# Citral ## Overview Citral is a mixture of two acyclic monoterpene geometric isomers, geranial and neral. It is found in the essential oils of many plants, including lemon myrtle, lemon verbena, and lemongrass. Citral has demonstrated various pharmacological activities, including antimicrobial, anti-inflammatory, analgesic, and anticonvulsant effects in preclinical studies. Its use in human medicine is primarily as a fragrance ingredient and flavoring agent. There is limited clinical evidence supporting its use as a therapeutic agent in humans. ## Primary Indications There are no FDA-approved indications for citral. It is used as a flavoring agent and fragrance ingredient. Preclinical studies suggest potential for antimicrobial, anti-inflammatory, and analgesic effects, but these have not been validated in robust clinical trials for therapeutic use. ## Adult Dosing Citral is not used for specific therapeutic dosing in adults. Its concentration in consumer products varies widely and is not standardized for medicinal purposes. ## Pediatric Dosing There is no established pediatric dosing for citral as a therapeutic agent. ## Dose Adjustments Not applicable as there are no established therapeutic doses. ## Contraindications Hypersensitivity to citral or its components. ## Adverse Effects When used in topical products (e.g., cosmetics, perfumes), citral can cause skin sensitization and allergic contact dermatitis in susceptible individuals. Ingestion of large quantities may cause gastrointestinal upset. Data on systemic toxicity from therapeutic use is scarce. ## Key Drug Interactions No significant drug interactions have been established for citral due to its limited therapeutic use. ## Monitoring Monitoring is not applicable as citral is not used for specific therapeutic indications with established protocols. ## Clinical Pearls Citral's therapeutic utility in humans is largely unproven. While preclinical data is promising for certain properties, clinical validation is lacking. Its primary recognized use is as a flavoring and fragrance agent. Practitioners should be aware of its potential to cause skin sensitization in topical applications. *** **Disclaimer:** This information is intended for clinical pharmacy professionals.
