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.
Theobromine is the dominant methylxanthine and the main stimulant/bronchodilator constituent, with lesser amounts of caffeine.
The principal bioactive polyphenols, responsible for most of cacao's antioxidant and cardiovascular activity.
A trace amine sometimes linked to cacao's reputed mood-elevating effects.
The fat fraction of the seed, classified as emollient and used in both food and topical products.

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).
• Stimulant effect (most common issue): cacao naturally contains theobromine (and some caffeine). In larger amounts it can feel like a “gentle coffee”: faster heartbeat, restlessness, trouble sleeping. • Heavy metals (quality matters): cocoa/chocolate can contain cadmium and lead from soil and processing. For frequent use (especially powders, dark chocolate, “ceremonial” paste), choose brands that publish lab tests. • Pregnancy (extra caution late pregnancy): some research suggests very polyphenol-rich foods (including cocoa/dark chocolate) could affect fetal circulation in late pregnancy. This is not “everyone must avoid chocolate,” but high-dose cacao drinks are something to discuss with a clinician if pregnant—especially in the 3rd trimester. • Breastfeeding: moderate chocolate/cacao is usually fine, but very large amounts can affect some infants (stimulation/irritability) because stimulant compounds can pass into milk in small amounts. • If you’re sensitive: cacao can worsen reflux/heartburn, trigger migraines in some people, or cause nausea—especially in strong ceremonial-style servings. • Medication caution: if you take stimulant-sensitive meds, have heart rhythm issues, severe anxiety, or use MAOI antidepressants, treat high-dose cacao drinks like a stimulant and be cautious
Duke (2002) notes that cacao is primarily known for its cardiotonic, CNS-stimulant, and broncholytic activities at the experimental level (score 1). Theobromine is identified as the principal active constituent responsible for mild bronchodilation and cardiovascular stimulation. Cocoa butter is classified as emollient (score 1). Chocolate's content of phenylethylamine may contribute to reported aphrodisiac properties. Duke notes that excessive consumption may be cariogenic and pro-acneic, and cocoa is a known allergen in sensitive individuals (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]
Small evergreen tree (Malvaceae), 4-8 m tall (up to 10 m unpruned), with a dense, spreading crown. Leaves are large, glossy and oblong. Small pink-white flowers are borne directly on the trunk and older branches (cauliflory), followed by large, ridged, football-shaped pods that ripen from green to yellow/orange/red-purple, each containing 20-60 seeds (the cocoa beans) embedded in sweet white pulp.[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]
Native to the tropical rainforest understorey of Central and South America (the Amazon and Orinoco basins), now cultivated throughout the tropics within about 20 degrees of the equator (notably West Africa, Southeast Asia and South America), requiring warm, humid, shaded conditions.[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]
Ripe pods are hand-harvested, cut open, and the seeds (with pulp) are removed, fermented for several days - essential for developing chocolate flavour and reducing bitterness - then dried and roasted.[1]
Traditional Uses
Cacao has an ancient Mesoamerican tradition (Maya and Aztec) as a ceremonial, medicinal and nutritive beverage, valued as a stimulant tonic and considered sacred - 'food of the gods', reflected in the genus name Theobroma. Modern research on its polyphenol (flavanol) content supports cardiovascular, antioxidant, anti-inflammatory and neuroprotective/cognitive benefits, particularly from minimally processed, high-flavanol cocoa.[1]
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.
Large clinical trials of cocoa flavanol supplementation for cardiovascular prevention have used around 500 mg/day of cocoa flavanols. Educational reference only, not a prescription; treat concentrated cacao as a mild stimulant (theobromine, some caffeine) and moderate intake accordingly, especially in pregnancy, with heart-rhythm conditions, or on stimulant-sensitive medication.
