# Citral ## Overview Citral is a mixture of two acyclic monoterpene aldehydes, geranial and neral. It is found naturally in the oils of many plants, including lemon, lemon verbena, and lemongrass. It is primarily used for its fragrance and flavoring properties. ## Primary Indications * Fragrance ingredient in perfumes, cosmetics, and household products. * Flavoring agent in food and beverages. * Limited therapeutic uses, often explored for potential anxiolytic or anti-inflammatory effects, though not established as standard practice. ## Adult Dosing Dosing is highly variable and depends on the specific product formulation and intended use. * **Fragrance/Flavoring:** Typically used in low concentrations (e.g., <0.1% in finished products). Specific concentrations are determined by manufacturers. ## Pediatric Dosing Dosing in children is not established for therapeutic use. Use in cosmetic or food products should follow manufacturer guidelines and consider age-appropriateness. ## Dose Adjustments No dose adjustments are typically needed as it is not a systemic medication with established pharmacokinetic parameters for dose modification. ## Contraindications * Known hypersensitivity to citral or its components. * May be a skin sensitizer; caution in individuals with eczema or sensitive skin. ## Adverse Effects * **Dermal:** Skin irritation, allergic contact dermatitis (especially with repeated or prolonged exposure). * **Sensory:** May cause mild eye irritation upon direct contact. * **Ingestion:** Generally recognized as safe (GRAS) in typical food additive amounts. Large ingestions are not well-studied. ## Key Drug Interactions No significant drug interactions are established when used as a fragrance or flavoring agent at typical concentrations. ## Monitoring * **Dermal:** Monitor for signs of skin irritation or allergic reaction. * **Ingestion:** Not typically monitored unless a very large quantity is ingested. ## Clinical Pearls * Citral is a common component of "natural" lemon scents. * Its potential for skin sensitization should be considered, particularly in leave-on cosmetic products or for individuals with pre-existing skin conditions. * Therapeutic efficacy and safety for medicinal purposes are not well-established. *** **Disclaimer:** This information is intended for clinical use and does not replace professional judgment.
