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
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.
Parthenolide is the principal active compound, to which extracts are often standardised; it is biosynthesised and stored in the glandular trichomes of the aerial parts.

Safety, Cautions & Contraindications
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).
As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. Chewing fresh leaves commonly causes mouth ulcers and oral soreness.
Stopping feverfew abruptly after prolonged use can cause a 'post-feverfew' rebound of headache, anxiety and muscle/joint stiffness. Avoid in pregnancy (uterine-stimulant) and breastfeeding, and use caution with anticoagulant/antiplatelet medicines.

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]
Aromatic perennial herb (Asteraceae), 20-60 cm tall, with much-branched, downy stems. Leaves are yellow-green, bipinnately divided and strongly scented. Small, daisy-like flower heads have white ray florets and a flat yellow disc, borne in loose clusters.[13]
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 the Balkans and Caucasus region, now naturalised across Europe, North America and elsewhere; grows on disturbed ground, walls, roadsides and waste places, and is widely cultivated.[11]
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.
Leaves (aerial parts) are gathered during the growing season, ideally at flowering, and dried or used fresh.[13]
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]
Feverfew has a long European folk tradition, its name derived from 'febrifuge' (fever-reducer), as a remedy for fevers, headaches and joint pain. Modern use and clinical research focus on migraine prevention, with parthenolide identified as the key active compound responsible for inhibiting the inflammatory pathways implicated in migraine.[11]
Preparations
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.
Freeze-dried or standardised-parthenolide extract, the form used in most clinical trials.
Dosage
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.
Clinical trials for migraine prevention have most often used standardised extracts providing around 0.2-0.6% parthenolide, taken daily; do not stop abruptly after prolonged use given a documented 'post-feverfew' rebound syndrome. Educational reference only, not a prescription; avoid in pregnancy and with anticoagulants.

Pairings
Not documented
Feverfew and ginger 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.[14, 15, 16]
