Artemisia afra (African Wormwood)

Artemisia afra is a medicinal herb rather than a staple food, so macronutrient content is minimal and typically consumed in small doses (teas, tinctures, or direct leaf use). Key bioactive compounds include: Sesquiterpene lactones (artabsin, absinthin) at approximately 0.1-0.5% dry weight, responsible for bitter digestive properties. Monoterpene content includes α-thujone and camphor, with essential oil yield ranging from 0.2-1.2% of dry plant material. 1,8-cineole (eucalyptol) is a dominant essential oil constituent at 20-40% of total volatile fraction, contributing to bronchodilatory effects. Flavonoids including quercetin and luteolin are present at approximately 0.3-0.8% dry weight, providing antioxidant and anti-inflammatory activity. Phenolic acids (chlorogenic acid, caffeic acid) are present at trace to moderate levels (~0.1-0.3% dry weight). Tannins contribute astringent properties at roughly 1-3% dry weight. Micronutrient data is limited for this species specifically, but as with related Artemisia species, dried leaf material contains modest levels of iron (~15-25 mg/100g dry weight), calcium (~800-1200 mg/100g dry weight), and magnesium (~150-200 mg/100g dry weight). Vitamin C is present in fresh leaves but degrades significantly upon drying or boiling. Bioavailability note: Lipophilic compounds such as sesquiterpenes and essential oil constituents show enhanced absorption when consumed with fatty foods; aqueous infusions (teas) primarily extract water-soluble phenolics and flavonoids, limiting essential oil bioavailability to trace amounts.
