Traditional Uses
In Uyghur and Kazakh traditional medicine of Xinjiang and Central Asia, the aerial parts of rock wormwood are prepared as a tea or decoction to reduce fever, relieve inflammation and stomach upset, ease indigestion and nausea, and treat allergic complaints such as urticaria as well as jaundice, influenza, and various forms of hepatitis (Su et al., 2018).
Botanical Description
Artemisia rupestris (rock wormwood) is an aromatic perennial herb of the aster family, growing 10–40 cm tall from a woody rootstock and often forming small tufts. The slender, erect to ascending stems bear finely divided, pinnately or bipinnately dissected leaves with narrow, linear segments, the foliage typically grey-green and sparsely hairy and emitting a strong sage-like scent. Numerous small, nodding, globose to hemispheric flower heads, 2–4 mm across, are arranged in a narrow leafy panicle or raceme; the disc florets are yellow and there are no conspicuous rays. It is distributed across the mountains and steppes of Central Asia, Siberia, and northwestern China, notably the Altai, Tianshan, and Kunlun ranges of Xinjiang, where it grows on grassland, gravelly slopes, and forest margins at elevations of roughly 1,500–4,000 m.
Active Constituents
Rupestonic acid
Guaiane-type sesquiterpeneConcentration: Characteristic marker sesquiterpene of the species
The signature sesquiterpene of A. rupestris and the lead compound behind its anti-influenza reputation. Rupestonic acid and its semisynthetic ester derivatives show significant inhibition of influenza A and B viruses in vitro, some derivatives markedly more potent than oseltamivir in cell assays.
Flavonoids (luteolin, chrysosplenetin B, capillarisin derivatives)
Flavonoids / methoxylated flavonesConcentration: Major polyphenolic fraction of the aerial parts
Includes luteolin, chrysosplenetin B and 6-demethoxy-4'-O-methylcapillarisin. Several show neuraminidase-inhibitory and antiviral activity; the capillarisin derivative has been reported to suppress influenza replication via activation of the Nrf2/heme-oxygenase-1 pathway.
Quercetin and glycosides (rutin, hyperoside, isorhamnetin glycosides)
Flavonol glycosidesConcentration: Present in the aerial parts
Antioxidant flavonols contributing to the plant's anti-inflammatory and radical-scavenging activity used traditionally for fever and 'heat' conditions.
α-Terpinyl acetate
Oxygenated monoterpene esterConcentration: Principal essential-oil component (reported ~37%)
The dominant volatile of the essential oil, contributing to aroma and to reported insecticidal/repellent activity of the oil against stored-product pests.
Spathulenol and α-terpineol
Sesquiterpene alcohol / monoterpene alcoholConcentration: Notable essential-oil components (~10% each)
Oxygenated terpenoids of the volatile oil with mild antimicrobial and anti-inflammatory properties.
Thiophene derivatives
Polyacetylene-derived thiophenesConcentration: Minor constituents
Sulphur-containing thiophenes isolated from the whole plant, some contributing to the neuraminidase-inhibitory (antiviral) activity of the extract.
Preparation Methods
Decoction / infusion (traditional Uyghur medicine)
Parts: Aerial parts, Whole herb
In traditional Uyghur (Uygur) medicine of Xinjiang the dried aerial parts are decocted or infused for colds, fever and 'detoxification', and used as an anti-inflammatory and analgesic remedy. As with other Artemisia species, wormwood herbs are avoided in pregnancy.
Essential oil (research / repellent use)
Parts: Aerial parts
The steam-distilled essential oil has been investigated as an insect repellent and grain-protectant; it is for external/experimental use only.
