# Citral ## Overview Citral is a mixture of two acyclic monoterpene geometric isomers, geranial (trans-citral) and neral (cis-citral). It is a naturally occurring compound found in the oils of several plants, such as lemon, lemon balm, and lemongrass. It is often used as a flavoring agent and in fragrances. ## Primary Indications Citral is primarily used as a flavoring agent in food and beverages and as a component in perfumes and cosmetics. It has some limited use in traditional medicine for various ailments, but robust clinical evidence for efficacy in these applications is often lacking. ## Adult Dosing There is no standard pharmaceutical dosing for citral as it is primarily used in food and fragrance applications. When used as a flavoring agent, concentrations are typically very low, dictated by good manufacturing practices and regulatory limits for food additives (e.g., generally recognized as safe - GRAS - by the FDA). ## Pediatric Dosing No specific pediatric dosing recommendations exist for citral. Its use in food and fragrance products would follow general population guidelines. ## Dose Adjustments Dose adjustments are not applicable as citral is not typically prescribed as a medication with defined therapeutic doses. ## Contraindications - Hypersensitivity to citral or any component of products containing citral. ## Adverse Effects - **Dermal:** Skin irritation, allergic contact dermatitis, photosensitivity reactions. - **Gastrointestinal:** Nausea, vomiting, diarrhea (reported with very high oral intake, not typical for food use). - **Respiratory:** Bronchospasm in sensitive individuals (rare). ## Key Drug Interactions No significant drug interactions have been established with citral when used at typical dietary or cosmetic concentrations. ## Monitoring Monitoring is generally not required when citral is consumed in food or used in cosmetic products at approved levels. For individuals experiencing adverse reactions, discontinue use and consult a healthcare professional. ## Clinical Pearls - Citral's primary role is in sensory applications (flavor and fragrance). - Allergic contact dermatitis is the most common adverse effect associated with topical exposure. - Individuals with known sensitivities should avoid products containing citral. *** **Disclaimer:** This information is intended for educational purposes and does not substitute for professional medical advice.
