# Citral ## Overview Citral is a mixture of two acyclic monoterpene geometric isomers, geranial and neral. It is found in the essential oils of various plants, including lemon myrtle, lemongrass, lemon verbena, and citrus peels. It is often used as a fragrance and flavoring agent. ## Primary Indications Citral is primarily used as a flavoring agent in food and beverages and as a fragrance in cosmetics and perfumes. There is limited evidence supporting its use as a therapeutic agent, although some preclinical studies suggest potential antioxidant, anti-inflammatory, and antimicrobial properties. ## Adult Dosing Citral is generally recognized as safe (GRAS) by the FDA for use as a flavoring agent in food. Specific dosing depends on the intended application and regulatory guidelines for food additives and cosmetic ingredients. Therapeutic dosing is not established. ## Pediatric Dosing No established pediatric dosing for therapeutic use. Safety of ingested amounts in food or topical exposure in cosmetics is generally considered acceptable within typical product formulations. ## Dose Adjustments Not applicable as there is no established therapeutic dosing. ## Contraindications Hypersensitivity to citral or any component of the formulation. ## Adverse Effects When used in typical concentrations in food or cosmetics, citral is generally well-tolerated. Potential adverse effects, particularly with concentrated topical exposure, may include: * Skin irritation * Allergic contact dermatitis ## Key Drug Interactions No significant drug interactions have been established for citral when used as a flavoring or fragrance agent. ## Monitoring Monitoring is not typically required for use as a flavoring or fragrance agent. For individuals with known sensitivities, monitoring for skin reactions may be warranted. ## Clinical Pearls * Citral is a common component of essential oils and is responsible for their characteristic lemony scent. * While it has shown some interesting preclinical biological activity, robust clinical evidence for therapeutic efficacy is lacking. * For individuals with known sensitivities or allergies to citrus or certain fragrances, caution is advised with products containing citral. *** *Disclaimer: This information is intended for clinical use and is based on available data.
