# Citral ## Overview Citral is a mixture of two geometric isomers, geranial (trans-citral) and neral (cis-citral). It is a naturally occurring terpene found in the oils of various plants, including lemon myrtle, lemon verbena, and lemongrass. It possesses a strong lemon-like odor and flavor. Its therapeutic uses are primarily based on traditional medicine and limited clinical evidence. ## Primary Indications * **Flavoring agent:** Widely used in food and beverages. * **Fragrance:** Used in cosmetics and perfumes. * **Traditional uses:** Historically used for digestive complaints, insomnia, and pain management, though robust clinical data is lacking for these applications. * **Antimicrobial/Antifungal:** Some *in vitro* studies suggest potential, but clinical relevance is not established. ## Adult Dosing There is no standardized adult dosing for citral in conventional medicine due to a lack of approved indications and extensive clinical trials. Dosing in traditional or complementary medicine contexts varies widely. ## Pediatric Dosing No established pediatric dosing exists for citral. ## Dose Adjustments Not applicable due to lack of standardized dosing. ## Contraindications * Hypersensitivity to citral or any component of the product. * Use with caution in individuals with known skin sensitivities or allergies. ## Adverse Effects * **Dermal:** Skin irritation, allergic contact dermatitis, especially with prolonged or repeated topical exposure. * **Gastrointestinal:** Nausea, vomiting, diarrhea (primarily with high oral doses, which are not typically recommended). * **Respiratory:** Potential for respiratory irritation if inhaled in high concentrations (e.g., essential oils). ## Key Drug Interactions * **CYP450 enzymes:** Limited data, but theoretically, citral may interact with drugs metabolized by cytochrome P450 enzymes. Further research is needed. ## Monitoring * Monitor for signs of skin irritation or allergic reaction with topical application. * Monitor for gastrointestinal upset with oral ingestion. ## Clinical Pearls * Citral is primarily recognized for its flavoring and fragrance properties. * Evidence supporting its use for medicinal purposes is largely anecdotal or from preliminary research. * When used in essential oil formulations, it should be diluted appropriately to minimize skin irritation. *** *This information is intended for healthcare professionals. Always consult the most current prescribing information and relevant literature before making clinical decisions. Local protocols and institutional guidelines may vary.*
