Brewed from the tall stalks of Cymbopogon citratus, this caffeine-free herbal infusion has flavored South and Southeast Asian kitchens and Ayurvedic remedies for centuries. The cup delivers a bright, lemony flavor driven by a compound called citral, alongside antioxidants such as chlorogenic acid and luteolin, which is why researchers have spent the past two decades looking at it for digestive, anti-inflammatory, and blood-sugar support. Expect a sip that tastes closer to a clean herbal infusion than to lemonade, with grassy undertones that fade when the stalk is bruised or chopped.
What follows covers the evidence, the recipe, the pairings, and the trade-offs that matter for your daily routine, so you can decide how lemongrass tea fits your goals without guessing.
What Lemongrass Tea Actually Is and Where It Comes From
Every grocery-store stalk of lemongrass started life on a tropical plantation, where farmers harvest the thick, pale lower portion of the grass for cooking and tea. The plant belongs to the Cymbopogon genus, the same family as citronella, which is why crushing a fresh leaf releases that familiar sharp scent.
The Stalk, Not the Leaf, Does the Work
Most recipes call for the lower six inches of the stalk because that section holds the highest concentration of citral, the aromatic compound that gives the cup its lemon-like profile. The tall, blade-like leaves are useful for stocks and marinades but produce a thinner, more bitter brew when steeped on their own.
Inside the stalk, citral works alongside a small group of polyphenols, including chlorogenic acid and luteolin, that researchers have flagged for antioxidant activity. Those compounds survive a standard hot steep reasonably well, which is one reason a five-minute brew still tastes fragrant and feels active in the cup.
Forms You Will Find in Stores
Fresh lemongrass stalks dominate Asian markets and the produce aisle of most US supermarkets. Dried cut pieces and bagged tea dominate the supplement aisle, while instant powders and bottled concentrates sit in the wellness section. The essential oil, which shows up in aromatherapy blends and cleaning products, shares the same citral backbone as the tea but is far more concentrated and never meant to be swallowed undiluted.
How Lemongrass Differs From Citronella
Citronella grass is a close botanical cousin grown mostly for its essential oil, which is used in candles and outdoor sprays. Its flavor is harsher and more camphor-like, so it does not brew into a pleasant cup. When you shop, look for Cymbopogon citratus (West Indian lemongrass) or Cymbopogon flexuosus (East Indian lemongrass) on the label, since both are edible varieties with a clean citrus profile.
With the plant’s identity and label cues sorted, the next question is what controlled research actually shows about what it can and can’t do.
The Evidence Behind the Benefits People Talk About
Antioxidant and anti-inflammatory activity is the strongest signal in the research, driven by citral and a small set of supporting flavonoids. Lab studies and a handful of small human trials suggest these compounds help the body neutralize free radicals and calm low-grade inflammation tied to daily stress, poor sleep, and processed-food-heavy diets.
What the Research Shows, Honestly
Digestive relief and reduced bloating carry moderate support, mostly from animal studies and traditional use, with a plausible mechanism: citral appears to relax the smooth muscle of the gut and reduce gas formation. A mild diuretic effect rounds out the picture, which is why some people notice less puffiness in their hands and ankles after a few days of regular cups.
Preliminary findings on blood pressure, cholesterol, and blood sugar regulation are interesting but early. Most of the human data comes from small trials lasting a few weeks, and much of the cardiovascular evidence is still in animal models. That cautious framing aligns with how the National Center for Complementary and Integrative Health summarizes herbal research, treating these signals as worth watching rather than as settled science.
| Claim | Strength of Evidence | What It Means for You |
|---|---|---|
| Antioxidant and anti-inflammatory | Strong in lab studies, moderate in humans | Likely real, supports general wellness |
| Bloating and digestion | Moderate, mostly traditional use | Useful after heavy meals |
| Blood pressure and cholesterol | Early, mostly animal data | Promising, not a treatment |
| Blood sugar regulation | Early human trials, small samples | Worth a conversation with your clinician |
| Sleep, anxiety, weight loss | Weak or unproven | Skip it for these specific goals |
How to Read the Hype
Marketing copy tends to flatten the gap between a petri dish and a person. A compound that lowers inflammation in cultured cells is not the same as a clinical treatment, and an animal study using concentrated extracts does not translate one-to-one to a cup of tea. The honest read: lemongrass tea is a flavorful herbal infusion with a credible antioxidant profile, useful as one piece of a balanced routine, and not a substitute for medication or medical care.
Lemongrass Tea for Digestion, Weight Support, and Blood Sugar
The folk reputation for settling the stomach has a real basis, mostly because citral appears to relax intestinal smooth muscle and reduce gas formation. Drinking a warm cup after a heavy meal often feels easier on the gut than water alone, especially when the meal was rich or spicy.
The Mild Diuretic Effect
Lemongrass encourages a small increase in urine output, which can drop the scale by a pound or two in the first week without changing body fat. That effect flattens quickly, and the weight returns as soon as hydration normalizes. Treat it as a fluid-shift signal, not a fat-loss result.
Blood Sugar and Diabetes
A handful of small studies indicate that compounds in the stalk may slow post-meal blood sugar spikes by limiting how quickly carbohydrates pass through the gut. A few small human studies have shown modest improvements in fasting glucose and insulin sensitivity, but the samples are too small to draw firm conclusions, and the work has not been replicated in large trials. Anyone managing prediabetes or type 2 diabetes should treat the tea as a complement to dietary changes, movement, and prescribed medication, and should loop a clinician into any new routine.
With the specific blood-sugar caveat flagged, the practical side of things begins: turning those stalks into a reliable daily cup.
Talk to a qualified healthcare professional before adding lemongrass tea to a diabetes or blood-pressure routine, especially if you take medication for either condition. The compounds can interact with the same pathways those drugs target.
Brewing Lemongrass Tea at Home: Fresh, Dried, and Bagged
Fresh stalks produce the brightest cup, dried pieces give a deeper and slightly earthier brew, and bagged tea offers convenience at the cost of aroma. The same principles apply across forms: bruise the plant material, use water just off the boil, and steep for the right window so the cup stays balanced.
The Fresh-Stalk Method
- Trim and wash: Slice off the root end and the dry top of the stalk, peel away any tough outer layers, then rinse under cool water.
- Smash the stalk: Use the flat of a knife or a rolling pin to bruise two to three inches of stalk, which releases the citral.
- Measure and steep: Place the bruised stalk in a mug or pot, pour over 8 ounces of water just off the boil, and steep for 5 to 10 minutes.
- Strain and taste: Pull the stalk out, since longer contact pulls grassy tannins and turns the cup bitter.
Adjusting for Dried and Bagged Forms
Dried cut pieces brew faster and stronger, so a teaspoon per cup with a 5-minute steep is a sensible starting point. Bagged tea follows the package directions, usually one bag per 8 ounces for 4 to 6 minutes. If the cup tastes weak, add 30 seconds to the next steep; if it turns sharp or astringent, shorten the time or drop a quarter-teaspoon of dried material.
Pairings That Earn Their Place
| Add-In | Ratio per 8 oz | What It Brings |
|---|---|---|
| Fresh ginger, sliced | 2 to 3 thin coins | Warmth, extra digestive support |
| Fresh mint leaves | 4 to 5 leaves | Cooling finish, easier drinking in summer |
| Cinnamon stick | 1 small piece | Sweetness without sugar, gentle warming |
| Turmeric, fresh or powdered | ¼ teaspoon powder or 1 inch fresh | Earthy depth, paired anti-inflammatory effect |
| Hibiscus petals | 1 teaspoon dried | Tart color, tangy fruit note |
| Honey or raw sugar | To taste, after cooling slightly | Rounds out the lemongrass, adds body |
Cold-Brew and Iced Versions
For hot weather, drop two bruised stalks or two teaspoons of dried lemongrass into a liter of cold water and refrigerate for 8 to 12 hours. Strain, then pour over ice and add a slice of lime or a few fresh mint leaves. The cold brew tastes smoother than the hot version, with less of the grassy edge that some drinkers pick up in a longer hot steep.
Choosing, Buying, and Storing Lemongrass in Every Form
Fresh stalks should feel firm and heavy for their size, with a pale lower section and a tight, fragrant bulb. Avoid any stalks that look wrinkled, dry at the base, or smell musty, since those have already lost much of their citral content.
Evaluating Dried, Bagged, and Powdered Forms
Dried lemongrass should look pale yellow-green and smell strongly of lemon when you open the bag. Bagged tea is convenient, but check the ingredient list: a short list with lemongrass as the first item usually signals a stronger cup. Instant powders are the most processed option, often mixed with flavorings and sweeteners, so read the label for added sugars and check that the brand tests for heavy metals.
| Form | Shelf Life (Unopened) | Storage After Opening | Best Use |
|---|---|---|---|
| Fresh lemongrass stalks | 1 to 2 weeks refrigerated | Wrap in damp paper towel, place in a sealed bag | Brightest, most aromatic cups |
| Cut and dried lemongrass leaves | 6 to 12 months | Airtight container, cool dark cabinet | Daily brewing, blended infusions |
| Tea bags | 12 to 18 months | Reseal the package, keep dry | Office, travel, quick brew |
| Instant powder | 12 to 24 months | Sealed pouch, dry environment | On-the-go, iced drinks |
| Brewed lemongrass tea | 24 to 48 hours refrigerated | Covered pitcher, cold fridge | Iced and cold-brew use |
Storing Fresh Stalks for the Long Haul
To freeze, chop the stalks into one-inch pieces, flash-freeze them on a sheet pan, then transfer to a freezer bag. Frozen lemongrass keeps its flavor for about six months and drops straight into a pot of simmering water without thawing. Dried lemongrass leaves can be made at home by slicing thinly and air-drying in a low oven, though the result is paler and less aromatic than commercial dried lemongrass.
The Essential Oil Reminder
Far stronger than the brewed cup, the essential oil carries the same aromatic compounds in concentrated form and can scorch the mouth, throat, and stomach lining if swallowed undiluted. Reserve it for diffusers, topical blends (always diluted in a carrier oil), and cleaning sprays, and never substitute drops of oil for brewed stalks in a cup.
Side Effects, Interactions, and a Realistic Daily Dosage
Most people tolerate lemongrass tea well at moderate amounts, but a few mild reactions show up in sensitive drinkers. Heartburn, dizziness, dry mouth, and an increased need to urinate are the most common, usually tied to drinking more than a few cups on an empty stomach.
Who Should Be Cautious
Pregnant or breastfeeding people are generally advised to avoid large amounts, since the diuretic and uterine-stimulating effects of concentrated lemongrass have not been studied thoroughly in pregnancy. People with low blood pressure, hypoglycemia, or a scheduled surgery should also pause and talk to a clinician, since the compounds can amplify the effects of related medications.
Possible Drug Interactions
Lemongrass may interact with diabetes drugs by lowering blood sugar further than intended, with diuretics by compounding fluid loss, with blood pressure medications by amplifying their effect, and with sedatives by adding to drowsiness. Anyone on these medications should clear a new tea routine with their prescribing clinician before starting.
Once the safety baseline is clear, it helps to see how lemongrass actually stacks up against the herbal staples sitting next to it on the shelf.
A Practical Dosage Framework
| Use Case | Typical Amount | Notes |
|---|---|---|
| General wellness | 1 to 2 cups per day | Most studied range, broadly safe for adults |
| Digestive support | 1 cup after heavy meals | Skip on an empty stomach if you get heartburn |
| Upper limit | 3 cups per day | Watch for dizziness, dry mouth, frequent urination |
| Cycling pattern | 2 to 3 weeks on, 1 week off | Suggested by herbal safety sources to reduce tolerance |
| Children | Half-strength cup, occasional | Avoid daily use, no strong safety data |
Stop drinking it and contact a qualified healthcare professional if you notice a rapid heartbeat, persistent dizziness, signs of an allergic reaction, or a sudden drop in blood sugar.
Lemongrass Tea vs. Green Tea and Other Herbal Favorites
Switching from green tea to it trades caffeine for a different polyphenol profile, which changes when and why each one makes sense. Green tea delivers L-theanine alongside a moderate caffeine hit, while lemongrass brings citral and a caffeine-free, citrus-leaning cup.
Caffeine and Antioxidant Comparison
An 8-ounce cup of green tea typically contains 25 to 50 milligrams of caffeine, while a brewed cup of it contains essentially none. Green tea has stronger evidence for heart and metabolic health, supported by decades of research on its catechins. Lemongrass has the edge on anti-inflammatory and digestive effects, with a lighter evidence base but a more relaxed profile for evenings.
| Tea | Caffeine (8 oz) | Key Compounds | Best Time of Day |
|---|---|---|---|
| Lemongrass | 0 mg | Citral, chlorogenic acid, luteolin | Anytime, including evening |
| Green tea | 25 to 50 mg | EGCG, L-theanine, catechins | Morning to early afternoon |
| Chamomile | 0 mg | Apigenin, bisabolol | Evening, before bed |
| Peppermint | 0 mg | Menthol, rosmarinic acid | After meals, late afternoon |
| Ginger | 0 mg | Gingerol, shogaol | Morning, during travel sickness |
When to Reach for Something Else
Chamomile is the better choice for sleep and pre-bed wind-down. Peppermint wins for tension headaches and post-meal bloating driven by sluggish digestion. Ginger pulls ahead for motion sickness, morning nausea, and cold-weather warming. Building a small rotation of two or three caffeine-free options, with lemongrass as the everyday base, usually beats relying on a single infusion for every situation.
Bottom Line
it is a caffeine-free, antioxidant-rich herbal infusion that earns a daily place in most routines, especially when digestion or evening drinking are priorities. One to two cups a day delivers a pleasant, lemony cup with credible anti-inflammatory support, while a small rotation with chamomile, peppermint, or ginger covers the moments lemongrass cannot. Keep dosage moderate, cycle off every few weeks, and loop a clinician in if you take medication for blood pressure, blood sugar, or fluid balance.
FAQ
What is lemongrass tea good for?
it is best known for digestive comfort, mild anti-inflammatory effects, and a gentle diuretic action that can reduce water retention. It is also a flavorful caffeine-free alternative to green or black tea for evening drinking.
Can you drink lemongrass tea every day?
Most healthy adults tolerate one to two cups daily without trouble, though many herbal safety guides recommend a one-week break every two to three weeks. People who are pregnant, take blood pressure or diabetes medication, or have low blood pressure should talk to a clinician first.
Does lemongrass tea help with sleep or anxiety?
it does not contain any known sedative compound, so it will not put you to sleep the way chamomile might. Its caffeine-free profile simply avoids keeping you awake, which can feel like a calming effect later in the day.
Is lemongrass tea better than green tea?
It depends on the goal. Green tea has stronger evidence for heart health, fat oxidation, and cognitive performance, while lemongrass has the edge on digestion, anti-inflammatory effects, and evening drinking. A small rotation of both covers more ground than either alone.
How do you make lemongrass tea from fresh stalks?
Trim and wash a fresh stalk, bruise two to three inches with the flat of a knife, then steep it in 8 ounces of water just off the boil for 5 to 10 minutes. Pull the stalk out before the cup turns grassy, and adjust the steep time up or down by 30 seconds to match your taste.
What does lemongrass tea taste like?
A well-brewed cup tastes bright and lemony, with a clean herbal backbone and a faint grassy edge that fades when the stalk is bruised and steeped briefly. Sweeteners and pairings like ginger or honey round the flavor, while longer steeps push it toward bitter and astringent.
