# Citral (3,7-Dimethyl-2,6-octadienal) ## Overview Citral is an acyclic monoterpene aldehyde found in the essential oils of plants such as lemongrass (*Cymbopogon*), lemon myrtle, and orange. It is primarily used as a flavoring agent and fragrance component. It possesses noted antimicrobial, antioxidant, and anti-inflammatory properties in vitro, but it is not currently FDA-approved as a pharmaceutical drug for systemic treatment of any condition. ## Primary Indications There are no established clinical indications for citral as a therapeutic agent. It is categorized by the FDA as "Generally Recognized as Safe" (GRAS) for use as a food additive/flavoring agent. ## Adult Dosing No standardized clinical dose exists. Intake is limited to amounts used for flavoring in food. ## Pediatric Dosing No established pediatric dose. Safety and efficacy in children have not been clinically evaluated for therapeutic use. ## Dose Adjustments Not applicable. Use in patients with hepatic or renal impairment has not been studied. ## Contraindications Hypersensitivity to lemongrass, lemon myrtle, or citral itself. Topical use is contraindicated in individuals with known contact dermatitis or sensitivity to fragrances. ## Adverse Effects * **Dermatologic:** Frequent cause of allergic contact dermatitis; skin sensitization can occur with repeated topical exposure. * **Irritation:** Potential for mucous membrane irritation if inhaled or ingested in high concentrations. * **Gastrointestinal:** Potential for localized irritation if ingested in concentrated forms. ## Key Drug Interactions No major clinical drug interactions documented in humans. In vitro studies suggest potential inhibition of cytochrome P450 enzymes (specifically CYP2C6, CYP2C9, and CYP3A4), which theoretically could affect the metabolism of drugs with narrow therapeutic indices; however, this has not been confirmed in clinical settings. ## Monitoring Not applicable due to lack of medical use. Monitor for signs of allergic reaction (rash, pruritus, or swelling) if used in cosmetic or food applications. ## Clinical Pearls * **Contact Sensitizer:** Citral is listed as one of the fragrance allergens that must be declared on product labels in the European Union if present above certain concentrations. * **Product Quality:** "Citral" found in dietary supplements is often an unregulated extract; lack of standardization makes purity and concentration unpredictable. * **Avoid Therapeutic Reliance:** Do not substitute citral-containing dietary supplements for evidence-based treatments for infections or inflammatory conditions. *** *Disclaimer: This information is for educational purposes only. Citral is not an FDA-approved pharmaceutical agent. Always consult current pharmacological databases (e.g., Lexicomp, Micromedex) or official prescribing information before making clinical decisions. Verify all local protocols regarding the use of natural products and essential oils.*
