## Citral Citral is a mixture of two geometric isomers, geranial (trans-citral) and neral (cis-citral). It is primarily derived from the essential oils of plants like lemongrass, lemon myrtle, and lemon verbena. ### Primary Indications Citral is not a recognized pharmaceutical drug with established primary indications for systemic therapeutic use in most regions. It is primarily used as a flavoring agent and fragrance ingredient. Limited research suggests potential topical anti-inflammatory and antimicrobial properties, but these are not established clinical indications. ### Adult Dosing There is no established adult dosing for citral as a pharmaceutical agent. Its use in food and beverages is generally recognized as safe (GRAS) by regulatory bodies within specified limits, which vary by region and food type. ### Pediatric Dosing There is no established pediatric dosing for citral as a pharmaceutical agent. ### Dose Adjustments Not applicable. ### Contraindications Not applicable for pharmaceutical use as there are no established indications. Individuals with known hypersensitivity or allergies to citral or its sources (e.g., certain essential oils) should avoid exposure. ### Adverse Effects When used in food or fragrances at typical levels, citral is generally well-tolerated. However, topical application can cause skin irritation, allergic contact dermatitis, and photosensitivity in susceptible individuals. Ingestion of large quantities may cause gastrointestinal upset. ### Key Drug Interactions No significant drug interactions are documented for citral in a pharmaceutical context due to its lack of established medicinal use. ### Monitoring Not applicable for pharmaceutical use. ### Clinical Pearls Citral is a common component of citrus scents and flavors. While it has potential for topical applications, these are not yet widely supported by robust clinical evidence and require further investigation. Extreme caution should be exercised when considering topical use, especially in sensitive individuals, due to the risk of allergic reactions. --- *Disclaimer: This information is intended for healthcare professionals.
