The pungent alkaloid-like compounds responsible for the fruit's heat and its counterirritant/analgesic action via TRPV1 receptor desensitisation.

Carotenoids (capsanthin, beta-carotene)[8]

Give ripe red fruit its colour and contribute antioxidant and anti-inflammatory activity.

Safety, Cautions & Contraindications

Safety note[13, 14, 15, 16, 17, 18]Caution

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).

Safety note[13, 14, 15, 16, 17, 18, 19]Caution

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).

Safety note[11, 12, 13]Info

Food amounts are generally considered safe (berries in meals, drinks, sauces). (Williams et al., 2023).

Safety note[11, 12, 13, 14]Info

Duke (2002) includes cranberry primarily at the experimental level for its astringent, diuretic, and antioxidant properties. Commission E has not approved cranberry for specific indications, though there is evidence supporting its role in preventing urinary tract infections (UTIs) by inhibiting bacterial adhesion to uroepithelial cells (proanthocyanidins). Duke notes the high vitamin C and organic acid content. Food-grade consumption is considered safe and beneficial as a urinary acidifier (Duke, 2002).

Botanical Description

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]

Height: 0.5-1.5 m
Habit: Bushy annual or short-lived perennial herb
Leaves: Glossy, oval to lance-shaped
Flowers: Small, star-shaped, white to greenish, borne singly or in small clusters
Stem: Branching, semi-woody at the base in older plants
Root: Fibrous root system
Fruit: Fleshy, hollow berry, ripening green to yellow/orange/red, containing numerous flat seeds
Flowering Period: Summer, continuing until frost

Low, creeping, evergreen dwarf shrub (Ericaceae) with slender, wiry stems that root at the nodes. Leaves are tiny, alternate, leathery and ovate with in-rolled margins, dark green above and whitish beneath. Flowers are small, pink and four-petalled, sharply reflexed backward so that the protruding stamens and style resemble a crane's head and neck - the origin of the name 'craneberry', later shortened to 'cranberry'. The fruit is a small, round, tart red berry.[8]

Height: Prostrate, mat-forming (stems trailing, rarely more than 10-20 cm above the moss)
Habit: Low, creeping, evergreen dwarf shrub
Leaves: Tiny, alternate, leathery, ovate, in-rolled margins, whitish beneath
Flowers: Small, pink, four-petalled, sharply reflexed (crane's-head shape)
Stem: Slender, wiry, trailing, rooting at the nodes
Root: Shallow fibrous roots adapted to waterlogged, acidic peat
Fruit: Small, round, tart red berry
Flowering Period: June-August

Habitat

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]

Native to boggy, acidic wetlands - sphagnum bogs and marshes - across northern and central Europe and northern Asia, requiring waterlogged, nutrient-poor, acidic peat soils.[8]

Harvesting

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.

Parts: Fruit, Seed
Season: Summer to autumn, at desired ripeness

Berries are hand-picked or wet-harvested (traditionally by hand-raking the bog) in autumn once fully ripe and deep red.[8]

Parts: Fruit
Season: Autumn

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]

Cranberry has a long northern-European and Native American tradition as a food and folk remedy for urinary complaints, valued for its tart, astringent, vitamin-C-rich fruit. Modern research on its proanthocyanidins supports a role in reducing bacterial adhesion in the urinary tract, consistent with the traditional use for cystitis and recurrent urinary tract infections.[2, 11]

Preparations

Topical cream/ointment (capsaicin)[8]

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.

Juice[2]

Unsweetened juice, the traditional preparation used for urinary support.

Standardised extract capsule[2]

Proanthocyanidin-standardised extract, a concentrated form used in clinical trials for UTI prevention.

Dosage

Topical capsaicin cream[12]

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.
