Medicinal Properties
Dandelion is renowned for its therapeutic effects on a variety of health conditions. It has been traditionally used to treat dyspepsia, bile duct disorders, spleen and liver complaints, and inflammatory diseases. The plant’s flowers, leaves, and roots are all utilized in different forms of phytomedicine to harness these benefits.
Immunostimulatory Effects
Recent research has highlighted the immunostimulatory properties of dandelion, particularly its flower extract. A study on rainbow trout (Oncorhynchus mykiss) demonstrated that dietary supplementation with dandelion flower extract (DFE) significantly enhances both skin mucosal and humoral immunity. The study involved feeding fingerlings with varying levels of DFE and observing the effects on immune-related parameters and disease resistance1.
Study Findings
The study found that total leukocyte and lymphocyte counts were significantly higher in groups treated with DFE compared to the control group. Additionally, components such as immunoglobulin M, total protein, and lysozyme were elevated in fish treated with 3 g/kg of DFE. The enzymatic activities of skin mucus samples were also significantly higher in the DFE-treated fish, indicating improved immune function1.
Gene Expression and Disease Resistance
The transcription levels of immune-related genes, including interleukin-1β and interleukin-6, were up-regulated in fish fed with higher doses of DFE. Furthermore, interleukin-8 and lysozyme gene expression levels were elevated in the 3 g/kg DFE group. This enhanced gene expression correlated with a significant reduction in fish mortality when challenged with Streptococcus iniae, showcasing the potential of DFE as an effective immunostimulant1.
Recommended Dosage
Based on the study’s findings, the recommended dose of DFE for optimal immunostimulatory effects in rainbow trout is between 2.49 and 2.74 g/kg. This dosage range was determined using polynomial regression models, ensuring a scientifically backed recommendation for practical applications1.

Uses of Dandelion
Medicinal Uses
Immunostimulant: Dandelion flower extract has been shown to enhance immune responses in rainbow trout, increasing leukocyte and lymphocyte counts, and improving resistance to infections1 6.
Lactational Mastitis Treatment: Dandelion extract (Pugongying granules) is used in Chinese medicine to treat lactational mastitis, improving microbial diversity in breastmilk and reducing symptoms2.
Chemopreventive Agent: Dandelion has potential chemopreventive effects against colon cancer by inhibiting aberrant crypt foci formation and regulating apoptosis in both mice and human colorectal carcinoma cells3.
Hepatoprotective: Dandelion polyphenols protect against acetaminophen-induced liver toxicity by activating the Nrf-2/HO-1 pathway and inhibiting the JNK signaling pathway, reducing oxidative stress and inflammation7.
Animal Husbandry
Dairy Cows: Supplementing dairy cow diets with dandelion improves lactation performance, increases antioxidative activity, and enhances plasma metabolomics, leading to better milk yield and quality4.
Broiler Chickens: Dandelion supplementation in broiler chicken diets improves meat quality, increases the proportion of beneficial fatty acids, and enhances antioxidant capacity, reducing lipid oxidation5.
Laying Hens: Adding dandelion root to the diet of laying hens improves egg production, reduces lipid profiles, and decreases liver fat, helping to prevent lipid peroxidation and associated diseases8.

Adverse Effects of Dandelion
Hepatic Effects
Disruption of Liver Enzymes: Dandelion root extract has been shown to cause significant disruption of liver enzymes, specifically transaminases, indicating potential liver stress or damage1.
Hepatotoxicity: While dandelion polyphenols can protect against certain types of liver damage, such as that induced by acetaminophen, the extract itself can still cause liver enzyme disruptions under certain conditions3 4.
Renal Effects
Minimal Renal Impact: Studies indicate that dandelion root extract does not significantly affect renal parameters, suggesting minimal adverse effects on kidney function1.
Lipid and Hematological Parameters
No Significant Changes: Dandelion root extract does not significantly alter lipid and hematological parameters, indicating a relatively low risk of adverse effects in these areas1.
Toxicity Levels
Low Acute Toxicity: The acute toxicity study of dandelion root extract shows low intraperitoneal toxicity with an LD50 ranging between 500 and 5000 mg/kg, suggesting it is relatively safe at typical dosages1.

How has Dandelion Improved Patient Outcomes?
Improved Outcomes in Arteriovenous Fistula (AVF) Patients
Reduction in Complications: Dandelion hydropathic compress combined with conventional infrared irradiation significantly reduced complications associated with AVF, such as pain and poor blood flow, leading to a better quality of life for patients1.
Higher Clinical Efficacy: The combination treatment showed a higher clinical efficacy (96.30%) compared to conventional treatment alone (77.78%)1.
Enhanced Recovery Post-Jaw Surgery
Reduced Pain and Swelling: External application of dandelion combined with borneol effectively reduced facial swelling, pain, and limitation of mouth opening after jaw surgery, leading to higher patient satisfaction2.
Treatment of Acute Paraquat Poisoning
Improved Organ Function: The combination of compound monoammonium glycyrrhizinate and dandelion improved organ function, reduced the incidence of pulmonary fibrosis and multiple organ dysfunction syndrome (MODS), and lowered mortality rates in patients with acute paraquat poisoning3.
Management of Lactational Mastitis
Enhanced Microbial Diversity: Dandelion extract (Pugongying granules) increased microbial diversity in breastmilk, which is associated with reduced symptoms of lactational mastitis (LM) such as pain and fever. This treatment also increased the abundance of beneficial bacteria like Corynebacterium4.
Immunostimulation in Fish
Increased Immunity and Disease Resistance: Dietary supplementation with dandelion flower extract (DFE) in rainbow trout enhanced immune responses, increased survival rates against Streptococcus iniae infection, and improved overall health markers such as leukocyte counts and protein levels5.

Dandelion Mechanisms of Action
Anti-inflammatory and Antioxidant Effects
Dandelion extracts have been shown to reduce inflammation and oxidative stress, which are key factors in the development of atherosclerosis. In mice, dandelion supplementation decreased levels of inflammatory markers such as sVCAM-1 and MCP-1, and increased the expression of antioxidant enzymes like Cu/Zn SOD, Mn SOD, and catalase1. Additionally, dandelion polyphenols activate the Nrf-2/HO-1 pathway and inhibit the JNK signaling pathway, which helps protect against liver damage by reducing oxidative stress and inflammation2.
Lipid-Lowering Effects
Dandelion extracts also exhibit hypolipidemic effects by reducing plasma triglycerides, total cholesterol, and LDL cholesterol levels. This is achieved through the down-regulation of hepatic HMG-CoA reductase expression and increased fecal lipid excretion4. These effects contribute to the overall reduction of atherosclerosis risk.
Immunostimulatory Effects
Dandelion flower extract has been found to enhance immune responses in rainbow trout, increasing leukocyte and lymphocyte counts, and up-regulating the expression of immune-related genes such as interleukin-1β and interleukin-63. This immunostimulatory effect helps improve resistance against infections.
Uricosuric Effects
Dandelion root extract has demonstrated uricosuric effects by significantly reducing blood uric acid levels and increasing urinary uric acid excretion in hyperuricemic rats. This is achieved through the inhibition of xanthine oxidase activity, which is crucial for uric acid production5.
Growth and Metabolic Effects
In rainbow trout, dietary dandelion flower extract has been shown to improve growth performance, enhance antioxidant defense systems, and positively affect hemato-biochemical parameters. This includes increased weight gain, improved feed conversion ratio, and elevated levels of antioxidant enzymes like glutathione peroxidase and catalase6.
