Dandelion Extract

Also known as: Taraxacum officinale, dandelion root extract, dandelion leaf extract, dandelion polysaccharides, Taraxacum mongolicum

Overview

Dandelion (Taraxacum officinale) is a medicinal herb with a range of bioactive compounds, including polysaccharides, flavonoids (e.g., luteolin, hesperetin derivatives), sesquiterpenoids, and phenolic compounds, which contribute to its antioxidant, anti-inflammatory, hepatoprotective, and immunomodulatory properties [7][4]. Research indicates that dandelion extract, particularly from leaves and flowers, can improve metabolic health by reducing serum triglycerides, total cholesterol, and LDL-cholesterol while increasing HDL-cholesterol in animal models of atherosclerosis and nonalcoholic fatty liver disease [1][3]. It also demonstrates potent anti-inflammatory effects by suppressing iNOS and COX-2 expression, thereby reducing nitric oxide and prostaglandin E2 production in macrophages [2]. Additionally, dandelion leaf extract enhances immunological responses, increasing cytokine production (IFNγ, TNFα, IL4, IL10) and regulatory T-cell markers (CD4+, CD25+) in infected mice, suggesting immune-stimulating potential [5]. These effects are mediated through modulation of oxidative stress pathways, lipid metabolism, and inflammatory signaling, supporting its traditional use in liver and metabolic disorders.

Dosage Guide

Therapeutic Doses

For treatment of specific conditions

Hepatic support (fatty liver)500-1000 mg/day of leaf extractBased on animal studies using 2–5 g/kg; human equivalent dose estimated at 80–400 mg/kg, typical supplements provide 500–1000 mg
Antioxidant/anti-inflammatory support300-600 mg/day of root or leaf extractStandardized to 4-5% flavonoids or 2-3% sesquiterpene lactones
Metabolic health (lipid/glucose)1000 mg twice dailyBased on extrapolation from rodent studies showing lipid and glucose improvements

Special Forms

Alternative forms for specific needs

Dandelion leaf extract (aqueous)

For immunomodulation and diuretic effects

Dandelion root extract (ethanol-based)

For liver detoxification and bile stimulation

Standardized polysaccharide extract

For immune and antioxidant support

Clinical Notes

  • Generally recognized as safe (GRAS), but may cause allergic reactions in individuals sensitive to Asteraceae plants.
  • Potential diuretic effect; monitor electrolytes if used with prescription diuretics or lithium.
  • May enhance hypoglycemic effects; monitor blood glucose when used with diabetes medications.
  • Limited human trials; most evidence is preclinical (animal and in vitro studies).
  • Avoid in cases of bile duct obstruction due to choleretic effects.
