About

What it is and where it shows up.

Red chilli is the dried fruit of Capsicum species (primarily Capsicum annuum and Capsicum frutescens), widely used as a spice and flavouring for its characteristic pungency, colour, and aroma. Its primary bioactive compound, capsaicin, activates the TRPV1 receptor on sensory neurons, producing the characteristic heat sensation, and is also exploited medicinally as a topical analgesic.

Safety summary

The regulatory and scientific consensus.

Red chilli is generally recognised as safe at normal culinary consumption levels; however, high or excessive intake has been epidemiologically associated with increased risk of gastric, esophageal, and gallbladder cancers in some populations. Capsaicin causes gastric mucosal irritation and is contraindicated for individuals with peptic ulcers, GERD, or IBS. No formal ADI has been established by JECFA or EFSA; the German Federal Institute for Risk Assessment (BfR) has proposed 5 mg capsaicin per kg body weight as a precautionary not-to-exceed level per meal.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
FSANZ (Food Standards Australia New Zealand) (Australia)	Approved	Red chilli is permitted as a natural spice and flavouring ingredient under FSANZ Food Standards Code; no specific maximum limit for capsaicin content is prescribedsource
EFSA (European Food Safety Authority) (European Union)	Approved	Red chilli is approved as a natural spice and flavouring under EU food law; EFSA's 90th Advisory Forum (Nov–Dec 2023) reviewed health risks of capsaicinoids with a focus on gastric mucosal effects; paprika extract used as a colour additive carries E160c under separate authorisationsource
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Red chilli (whole, powder, and crushed) is regulated as a spice under FSSAI Food Safety and Standards (Spices and Condiments) Regulations; standards define permissible limits for moisture, total ash, acid-insoluble ash, volatile oil, and pesticide residues, as well as maximum limits for aflatoxins and Sudan dyes as adulterantssource
FDA (Food and Drug Administration) (United States)	Approved	Capsicum and paprika are Generally Recognised as Safe (GRAS) for use in food under 21 CFR Parts 182 and 184; capsaicin is also approved as an external analgesic counterirritant but is not considered GRAS for internal medicinal use (fever blisters/cold sores)

Who should approach with care

Whose guidance would steer them away.

Ibs — Capsaicin stimulates gastrointestinal TRPV1 receptors on C-fibre afferent neurons, producing physiological and pharmacological effects on the GI tract that can exacerbate abdominal pain, urgency, and diarrhoea in IBS patients.

Ibd — Capsaicin-induced mucosal irritation and modulation of intestinal motility and secretion can trigger or worsen flares in individuals with Crohn's disease or ulcerative colitis.

Children — Children have lower tolerance thresholds for capsaicin-mediated mucosal irritation and are at greater risk of GI discomfort, vomiting, and respiratory distress from high-capsaicin foods.

Pregnancy — Excessive red chilli intake during pregnancy may exacerbate heartburn and gastroesophageal reflux, which are already common in pregnancy; moderate culinary use is generally considered acceptable.

Migraine — Spicy foods containing capsaicin are a well-recognised dietary migraine trigger in susceptible individuals, likely via TRPV1-mediated neurogenic inflammation and sensory nerve sensitisation.
