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.
Diosgenin is an industrial precursor for making steroid hormones in the laboratory, but it is NOT converted into hormones in the human body. Oral bioavailability of diosgenin is low; in animal studies orally administered diosgenin restored skin thickness in ovariectomised mice and lowered blood lipids.
Pharmacological Actions
Antispasmodic / analgesic for menstrual cramps and muscle spasm (antinociceptive in animal models)
Anti-inflammatory for joint and inflammatory pain

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).
IMPORTANT myth-bust: wild yam / diosgenin is NOT converted into progesterone or DHEA in the body, so it does not work as a 'natural progesterone' - claims to that effect are incorrect. Consistent with this, a randomized placebo-controlled crossover trial of topical wild yam cream found no significant change in symptoms, serum/salivary progesterone, oestradiol, FSH or lipids.
Generally well tolerated orally (no acute or subchronic toxicity in animal studies); large doses may cause nausea or vomiting. Avoid medicinal doses in pregnancy and breastfeeding and in hormone-sensitive conditions as a precaution.

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]
Twining, herbaceous perennial vine with heart-shaped leaves arising from a knotty, woody, cinnamon-brown rhizome ('root'). Small, inconspicuous greenish-yellow flowers are borne on separate male and female plants, followed on female plants by small three-winged seed capsules.[10]
Habitat
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.
The knotty rhizome is dug in autumn once the aerial vine has died back, then cleaned and dried.
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]
Wild yam root has a Native American and Eclectic-medicine history as an antispasmodic remedy for colic, menstrual cramps and rheumatic joint pain (reflected in the old names 'colic root' and 'rheumatism root'); despite a persistent modern myth, its diosgenin content is not converted into progesterone or other hormones in the human body.[10]
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.
