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 principal bioactive triterpene saponins of the root, considered responsible for most of ginseng's adaptogenic, neuroprotective and immunomodulatory activity; the ratio of protopanaxadiol- to protopanaxatriol-type ginsenosides differs between fresh, white and red ginseng.
Contribute to the immunomodulatory activity of the root.
Minor constituents contributing to the aroma and antioxidant 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 in short-term use (up to 3 months). May cause insomnia, headache, or gastrointestinal upset at high doses. Avoid during pregnancy and breastfeeding. May interact with warfarin, MAOIs, and diabetic medications. Not recommended for continuous use without breaks.
Duke (2002) rates Korean/Oriental ginseng (Panax ginseng) as highly active with clinical support for adaptogenic, immunostimulant, and performance-enhancing effects. Commission E approves standardized ginseng root extract (4–7% ginsenosides) as a tonic for fatigue and during convalescence. Dose: 200–600 mg standardized extract daily. Duke cautions about 'Ginseng Abuse Syndrome' (GAS) with overdose — symptoms include hypertension, insomnia, edema, and nervousness. Drug interactions are notable: ginseng potentiates MAOIs and may interact with warfarin, digoxin, and stimulants. Cycle use (2–3 weeks on, 2 weeks off) is recommended (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]
Slow-growing perennial herb (Araliaceae), 30-60 cm tall, harvested at 4 years of age or older. A single erect stem bears a whorl of palmately compound leaves, each with 3-5 toothed leaflets, at its top. Small greenish-white flowers are borne in a single terminal umbel, followed by small red berries. The fleshy, often forked or human-shaped taproot - the origin of the name 'ginseng' ('renshen', man-root) - is the medicinal part.[3]
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]
Native to the cool-temperate deciduous mountain forests of Manchuria, Korea and the Russian Far East. Historically wild-harvested, it is now predominantly cultivated, mainly in Korea and China, under artificial shade for several years before harvest.[1]
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 is harvested after at least 4-6 years of growth, once its ginsenoside content is fully developed. Roots are either air-dried as 'white ginseng' or steamed and then dried as 'red ginseng', a processing step that alters the ginsenoside profile.[3]
Traditional Uses
Ginseng is one of the most celebrated tonic herbs of East Asian traditional medicine, used for millennia as a general adaptogen to restore vitality, support recovery from illness and improve stamina and cognitive performance. Modern clinical research supports adaptogenic, immunomodulatory, antioxidant, neuroprotective and mild antidiabetic effects consistent with this traditional use.[1, 7]
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.
Commission E-recognised standardised extract (4-7% ginsenosides), the most clinically studied preparation.
Traditional processed form (steamed then dried), which alters and concentrates the ginsenoside profile compared with white (unprocessed) ginseng.
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.

Not documented
Ginseng and feverfew both reduce blood clotting/platelet stickiness, so taking them together may add up and raise the risk of bruising or bleeding — use caution, especially before surgery or alongside blood-thinning drugs.[19, 20]
