Lemongrass (Cymbopogon citratus) is one of the most neglected medicinal plants of Indian medicine and is popularly known as chai wali ghaas, gavti chaha or simply lemongrass in India. While not as popular as ashwagandha or as well-known as turmeric, lemongrass tea benefits are still quite significant.
The lemongrass tea is a surprisingly easy recipe: The stems or dried leaves of lemongrass are steeped in hot water for 5-10 minutes and then optionally garnished with ginger, honey, or lemon. The infused liquid is light golden, fresh and very citrus-floral. With a bioactive compound profile that only few herbs can match, the health benefits of lemongrass tea include antimicrobial defense, antioxidant protection, digestive support, anxiety relief, blood sugar regulation and more.
This comprehensive article explains the 7 most clinically backed benefits of lemongrass tea, how water lemon grass tea contributes to weight loss and the truth about the side effects of lemon grass tea.
What Makes Lemongrass Tea Work? Phytochemical Profile
All the health promoting properties of lemongrass tea can be attributed to its very high phytochemical content, which is rich in terpenoids, flavonoids and phenolic acids. The main bioactive compounds are:
- Citral (neral + geranial): 65-85% of lemongrass essential oil. A potent antimicrobial, anti-inflammatory, anti-allergic and anti-anxiety agent. The most striking smell and the most prominent therapeutic compound.
- Limonene is an anti-inflammatory and anti-cancer terpenoid.
- Cymbopogon martini: Analgesic and muscle relaxation
- Geraniol and Linalool: Anti-microbial and have calming/sedative properties.
- Lemon grass antioxidant properties are significant because of the presence of chlorogenic acid which plays a key role in the blood sugar lowering effect of lemon grass tea.
- Isoorientin and Orientin are C-glycosyl flavones, antioxidants, anti-inflammatory agents and cholesterol-lowering agents.
- Quercetin and Luteolin are anti-inflammatory flavonoids.
- The nutrients include potassium, calcium, magnesium, iron, zinc and Vitamin C.
It’s this thick terpenoid-flavonoid matrix – especially citral and the C-glycosyl flavones – that make the lemongrass tea benefits so pharmacologically diverse, and so well-supported across multiple body systems, at the same time. The majority of herbal teas provide antioxidants and nice flavor. Lemongrass tea provides that and a really refined assortment of bio-herbs.
7 Proven Lemongrass Tea Benefits: -
- Powerful Antioxidant Protection That Fights Chronic Disease at the Root
The first and most basic of all the Lemongrass tea benefits is its outstanding antioxidant activity. It is a combination of isoorientin, orientin, chlorogenic acid, quercetin and luteolin, which provides a multi-compound antioxidant network that neutralises reactive oxygen species (ROS) in several cellular compartments at once. Oxidative stress – the imbalance between free radical production and the ability to defend against them – is the common upstream cause of almost all chronic diseases – cardiovascular diseases, cancer, diabetes, neurodegeneration and accelerated ageing.
According to the study published in Food Chemistry, lemongrass extract proved to have much greater antioxidant activity than other regular herbal teas used in ORAC and DPPH assays. These health benefits of lemongrass tea, from an antioxidant perspective, are therefore not only theoretical, but are directly measurable and are comparable to or greater than well-known herbal antioxidant beverages, and without the tannin-related astringency nor caffeine load of green tea or black tea.
- Reduces Anxiety and Promotes Calm Mental State
One of the most beneficial lemongrass tea effects for contemporary urban living is its anxiolytic property, which indicates its capability to lessen anxiety. The major one is the modulation of the GABAergic system: Gamma-aminobutyric acid (GABA) is the most abundant inhibitory neurotransmitter in the brain and it is the one that is responsible for decreasing the excitability of the neurons and inducing calmness. In preclinical studies, citral and linalool were both found to enhance the activity of GABA receptors, which is known to produce a calming effect without the sedation or dependency effects seen with pharmaceutical anxiolytics.
One of the most practical and evidence-based uses of this anti-anxiety effect — especially in the evening, when you are winding down for bed — is making lemon grass tea a part of your bedtime regimen, rather than relying on traditional sedatives that can cause grogginess the following morning, or dependency.
- Supports Digestive Health and Relieves Bloating
Lemongrass tea offers a range of health benefits for digestion, many of which are multi-mechanistic and immediately practical. Citral and myrcene have shown anti-spasmodic effects which will diminish the involuntary movement of the GI tract leading to an uncomfortable irritable bowel syndrome, bloating and cramping. Lemongrass also encourages digestive enzyme production, which helps to break down food and decreases the fermentation of poor food digestion leading to gas. It has a mild diuretic effect and is useful at reducing the amount of water that accumulates in the body, which is responsible for abdominal bloating.
Lemon grass is commonly used in digestive ailments along with ginger and honey throughout India, South East Asia and West Africa, where the combination works synergistically to enhance the digestive properties of lemon grass. One of the most widely reported traditional uses of lemon grass tea is for digestive problems after eating large amounts of heavy, oily food, following its use in every culture where it is found.
- Water Lemon Grass Tea for Weight Loss:
Often one of the most googled uses of lemon grass is for weight loss, and although the proof isn't as substantial as that of other weight management herbs that have received more attention, the results are promising when it comes to multiple mechanisms:
Diuretic action:
Lemongrass has a long history of being used as a natural diuretic. One advantage of regular lemon grass tea consumption is that it causes a mild, steady reduction in water retention that helps to prevent bloated appearance, which can make the difference when it comes to actual weight loss.
Metabolism support:
In animal studies, it was found that citral has the ability to lower fat accumulation and improve markers of lipid metabolism. There is not enough human clinical evidence on water lemon grass tea for weight loss but mechanistic evidence from animal and in-vitro studies indicates there is a real metabolic benefit when regularly consumed.
Blood sugar stabilization:
The chlorogenic acid in lemongrass prevents the increase in blood sugar levels after eating as well as the subsequent fat storage, which occurs due to the release of insulin. One of the most critical physiological conditions for maintaining a full and healthy appetite and decreasing cravings, especially for sweet and high-calorie foods, is stability in blood sugar.
Calorie replacement:
The easiest to follow water lemon grass tea for weight loss method is the replacement one since it is just replacing sugary chai or packaged juice or commercial beverages with lemongrass tea is a very effective way of reducing calorie intake without a need to exercise any self-discipline.
- Antimicrobial and Immune-Boosting Properties
A one of the most scientific amazing features of lemongrass tea is its powerful antimicrobial property which is very crucial in the country of India as food and waterborne disease infection is a very serious health problem. Citral and geraniol have shown inhibitory activity against a range of bacterial and fungal pathogens in vitro, such as Escherichia coli, Staphylococcus aureus, Salmonella typhi and the fungal pathogen Candida albicans. Microbios research published that citral could kill 22 out of 36 tested bacteria strains including multiple drug-resistant bacteria.
The lemon grass immune boosting properties are also attributable to its immune modulation action, as flavonoids in lemongrass increase the activity of the innate immune system's components, such as macrophages and natural killer cells. It's a traditional practice and has a very real evidence-based rationale when it comes to drinking lemongrass tea during monsoon season, when the risk of waterborne pathogens is high.
- Regulates Blood Sugar and Supports Metabolic Health
Lemongrass tea has several clinically relevant health benefits that benefit a large segment of India's population suffering from diabetes and pre-diabetes, particularly in terms of blood sugar management. The administration of lemongrass extract in randomly selected subjects resulted in a significant decrease in fasting blood glucose, which was thought to be due to the alpha-glucosidase inhibitory activity of chlorogenic acid and the insulin stimulatory activity of isoorientin in cells. These mechanisms provide a rationale for using lemon grass tea as a glycaemic buffering strategy before or with meals, especially carbohydrate-rich Indian meals, and may constitute a simple, cost-effective everyday practice towards metabolic wellness.
- Supports Heart Health and Healthy Cholesterol Levels
The last but by no means least important of all the benefits of lemongrass tea is cardiovascular protection. The C-glycosyl flavones found in greater concentration in lemongrass, orientin and isoorientin have been shown to exert cholesterol-lowering effects during clinical trials, where they lowered LDL and total cholesterol levels with a slight increase in HDL in participants with mild hyperlipidaemia. In a 90-day human study published in the Journal of the American College of Nutrition, scientists reported that essential oil supplementation with lemon grass resulted in significant decreases in cholesterol levels when compared to the placebo group. The potassium is helpful in regulating blood pressure and citral acts as an anti-platelet agent to prevent arterial clots. The health benefits of Lemongrass tea for cardiovascular health are some of the most comprehensive of all the popular herbal teas.
Water Lemon Grass Tea for Weight Loss: How to Prepare It Correctly
The preparation of lemon grass tea for weight loss is important to maximize the benefits of water lemon grass tea benefits:
- Bring 2 cups of water to a boil.
- Bruised 2-3 stalks of fresh lemongrass or 1 tablespoon of dried lemongrass
- Steep on low heat for 5–10 minutes (longer steeping extracts more chlorogenic acid and flavonoids)
- Add fresh ginger slices to further boost digestive and metabolic effects
- Strain and serve with a squeeze of lemon and a little honey (if you wish).
- For optimum weight loss lemon grass tea results, drink without any sugar added.
- Consume between 2-3 cups per day (usually taken 3 times) before breakfast, mid afternoon and possibly in the evening.
Lemon Grass Tea Side Effects: -
It is crucial that all lemon grass tea side effects are reported responsibly in order to enable safe consumption. Lemongrass tea is very safe when used in normal dosages, but some lemon grass tea side effects warrant attention:
Pregnancy and lactation:
This is the most definite of all the lemon grass tea side effects warnings. Lemongrass has a reputed stimulating action on menstruation and has been shown to be uterotonic at high doses. Lemon grass in its medicinal strength is not recommended when pregnant. The culinary use of food in the human context is usually safe, but potent therapeutic infusions are to be avoided. Women who are breastfeeding should check with their healthcare provider before using regularly for therapy.
Excessive diuresis at high doses:
Prolonged use of lemon grass tea (more than 4–5 strong cups a day) can lead to its side effects and can deplete potassium or other electrolytes in the body, which can pose problems. This risk is very low if you drink 2–3 cups a day.
Low blood pressure:
In people who are already taking anti-hypertensive medicine, the effect of lemongrass on blood pressure could be added to the effects of their medicine and cause blood pressure to be too low. This is one of the side effects of lemon grass tea that is important to the patient who takes medicines and has to be monitored regularly by a doctor.
Conclusion
Lemongrass tea benefits are wide with strong traditional and new clinical research foundations and quite accessible as it only takes a few stalks of a plant that proliferates throughout India, which is steeped in boiling water for 10 minutes. From its calming effects for an after-work or wind-down tea, to the weight loss properties of a daily cup of lemon grass tea before meals, to a caffeine-free alternative to black chai, the rewards of drinking a cup of lemon grass tea daily are undeniable.
Lemon grass is one of the most multi-functional and all-around beneficial plants of the Indian herbal practice, all the way from the kitchen garden to the tea cup to the medicine cabinet. However, it is advisable to be mindful of the lemon grass tea side effects at higher dosages or when pregnant, but if taken in a normal dosage, daily consumption of lemon grass tea is regarded as one of the safest, effective and under-used herbal drinks in 2026.

Frequently Asked Questions (FAQs)
Q1. How many cups of lemongrass tea should I drink per day?
Most healthy adults can safely consume 2–3 cups of lemongrass tea per day to experience the maximum potential health benefits of lemongrass tea without the electrolyte-lowering side effects or diuretics that can be found with excessive consumption. The most recommended time for drinking is one cup in the morning, one in the afternoon and a relaxing cup in the evening before bedtime. Avoid using more than 4-5 cups per day regularly.
Q2. Can lemongrass tea help with weight loss?
Yes — but there is some nuance. Water lemon grass tea for weight loss mechanisms are genuine yet minor in themselves. The diuretic property helps to decrease water retention, chlorogenic acid helps to slow blood sugar and water displacement of calorie rich fluids with calorie free lemongrass tea decreases caloric consumption. But the advantages of lemon grass tea weight loss is best realized when used as a component of a healthy eating and exercise plan rather than a weight loss remedy in itself. Most will see significant results from consistent daily application for 8-12 weeks along with dietary awareness.
Q3. What are the main lemon grass tea side effects to watch for?
The key points that should be kept in mind about side effects of the lemon grass tea are: pregnant women should avoid using the tea because of its uterotonic effect, excessive diuretic use at very high consumption level of the tea (2–3 cups per day), it might affect the antihypertensive and antidiabetic drugs, and rare allergic reaction of the tea in people who are sensitive to grass pollen. The lemon grass tea side effects profile is very mild, and mainly theoretical, for healthy, non-pregnant adults who are not taking any significant medication at the recommended dosage of 2–3 cups per day.
Q4. Can I drink lemongrass tea on an empty stomach?
Yes — drinking lemongrass tea on an empty stomach is one of the best ways to obtain the metabolic and digestive property of drinking lemon grass tea. These compounds which stimulate digestive enzymes and chlorogenic acid are most effective when the digestive tract is not full of food. Those who are sensitive to the acidity of the herbal teas and experience an upset tummy when consumed on an empty stomach can take a little honey to help neutralise the acidity and still reap the benefits of the herbs.
Q5. Is fresh lemongrass better than dried for tea?
Both provide the main health properties of lemongrass tea, but having some variations. Fresh lemongrass has higher concentrations of citral and volatile terpenoids that volatilize during dry harvest, which leaves fresh lemongrass with a higher microbial, anxiolytic and aromatic activity than dry lemongrass. Dried lemongrass is more potent per gram, more shelf-stable, and is easier to use all year long. High-quality dried lemongrass is also a completely adequate replacement for fresh for daily use to treat, especially when steeped for a full 8–10 minutes to make up for any potential loss of volatile compound.
