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.
Principal immunomodulatory constituents, the main focus of anticancer-adjunct and immune research.
Bitter triterpenes associated with anti-inflammatory, hepatoprotective and adaptogenic activity.

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).
Generally well tolerated at standard doses. May cause mild digestive upset, dry mouth, or dizziness in some individuals. May enhance the effects of anticoagulant and antihypertensive medications. Avoid during pregnancy and breastfeeding. Extended use beyond 6 months is not well studied in humans.
Duke (2002) rates reishi (Ganoderma lucidum) as + and notes immunostimulant, hepatoprotective, antioxidant, antitumor, and hypoglycemic activities at the experimental level (score 1). It is a key adaptogen in traditional Chinese medicine, valued for its polysaccharide (beta-glucan) content. Duke notes antiviral (score 1) and anti-aggregant activities. No strong clinical trials existed at time of publication, but lentinan and polysaccharide fractions from related species show immunomodulatory potential. Duke suggests caution in bleeding disorders due to anti-aggregant activity (Duke, 2002).

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]
Bracket (shelf) fungus (not a true plant) that grows on the trunks and stumps of deciduous trees. It develops a hard, kidney- or fan-shaped cap with a glossy, varnished, red-brown to mahogany crust and concentric growth rings, often on a lateral woody stalk; the pale underside is covered in fine pores that release rusty-brown spores. The mycelium spreads through the wood substrate before fruiting.[1]
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 as a wood-decay fungus on the stumps and trunks of deciduous trees (notably maple and other hardwoods) in East Asian forests; also widely cultivated commercially on hardwood logs or sawdust substrate.
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]
Wild fruiting bodies are collected once mature; cultivated material is harvested from logs or substrate at maturity, then dried and processed into slices, powder or extract.
Traditional Uses
Reishi/lingzhi, the 'mushroom of immortality', is one of the most revered tonic fungi in traditional Chinese medicine, used for centuries to support vitality, calm the spirit, strengthen immunity and promote longevity; this traditional tonic reputation is now studied for immunomodulatory, anticancer-adjunct and metabolic effects.[1, 4]
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.
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.
