Summary
Evaluation of lemongrass (Cymbopogon citratus) oil in ointment, cream, and liquid-paraffin bases for topical mosquito repellency against Aedes aegypti.
Key findings
1% solution and 15% cream/ointment preparations gave at least 50% repellency lasting 2-3 hours, attributed to the citral content, comparable to a commercial repellent. Efficacy depended on the base (hydrophilic > emulsion > oleaginous).
Limitations
Bite-deterrence measured on an experimental bird skin model; modest duration; formulation-dependent.
