# Citral ## Overview Citral is a mixture of two acyclic monoterpene aldehydes, geranial (trans-isomer) and neral (cis-isomer). It is found naturally in the oils of various plants, such as lemon, lemongrass, and lemon myrtle. It is primarily used for its flavoring and fragrance properties. ## Primary Indications * Flavoring agent in food and beverages. * Fragrance component in cosmetics and perfumes. * Limited use in traditional medicine, but lacks robust clinical evidence for specific therapeutic indications. ## Adult Dosing There are no standardized therapeutic doses for citral. Its use is typically at concentrations determined by flavoring or fragrance requirements, generally considered safe at levels used in consumer products. ## Pediatric Dosing No specific pediatric dosing is established for citral as a therapeutic agent. ## Dose Adjustments Not applicable as there are no established therapeutic doses. ## Contraindications * Known hypersensitivity to citral or its components. * Skin sensitization may occur, particularly with prolonged or repeated topical exposure. ## Adverse Effects * **Dermal:** Skin irritation, allergic contact dermatitis. * **Oral:** Generally considered safe in food and beverage concentrations. High oral doses may cause gastrointestinal upset. * **Inhalation:** May cause respiratory irritation. ## Key Drug Interactions No significant drug interactions are documented for citral in a pharmaceutical context. However, it may potentiate the photosensitizing effects of certain medications if used topically in conjunction with phototherapy. ## Monitoring * For topical applications, monitor for signs of skin irritation or allergic reactions. * For oral use in food/beverage, consider regulatory limits and individual sensitivities. ## Clinical Pearls * Citral is a common flavoring and fragrance ingredient and is generally recognized as safe (GRAS) by regulatory bodies for food use at appropriate levels. * Its potential for skin sensitization should be considered in cosmetic and topical product formulations. * While present in some herbal remedies, its therapeutic efficacy and safety for specific conditions are not well-established by clinical trials. *** **Disclaimer:** This information is intended for healthcare professionals.
