Other Scientific Studies Relating to Lemon grass

Antimutagenicity of Lemon grass (Cymbopogon citratus Stapf) to various known mutagens in salmonella mutation assay.

A study done in the Department of Biochemistry, Faculty of Medicine, Chiang Mai University, Thailand found that Lemon grass (Cymbopogon citratus Stapf) possess antimutagenic properties towards chemical-induced mutation in Salmonella typhimurium strains TA98 and TA100. Mutagenicity of AFB1, Trp-P-1, Trp-P-2, Glu-P-1, Glu-P-2, IQ, MNNG and AF-2, was inhibited by the extract of lemon grass in a dose-dependent manner, but no effect was found on the mutagenic activity of benzo[a]pyrene.

Lemon grass (Cymbopogon citratus) essential oil as a potent anti-inflammatory and antifungal drugs.

In the present study, lemon grass essential oil was evaluated for its in vivo topical and oral anti-inflammatory effects, and for its in vitro antifungal activity using both liquid and vapor phases
Lemon grass oil extract exhibited promising antifungal effect against Candida albicans, C. tropicalis, and Aspergillus nige. In addition, topical application of LGEO in vivo resulted in a potent anti-inflammatory effect, as demonstrated by using the mouse model of croton oil-induced ear edema.

The effect of lemongrass oil on clinical isolate mastitis pathogens

The aims of this study were to investigate the antibacterial activity of lemongrass oil (LG) and its major components which were citral, geraniol and myrcene, against four strains of clinically isolated bovine mastitis pathogens, including Staphylococcus aureus, The results demonstrate that S. agalactiae and B. cereus are more susceptible to Lemon grass, citral and geraniol than S. aureus and E. coli. Moreover, they also inhibit S. aureus biofilm formation and exhibit effective killing activities on preformed biofilms. The Lemon grass appears to have multiple targets in the bacterial cell, depending on concentration used as well as the amount of its components. Source: Research in Veterinary Science ( Dec 2011)

Activation of intrinsic apoptotic signaling pathway in cancer cells by Cymbopogon citratus polysaccharide fractions.

In the present study, polysaccharides from C. citratus were extracted and fractionated by anion exchange and gel filtration chromatography. Using these polysaccharide fractions F1 and F2, anti-inflammatory and anticancer activities were evaluated against cancer cells in vitro and the mechanism of action of the polysaccharides in inducing apoptosis in cancer cells via intrinsic pathway was also proposed. These polysaccharide fractions exhibited potential cytotoxic and apoptotic effects on carcinoma cells, and they induced apoptosis in these cells through the events of up-regulation of caspase 3, down-regulation of bcl-2 family genes followed by cytochrome c release.

Link of Lemon grass to Cholesterol

The link between lemongrass and cholesterol was investigated by researchers from the Department of Nutritional Sciences, University of Wisconsin, who published their findings in the medical journal Lipids in 1989. They conducted a clinical trial involving 22 people with high cholesterol who took 140-mg capsules of lemongrass oil daily. While cholesterol levels were only slightly affected in some of the participants--cholesterol was lowered from 310 to 294 on average--other people in the study experienced a significant decrease in blood fats. The latter group, characterized as responders, experienced a 25-point drop in cholesterol after one month, and this positive trend continued over the course of the short study. After three months, cholesterol levels among the responders had decreased by a significant 38 points. Once the responders stopped taking lemongrass, their cholesterol returned to previous levels. It should be noted that this study did not involve a placebo group, which is usually used to help measure the effects of the agent being studied (in this case, lemongrass oil).
Neurobehavioral Effects : (1) Study of myrcene in rats suggests anxiolytic activity. (2) Study of essential 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 : (1) Study showed a-myrcene possess antimutagenic activity in mammary cells. (2) Plant compounds, a-limonene and geraniol showed inhibition of liver and intestinal mucous membrane cancer in mice. (3) Study in Thailand showed inhibition of colorectal neoplasia in mice. (4) Study showed inhibitory effects on early phase hepatocarcinogenesis in rats after initiation with diethylnitrosamine.
