Lemongrass Tea Benefits: What the Research Shows and What Shapes Your Results

Lemongrass tea has been part of traditional medicine systems across Southeast Asia, West Africa, and Latin America for centuries. Today it sits comfortably in the growing category of herbal and specialty teas — beverages brewed from plant material other than the Camellia sinensis tea plant. Unlike green, black, or oolong tea, lemongrass tea contains no caffeine and no traditional tea leaves. What it does contain is a complex mixture of plant compounds that researchers have been studying with increasing interest.

This page covers the science behind lemongrass tea — what its key compounds are, what the research generally shows about their effects, and which individual factors shape whether and how those effects might matter to any given person. Because outcomes in nutrition are rarely universal, understanding the variables is just as important as understanding the compounds themselves.

What Lemongrass Tea Actually Is

Lemongrass (Cymbopogon citratus and related species) is a tall, fibrous tropical grass with a distinctively sharp, citrus-like aroma. The tea is typically made by steeping fresh or dried lemongrass stalks or leaves in hot water. It can also be prepared from commercially packaged tea bags containing dried lemongrass.

Within the broader herbal and specialty teas category, lemongrass stands out because its primary aromatic compounds — particularly citral, a naturally occurring mixture of two related molecules called geranial and neral — give it both its characteristic scent and much of its studied biological activity. Most other popular herbal teas derive their character from different compound families: chamomile from apigenin and related flavonoids, peppermint from menthol, ginger from gingerols and shogaols. Lemongrass occupies its own distinct chemical niche.

The preparation method matters. Fresh lemongrass steeped for 5–10 minutes in near-boiling water yields a different concentration of volatile compounds than a bagged tea product or a cold-brew preparation. This isn't a minor detail — bioavailability, the extent to which active compounds actually enter circulation and reach tissues, varies depending on how the tea is prepared, how long it steeps, and even what it's paired with.

The Compounds Behind the Research 🌿

Lemongrass contains several classes of phytonutrients that researchers have studied for their potential physiological effects:

Citral is the dominant volatile compound and the one most associated with lemongrass's biological activity in laboratory settings. Studies have examined citral's interactions with various cellular pathways, particularly those related to oxidative stress and inflammation.

Flavonoids, including luteolin and quercetin, are found in meaningful concentrations in lemongrass. These compounds belong to the broader antioxidant category — substances that can neutralize free radicals, unstable molecules associated with cellular oxidative stress. Antioxidants are a central topic in nutrition research, though the relationship between dietary antioxidant intake and specific health outcomes in humans is complex and still actively studied.

Chlorogenic acid and other polyphenols round out the phytonutrient profile. Polyphenols as a class have been linked in observational research to various markers of metabolic health, though isolating the effects of any single polyphenol-rich food or beverage is methodologically difficult.

Lemongrass tea also contains small amounts of minerals — including potassium, calcium, magnesium, and phosphorus — though the concentrations that actually transfer into brewed tea depend on steeping time, water temperature, and the form of the lemongrass used.

What the Research Generally Shows

It's worth being clear about the state of the evidence before going further. Much of the existing research on lemongrass involves in vitro studies (conducted in cell cultures outside the body) and animal studies. These can generate useful hypotheses about how compounds might behave in humans, but they don't confirm that the same effects occur in people at the concentrations achievable through drinking tea. Human clinical trials specifically examining lemongrass tea are more limited in number and scale.

With that context:

Antioxidant activity is among the most consistently documented properties in laboratory research. Lemongrass extracts have demonstrated free radical scavenging activity across multiple in vitro studies. Whether drinking brewed tea delivers antioxidant compounds in amounts sufficient to meaningfully affect oxidative stress markers in the human body depends on factors that vary from person to person — baseline diet quality, overall antioxidant intake, individual metabolism, and gut microbiome composition.

Anti-inflammatory properties have been studied in both animal models and some early human research. Citral and certain flavonoids have shown the ability to modulate inflammatory signaling pathways in laboratory conditions. Chronic low-grade inflammation is associated in population research with a range of health concerns, which is why anti-inflammatory properties in plant compounds attract significant scientific attention. However, the gap between anti-inflammatory activity observed in a lab and meaningful anti-inflammatory effects from a cup of tea in a human being is substantial — and often not discussed clearly enough in popular coverage of this topic.

Digestive comfort is an area where traditional use and emerging research overlap more directly. Lemongrass has a long history of use for digestive complaints across multiple traditional systems, and some small studies and surveys have found that people report reduced bloating and digestive discomfort with its use. The mechanisms proposed include effects on gut motility and mild antispasmodic activity, though well-controlled human trials are limited.

Antimicrobial properties have been demonstrated against certain bacterial and fungal strains in laboratory settings — particularly for citral. These findings are interesting from a food science and traditional medicine perspective, but they don't translate directly into clinical guidance about what drinking lemongrass tea will do in a human body.

Cholesterol and lipid research includes some small human studies suggesting potential effects on blood lipid profiles with regular lemongrass consumption. These findings are preliminary and have not yet been replicated at the scale needed to draw firm conclusions.

Variables That Shape Individual Outcomes 🔍

Even where research is promising, how lemongrass tea affects any individual depends heavily on variables that no general article can assess.

Preparation method and concentration are among the most underappreciated variables. A cup of lightly steeped bagged lemongrass tea and a strong infusion of fresh stalks are not nutritionally equivalent. Studies that use concentrated extracts may not reflect what's achievable in a typical cup.

Baseline diet quality shapes how much any single food or beverage contributes. Someone eating a diet already rich in diverse polyphenols from fruits, vegetables, and other herbs may see less marginal benefit from adding lemongrass tea than someone whose overall phytonutrient intake is lower.

Age and metabolic function influence how compounds are absorbed, metabolized, and excreted. Older adults and those with certain digestive or liver conditions may process the compounds in lemongrass tea differently.

Frequency and quantity matter. Drinking one cup occasionally is a different nutritional input than drinking several cups daily over months. Most traditional uses and some research protocols involve regular, consistent consumption — not occasional use.

Medications and health conditions are a critical consideration. Citral and other lemongrass compounds may interact with certain medications, including those metabolized by specific liver enzyme pathways. People taking prescription medications, those who are pregnant or breastfeeding, and individuals with hormone-sensitive conditions should discuss herbal tea use with a qualified healthcare provider, since these interactions are not always obvious.

Allergies and sensitivities are relevant for some people. Lemongrass is related to other grasses, and those with grass allergies may respond differently than people without.

Key Questions Within This Topic

Readers approaching lemongrass tea benefits tend to be working through a recognizable set of questions, each of which deserves careful treatment rather than simple answers.

How does lemongrass tea compare to other herbal teas with similar properties? Chamomile, ginger, and peppermint teas each have distinct compound profiles and different bodies of research behind them. Understanding where lemongrass fits — what's unique to its compound profile versus what it shares with other anti-inflammatory or antioxidant-rich herbs — helps put individual benefits in context.

Does drinking lemongrass tea daily make a meaningful difference, and at what quantity? This question sits at the heart of most readers' practical interest. The honest answer involves the state of the evidence (limited large-scale human trials), the variability of individual response, and the difference between statistically observed effects in studies and effects a single person would notice.

What are the safety considerations and who should be cautious? This is often treated as an afterthought in lemongrass tea coverage, but it's foundational. The general safety profile for moderate consumption appears reasonable in the research literature, but specific populations — pregnant individuals, those on certain medications, people with particular liver or kidney concerns — face different considerations.

How does the form of lemongrass matter — fresh, dried, bagged tea, or essential oil? These are not interchangeable. Essential oil preparations, for example, are far more concentrated than brewed tea and carry different safety profiles. The research on extracts doesn't automatically apply to what you'd get from a cup of tea.

What role does lemongrass tea play within an overall dietary pattern? Single-ingredient thinking — the idea that one food or beverage produces health outcomes in isolation — is one of the most persistent problems in nutrition communication. Lemongrass tea, like all foods and herbs, operates within the context of everything else a person eats, how active they are, their stress levels, sleep quality, and overall health status.

Understanding those connections — rather than expecting a single beverage to produce measurable results regardless of context — is ultimately what separates informed use from wishful thinking. The research on lemongrass tea's active compounds is genuinely interesting. Whether that research translates into something meaningful for a specific person depends on factors only that person, ideally working with a knowledgeable healthcare provider or registered dietitian, can fully evaluate.
