Key Constituents
Principal antioxidant polyphenols, most concentrated in minimally oxidised green tea; epigallocatechin gallate (EGCG) is the best studied.
Caffeine gives tea its mild stimulant effect; L-theanine, a unique amino acid, is associated with calm alertness and modulates caffeine's effects.
Oxidative polymerisation products of catechins formed during black tea processing, contributing to black tea's colour and its own antioxidant profile.
The antimicrobial and anti-inflammatory principles of the root; the eudesmane core and the alpha,beta-methylene-lactone ring are essential for the antimicrobial activity.
A fructan polysaccharide abundant in the root (the genus Inula gives inulin its name).
Pharmacological Actions
Anti-inflammatory - sesquiterpene lactones (alantolactone, isoalantolactone) inhibit NF-kB and MAPK signalling and pro-inflammatory cytokines; total sesquiterpene lactones eased arthritis in animal models (potential in rheumatoid arthritis)
Antimicrobial, notably anti-staphylococcal (membrane-damaging) and anti-mycobacterial (active against Mycobacterium tuberculosis in vitro); supports respiratory and skin infection

Safety, Cautions & Contraindications
Generally safe in moderate consumption. High caffeine intake may cause insomnia, anxiety, palpitations, or dependence. Large amounts of green tea extract supplements may be hepatotoxic (rare). May reduce iron absorption if consumed with meals. Avoid very high supplement doses during pregnancy.
Duke (2002) rates tea (Camellia sinensis) as ++ and notes anti-aggregant, antioxidant, anticariogenic, and antibacterial activities at the experimental level (score 1). The catechins (EGCG, ECG) and polyphenols are responsible for the antioxidant and anticancer properties under research investigation. Duke notes that green tea preserves more polyphenols than black tea due to less oxidation. Regular tea consumption is associated with reduced cardiovascular risk. Excess consumption (>10 cups daily) may cause fluoride-related bone changes. Caffeine content is relevant for sleep disturbance, anxiety, and interactions with cardiovascular medications (Duke, 2002).
The sesquiterpene lactones (especially alantolactone) are known skin sensitisers and can cause allergic contact dermatitis; people sensitive to the daisy family (Asteraceae) should be cautious.
Large doses can cause nausea, vomiting and diarrhoea; safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.

Botanical Description
Evergreen shrub or small tree with glossy, dark green, leathery, finely toothed leaves. Small, fragrant, white flowers with a prominent central boss of yellow stamens are borne singly or in small clusters in the leaf axils. Commercial tea is made from the young leaves and unopened leaf buds ('sprouts'), processed differently to yield green, black, white or oolong tea from the same species.[15]
Tall, robust perennial herb with large, coarse, hairy leaves - broadly oval near the base and progressively smaller up the stem - arising from a thick, aromatic rhizome. Large, shaggy, bright yellow daisy-like flower heads with numerous narrow ray florets are borne at the top of stout, branching stems.[12]
Habitat
Native to the subtropical and tropical forests and hillsides of East and South Asia (China, India, Myanmar); cultivated extensively across Asia, Africa and elsewhere on well-drained, acidic upland soils.[15]
Grows in damp meadows, pastures, roadsides and woodland margins on moist, rich soils; native to Europe and Western Asia and naturalised in North America.[12]
Harvesting
The youngest leaves and unopened leaf buds ('flush') are hand- or machine-picked repeatedly through the growing season; how the fresh leaf is subsequently processed (withered, rolled, oxidised, fixed and dried) determines whether it becomes green, black, white or oolong tea.[15]
The root and rhizome are dug in autumn of the second or later year, when sesquiterpene lactone and inulin content is highest, then cleaned, sliced and dried.[12]
Traditional Uses
Elecampane root has a long European tradition, reflected in the old name 'elf dock', as a warming expectorant remedy for productive cough, bronchitis and chronic respiratory catarrh, and topically and internally as an antimicrobial for skin and wound infections.[12]
Preparations
Young leaf, minimally oxidised, infused in hot water; the least-processed and most-studied form for antioxidant polyphenol content.
Concentrated leaf extract standardised to catechin (e.g. EGCG) content, taken as capsules; used in some clinical studies, though high-dose extracts carry rare hepatotoxicity concerns.
Dried root simmered in water as a traditional expectorant and antimicrobial tea.
Dosage
The EU herbal monograph on green tea leaf (Camelliae sinensis non fermentatum folium) gives, for adults and elderly, 1.8-2.2 g of the whole or comminuted leaf in 100-150 mL of boiling water as an infusion, 3-5 times daily; a powdered herbal substance at 390 mg three times daily (up to 5 if necessary) is also listed. Contraindicated in gastric and duodenal ulcers, cardiovascular disorders such as hypertension and arrhythmia, and hyperthyroidism. Not recommended under 18 years. Educational reference only, not a prescription.
