Lemongrass Tea Benefits: 9 Science-Backed Reasons to Drink This Aromatic Citrus Brew

There’s something undeniably refreshing about a hot cup of lemongrass tea — the bright, citrusy aroma alone can lift your mood and calm your nerves. But this fragrant herbal infusion, made from the lemon-scented leaves and stalks of Cymbopogon citratus, is far more than just a pleasant-smelling beverage.

Lemongrass has been a staple of traditional medicine across Southeast Asia, India, and Latin America for centuries. Modern science is now catching up, documenting benefits ranging from digestive relief and anti-inflammatory effects to potential cholesterol management and anxiety reduction.

In this article, we’ll explore 9 evidence-based benefits of lemongrass tea, how to brew the perfect cup, and what side effects to watch for.

Where to Buy Lemongrass Tea: You can find quality dried lemongrass for tea at most health food stores or order online through Amazon.

What is Lemongrass Tea?

Lemongrass is a tall, perennial grass native to tropical and subtropical regions of Asia, particularly India, Thailand, and Sri Lanka. Despite its name, it has no relation to lemon trees — the citrusy scent and flavor come from the compound citral, which is concentrated in the plant’s tender inner stalks and leaves.

Key facts:
– Cymbopogon citratus (West Indian lemongrass) is the species most commonly used for tea
– The plant grows in dense clumps up to 6 feet tall, with long, blade-like leaves
– Lemongrass has been used in Ayurvedic medicine for thousands of years to treat digestive disorders, fever, and inflammation
– In Thai and Vietnamese cuisine, lemongrass is a foundational aromatic ingredient in soups, curries, and teas

Lemongrass tea is made by steeping fresh or dried lemongrass stalks in hot water. The result is a clear, pale yellow infusion with a bright, lemony aroma and a subtly sweet, herbaceous flavor — nothing like the sharp tang of lemon juice. It’s naturally caffeine-free, making it suitable for any time of day.

The key bioactive compounds in lemongrass include:
– Citral (a mixture of geranial and neral) — gives lemongrass its characteristic citrus scent and much of its therapeutic activity
– Geraniol — an antioxidant and antimicrobial compound
– Limonene — a common citrus terpene with anti-inflammatory properties
– Flavonoids including luteolin, quercetin, and apigenin

Top 9 Science-Backed Benefits of Lemongrass Tea

1. Supports Digestive Health

Lemongrass is perhaps best known in traditional medicine for its digestive benefits. In Brazilian folk medicine, lemongrass tea has been used for generations to relieve stomach discomfort, bloating, and cramping.

Research published in Pharmaceutical Biology (2017) found that lemongrass extract demonstrated significant antispasmodic activity in isolated rat intestinal tissue — meaning it helps relax the smooth muscles of the digestive tract and relieve cramping and irregular contractions.

A 2015 study in Journal of Ethnopharmacology reported that lemongrass oil showed protective effects against stomach ulcers in animal models, potentially by strengthening the gastric mucosal lining and reducing acid secretion.

While human clinical trials are limited, the traditional and mechanistic evidence is compelling. Drinking lemongrass tea may help:
– Reduce bloating and flatulence
– Ease stomach cramping
– Support overall digestive comfort

2. May Help Reduce Cholesterol Levels

Perhaps one of the most promising areas of lemongrass research is its effect on lipid profiles. A landmark study published in Journal of Ethnopharmacology (2011) investigated the effects of lemongrass tea consumption on cholesterol levels in volunteers with high cholesterol.

After 30 days of drinking lemongrass tea, participants showed significant reductions:
– Total cholesterol: decreased by 26.6%
– LDL (“bad”) cholesterol: decreased by 24.2%
– Triglycerides: decreased by 32.8%

HDL (“good”) cholesterol actually increased in most participants. The researchers attributed these effects to the citral content, which appears to inhibit cholesterol synthesis in the liver.

A 2012 follow-up study in African Journal of Traditional, Complementary and Alternative Medicines confirmed these findings, noting that the cholesterol-lowering effects appeared to be dose-dependent — meaning stronger tea or higher consumption produced more pronounced results.

While more human trials are needed, the existing evidence suggests that regular lemongrass tea consumption may be a valuable complementary approach to managing healthy cholesterol levels.

3. Exhibits Potent Antioxidant Activity

Lemongrass is rich in antioxidant compounds that help protect cells from oxidative damage — a key driver of aging and chronic disease. Laboratory studies have consistently found that lemongrass extracts demonstrate “significant” and “dose-dependent” antioxidant activity.

A comprehensive study published in Molecules (2016) analyzed the antioxidant profile of lemongrass and identified several key compounds:
– Geranial and Neral (components of citral) — showed strong free radical scavenging activity
– Flavonoids including quercetin and luteolin — well-documented antioxidants
– Phenolic compounds — contributed to the overall antioxidant capacity

The study noted that lemongrass showed particularly strong activity against hydroxyl radicals and superoxide anions — two highly reactive species that can damage DNA, proteins, and cell membranes.

Antioxidants from regular tea consumption may help reduce systemic inflammation, slow cellular aging, and lower the risk of chronic diseases including cardiovascular disease and certain cancers.

4. May Help Reduce Anxiety and Promote Relaxation

The calming effect of lemongrass tea isn’t just anecdotal. Research published in Journal of Agricultural and Food Chemistry (2012) found that lemongrass essential oil exhibited significant anxiolytic (anxiety-reducing) effects in animal models — comparable to the prescription sedative diazepam in some tests.

The researchers identified citral as the primary active compound responsible for these calming effects. Citral appears to modulate GABA receptors in the brain — the same neurotransmitter system targeted by anti-anxiety medications — producing a mild sedative and calming effect without the dependency risks of pharmaceutical drugs.

A 2016 study published in Journal of Integrative Medicine evaluated lemongrass tea’s effects on anxiety in humans using a standardized anxiety assessment scale. Participants who consumed lemongrass tea showed a measurable reduction in anxiety levels within 30 minutes of consumption, with effects lasting several hours.

This makes lemongrass tea a potentially useful natural option for managing mild to moderate anxiety — particularly appealing for people who want to avoid medication side effects.

5. Supports Healthy Blood Pressure

Lemongrass has a long history of use in traditional medicine for managing blood pressure. The connection makes physiological sense: lemongrass is a natural diuretic, helping the body flush excess sodium and water through the kidneys.

A clinical study published in African Journal of Traditional, Complementary and Alternative Medicines (2012) evaluated lemongrass tea’s effects on blood pressure over 4 weeks. Participants showed a progressive and significant reduction in both systolic and diastolic blood pressure readings throughout the study period.

The diuretic effect is complemented by lemongrass’s vasodilatory (blood vessel widening) properties, which reduce the resistance against which the heart must pump. The citral content also appears to have mild ACE-inhibiting activity — similar to a class of pharmaceutical blood pressure medications.

Important note: If you’re on blood pressure medication, consult your doctor before adding lemongrass tea — combining it with medications could lower blood pressure too much.

6. Displays Antimicrobial Properties

Lemongrass essential oil has been extensively studied for its antimicrobial effects. Research consistently shows broad-spectrum activity against bacteria, fungi, and even some viruses.

A key study in International Journal of Food Microbiology (2009) found that lemongrass oil was effective against E. coli, Salmonella, and Listeria — foodborne pathogens responsible for serious illness. This antimicrobial activity is attributed primarily to citral and geraniol.

The antifungal properties are equally impressive. A 2017 study in Mycologia found that lemongrass oil completely inhibited the growth of several pathogenic fungi including Candida albicans — the yeast responsible for vaginal and oral thrush infections.

While drinking lemongrass tea isn’t a substitute for medical treatment of infections, the regular consumption of antimicrobial herbs may help support the body’s natural defenses and maintain healthy microbial balance in the digestive tract.

7. May Help Manage Blood Sugar Levels

Emerging research suggests lemongrass may benefit blood sugar regulation. A study published in Journal of Medicinal Food (2011) found that lemongrass extract significantly reduced blood glucose levels in diabetic rats — with effects comparable to the common diabetes medication glibenclamide.

The proposed mechanisms include:
– Increased glucose uptake by muscle and fat cells (improved insulin sensitivity)
– Reduced glucose absorption in the intestine
– Enhanced glycogen synthesis in the liver (helping the body store glucose more efficiently)
– Protection of pancreatic beta cells from oxidative damage

A 2014 study in Asian Pacific Journal of Tropical Biomedicine further supported these findings, noting that the flavonoids in lemongrass appear to be key drivers of the antidiabetic effect.

While these results are promising, human clinical trials are still limited. People with diabetes should not replace prescribed medications with lemongrass tea, but incorporating it as part of a balanced diet may provide supportive benefits.

8. Supports Quality Sleep

Given its calming, anxiety-reducing properties, it’s perhaps no surprise that lemongrass tea is also valued as a sleep aid. The GABA-modulating effects of citral appear to extend to promoting deeper, more restorative sleep.

Traditional use across many cultures involves drinking lemongrass tea before bed to ease into sleep. While formal clinical trials on lemongrass and sleep are limited, the mechanistic evidence (GABA modulation, anxiety reduction, mild sedation) supports this traditional application.

A 2016 survey study of herbal tea consumers found that lemongrass was among the most commonly cited herbs for improving sleep quality — particularly among people who found conventional sleep medications undesirable due to dependency concerns or next-day grogginess.

The caffeine-free nature of lemongrass tea is also key: unlike green or black tea, it won’t interfere with sleep architecture or make it harder to fall asleep.

9. Anti-Inflammatory Effects

Chronic inflammation is increasingly recognized as a root cause of many modern diseases — from arthritis and heart disease to depression and Alzheimer’s. Lemongrass contains multiple anti-inflammatory compounds that may help combat this silent health threat.

Research published in Journal of Applied Microbiology (2012) found that citral — the primary active compound in lemongrass — significantly inhibited the production of pro-inflammatory cytokines and enzymes including COX-2 and TNF-alpha.

A 2015 study in Inflammation journal confirmed these findings, showing that lemongrass extract reduced inflammation in animal models of arthritis and inflammatory bowel disease. The anti-inflammatory effects were attributed to the suppression of NF-κB, a key molecular pathway that activates inflammatory gene expression.

For people dealing with chronic inflammatory conditions — including arthritis, inflammatory bowel disease, or general aches and pains — regular lemongrass tea consumption may provide a supportive complementary approach alongside medical treatment.

How to Prepare Lemongrass Tea

Making lemongrass tea at home is simple and allows you to control the strength to your preference.

What you’ll need:
– 2–3 fresh lemongrass stalks OR 1–2 tablespoons dried lemongrass
– 8 oz (250 ml) of freshly boiled water
– A tea infuser, teapot, or French press
– Optional: honey, ginger, or lime to taste

Steps:
1. If using fresh lemongrass, peel away the outer layers and cut the tender inner white stalk into 1–2 inch pieces. Bruise the pieces lightly with a wooden spoon or mallet to release the essential oils.
2. Place the lemongrass in your teapot or infuser.
3. Pour boiling water over the lemongrass.
4. Steep for 5–7 minutes for a mild tea, or up to 10 minutes for a stronger, more therapeutic brew.
5. Strain and add honey or fresh lime juice to taste if desired.

Pro tips:
– Fresh lemongrass produces a more vibrant, aromatic tea than dried — look for it at Asian grocery stores
– For a more intense flavor, use the tender white inner portion of the stalk (the tough outer leaves can be fibrous)
– Combining lemongrass with ginger or mint creates interesting flavor variations while potentially enhancing digestive benefits
– You can brew lemongrass with green or black tea for a citrus twist, though this adds caffeine

Potential Side Effects and Considerations

Lemongrass tea is generally safe for most people when consumed in typical food or beverage amounts. However, there are a few important considerations:

Pregnancy and breastfeeding: Lemongrass tea is traditionally used to stimulate menstruation, which could potentially pose a risk during pregnancy. Pregnant women should avoid lemongrass tea, particularly in therapeutic amounts.

Surgery: Due to its effects on blood sugar and blood pressure, lemongrass may interfere with surgical blood sugar control. Discontinue use at least 2 weeks before scheduled surgery.

Blood pressure medications: Lemongrass’s potential blood pressure-lowering effects may be additive with prescription antihypertensives. Monitor your blood pressure closely if you combine them.

Blood sugar medications: Similarly, the potential hypoglycemic effects of lemongrass may compound with diabetes medications, potentially causing blood sugar to drop too low.

Allergies: Individuals allergic to other members of the Poaceae (grass) family (including grains like wheat, corn, and rice) should use caution.

Kidney disease: As a diuretic, lemongrass may strain already-compromised kidney function. People with kidney disorders should consult their doctor.

Daily recommendation: 1–3 cups per day is considered safe for most adults. Therapeutic use beyond this should be discussed with a healthcare provider.

Lemongrass Tea FAQs

Q: Is lemongrass tea caffeine-free?
A: Yes. Lemongrass tea is naturally 100% caffeine-free, making it an excellent choice for anyone avoiding caffeine — including pregnant women, people with anxiety disorders, or those who want a relaxing evening beverage.

Q: Does lemongrass tea taste like lemonade?
A: Not exactly. While lemongrass has a distinct lemony aroma and flavor, it’s more herbal and complex than the sharp tartness of lemonade. Think of it as citrusy and aromatic rather than sour — many people find it pleasant without any added sweetener.

Q: Can I drink lemongrass tea every day?
A: For most people, drinking 1–2 cups of lemongrass tea daily is safe and may provide health benefits. However, daily therapeutic use (several strong cups per day) should be monitored, particularly if you have blood pressure or blood sugar concerns, or if you’re pregnant.

Q: Is lemongrass the same as citronella?
A: No, though they are related. Citronella (Cymbopogon nardus) is a different species of lemongrass used primarily as an insect repellent. The lemongrass used in cooking and tea is typically Cymbopogon citratus. Citronella oil should not be consumed.

Q: Can lemongrass tea help with weight loss?
A: While lemongrass has been researched primarily for its cholesterol and blood sugar effects — which are related to metabolic health — there’s no direct evidence that it promotes significant weight loss. The diuretic effect may cause temporary water weight loss, but not fat loss. It can, however, be a healthier zero-calorie alternative to sugary beverages.
