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 pungent alkaloid-like compounds responsible for the fruit's heat and its counterirritant/analgesic action via TRPV1 receptor desensitisation.
Give ripe red fruit its colour and contribute antioxidant and anti-inflammatory activity.
Antioxidant and anti-inflammatory flavonoids identified in leaf and fruit extracts.

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).
Capsaicin causes intense burning sensation; avoid contact with eyes and mucous membranes. High oral doses can cause gastrointestinal irritation, nausea, and diarrhoea. Topical preparations may cause skin irritation and should be used diluted. Not recommended for individuals with active peptic ulcers. Caution with anticoagulants — capsaicin may enhance bleeding risk. During pregnancy, culinary amounts are considered safe, but high-dose supplements should be avoided. Repeated topical application leads to desensitisation (TRPV1 depletion), which is the basis for its analgesic use. Children under 2 should not be given capsaicin-containing topical products (Basu and Bhattacharyya, 2023).
Duke (2002) rates cayenne/chili pepper (Capsicum annuum) highly for its clinically documented analgesic, counterirritant, and rubefacient activities. Commission E approves topical capsaicin preparations for muscle pain, arthritis, and neuralgia (score 2). The active compound capsaicin depletes substance P in sensory neurons upon repeated application, reducing pain signals. Capsaicin cream (0.025–0.075%) is a validated treatment for post-herpetic neuralgia, diabetic neuropathy, and osteoarthritis pain. Internal use can irritate mucous membranes; external use requires avoiding contact with eyes and mucous membranes (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]
Bushy annual or short-lived perennial herb (grown as an annual in temperate climates) with glossy, oval to lance-shaped leaves. Small, star-shaped, white to greenish flowers give way to the characteristic fleshy, hollow fruit (a berry), which ripens from green through yellow to red and varies enormously in size, shape and pungency between cultivars.[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 Central and South America; cultivated worldwide in warm and temperate climates as a food and medicinal crop, thriving in full sun on well-drained soil.[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]
Fruit is picked at the desired stage of ripeness (green for milder use, fully red for maximum capsaicin and carotenoid content) through summer and autumn; seeds are separated and dried from fully ripe fruit.
Traditional Uses
Chili pepper fruit has a long history across the Americas and, after global spread, in many other traditional medicine systems as a warming digestive stimulant and topical counterirritant/analgesic for muscle and joint pain, building on capsaicin's now well-documented ability to desensitise pain-sensing nerve fibres with repeated application.[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.
Standardised capsaicin cream or patch applied to the affected area for muscle, joint or nerve pain; repeated application depletes substance P and reduces pain signalling.
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.
The EU herbal monograph on Capsici fructus gives semi-solid dosage forms corresponding to 40-53 mg capsaicinoids per 100 g, applied as a thin layer to the affected area 2-4 times daily, in adults and elderly. For medicated plasters, a maximum of 1 plaster per day applied for at least 4 and up to 12 hours, with at least 12 hours before a new plaster is applied to the same area. Not recommended under 18 years. Expect an initial burning sensation that lessens with repeated use. Note the monograph covers hot chilli fruit (C. annuum var. minimum and small-fruited C. frutescens), not sweet peppers. Educational reference only, not a prescription.
