Therapeutic Properties
Chemistry
Primary Constituents
Citronellal (65-85%), citronellol (4-20%), isopulegol (1-12%), citronellyl acetate (1-5%), beta-caryophyllene (0-2%)
Emotional & Psychological
Emotionally refreshing and mildly sedative, it lifts low mood while calming agitation, supporting those who feel simultaneously overwhelmed and under-motivated. The bright citrus quality uplifts and clears heavy emotional atmospheres while the underlying herbaceous depth helps settle nervous tension, making it useful for summer irritability, heat-related fatigue, and outdoor settings where alertness and calm coexist.
Physical Therapeutic Uses
Well-documented as an insect repellent (PMD derivative is CDC-approved), effective against mosquitoes, ticks, and gnats. Anti-inflammatory citronellal makes it valuable for muscular aches, tendonitis, joint inflammation, and fungal skin conditions including athletes foot. Also used for fever reduction, herpes sores, and cooling heat rashes, and it is commonly blended into outdoor-use sprays and balms for tropical or summer application.
