Health Benefits of Lemongrass Essential Oil
Lemongrass essential oil has long been used in folk medicine to treat ailments ranging from skin infection and joint pains to stress management and digestive issues, and as a disinfectant. In recent years, several studies have empirically proven the beneficial medical properties of the substance.
- Analgesic and Anti-Inflammatory PropertiesA 2010 Japanese joint-study by the Department of Food Science and Nutrition of Nara Women’s University and Department of Bioengineering of Akita Research Institute of Food and Brewing identified that lemongrass oil suppresses COX-2 expression and activates PPARalpha and gamma in cell-based transfection assays which collectively demonstrates the analgesic and anti-inflammatory properties of lemongrass essential oil.
- Treatment in Metabolic Syndrome and Type 2 DiabetesIn a study published by a team from three Austrian universities (University of Vienna, University of Innsbruck and University of Graz) in Biochemical Pharmacology (Volume 92, Issue 1) in July 2014, ‘Natural product agonists of peroxisome proliferator-activated receptor gamma (PPARγ)’, researchers suggest that lemongrass essential oil is capable of improving the metabolic parameters in diabetic animal models with reduced side effects in comparison to full thiazolidinedione agonists. In layman’s term, there is evidence to suggest that lemongrass extracts is more effective in treating diabetes and normalization of blood glucose levels compared to conventional drugs. While further research is obviously warranted, the finding is staggering, to say the least.
- Phytomedicine in psychiatric treatmentsIn a 2006 report (Plants with possible psychoactive effects used by the Krahô Indians, Brazil) the Department of Psychobiology of Sao Paulo State University revealed that Cymbopogon citratus is an effective agent in the treatment of anxiety and nervousness after observing its positive effect in calming agitated patients. In a follow up experiment three years later by the university’s Department of Pharmacology, researchers conclude that lemongrass extracts are also capable of increasing sleeping time.
- Antifungal PropertiesThe Department of Biotechnology of Amravati University, India, in a 2008 study, demonstrated the effectiveness of lemongrass oil in combating Aspergillus fumigatus and Aspergillus niger, the two most common fungal agents affecting humans. Researchers went on to note that their research supports that oils can be used to cure mycotic infections.

Lemongrass essential oil consists chiefly of three active ingredients: Geraniol, Levamisol and p Anisaldehyde.
Geraniol, which comprises up to 67.7% of the compound, is a powerful organic alcohol and monoterpenoid. It is heavily used as a flavoring agent in commercial fruit juices such as grapefruit, watermelon, orange, raspberry and peach. It is however an extremely poor flammable liquid.
Levamisol is a type of hydrochloride salt that is used in drugs for treatments of skin infections and several forms of cancer.
p Anisaldehyde, meanwhile, is a compound that is used extensively in perfumery manufacturing.
How to Identify Good Lemongrass Essential Oil
Owing the prevalence of lemongrass in supermarket aisles, it is actually quite easy to identify good quality lemongrass oil as people can recognize its smell instantly. The light, tangy and earthy citrusy smell of lemongrass is difficult to replicate, so you can immediately spot diluted or flavored ones. Adding chemical aromas also turn the solution less oleaginous.
The oil should always be kept inside dark glass or plastic containers and kept, ideally, in darkened locations. Keeping them in cupboards and shelves, preferably under room temperature, will prolong their lifespan up to two years.
While the oil is not dangerous if consumed internally with tea or food, only do so under supervision. Consult a qualified medical professional if there are any allergic reactions when the oil comes into contact with your skin.
