelion (Taraxacum officinale Weber) was evaluated for diuretic activity. Extracts and purified fractions isolated from autumn-collected roots were examined using saline - loaded mice. No significant increases in urine volume and sodium excretion were produced by any extracts. Dandelion leaves and roots collected from different locations in Ireland were also examined over a period of eight months (October-May) for total ash and major mineral contents. No significant variation or major trends in any of the parameters were found. Average leaf ash was 14.50% w/w and root ash 7.50% w/w; leaf ash was always.twice the value of root ash when obtained from the same plants. Mean leaf K+ content was 4.51% w/w and for roots 2.45% w/w. The K+ content of both leaves and roots always represented one third of the total ash. Mean Na+ contents for leaves were 0.49% w/w and roots 0.33% w/w; while values for Ca2+ were 0.88% w/w for leaves and 0.33% w/w for roots. The high K+ content of dandelion is considered to be the agent responsible for any diuretic activity.
