Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
Pharmacological Actions
Appetite stimulant for loss of appetite (approved use under German Commission E)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)

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).
As a member of the daisy family (Asteraceae/ragweed), it can cause allergic reactions in sensitive people; high doses reportedly cause stomach cramps, nausea and vomiting.
Avoid during pregnancy because of a traditional uterine-stimulating reputation.
Although traditionally used to support milk supply, there is no scientifically valid clinical evidence for the galactagogue use.

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]
Branching annual herb with a hairy, reddish, ridged stem and spiny, deeply lobed leaves with prominent pale veins. The flower heads are pale yellow, thistle-like, surrounded by a whorl of spiny, leaf-like bracts, giving the plant its 'spotted thistle' appearance.[4]
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 on dry, sunny waste ground, roadsides and rocky slopes; native to the Mediterranean region and Western Asia and naturalised elsewhere as a garden escape.[4]
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 flowering aerial parts are cut as the plant comes into flower, in summer, and dried in a warm, shaded, airy place to preserve the bitter principle cnicin.[4]
Traditional Uses
Blessed thistle has a long European folk reputation as a bitter digestive tonic for loss of appetite and dyspepsia (an approved use under German Commission E) and, more anecdotally, as a traditional galactagogue to support breast-milk supply, though robust clinical evidence for the latter is lacking.[4, 11]
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 flowering herb infused briefly in hot water as a bitter digestive tea, taken before meals.
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.
Traditional herbal references suggest around 1-2 g of dried herb per cup, taken before meals, up to three times daily. Educational reference only, not a prescription.
