# Citral ## Overview Citral is a mixture of two acyclic monoterpene geometric isomers, geranial (trans-isomer) and neral (cis-isomer). It is found naturally in the oils of several plants, including lemon myrtle, lemon verbena, and lemongrass. Citral is primarily used for its flavoring properties and is considered safe for consumption in typical food-grade amounts. ## Primary Indications * Flavoring agent in food and beverages. * Fragrance ingredient in cosmetics and personal care products. * Used in traditional medicine for various ailments, though evidence is often limited. ## Adult Dosing There is no established therapeutic adult dosing for citral as it is generally consumed as a flavoring agent in food. Levels in food are regulated by bodies such as the FDA and EFSA. For use as a fragrance or in traditional preparations, specific dosing is highly variable and lacks standardization. ## Pediatric Dosing There is no established pediatric therapeutic dosing for citral. Its use in pediatric products is typically limited to flavoring or fragrancing at very low concentrations. ## Dose Adjustments Not applicable as citral is not typically used for therapeutic dosing with established adjustments. ## Contraindications * Known hypersensitivity to citral or other components of products containing it. * Use with caution in individuals with sensitive skin, as it can be a skin irritant or sensitizer. ## Adverse Effects * **Skin:** Contact dermatitis, skin irritation, and allergic sensitization are the most common adverse effects, particularly with topical application or prolonged exposure. * **Gastrointestinal:** Generally considered safe in food amounts. Ingesting very large quantities may cause gastrointestinal upset, though this is unlikely in normal use. * **Respiratory:** Inhalation of high concentrations may cause respiratory irritation. ## Key Drug Interactions There are no well-established clinically significant drug interactions reported for citral when consumed in typical dietary amounts. ## Monitoring * For topical applications, monitor for signs of skin irritation, redness, or allergic reactions. * No routine laboratory monitoring is indicated. ## Clinical Pearls * Citral is a common component of "lemon scent" and may be present in various household products. * Individuals with a known allergy to citrus or fragrances should be cautious. * While generally recognized as safe (GRAS) for food flavoring, direct therapeutic use is not standard and lacks robust clinical trial data. *** **Disclaimer:** This information is intended for clinical use and is not a substitute for professional medical advice.
