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.
Thujone is the neurotoxic, safety-limiting constituent responsible for tansy's real internal-use toxicity.
Contribute to the plant's bitter taste and antimicrobial activity.

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).
CAUTION: Tansy is considered toxic in medicinal doses and is NOT recommended for internal use. Thujone can cause convulsions, liver and kidney damage. Contraindicated in pregnancy (uterotonic and abortifacient). External use (as insect repellent) is generally safe. For information and historical reference only — do not use internally.
Duke (2002) rates tansy as ++ but emphasizes important safety concerns. The plant contains thujone (a neurotoxic ketone) and camphor, making it potentially toxic with internal use. Documented activities include emmenagogue, abortifacient (score 1), and insecticide. Duke strongly cautions against internal use except under professional supervision, noting that historical cases of tansy poisoning have resulted in convulsions and death. Topical use as an insect repellent is safer but should still avoid prolonged skin contact due to the essential oil's sensitizing potential. Strictly contraindicated in pregnancy (Duke, 2002).
External Ids
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), 50-120 cm tall, with erect, reddish, ridged stems. Leaves are finely divided, fern-like and strongly camphor-scented. Flat-topped clusters of small, yellow, button-like flower heads lack ray florets (petals).[11]
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 Europe and temperate Asia, widely naturalised elsewhere; grows on roadsides, waste ground, riverbanks and disturbed grassland.[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.
Flowering aerial parts are cut in summer, when in full flower, and dried for external/historical use; given this plant's real toxicity (thujone content) at internal doses, this record does not recommend or describe internal harvesting for medicinal consumption.[11]
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]
Tansy has a long European history as a strewing herb, insect repellent and, historically, an internal vermifuge and emmenagogue, but its thujone and camphor content make internal medicinal use unsafe by modern standards. Today it is used, with caution, mainly as an external insect repellent; the traditional internal uses are recorded here for historical reference only, not as a recommendation.[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.
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.
Tansy is NOT recommended for internal use at any dose given its thujone content and documented toxicity (convulsions, liver/kidney damage) - internal use recorded here is for historical reference only. External use (e.g. as an insect repellent) should avoid prolonged skin contact. Educational reference only, not a prescription; strictly avoid in pregnancy.
