Lemongrass tea has the kind of résumé that sounds almost suspiciously good: bright citrus flavor, no natural caffeine, a long history in traditional medicine, and a growing collection of scientific studies exploring its antioxidant, antimicrobial, anti-inflammatory, digestive, and cardiovascular effects. It also smells like someone somehow turned a tropical garden into a cup of tea.
Made primarily from Cymbopogon citratus, lemongrass tea is an herbal infusion rather than a true tea from the Camellia sinensis plant. That distinction matters because plain lemongrass tea is naturally caffeine-free. It also contains plant compounds such as citral, flavonoids, phenolic compounds, and other phytochemicals that researchers have investigated for possible health effects.
Still, there is an important word in the title of this article: potential. Laboratory experiments and animal studies have produced interesting results, while human clinical research remains comparatively limited. Lemongrass tea may be an enjoyable addition to a healthy diet, but it is not a magic potion, a detox shortcut, or a replacement for medical treatment.
What Is Lemongrass Tea?
Lemongrass is a tall tropical grass widely used in Southeast Asian cooking, especially in Thai and Vietnamese dishes. Fresh stalks have a lemon-like fragrance without being especially sour. The leaves and stalks can also be dried or used fresh to prepare a fragrant herbal infusion.
Unlike black, green, white, and oolong teas, pure lemongrass tea does not contain caffeine. That makes it particularly attractive to people who enjoy a hot beverage in the evening or want to reduce their coffee intake without spending the afternoon staring sadly at a mug of plain hot water.
Much of the scientific interest in lemongrass centers on citral, an aromatic compound responsible for much of the plant’s characteristic scent. Lemongrass also contains polyphenols and flavonoids that can act as antioxidants in laboratory experiments.
Potential Benefits of Lemongrass Tea
1. It Provides Antioxidant Plant Compounds
One of the better-established characteristics of lemongrass is its collection of antioxidant compounds. Researchers have identified phenolic compounds and flavonoids capable of interacting with unstable molecules known as free radicals.
Free radicals are produced naturally during metabolism and can also increase in response to factors such as pollution, tobacco smoke, and ultraviolet radiation. When their production overwhelms the body’s antioxidant defenses, oxidative stress can damage cells and tissues.
This does not mean that a cup of lemongrass tea will suddenly place an invisible antioxidant force field around your organs. Human health is considerably more complicated than a laboratory antioxidant test. Still, consuming a varied diet rich in plant foods is associated with numerous health benefits, and an unsweetened herbal tea can fit comfortably into that pattern.
2. Lemongrass Has Anti-Inflammatory Potential
Scientists have also investigated citral and other lemongrass compounds for anti-inflammatory activity. Laboratory and preclinical studies suggest that some of these compounds may influence chemical pathways involved in inflammation.
That finding attracts attention because chronic inflammation is associated with cardiovascular disease, metabolic disorders, arthritis, and many other conditions. However, showing an anti-inflammatory effect in cells or animals is not the same as demonstrating that ordinary lemongrass tea treats inflammatory disease in humans.
The practical conclusion is more modest: lemongrass contains biologically active compounds worth studying, but drinking the tea should complement rather than replace proven approaches such as a balanced diet, physical activity, adequate sleep, and prescribed treatment when necessary.
3. It May Support Cardiovascular Health
Blood pressure is one of the most interesting areas of lemongrass research. Reviews of available studies describe potential vasorelaxant effects, meaning certain lemongrass compounds may help blood vessels relax. Small human studies have also reported changes in blood pressure and heart rate after consuming lemongrass preparations.
Some research has observed reductions in systolic blood pressure, while other findings are less consistent. Scientists still need larger, well-controlled clinical trials to determine how significant the effect is, what dose might be appropriate, and whether benefits continue with regular consumption.
There is another simple cardiovascular advantage that does not require exotic biochemistry: plain lemongrass tea is caffeine-free. People who experience temporary blood pressure increases, palpitations, or jitteriness after caffeine may find that replacing one caffeinated drink with lemongrass tea works better for them.
That does not make lemongrass a hypertension treatment. Anyone taking blood-pressure medication should be especially careful about regularly consuming large amounts of herbs advertised for lowering blood pressure.
4. It May Have a Mild Diuretic Effect
Lemongrass has traditionally been described as a natural diuretic, and both human and animal research has reported increases in urine production under some circumstances.
A mild diuretic effect could theoretically help the body eliminate additional water and sodium. Unfortunately, the internet occasionally turns this observation into enthusiastic promises about “detoxing,” rapid weight loss, or melting belly fat. Your kidneys may reasonably object to this marketing department.
Losing water is not the same as losing body fat, and increased urination is not proof that toxins are being magically flushed away. The liver and kidneys already perform the body’s major detoxification work around the clock.
Importantly, research using larger or prolonged doses of lemongrass preparations has raised concerns about changes in kidney-related laboratory measurements. More is not necessarily better.
5. Lemongrass Tea May Be Friendly to Digestion
Lemongrass has a long history of traditional use for stomach discomfort, cramps, indigestion, and other gastrointestinal complaints. This history has encouraged researchers to examine possible protective effects in the digestive system.
Animal studies have suggested that lemongrass preparations may help protect the stomach lining under certain experimental conditions. Antimicrobial compounds in the plant have also shown activity against various microorganisms in laboratory settings.
Human evidence specifically demonstrating that lemongrass tea treats ulcers, reflux, food poisoning, irritable bowel syndrome, or other gastrointestinal diseases is lacking. Nevertheless, an unsweetened warm beverage may feel soothing after a meal, and replacing sugary beverages with herbal tea can be a sensible dietary change.
6. It Has Demonstrated Antimicrobial Activity in Research
Lemongrass extracts and essential oil have demonstrated antibacterial and antifungal effects in laboratory research. Scientists have investigated activity against several organisms, including some bacteria associated with dental plaque and tooth decay.
Small clinical studies involving lemongrass-containing mouth rinses have also explored possible benefits for plaque, gingivitis, oral odor, and certain oral microorganisms.
There is a major qualification, however: mouthwash, concentrated extract, essential oil, and brewed tea are not interchangeable products. Finding antimicrobial activity in lemongrass essential oil does not prove that sipping lemongrass tea cures an infection.
Never drink lemongrass essential oil as though it were concentrated tea. Essential oils contain far higher concentrations of active compounds and can cause adverse effects when used incorrectly.
7. It Could Offer a Useful Caffeine-Free Alternative
This may be one of the least glamorous but most practical lemongrass tea benefits.
People often focus on finding extraordinary properties inside a beverage while overlooking what the beverage replaces. A mug of unsweetened lemongrass tea contains little or no meaningful amount of sugar and no natural caffeine. If it replaces a large sweetened coffee, soda, energy drink, or dessert-like beverage, the nutritional difference can become meaningful over time.
Someone consuming two 200-calorie specialty drinks every day could substantially reduce calorie and added-sugar intake by replacing even one with unsweetened herbal tea.
For people sensitive to caffeine, switching their evening drink may also help avoid caffeine-related insomnia. Better sleep has health benefits considerably better established than most dramatic claims made about herbal “detox” beverages.
8. Lemongrass May Have Metabolic Effects, but Evidence Is Limited
Online discussions sometimes claim that lemongrass tea lowers cholesterol, controls blood sugar, or accelerates metabolism. These statements need considerable caution.
Animal experiments have reported cholesterol-related changes after administration of certain lemongrass extracts. However, an older human clinical study examining lemongrass tea did not find meaningful changes in cholesterol, triglycerides, or blood glucose during its relatively short observation period.
That is a useful reminder of how nutrition headlines are born. A promising rodent study becomes “may lower cholesterol,” which becomes “lowers cholesterol,” which eventually becomes a social-media post telling you that cardiologists hate this one weird grass.
Current evidence does not justify using lemongrass tea instead of cholesterol medication, diabetes treatment, or established dietary strategies.
9. What About Anxiety and Relaxation?
Lemongrass has traditionally been used as a calming herb. Its fragrance is also popular in aromatherapy.
Recent small studies of lemongrass aroma have found possible reductions in anxiety during stressful situations such as dental treatment. Other research involving oral lemongrass tea, however, has failed to demonstrate convincing sedative or anxiety-reducing effects.
This distinction is important. Evidence involving inhaled essential-oil aroma cannot automatically be applied to drinking tea.
Even without a pharmacological sedative effect, preparing a warm caffeine-free beverage can become part of a relaxing evening routine. The benefit may come partly from the ritual: turning off the laptop, making tea, sitting somewhere comfortable, and doing absolutely nothing revolutionary for ten minutes.
Claims About Cancer Require Extra Caution
Citral and other compounds derived from lemongrass have been studied against cancer cells in laboratory experiments. Certain studies have observed effects on cellular pathways related to cancer-cell growth or death.
These experiments are scientifically interesting but should not be interpreted as evidence that drinking lemongrass tea prevents or treats cancer.
Concentrations used in cell experiments may differ dramatically from anything achievable through ordinary tea consumption, and compounds that affect isolated cells do not necessarily produce the same effects inside the human body.
People undergoing chemotherapy, radiation therapy, immunotherapy, or other cancer treatment should discuss herbal products with their oncology team rather than adding concentrated lemongrass products independently.
Possible Side Effects of Lemongrass Tea
Lemongrass consumed in ordinary culinary amounts is generally well tolerated by many adults, but herbal does not mean risk-free.
Reported or proposed side effects can include dizziness, dry mouth, tiredness, stomach discomfort, increased urination, and allergic reactions. People allergic to lemongrass or related plants should avoid it.
High doses and prolonged use deserve more caution. Some human research involving relatively large daily amounts has identified changes in creatinine, urea, estimated kidney filtration, or other measurements that warrant further investigation.
Who Should Be Especially Careful?
- Pregnant people: Medicinal amounts of lemongrass are generally discouraged because pregnancy safety has not been adequately established.
- People taking diuretics: Combining medications that increase urination with large amounts of lemongrass could potentially amplify effects on fluids or electrolytes.
- People taking blood-pressure medicine: Because lemongrass may affect blood pressure, regular medicinal use should be discussed with a healthcare professional.
- People with kidney or liver disease: Concentrated products or frequent high-dose consumption may be inappropriate.
- People using multiple medications: Herbal-drug interaction information for lemongrass is incomplete, making professional guidance sensible.
Dietary supplements and concentrated herbal products are also regulated differently from prescription drugs in the United States. A supplement appearing on a store shelf does not mean the FDA has approved it for effectiveness before sale.
How to Make Lemongrass Tea
Preparing lemongrass tea does not require specialized equipment, a wellness retreat, or a $79 ceramic device advertised by an influencer.
- Wash fresh lemongrass thoroughly if you are using fresh stalks.
- Remove damaged outer layers and cut or gently crush the softer portions to release their aroma.
- Place the lemongrass in a mug or teapot.
- Add freshly boiled water.
- Allow it to steep for approximately 5 to 10 minutes, depending on the strength you prefer.
- Strain and serve.
You can drink it hot or chill it over ice. Ginger, mint, or a small squeeze of lemon can add flavor. If health is your priority, avoid turning the tea into liquid candy with several spoonfuls of sugar.
There is no scientifically established therapeutic dose of lemongrass tea for treating disease. For routine beverage use, following the product’s preparation instructions and consuming moderate amounts is more reasonable than assuming that an extra-strong brew must be extra healthy.
Fresh Lemongrass vs. Tea Bags
Both can work well. Fresh lemongrass provides a vivid citrus aroma and gives you more control over strength. Dried tea bags are convenient and consistent.
When buying packaged lemongrass tea, check the ingredient list. Some blends contain green or black tea and therefore contain caffeine. Others include licorice root, sweeteners, or additional herbs that have their own benefits, risks, and medication interactions.
Choose products from reputable companies with clear labeling rather than mysterious powders claiming to “detox 17 organs before breakfast.”
What the Research Really Says
The overall evidence on the potential benefits of lemongrass tea can be summarized fairly simply.
Reasonably supported: Lemongrass contains antioxidant and biologically active plant compounds, and plain lemongrass herbal tea is naturally caffeine-free.
Promising but not proven: Small studies and preclinical research suggest possible effects involving blood pressure, inflammation, antimicrobial activity, digestion, and urine production.
Weak or insufficient evidence: Claims that lemongrass tea reliably lowers cholesterol, causes meaningful fat loss, treats anxiety, prevents cancer, cures infections, or replaces medications.
That does not make lemongrass tea useless. A beverage does not need pharmaceutical powers to deserve a place in your kitchen.
Experiences With Lemongrass Tea: What Regular Drinkers May Notice
The practical experience of drinking lemongrass tea is considerably less dramatic than some wellness advertisements suggest, and that is actually part of its appeal.
The first noticeable feature is usually the aroma. Freshly bruised lemongrass releases a clean citrus fragrance that resembles lemon peel but with softer herbal notes. Despite the smell, the brewed tea is generally not sharply acidic. People who dislike sour lemon water may therefore find lemongrass surprisingly easy to drink.
Strength changes the experience significantly. A lightly steeped cup can be delicate and almost floral. A longer steep produces a stronger grassy, citrus character that some people love and others describe as suspiciously close to drinking a well-maintained lawn. Starting with a mild brew makes sense.
Using Lemongrass Tea as a Coffee Replacement
One of the most realistic experiments is replacing a late-afternoon coffee with lemongrass tea for a week or two.
The biggest difference is not necessarily a medicinal effect from lemongrass. It is the absence of caffeine. Someone accustomed to drinking coffee at 4 p.m. may discover that falling asleep feels easier after switching to a caffeine-free herbal drink.
People who consume substantial amounts of caffeine should reduce it gradually. Abruptly replacing several daily coffees with herbal tea can cause headaches, fatigue, and irritability. Those symptoms come from caffeine withdrawal, not because lemongrass has personally declared war on your productivity.
Drinking It After Meals
Another common experience is enjoying lemongrass tea after dinner. Its fresh flavor can make it an appealing substitute for dessert beverages or alcohol, and some people report that a warm cup feels comfortable after a heavy meal.
It is reasonable to enjoy that sensation, but personal digestive comfort should not be confused with evidence that the tea treats a gastrointestinal disorder. Persistent abdominal pain, vomiting, unexplained weight loss, gastrointestinal bleeding, or severe indigestion deserves medical evaluation rather than a stronger pot of tea.
Trying It Hot and Iced
People who find herbal tea boring when served hot may have a completely different experience with iced lemongrass tea.
Steep the tea slightly stronger than usual, cool it, and pour it over ice. Fresh mint or ginger can make the flavor more interesting without adding much sugar. Preparing a pitcher in advance can also make an unsweetened beverage easier to grab than soda.
This is where lemongrass tea can deliver a practical long-term benefit: beverages are habits. If an enjoyable unsweetened tea replaces one sugary drink each day, the resulting reduction in added sugar can matter far more than chasing an unproven “fat-burning” compound.
Pay Attention to Your Own Response
People respond differently to herbs. Someone may comfortably drink lemongrass tea several times a week while another person experiences stomach irritation or increased urination after one strong cup.
If you are experimenting with it, change one thing at a time. Try a moderate serving rather than immediately drinking a giant thermos every day. Pay attention to dizziness, unusual fatigue, digestive symptoms, allergic reactions, or changes that could matter if you take medication.
If you are measuring blood pressure at home, do not change prescribed treatment based on a few readings after drinking tea. Blood pressure naturally fluctuates throughout the day. Reliable conclusions require appropriate measurement techniques and professional medical guidance.
The Most Sustainable Experience Is Usually the Simplest
The people most likely to keep drinking lemongrass tea are probably not those expecting a miraculous transformation in seven days. They are the people who enjoy the flavor.
That may sound disappointingly ordinary, but ordinary habits are often powerful. A pleasant caffeine-free drink can help someone reduce soda, avoid late-night caffeine, drink more fluids, or build a relaxing evening routine.
Those benefits may not make an exciting advertisement, but they are realistic, inexpensive, and considerably easier to defend scientifically.
Conclusion: Is Lemongrass Tea Worth Drinking?
For most healthy adults who tolerate it, lemongrass tea can be a flavorful addition to an otherwise balanced diet. It provides naturally occurring plant compounds, is generally caffeine-free when served without traditional tea leaves, and has generated promising research involving antioxidant activity, inflammation, blood pressure, antimicrobial effects, digestion, and diuresis.
However, the clinical evidence is not strong enough to promote lemongrass tea as a treatment for hypertension, high cholesterol, diabetes, infections, anxiety, cancer, or other medical conditions.
Its greatest advantages may actually be wonderfully unexciting: it tastes refreshing, contains no natural caffeine, can be served without sugar, and offers an easy alternative to calorie-heavy beverages.
Enjoy the tea because you like it. Consider the possible health benefits a bonus rather than a prescription.
Note: This article is intended for general educational purposes and does not replace individualized medical advice. People who are pregnant, have kidney or liver conditions, take prescription medications, or plan to use concentrated lemongrass products regularly should discuss their use with a qualified healthcare professional.
