# Citral ## Overview Citral is a mixture of two acyclic monoterpene geometric isomers, geranial (trans-citral) and neral (cis-citral). It is found in the oils of many plants, including lemon, lemongrass, and lemon verbena. It is primarily used as a flavoring agent and fragrance ingredient. Its therapeutic uses are limited and not well-established by robust clinical evidence. ## Primary Indications There are no FDA-approved primary indications for citral as a pharmaceutical agent. It is used in the food and fragrance industries. Some *in vitro* and animal studies suggest potential antimicrobial, anti-inflammatory, and analgesic properties, but these have not translated into established clinical uses. ## Adult Dosing Not applicable for pharmaceutical use. Dosing in food products is typically in the parts per million (ppm) range for flavoring. ## Pediatric Dosing Not applicable for pharmaceutical use. ## Dose Adjustments Not applicable for pharmaceutical use. ## Contraindications Not applicable for pharmaceutical use. Individuals with known hypersensitivity to citral or its components should avoid products containing it. ## Adverse Effects When used in food or fragrances, citral is generally recognized as safe (GRAS) at typical usage levels. However, topical exposure can cause skin irritation and allergic contact dermatitis in susceptible individuals. Ingestion of large quantities, far exceeding typical food use, could potentially lead to gastrointestinal upset, though specific adverse effects from pharmaceutical doses are not established due to lack of use. ## Key Drug Interactions No significant drug interactions are documented for citral in a pharmaceutical context, as it is not typically used as a medication. ## Monitoring Not applicable for pharmaceutical use. ## Clinical Pearls Citral is primarily an ingredient in flavoring and fragrance. While research explores potential biological activities, there is currently no established clinical role or dosing regimen for citral as a therapeutic agent. *** *Disclaimer: This information is intended for healthcare professionals.
