Ju Hua (Chrysanthemum morifolium)
Chrysanthemum morifolium contains bioactive flavonoids including luteolin and apigenin that reduce inflammation through NF-κB pathway inhibition. This herb primarily supports eye health by reducing oxidative stress and inflammation in ocular tissues.
Origin & History
Ju Hua comes from the flowers of Chrysanthemum morifolium, cultivated in China and other parts of Asia. The flowers are dried for medicinal use.
Historical & Cultural Context
Ju Hua has been used in Chinese culture for centuries, not only as a medicine but also as a popular tea ingredient.
Health Benefits
- Supports eye health by reducing oxidative stress, which helps maintain vision and prevent age-related eye diseases. - Reduces inflammation by inhibiting pro-inflammatory cytokines, which can alleviate symptoms of chronic inflammatory conditions. - Enhances skin health by promoting collagen production, leading to improved skin elasticity and reduced signs of aging. - Boosts immune function by increasing the activity of natural killer cells, which are essential for combating infections. - Lowers blood pressure by relaxing blood vessels, which can reduce the risk of hypertension and associated cardiovascular issues. - Improves sleep quality by regulating neurotransmitter levels, leading to more restful and restorative sleep. - Provides antioxidant protection by scavenging free radicals, which helps protect cells from damage and supports overall health.
How It Works
Chrysanthemum's flavonoids luteolin and apigenin inhibit the NF-κB inflammatory pathway and reduce pro-inflammatory cytokines like TNF-α and IL-6. These compounds also activate antioxidant enzymes including superoxide dismutase and glutathione peroxidase, protecting cells from oxidative damage. The herb's chlorogenic acid enhances collagen synthesis by promoting fibroblast activity.
Scientific Research
Research indicates that Ju Hua may have antioxidant and anti-inflammatory properties. Some studies suggest benefits for eye health.
Clinical Summary
A randomized controlled trial with 120 participants showed chrysanthemum tea reduced eye fatigue symptoms by 40% after 4 weeks of daily consumption. Preliminary studies suggest 200-400mg daily of standardized extract may reduce inflammatory markers, though most research remains in animal models. Human studies are limited in number and sample size, requiring more robust clinical trials to confirm therapeutic effects. Current evidence is promising but preliminary.
Nutritional Profile
Ju Hua (Chrysanthemum morifolium) is a low-calorie botanical ingredient with a complex phytochemical profile. Macronutrients per 100g dried flower: carbohydrates approximately 60-65g (primarily polysaccharides and soluble fiber), protein approximately 6-8g (containing essential amino acids including glutamic acid, aspartic acid, and glycine), fat approximately 1-2g (including small amounts of linolenic and linoleic fatty acids), and dietary fiber approximately 15-20g. Key micronutrients include potassium (approximately 400-500mg/100g dried), calcium (approximately 150-200mg/100g), magnesium (approximately 50-70mg/100g), iron (approximately 5-8mg/100g), zinc (approximately 1-2mg/100g), and selenium (trace amounts, approximately 2-5mcg/100g). Vitamin content includes vitamin C (approximately 30-50mg/100g dried, though heat-sensitive and reduced in teas), riboflavin (B2, approximately 0.3mg/100g), niacin (B3, approximately 1.5mg/100g), and beta-carotene as a provitamin A precursor (approximately 1-3mg/100g). Primary bioactive compounds include flavonoids: luteolin (0.1-0.5% dry weight), apigenin (0.05-0.3% dry weight), acacetin, and quercetin glycosides. Chlorogenic acid and 3,5-dicaffeoylquinic acid are present at approximately 0.5-2% dry weight. Essential oils constitute approximately 0.2-0.9% including borneol, camphor, and chrysanthenone. Polysaccharides range from 5-10% dry weight and contribute significantly to immunomodulatory effects. Adenosine is present in trace amounts (~0.01%). Bioavailability notes: flavonoid absorption is enhanced when consumed as a warm infusion; polyphenol bioavailability is moderate (15-30%) and can be improved with concurrent consumption of vitamin C-rich foods; polysaccharide bioavailability is partially dependent on gut microbiome activity; fat-soluble carotenoids require dietary fat for optimal absorption.
Preparation & Dosage
Dosage typically ranges from 5 to 10 grams in decoction. Consult a healthcare provider before use.

Safety & Interactions
Chrysanthemum is generally well-tolerated, though allergic reactions may occur in individuals sensitive to Asteraceae family plants. The herb may enhance effects of anticoagulant medications due to its blood-thinning properties. Pregnant and breastfeeding women should avoid use due to insufficient safety data. High doses may cause digestive upset, dizziness, or skin sensitivity in some individuals.
