Cymbopogon nardus
 Citronella essential oil is highly sought after for its symbolism related to energy cleansing. Its environmental sanitizing action also acts as an insect repellent. It can be used as a repellent in the form of an air freshener or in cosmetic form in neutral creams or gels. In the literature, it appears as an aid in the treatment of rheumatism and tendonitis.
