Chemical composition[edit]

Lemon grass oil contains 65–85%citralin addition tomyrcene,citronellal,citronellol,linaloolandgeraniol.[11][12]Hydrosteam distillation, condensation, and cooling can be used to separate the oil from the water. Thehydrosol,as aby-productof the distillation process, is used for the production of skin care products such as lotions, creams, and facial cleansers. The main ingredients in these products are lemon grass oil and "negros oil" (mixture of lemon grass oil withvirgin coconut oil) used inaromatherapy.[13]

Citronellolis an essential oil constituent fromCymbopogon citratus,Cymbopogon winterianus,andLippia alba.Citronellol has been shown to lower blood pressure in rats by a direct effect on the vascular smooth muscle leading to vasodilation.[14]In a small, randomized, controlled trial, an infusion made fromC. citratuswas used as an inexpensive remedy for the treatment of oral thrush in HIV/AIDS patients.[15]

Laboratory studies have shown cytoprotective, antioxidant, and anti-inflammatory propertiesin vitro.[16][17][18]

Traditional medicinal use[edit]

In thefolk medicineof theKrahôpeople of Brazil, it is believed to have anxiolytic, hypnotic, and anticonvulsant properties.[19][20]
