Taraxacum mongolicum, commonly known as Mongolian dandelion or Chinese dandelion, is a species of flowering plant in the family Asteraceae. It is a perennial herb native to temperate regions of East Asia, including China, Mongolia, Korea, Japan, Taiwan, and parts of eastern Russia. The plant typically grows between 8 and 25 cm tall, producing a basal rosette of lobed green leaves and solitary yellow flower heads on hollow, hairy stems. It is commonly found in disturbed habitats such as grasslands, roadsides, and cultivated areas, and reproduces primarily through agamospermy.
The species has been traditionally used in East Asian medicine, where it has been applied in the treatment of inflammatory and infectious conditions. Modern studies have investigated its potential pharmacological properties, including antimicrobial, anti-inflammatory, and cytotoxic effects. It is also being researched as a possible phytogenic feed additive in livestock, particularly poultry, due to its influence on gut health and immune response. The plant contains a variety of bioactive compounds such as flavonoids, phenolic acids, and polysaccharides.
Taraxacum mongolicum has been introduced to other regions, including North America, where it has become naturalized in some areas. It was first formally described by Austrian botanist Heinrich von Handel-Mazzetti and has since been referenced under several botanical synonyms.
Description Taraxacum mongolicum is a small perennial herb, typically growing to a height of 8–25 cm. The root is slightly conical, often bent, measuring 4–10 cm in length, with a brown surface and a shriveled root head covered in brown or yellowish-white woolly hairs. The stem is shortened but visible above the ground.
The basal leaves (those growing at the base of the plant) form a rosette and are mid-green in color. They are oblanceolate to oblong-lanceolate (inverted spoon-shaped to narrow and tapering) in shape, ranging from 6–15 cm long and 1–2.5 cm wide. The leaves are commonly divided into 3–5 pairs of lateral lobes (side divisions), with margins that may be entire (smooth-edged), sparsely toothed, or pinnatifid (deeply lobed but not all the way to the center). The terminal lobe (at the tip) is usually large, triangular or broadly triangular, with a rounded or blunt tip. The base of each leaf tapers into a short petiole (leaf stalk). Leaf surfaces are mostly smooth to slightly hairy, and may sometimes show dark purple spots. The petioles and main veins are often tinged red and may bear sparse arachnoid (cobweb-like) white hairs.
The plant produces solitary flowering scapes (leafless flower stalks) that emerge from the leaf axils (where the leaf meets the stem), measuring 10–25 cm in height and roughly equal to or slightly taller than the leaves. These scapes are brownish-green and densely covered in fine hairs below the flower head. The flower head, or capitulum, is 3–4 cm wide, consisting of numerous yellow ligulate florets (strap-shaped flowers). The outer florets are striped grayish purple, while the inner ones have purple-tipped margins. The involucral bracts (modified leaves around the flower base, also called phyllaries) are ovate-lanceolate to lanceolate (egg to spear shaped), with the outer bracts often tinged with pink and bearing fine hairs. The anthers are dark green and the stigmas are pale green.
Fruits are obovate-lanceolate to oblong achenes (dry, single-seeded fruits), brown to grayish in color, and measure approximately 4.2–4.6 mm long. The surface is rough and ends in a cone-shaped apex, from which extends a slender beak 7–10 mm long that supports a yellowish pappus (a ring of fine hairs that aids wind dispersal) about 6 mm long. Flowering occurs mainly from spring to early autumn, with peak blooming from March to September. The species reproduces asexually through agamospermy (seed production without fertilization). Taxonomy Taraxacum mongolicum was first described in 1907 by Heinrich von Handel-Mazzetti in Monographia Taraxacum. It belongs to the genus Taraxacum within the family Asteraceae. The species has several recorded synonyms, including Taraxacum argute-denticulatum, T. formosanum, and T. hangchouense. It is considered distinct from the more widespread Taraxacum officinale, though the two share similar morphological features. The evolutionary relationships between similar species in the genus Taraxacum was analysed in a 2024 article in Industrial Crops and Products. The phylogenetic tree produced by comparing chloroplast genes is shown below.
Distribution Taraxacum mongolicum is native to Europe and Asia, where it naturally occurs in grassland ecosystems and other open, disturbed habitats. It is well-adapted to a variety of soil types and climates, particularly in temperate regions. In its native range, it has long been a common species in uplands, fields, and along roadsides.
The species was introduced to North America as a food crop and has since become widely naturalized across the continent. It now occurs throughout North America, including in both residential and agricultural landscapes. In addition to its spread across North America, T. mongolicum has also established populations in Southern Africa, South America, New Zealand, Australia, and India. It is now broadly distributed in subtropical and temperate zones worldwide. It is known to be heat and cold tolerant.
Medical usage The leaves of Taraxacum mongolicum were first documented in 659 AD in the Xinxiu Bencao, an early Chinese materia medica. In traditional East Asian medicine, the species is considered to possess antibacterial and anti-inflammatory properties and has historically been employed in the treatment of mastitis, breast abscesses, and mammary gland hyperplasia.
Pharmacokinetic studies have investigated potential interactions between T. mongolicum and pharmaceutical agents. In one animal study, co-administration of an aqueous extract of the plant with the antibiotic ciprofloxacin significantly reduced the drug's maximum plasma concentration—by approximately 73% in rats. Additionally, the extract altered the drug's distribution and elimination profile, increasing its apparent volume of distribution and terminal half-life. However, overall bioavailability, measured by the area under the plasma concentration–time curve (AUC), remained largely unchanged. These results indicate that T. mongolicum may influence the pharmacokinetics of certain medications and should be used with caution in clinical contexts involving concurrent drug therapy.
A 2020 study investigated the effects of T. mongolicum extract in a mouse model of mastitis caused by the bacterium Staphylococcus aureus. Mice treated with the extract showed significantly lower levels of inflammatory molecules in the mammary tissue, including tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β), which are key indicators of inflammation. The extract also reduced the activity of myeloperoxidase (MPO), an enzyme released by immune cells during inflammation, which serves as another marker of immune response.
Microscopic examination of tissue samples revealed that the extract reduced swelling, cell damage, and necrosis in the affected glands. On a molecular level, the anti-inflammatory effects were linked to decreased activation of the NF-κB and MAPK signaling pathways, which are involved in the body's immune response. The extract also lowered the expression of Toll-like receptor 2 (TLR2), a protein that helps immune cells recognize bacterial infections. By interfering with these pathways, T. mongolicum appeared to reduce inflammation and protect tissues from further damage, suggesting potential for therapeutic use in infections that involve excessive inflammation, such as mastitis.
Oncology Modern pharmacological research has provided experimental evidence supporting T. Mongolicum's anticancer potential. Several in vitro studies have demonstrated cytotoxic effects of T. mongolicum extracts, particularly against breast cancer cell lines. One study tested aqueous (water-based) extracts on three human breast cancer cell lines—MDA-MB-231 (a triple-negative type that lacks hormone receptors), MCF-7 (estrogen receptor-positive [ER+], progesterone receptor-positive [PR+], and HER2-negative), and ZR-75-1 (ER+, PR partially positive or negative, and HER2−). The extract significantly reduced cell viability, with the strongest effects observed in the triple-negative MDA-MB-231 cells. It induced apoptosis (programmed cell death), disrupted mitochondrial membrane potential (which affects the cell's energy production), suppressed cell proliferation and colony formation, and lowered the rate of oxygen consumption, suggesting the mitochondria were no longer functioning properly.
Another study focused specifically on triple-negative breast cancer (TNBC), an aggressive subtype with limited treatment options. It found that T. mongolicum extract caused the cancer cells to stop dividing at the G2/M phase of the cell cycle—a checkpoint just before cells divide—and triggered apoptosis. This cell death was linked to stress in the endoplasmic reticulum (ER), a part of the cell involved in protein folding. The extract activated a specific stress pathway known as the PERK/p-eIF2α/ATF4/CHOP axis. It increased the activity of genes related to ER stress, including ATF4, ATF6, XBP1s, GRP78, and CHOP, and boosted levels of proteins involved in apoptosis, such as cleaved caspase-3 and PARP. Further experiments using a caspase inhibitor (Z-VAD-FMK) and small interfering RNA (siRNA) targeting CHOP confirmed that the cell death was dependent on CHOP, a key protein in the stress response pathway.
In hormone-responsive breast cancer cell lines, T. mongolicum reduced the levels of regulatory proteins involved in cell cycle progression, such as cyclin D1 and p21, and selectively increased the expression of p53, a well-known tumor suppressor protein. Unlike some related plant species, T. mongolicum did not trigger ribotoxic stress (a harmful response involving damage to the cell's ribosomes), suggesting a distinct and possibly safer mechanism of action.
In addition to killing cancer cells directly, T. mongolicum influenced the immune environment around tumors in TNBC. In lab experiments, the extract inhibited the growth, movement, and spread of TNBC cells when tumor-associated macrophages (TAMs)—a type of immune cell often found in tumors—were present. The extract suppressed the IL-10/STAT3/PD-L1 signaling pathway, which normally helps tumors evade immune attack. It also shifted macrophages from the M2 type (which supports tumor growth) to the M1 type (which fights tumors), suggesting that T. mongolicum may help stimulate the body's immune response against cancer.
Veterinary A 2022 study found that adding Taraxacum mongolicum to the diet of broiler chickens improved their growth, boosted the activity of genes related to intestinal barrier function (which helps protect against pathogens), reduced markers of inflammation, and changed the composition of gut bacteria by increasing beneficial species and reducing potentially harmful ones. These results suggest that T. mongolicum and related dandelion species may serve as natural alternatives to antibiotics in poultry farming.
