Lemongrass, also called citronella, is a tall, stalky plant. It’s a common ingredient in Thai cooking and bug repellent. Lemongrass essential oil is used in aromatherapy to freshen the air, reduce stress, and lift your mood. It may even help in balancing cholesterol levels, managing type 2 diabetes, promoting healthy skin, combating fatigue, anxiety, and bad body odor.
Lemongrass is a rich source of flavonoids and phenolic compounds, which contain antioxidants. It’s also an effective antibacterial and antifungal agent that contains anti-inflammatory and antioxidant properties. The antioxidant activity of the lemongrass may boost the immune system and protects against antibiotic-resistant Staphylococcus aureus.
Lemongrass contains quercetin, a flavonoid known for having antioxidant and anti-inflammatory benefits. Quercetin reduces inflammation, which inhibits cancer cell growth and prevents heart disease.
Lemongrass also contains phenolic compounds such as luteolin, glycosides, kaempferol, elemicin, catechol, chlorogenic acid, and caffeic acid. The main component of this fragrant herb is lemonal or citral, which has antifungal and anti-microbial qualities.
Lemongrass is used in Africa as a treatment for coronary heart disease. One study conducted a seven-day treatment of lemongrass extract on rats, which resulted in elevated cholesterol levels decreasing significantly.
In a 2012 observational study, 72 male volunteers were given either lemongrass tea or green tea to drink. Those who drank the lemongrass tea experienced a moderate drop in systolic blood pressure and a mild increase in diastolic blood pressure. They also had a significantly lower heart rate.

Research published in 2011 in Food and Chemical Toxicology journal revealed that the essential oils in lemongrass possess anti-hyperlipidemic and anti-hypercholesterolemic properties that support healthy cholesterol levels.
One animal study has also shown that lemongrass may assist in sustaining healthy levels of triglycerides and reducing LDL. This may help in preventing the accumulation of lipids in the blood vessels and promoting an unobstructed flow of blood in the arteries, thereby preventing various cardiac disorders such as atherosclerosis.
The citral in lemongrass is also thought to have potent anticancer abilities against some cancer cell lines. Several components of lemongrass help fight cancer. This occurs either by causing cell death directly or boosting your immune system so that your body is better able to fight-off cancer on its own.
According to a 2003 animal study, lemongrass may help in cleansing and flushing harmful toxic wastes from the body, as a result of its diuretic properties. Detoxification may help in the regulation of various organs of the body, including the liver and kidneys, while also possibly helping to lower the levels of uric acid. The possible diuretic effect of the herb helps in increasing the quantity and frequency of urination, which helps in maintaining digestive health and detoxifying the body.
Lemongrass tea may help treat oral infections and cavities, thanks to its antimicrobial properties. According to a 2012 in vitro study published by the National Institutes of Health, lemongrass essential oil showed antimicrobial abilities against Streptococcus mutans bacteria, the bacteria most responsible for tooth decay.
Studies have shown that lemongrass essential oil has potentially anti-microbial and anti-bacterial properties which help in fighting the infections caused by pathogens such as Helicobacter pyloriand Escherichia coli. It is beneficial in reducing inflammation and gastrointestinal disorders; it may be helpful to consume to improve digestion and if you suffer from gastric ulcers, constipation, ulcerative colitis, diarrhea, nausea, and stomach ache.
A 2012 study on rodents published by the National Institutes of Health showed that lemongrass may also be effective against gastric ulcers. The study found that the essential oil of lemongrass leaves can help protect the stomach lining against damage from aspirin and ethanol. Regular aspirin use is a common cause of gastric ulcers.
Lemongrass tea is considered to be helpful in calming muscles and nerves that may aid in promoting sleep. Research has shown that lemongrass tea has sedative properties, which can help in increasing the duration of sleep.
Lemongrass is widely used in Ayurvedic medicine for its healing effects in treating cough and cold. Along with other beneficial components, vitamin C in it may help in providing relief from nasal blockages, flu, and other respiratory disorders such as bronchial asthma.
Lemongrass is a febrifuge and is also known as the ‘fever grass’ due to its beneficial effects in lowering fever. The possible antipyretic and diaphoretic effect is extensively used in Ayurvedic medicine for curing fever by inducing sweating.
Lemongrass works as an antiseptic and is effective in treating infections such as ringworm, sores, Athlete’s Foot, scabies, and urinary tract infections (UTI) because of its antimicrobial and anti-fungal properties. Studies have shown that the herb exerts healing effects on dermatological infections, such as yeast infections, by inhibiting the growth of pathogens. Another study provides supporting evidence that demonstrated the efficacy of lemongrass over thyme, patchouli, and cedarwood oil in the treatment of various diseases such as oral or vaginal candidiasis.
Lemongrass and several of its products such as oil are known to be effective against headaches and body aches. A 2018 study suggests that not only is the herbal oil effective against muscle pain and body ache of various kinds, it is also an alternative with lesser side effects as opposed to synthetic drugs. Another study also notes the effective use of lemongrass essential oil against rheumatism, muscle spasms, and cramps.
Lemongrass has been shown to have beneficial implications for managing type-2 diabetes. An animal study published in the Indian Journal of Pharmacology in 2011 indicates that the citral present in the fragrant herb may help maintain optimum levels of insulin and improve the tolerance of glucose in the body.
Lemongrass has been treasured as a skin tonic and makes an effective cleanser for oily or acne-prone skin, due to its astringent and antiseptic qualities. It can help in strengthening the skin tissues and toning up the pores while also sterilizing them.

Lemongrass consists of beneficial essential oils and compounds such as neroli, citronellol, myrcene, dipentene, geraniol, and methyl heptenone. The oil is extensively used in aromatherapy.

How to Buy
The flavorful part of lemongrass is the lower part of the stalks, and it is usually sold with the leaves and upper stalks removed. Look for lemongrass that is firm and pale yellow-green with a bit of a bulb at the end. The top of the stalk should look relatively fresh; they tend to dry out quickly so they may not look like they were just harvested but they shouldn’t be browned.
You can find loose lemongrass tea or lemongrass tea bags at most natural food stores or online.
Herbs and herbal teas aren’t well-regulated, although some pre-packaged herbal teas must follow the U. S. Food and Drug Administration’s labeling laws. To make sure you get a high-quality, pure product, choose organic lemongrass that’s not treated with synthetic pesticides.
How to Store
Store lemongrass loosely wrapped in the fridge for up to several weeks. Or, wrap it well and freeze it. If you’re going to freeze it, consider chopping or mincing it and then freezing it. An ice cube tray is useful for this. Freeze until hard and then transfer to a sealable plastic bag for longer-term storage.
How to Cook
To make lemongrass tea:
- Pour 1 cup boiling water over 1 to 3 teaspoons fresh or dried lemongrass
- Steep for at least five minutes
- Strain the tea
- Enjoy hot or add ice cubes for iced lemongrass tea
Lemongrass is most often used in 1- to 2-inch pieces in soups, stews, and teas. Just add the trimmed pieces of lemongrass stalk and leave them in the soup or stew until it imparts as much flavor as you want. Remove the pieces before serving since they tend to be woody.
Lemongrass can also be minced and added to stir-fries. Use only the bottom few inches for mincing and remove the tough, woody outer layer of the stalk, since that it the most tender part of the lemongrass stalk.
