Chrysanthemum Greens (Chrysanthemum coronarium)

Chrysanthemum greens (Chrysanthemum coronarium) are a edible leafy vegetable rich in flavonoids, chlorogenic acid, and luteolin, which exert antioxidant and anti-inflammatory effects primarily by scavenging reactive oxygen species and modulating NF-κB signaling. Preliminary research suggests these bioactives may slow cellular senescence and support kidney function by reducing fibrotic and uremic markers.

Origin & History

Chrysanthemum greens (Chrysanthemum coronarium L.), also known as garland chrysanthemum or crown daisy, is a leafy vegetable native to East Asia, commonly cultivated in China, Japan, and Korea for culinary and medicinal use. The plant belongs to the Asteraceae family, with leaves and young shoots harvested as greens, and extracts typically prepared through solvent extraction using ethanol or water from leaves or whole plant material.

Historical & Cultural Context

Chrysanthemum coronarium has been used in Traditional Chinese Medicine (TCM) and Korean folk medicine for centuries as a functional food for detoxification, reducing inflammation, and supporting liver and kidney health. Modern research builds on this traditional context, investigating its potential for inflammatory bowel disease, metabolic disorders, and vascular protection.

Health Benefits

• May reduce cellular aging markers based on in vitro studies showing 10-50 μg/mL extract reduced senescence indicators in human endothelial cells (Preliminary evidence)
• Supports kidney health in animal models, with extract reducing blood urea nitrogen, serum creatinine, and kidney fibrosis markers in mice with induced chronic kidney disease (Preliminary evidence)
• Demonstrates anti-inflammatory effects in preclinical models, suppressing inflammatory pathways and cytokines in both cell and animal studies (Preliminary evidence)
• Shows potential for gut barrier protection in Drosophila models, mitigating intestinal inflammation and barrier damage (Preliminary evidence)
• Contains antioxidant compounds including chlorogenic acid and dicaffeoylquinic acids that exhibit stability and bioavailability (Preliminary evidence)

How It Works

Luteolin and chlorogenic acid in Chrysanthemum coronarium inhibit NF-κB pathway activation, reducing downstream pro-inflammatory cytokine expression including IL-6 and TNF-α. These flavonoids also directly scavenge reactive oxygen species and upregulate endogenous antioxidant enzymes such as superoxide dismutase (SOD) and catalase, which collectively suppress oxidative stress-driven cellular senescence. In kidney tissue, the extract appears to inhibit TGF-β1/Smad signaling, a key pathway driving interstitial fibrosis and the accumulation of collagen that impairs glomerular filtration.

Scientific Research

Current research on Chrysanthemum greens is limited to preclinical models with no human clinical trials, RCTs, or meta-analyses identified. Key studies include in vitro work on human umbilical vein endothelial cells showing anti-senescence effects, mouse models of chronic kidney disease demonstrating renoprotective properties, and Drosophila intestinal inflammation models (PMID: 41180090) showing gut barrier protection.

Clinical Summary

Human clinical evidence for Chrysanthemum coronarium extract remains limited; the most notable human-relevant data come from in vitro studies using 10–50 μg/mL extract concentrations on human umbilical vein endothelial cells (HUVECs), which demonstrated measurable reductions in senescence-associated β-galactosidase activity and p21 expression. Animal model studies have shown oral extract administration significantly lowered blood urea nitrogen (BUN) and serum creatinine levels while reducing kidney fibrosis markers, suggesting nephroprotective potential. No randomized controlled trials in humans have been published to date, meaning all benefit claims are preliminary and require significant clinical validation. The current evidence base is preclinical, and extrapolating dosages or therapeutic outcomes to humans is not yet scientifically supported.

Nutritional Profile

Chrysanthemum greens (Chrysanthemum coronarium) are a low-calorie leafy vegetable (~22 kcal per 100g raw). Macronutrients per 100g fresh weight: carbohydrates ~3.9g, protein ~2.4g, fat ~0.3g, dietary fiber ~2.4g. Moisture content is high at approximately 91-93%. Micronutrients are notably rich: Vitamin A (as beta-carotene ~2500-3500 μg RAE/100g, making it one of the richer leafy green sources), Vitamin C ~33mg/100g, Vitamin K ~350μg/100g (high bioavailability as phylloquinone), folate ~19-23μg/100g, Vitamin B2 (riboflavin) ~0.17mg/100g. Minerals include potassium ~569mg/100g, calcium ~105mg/100g (moderate bioavailability due to moderate oxalate content), iron ~1.7mg/100g (non-heme, enhanced by co-consumed Vitamin C), phosphorus ~44mg/100g, magnesium ~26mg/100g, and manganese ~0.43mg/100g. Bioactive compounds include chlorogenic acid and other caffeoylquinic acid derivatives (~50-200mg/100g dry weight), luteolin and apigenin glycosides (~10-80mg/100g dry weight), beta-carotene and lutein/zeaxanthin (~1.5-2mg/100g combined carotenoids supporting the documented anti-aging and anti-inflammatory properties), and volatile aromatic compounds including camphor, borneol, and chrysanthenone contributing to its distinctive flavor. Fiber composition includes both soluble and insoluble fractions supporting gut motility. Carotenoid bioavailability is enhanced when consumed with dietary fat. Calcium absorption is partially inhibited by moderate levels of oxalic acid (~70-100mg/100g).

Preparation & Dosage

Clinically studied dosages are limited to preclinical models: in vitro studies used 10-50 μg/mL extract, while animal studies used unspecified oral doses over 4 weeks. No human dosage recommendations or standardized extract concentrations have been established. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Safety & Interactions

Chrysanthemum greens are generally considered safe when consumed as a food vegetable across East Asian cuisines, with no established toxicity at culinary intake levels. Individuals with allergies to Asteraceae/Compositae family plants (including ragweed, marigold, and daisy) may experience cross-reactive allergic responses and should exercise caution. Concentrated extracts may theoretically potentiate the effects of anticoagulant medications such as warfarin due to flavonoid-mediated platelet inhibition, though no direct drug interaction studies exist. Pregnant and breastfeeding women should limit intake to normal food amounts and avoid high-dose supplemental extracts due to insufficient safety data.
