Artemisia annua contains artemisinin, a potent antimalarial compound that disrupts parasite metabolism through oxidative stress. The herb demonstrates significant anti-inflammatory, antimicrobial, and hepatoprotective properties through multiple molecular pathways.
Reported Benefits (Provisional)
Origin & History
Qing Hao, also known as sweet wormwood, is a plant native to Asia. The leaves are harvested and dried for medicinal purposes.
Research Narrative (Provisional)
Numerous studies, including randomized controlled trials, support the use of Qing Hao for treating malaria due to its active compound, artemisinin.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Qing Hao (Artemisia annua) is a medicinal herb rather than a dietary staple, so its nutritional profile is characterized primarily by bioactive compounds rather than macronutrients. Macronutrient content per 100g dried herb: protein approximately 10-15g, carbohydrates approximately 40-50g (including structural polysaccharides), dietary fiber approximately 20-25g, fats approximately 2-5g including small amounts of essential fatty acids. Key bioactive sesquiterpene lactones: artemisinin (0.01-0.8% dry weight, averaging ~0.3-0.5% in high-yield cultivars), artesunate, artemether, dihydroartemisinin, and arteannuin B. Flavonoids present at 1-2% dry weight including quercetin (~0.1-0.5mg/g), luteolin, apigenin, kaempferol, and casticin. Essential oils constitute 0.1-0.5% dry weight, dominated by camphor (~20-25% of oil fraction), germacrene D (~10-15%), beta-caryophyllene (~5-10%), and alpha-pinene (~3-5%). Coumarins including scopoletin and scopolin are present at trace levels (~0.01-0.05%). Polyphenolic acids include chlorogenic acid and caffeic acid derivatives at approximately 0.5-1mg/g. Micronutrients include iron (~15-20mg/100g), calcium (~300-400mg/100g), potassium (~500-600mg/100g), magnesium (~150-200mg/100g), zinc (~2-3mg/100g), and manganese (~3-5mg/100g). Vitamins detected include vitamin C (~10-20mg/100g in fresh herb, largely degraded upon drying), small amounts of vitamin E (tocopherols ~1-2mg/100g), and B-complex vitamins including riboflavin and niacin at trace levels. Bioavailability notes: artemisinin has poor oral bioavailability (~30%) due to rapid first-pass metabolism and short half-life of approximately 1-3 hours; fat co-administration modestly improves absorption. Flavonoid bioavailability is enhanced by hot-water extraction. Artemisinin is largely insoluble in water and is better extracted using ethanol or oil-based preparations.
Reported Mechanism (Provisional)
Artemisinin and its derivatives generate reactive oxygen species when exposed to iron, creating oxidative stress that damages parasite membranes and proteins. The herb's flavonoids and sesquiterpene lactones inhibit NF-κB signaling pathways, reducing pro-inflammatory cytokine production. Additionally, artemisinin activates AMPK pathways and modulates cytochrome P450 enzymes to enhance liver detoxification processes.
Clinical Narrative (Provisional)
Multiple randomized controlled trials involving over 1,000 patients demonstrate artemisinin-based combination therapy achieves 95-99% cure rates for uncomplicated malaria. Small-scale studies (n=50-100) show 40-60% reduction in inflammatory markers like IL-6 and TNF-α after 4-8 weeks of supplementation. Limited human trials suggest hepatoprotective effects, though most liver function data comes from animal studies. Evidence for immune enhancement remains preliminary with only observational studies available.
