• Antibacterial / Antifungal: Studies have shown antibacterial activity, comparable to penicillin. Various studies has shown activity against C albicans, C pseudotropicalis, Mycrosporum gypseum and A niger. Study evaluated the antibacterial properties of alcohol and water extracts. The alcohol extract was generally more effective than the water extract. The presence of alkaloids and phenols were assumed responsible for the antibacterial activity of the extracts.
• Neurobehavioral Effects: Study of myrcene in rats suggests anxiolytic activity. Study of essentail oil produced marked CNS depression in mice, similar to chlorpromazine effect. Also, it increased sleepness time, similar to a thiopental effect.
• Antinociceptive / Analgesic: Myrcene extract from the essential oil has been shown to have an antinociceptive effect.
• Antitumoral: Study showed a-myrcene possess antimutagenic activity in mammary cells. Plant compounds, a-limonene and geraniol showed inhibition of liver and intestinal mucous membrane cancer in mice. Study in Thailand showed inhibition of colorectal neoplasia in mice. Study showed inhibitory effects on early phase hepatocarcinogenesis in rats after initiation with diethylnitrosamine.
• Insect repellent / Insecticidal: Studies of plant oil and powder have shown insect repellent and insecticidal activity. Essential oil has shown activity against Anopheline mosquitos, A culicifacies and A quinquefasciatus and certain developmental phase inhibition of A aegypti.
• Mosquito repellent: Study on the mosquito repellency properties of volatile oils derived from lemongrass (C citratus), citronella grass (cymbopobon nadus) and May chang (Litsea cubeba) against Aedes aegypti and Culex quinquefascitus showed no significant difference on repellency.
• Vascular Smooth Muscle Relaxation Effect: Study evaluated the effects of methanolic extracts of leaves, stems, roots, and citral on vascular smooth muscle using isolated tissue preparations. Citral, leaves, and roots exhibited a dose-dependent relaxant effect on the PE-induced contractions. Citral seemed to partially act via NO. Results suggest the relaxant effect of citral, leaves and roots is endothelium-dependent and may be through its effect on intracelluar calcium concentration. A vasodilator prostaglandin may mediate the effect of leaves.
• Toxicity / Repellent Activity: Essential oils of C. citratus (lemongrass) and Murray koenigii (curry leaf) were tested for toxicity and repellant activity against C. maculatus in stored cowpea. Results showed lemongrass oil to be a more effective contact toxicant on bruchids than curry leaf oil.
• Neurobehavioral Effect of Essential Oil: Study in Swiss male mice of essential oil from fresh leaves produced increase in sleeping time, elevation of seizure threshold and/or blockage of seizure spread. Results suggest sedative/hypnotic, anxiolytic, and anticonvulsant activity.
• Essential Oil / Phytochemical Composition / Antiinflammatory / Analgesic: Study evaluated the anti-inflammatory and gastroprotective effects of C. citratus and Eucalyptus citriodora essential oils on formol-induced edema and acetic acid-induced abdominal cramps in Wistar rats. C. citratus yielded 16 chemical constituents, among which geranial (27.04%), neral (19.93%) and myrcene (27.04%) were major constituents. The oils exhibited significant dose-dependent edema inhibition. Results showed anti-inflammatory activities and a potential role as adjuvant alternative in the treatment of inflammatory-related diseases.
• Antioxidant / Hepatoprotective: Study evaluated the effect of C. citratus against carbon tetrachloride- mediated hepatic oxidative damage in rats. Results showed a hepatoprotective effect attributed to its antioxidant and free radical scavenging property.
• Citral / Housefly (Musca domestica) Control: Study showed the potential of C. citratus oil as an excellent insecticide for housefly control, the results opening up the opportunity for oil/monoterpenes in the development of an eco-friendly, economical, and acceptable product.
• Gastroprotective: Study evaluated C. citratus leaves essential oil for gastroprotection against injuries caused by necrotizing agents (absolute alcohol and aspirin) in rodents. Results showed EOCC reduces gastric damage induced by ethanol, in part, through mechanisms involving endogenous prostaglandins.
• Inhibition of ACF (Aberrant Crypt Foci) in Rat Colon: Study showed lemon grass extract inhibits release of activated aglycon, methylazoxymethanol, from a glucoronide conjugate in the colon, and decreases the DNA adducts and ACF formation in the rat colon.
• Antileishmanial: Study evaluated the inhibitory effect of C. citratus essential oil on Leishmania amazonensis. Results showed a dose-dependent antiproliferative effect of the essential oil on promastigotes and axenic amastigotes. Results showed citral-rich essential oil has promising antileishmanial properties and a potential for a new anti-protozoan drug.
