Lemongrass is a tall, perennial grass native to tropical climates in Asia, Africa, and Australia. It is well known in culinary circles—especially in Southeast Asian cuisine—but is also a staple herb in Ayurvedic and folk medicine practices. The herb is sometimes referred to as citronella and is prized for its distinctive lemony scent and subtle, sweet flavor.

- Citral – provides the citrus aroma and has antioxidant properties
- Myrcene
- Limonene
- Geraniol
- Chlorogenic acid
- Isoorientin
- Swertiajaponin
It is also a source of small amounts of micronutrients such as vitamins A and C, folate, potassium, magnesium, calcium, and iron. These natural chemicals contribute to many of its touted health effects.
Top Science-Backed Health Benefits of Lemongrass Tea
Lemongrass tea is used around the world as a traditional remedy for ailments ranging from digestive issues to high blood pressure. Recent research has shed light on its efficacy and the mechanisms behind its perceived benefits.
1. Antioxidant Properties
Lemongrass is rich in antioxidants including chlorogenic acid, isoorientin, and swertiajaponin, which help combat oxidative stress in the body. These compounds protect cells from free radical damage, which is linked to aging and chronic diseases such as heart disease and cancer.
2. Anti-Inflammatory Effects
Lemongrass tea contains compounds with potent anti-inflammatory effects, such as citral and limonene. These may help reduce tissue inflammation and are being studied for their relevance in the management of conditions like arthritis and inflammatory bowel disease.
3. Antimicrobial Activity
Lemongrass tea exhibits antimicrobial properties, capable of fighting certain bacteria and fungi. Studies show lemongrass can inhibit pathogens such as Staphylococcus aureus, Escherichia coli, and Candida albicans. This makes it beneficial for supporting a healthy immune system and preventing infections.
4. Potential Anticancer Benefits
Laboratory research suggests lemongrass may have anticancer properties thanks to its high antioxidant content and compounds like citral. Early evidence indicates it might slow the growth of certain cancer cells, though much more study in humans is needed.
5. Improves Sleep and Promotes Relaxation
Lemongrass tea has been used as a folk remedy for improving sleep quality and reducing stress. It is thought to have mild sedative effects, helping to calm the mind and body and making it a popular choice before bed.

6. Promotes Digestive Health
Lemongrass tea is valued as a traditional digestive aid, reputed to relieve symptoms of:
- Stomach cramps
- Indigestion
- Bloating and gas
- Constipation
- Nausea
Animal studies indicate that lemongrass oil can help protect the stomach lining from damage caused by irritants like aspirin.
7. Natural Diuretic Actions
Lemongrass tea is a known diuretic, increasing urine output and helping to expel excess fluid and sodium from the body. Diuretics are useful for managing fluid retention (edema), heart failure, and liver conditions. Human studies found lemongrass tea led to significantly higher urine output compared to control beverages.
8. May Help Lower Blood Pressure
Several studies have found that lemongrass tea can help reduce systolic and diastolic blood pressure, possibly by promoting vasodilation and decreasing peripheral vascular resistance. Short-term consumption appears effective, though long-term effects may be less pronounced for some individuals.
Key findings from studies:
- Short-term drops in both systolic and diastolic blood pressure after drinking lemongrass tea
- Increase in heart rate and diuresis, especially at higher doses
- Effects tend to diminish over long-term use except at the highest doses
| Parameter | Short-Term Effect | Long-Term Effect |
|---|---|---|
| Systolic Pressure | Moderate decrease | Decreased only at highest dose |
| Diastolic Pressure | Marked decrease | Returns to baseline |
| Heart Rate | Increased | Returns to baseline |
Caution: People with certain heart conditions should use lemongrass carefully due to these effects on blood pressure and heart rate.
9. Supports Healthy Cholesterol Levels
Research suggests lemongrass tea may help reduce total cholesterol and low-density lipoprotein (LDL) cholesterol, especially in animal and in vitro studies. A study on rats showed significant decreases in cholesterol after consuming lemongrass extract, and test tube studies found it may block cholesterol absorption in the gut. More research is needed to confirm these benefits in humans.
10. May Support Anemia Prevention
Lemongrass tea contains iron and other compounds that may stimulate the production of red blood cells. In a human study, regular consumption led to significant increases in hemoglobin, packed cell volume (PCV), and RBC count, suggesting a potential helping role in preventing or managing anemia. White blood cell counts changed in a manner consistent with improved immune health.
11. Potential Aid in Weight Loss
Lemongrass tea is valued as a detox tea and may help with weight loss efforts, primarily through its diuretic effects and as a calorie-free alternative to sugared drinks. While direct scientific evidence is limited, many report anecdotal benefits such as feeling lighter and experiencing reduced bloating.
12. Alleviates Menstrual Discomfort and PMS
Some women use lemongrass tea as a natural remedy for cramps, bloating, and irritability related to menstruation. Its gentle muscle-relaxant and anti-inflammatory effects may help ease period pain and improve mood.
13. Supports Immune Function
Lemongrass contains vitamin C, antioxidants, and antimicrobial compounds that help the body fight infections and support immune health, reducing the risk of common colds and other ailments.

Beyond its health benefits, lemongrass is widely known for its culinary and household applications:
- Flavoring ingredient for soups, curries, and teas, especially in Thai and Vietnamese cuisine
- Aromatherapy and essential oil for stress relief
- Natural mosquito and insect repellent
- Skincare and hair care ingredients
