What is Lemongrass Oil?
Lemongrass oil is steam-distilled from the stalks and leaves of the Cymbopogon citratus plant. Its composition is rich in bioactive compounds such as citral, geraniol, myrcene, and flavonoids, which account for its medicinal activity.
This oil features a fresh, lemony scent and is used in aromatherapy, natural remedies, skincare, cleaning products, and even culinary dishes across Asia, Africa, and Latin America.

1. Anti-Inflammatory Properties
Lemongrass oil contains natural anti-inflammatory agents, chiefly citral, myrcene, and quercetin. These compounds help suppress inflammatory mediators in the body, providing relief for conditions such as arthritis, muscular pain, and chronic inflammation.
Studies show that lemongrass oil, when applied topically or used in aromatherapy, can decrease symptoms of joint and muscle pain, potentially making it a helpful adjunct in natural medicine for rheumatoid arthritis and similar disorders.
2. Powerful Antioxidant Effects
Lemongrass oil is loaded with antioxidants, which help neutralize harmful free radicals and reduce oxidative damage linked to aging and chronic diseases.
These antioxidant properties are essential for supporting skin health, regulating cellular activity, and possibly even lowering the risk of certain cancers, according to in vitro studies examining citral and related compounds.
3. Antibacterial and Antifungal Effects
Citral and geraniol in lemongrass oil exhibit potent antimicrobial properties, effective against bacteria (e.g., Staphylococcus aureus, E. coli) and fungi (e.g., Candida).
- Lemongrass oil can be used as a natural remedy to clean wounds, prevent infection, and support treatment of bacterial or fungal skin conditions.
- Topical application shows promise for fungal infections and inflammatory skin diseases.
| Pathogen | Effect of Lemongrass Oil |
|---|---|
| E. coli | Reduced toxicity and bacterial load |
| Staphylococcus aureus | May help treat boils and skin infections |
| Candida spp. | Effective in suppressing fungal growth |
4. Digestive Support and Gut Health
Lemongrass oil is traditionally used in tea and herbal tonics for gut health. Modern research finds lemongrass can help protect the stomach lining, possibly prevent ulcers, ease indigestion, and offer antidiarrheal activity.
- May relieve symptoms of nausea, bloating, spasms, and stomach discomfort.
- Shows potential in safeguarding against gastric irritation and supporting overall digestive health.
5. Cholesterol Regulation
Research indicates lemongrass oil administration (oral or topical) can help lower blood cholesterol in animal studies and traditional medicine.
This appears to support cardiovascular health, though more large-scale clinical studies are needed.
6. Pain Relief and Muscle Relaxation
Lemongrass oil is valued for its analgesic and antispasmodic effects. Topical use may relieve muscular aches, joint pain, and spasms, with some studies indicating improved blood circulation as an added benefit.
Its use in massage blends can help ease tension and discomfort after strenuous activity.
7. Stress Relief and Mood Enhancement
Aromatherapy practitioners recommend lemongrass essential oil for alleviating stress, anxiety, and mental fatigue. Its refreshing citrus aroma is said to uplift mood and promote relaxation, while some studies suggest mild antidepressant-like properties.
8. Skin and Hair Health
Lemongrass oil’s antiseptic, antibacterial, and anti-inflammatory qualities make it excellent for skincare.
- May help reduce redness, swelling, and bacterial infections in acne-prone skin.
- Improves skin elasticity and appearance due to astringent effects.
- Can be used on the scalp to relieve itching, dandruff, and support overall hair health.
9. Hypertension and Heart Health
Lemongrass is traditionally used for managing high blood pressure. Preliminary studies suggest pharmacological potential for blood pressure regulation.
Although research is still ongoing, there’s encouraging evidence for lemongrass oil’s role in promoting cardiovascular health.
10. Insect Repellent and Cleaning Agent
The citrus scent and bioactive profile of lemongrass oil make it a natural insect repellent and household cleaning agent. Its antimicrobial activity helps disinfect surfaces and repel bugs without harsh chemicals.
- Safe for most home cleaning and personal care applications.
- Can be diffused or diluted for topical use in bug sprays.
11. Oral Health Benefits
Some studies explore lemongrass oil’s use in oral hygiene products, noting its potential for treating periodontitis, gingivitis, and oral malodor. Its antimicrobial action fights oral pathogens and may promote fresher breath and healthier gums.
12. May Help Control Blood Sugar
Emerging research suggests lemongrass oil might help regulate blood sugar levels, though more robust evidence is required. This could be promising for people looking for natural metabolic support.
