Central Nervous System
Lemongrass is a “nervine” – a herb that specifically supports the nervous system to combat symptoms of stress and anxiety. It lowers levels of stress hormones and acts as a tonic for frazzled nerves, making it beneficial in the treatment of various nervous disorders such as vertigo and uncontrollable shaking.
The calming properties of Lemongrass make it very helpful in promoting a good night’s sleep, especially where stress and anxiety are the cause of sleepless nights. It helps to soothe the mind and body by inducing the release of serotonin, the pre-cursor to the sleep hormone melatonin. One study published in the "Journal of Alternative and Complimentary Medicine" found that when subjects were exposed to a situation that caused anxiety, the group who were exposed to the scent of Lemongrass essential oil experienced a significant decrease in anxiety immediately after treatment. A cup of Lemongrass tea or diffusing the essential oil in your bedroom can help you to relax and wind down in readiness for sleep.
Digestive System Support
Used for thousands of years in ancient medicinal systems as a digestive aid, Lemongrass contains the compound citral which enhances nutrient absorption and helps to maintain healthy metabolism. The antioxidants present in this herb support a healthy environment for good bacteria to thrive in the gut by preventing the growth of yeast and other bad bacteria.
The strong anti-microbial and antibacterial properties of Lemongrass are also helpful in fighting stomach disorders caused by various pathogens. One study found that Lemongrass leaves can help to protect the stomach lining from damage by aspirin and alcohol – a common cause of gastric ulcers.
Fever Reducer/Immune Boosting
Lemongrass has been used for millennia as a fever reducer in its native countries. It is classed as a “febrifuge” – a medicine to reduce fever – and has an anti-pyretic and diaphoretic effect, meaning it helps to break a fever that has run to dangerously high temperatures by inducing sweating.
The natural immune boosting qualities of Lemongrass are attributed to its ability to reduce pro-inflammatory cytokines in the body, which can contribute to illness.
Diffusing Lemongrass essential oil in an oil burner has also been found to combat airborne viruses that can cause the common cold and flu.
Type II Diabetes
The high citral content of Lemongrass is responsible for its many benefits; it helps to maintain healthy insulin levels in the body, thus supporting better glucose tolerance. A 2007 study published in the "Journal of Ethnopharmacology" found that taking Lemongrass daily improved fasting glucose levels, cholesterol levels and led to lower triglyceride levels. The study concluded that more research is needed but advised caution to those taking diabetes medication to consult their doctor before consuming high amounts of this herb.
Because of its powerful anti-microbial, antibacterial and anti-fungal properties, Lemongrass essential oil (diluted in a carrier oil) has been proven effective in the treatment of conditions such as; athlete’s foot, ringworm, scabies and yeast infections. Studies have shown that the properties of Lemongrass inhibit the growth of pathogens, and that the key compound citral is effective at reducing fungal infections - especially those caused by the Candida albicans fungus.
Lemongrass has a long history as a natural ingredient for skincare. Its antiseptic and astringent properties make it ideal for use as a natural cleanser and toner, sterilising and toning up the pores whilst strengthening the skin. Its diuretic properties can reduce puffy skin and cellulite when the oil is diluted in a carrier oil and applied to the affected area.
Healthy Weight Loss
Lemongrass contains polyphenolic compounds that work to stimulate metabolism, allowing the body to burn fat more efficiently whilst boosting energy levels. It is also a natural diuretic that will help the body flush out excess water, eliminating excess fluid retention whilst gently detoxifying the liver and kidneys.
Its star compound, citral, has been found to be effective in combating obesity, preventing the accumulation of abdominal fat and promoting the use of stored energy. Replacing caffeine laden beverages with a cup of refreshing Lemongrass tea can go a long way as part of a healthy weight loss plan.
Lemongrass Essential Oil
Lemongrass essential oil is an extremely versatile oil that has a myriad of uses. It has antibacterial, antifungal and anti-inflammatory properties, making it useful for skin infections and a powerful deterrent against fungal infections.

Natural Insect Repellent
One of the most famous uses of Lemongrass essential oil is as an effective and natural insect repellent. It is thought that the citronella content of Lemongrass is responsible for its insect repelling abilties. It blocks the scent that attract mosquitoes and other biting insects such as lactic acid and carbon dioxide, making it harder for insects to locate you. Furthermore, research has shown that citronella helps to reduce mosquito landing by 40 percent.
Folklore and history
