Lemongrass essential oil, derived from Cymbopogon citratus or Cymbopogon flexuosus, offers at least 30 documented benefits spanning skin health, hair care, digestive support, immune function, and emotional well-being. Its primary bioactive compound, citral, drives most of its antimicrobial, anti-inflammatory, and antioxidant effects.
Few natural ingredients carry as many well-researched applications as lemongrass essential oil. Distilled from the stalks and leaves of a tall, fast-growing tropical grass native to South and Southeast Asia, this pale-yellow oil has been used in Ayurvedic and traditional Asian medicine for centuries. Today, modern research is confirming what traditional practitioners long understood: lemongrass essential oil is one of the most versatile therapeutic oils available.
The oil’s primary bioactive compound is citral — a blend of the aldehydes geranial and neral that constitutes 70–80% of the oil. Citral is responsible for lemongrass essential oil’s characteristic bright, lemony aroma and the majority of its documented therapeutic effects. Supporting compounds including geraniol, citronellol, limonene, and myrcene contribute additional antimicrobial, anti-inflammatory, and antioxidant activity.
A 2024 scoping review published in PMC confirmed broad-spectrum antimicrobial activity — including against drug-resistant bacterial strains — strong antifungal action, and anti-inflammatory effects through reduction of proinflammatory cytokines. A separate 2022 study concluded that lemongrass “can be considered a promising natural source of readily available, low-cost extracts rich in antioxidant, skincare, and antimicrobial compounds.” The evidence base continues to grow.
This article covers all 30 documented benefits of lemongrass essential oil, organized by category, with the relevant research behind each one. One important note before diving in: lemongrass essential oil should always be diluted in a carrier oil before any skin application. Its high citral content makes it potent — effective, but requiring careful use. Always perform a patch test before topical use, and consult a healthcare professional before internal use or if you take prescription medications.
Benefits for Skin
1. Tones and Tightens Pores
Lemongrass essential oil functions as a natural astringent, temporarily tightening pores and creating a more refined skin texture. Citral’s astringent properties remove accumulated sebum, environmental debris, and surface bacteria — particularly beneficial for oily and combination skin types. A 2017 study published in Biochimie Open tested lemongrass essential oil on pre-inflamed human dermal fibroblasts and concluded it is “a good therapeutic candidate for treating inflammatory conditions of the skin.” Added to a diluted facial oil or cleanser, it sterilizes pores while acting as a natural toner that strengthens skin tissue without synthetic additives.
2. Supports Acne-Prone Skin
Lemongrass essential oil demonstrates antibacterial activity against Cutibacterium acnes, the primary bacteria responsible for acne. This makes it a meaningful natural addition to acne-focused skincare routines. A 2024 scoping review confirmed lemongrass essential oil’s broad-spectrum antimicrobial activity against drug-resistant bacterial strains and biofilms — the same mechanism that makes it effective at reducing acne-causing bacteria on skin surfaces. What distinguishes it from other antimicrobial oils is the combination of antibacterial action with pore-tightening astringency, addressing both the bacterial cause of breakouts and the enlarged pores that trap debris.
3. Delivers Antioxidant Skin Protection
Free radicals generated by UV exposure and environmental pollution are primary drivers of skin aging, hyperpigmentation, and barrier damage. Lemongrass essential oil contains well-documented antioxidant compounds — citral among them — that scavenge these free radicals. Research published in 2022 confirmed lemongrass can provide “protective measures against various oxidative processes.” Incorporated into an evening facial oil blend, lemongrass essential oil contributes antioxidant protection during the skin’s overnight repair cycle. While it is best understood as a complementary antioxidant rather than a substitute for dedicated actives like Vitamin C, its contribution to overall skin defense is meaningful.
4. Soothes Inflammatory Skin Conditions
The 2024 study confirming lemongrass essential oil’s anti-inflammatory mechanism — specifically the reduction of proinflammatory cytokines TNF-alpha and IL-6 — has direct implications for inflammatory skin conditions such as rosacea, dermatitis, and general skin irritation. When diluted appropriately and applied to affected areas, lemongrass essential oil can reduce redness and calm irritation by targeting the cytokine-driven inflammatory cascades that produce visible symptoms. People with particularly sensitive skin or diagnosed conditions like rosacea should perform a careful patch test, given citral’s sensitization potential at higher concentrations.
5. Helps Treat Ingrown Hairs
Lemongrass essential oil’s antiseptic and astringent properties make it a useful post-shave or post-wax treatment for ingrown hairs. By unclogging pores and removing the debris and excess sebum that trap hairs beneath the skin surface, it reduces the conditions that lead to ingrowth. Its antimicrobial action simultaneously helps prevent the inflammation and bacterial infection that can accompany ingrown hairs, reducing the itching and redness associated with them. Applied diluted to a carrier oil and massaged gently into the affected area after hair removal, lemongrass essential oil soothes and protects skin while reducing ingrown hair frequency over time.
6. Acts as a Natural Skin Cleanser
A 2022 research review concluded that lemongrass essential oil is suitable as a natural replacement for synthetic antimicrobial compounds in the cosmeceutical industry. Its antiseptic properties make it an effective cleanser for all skin types, removing surface bacteria without disrupting the skin’s overall microbiome. It can be added to homemade face washes, body scrubs, or diluted into existing cleansers to boost their antimicrobial performance naturally. The oil’s light consistency and bright citrus scent also make it a pleasant base ingredient for DIY body care formulations, serving both aesthetic and functional purposes in any cleansing routine.
Benefits for Hair and Scalp
7. Reduces Dandruff
Among all lemongrass essential oil applications, its anti-dandruff effect carries some of the strongest clinical evidence. A 2015 study found that a hair tonic containing lemongrass essential oil applied to the scalp significantly reduced dandruff scores after just one and two weeks of use compared to a placebo. The mechanism is citral’s disruption of fungal cell membranes — specifically targeting Malassezia, the yeast primarily responsible for dandruff formation. For anyone seeking a natural alternative to medicated anti-dandruff shampoos, diluted lemongrass essential oil massaged into the scalp before washing is a well-supported, evidence-backed option.
8. Strengthens Hair Follicles and Supports Scalp Health
Lemongrass essential oil supports hair follicle health through multiple pathways: reducing scalp inflammation, regulating sebum production, deep-cleansing the follicle environment, and exerting antimicrobial action against the bacteria and fungi that disrupt the scalp biome. Research confirms the oil can strengthen hair follicles, helping address itchy, irritated scalps. Critically, lemongrass essential oil works as a scalp health ingredient rather than a direct hair growth stimulant — it does not inhibit 5-alpha reductase or directly increase blood flow the way rosemary or peppermint oil do. However, by improving scalp conditions, it removes barriers to healthy hair cycling.
9. Controls Scalp Inflammation
Chronic scalp inflammation is an underappreciated driver of hair thinning and poor hair quality. It disrupts the hair growth cycle, impairs follicle function, and creates the persistently itchy, sensitive scalp environment that worsens dandruff. Lemongrass essential oil’s confirmed anti-inflammatory action — through reduction of proinflammatory cytokines — directly addresses this scalp environment issue. Regular use of diluted lemongrass essential oil as a pre-shampoo scalp treatment can reduce the inflammatory conditions that suppress normal hair cycling, creating a healthier foundation for hair growth over time, particularly for people whose hair concerns are partly driven by scalp inflammation.
10. Enhances Hair Shine and Texture
Lemongrass essential oil helps regulate the scalp’s natural oil production, ensuring hair remains hydrated without becoming greasy. This sebum balance is one of the primary factors in maintaining a natural, healthy shine. Its astringent properties tone and purify the scalp, creating the ideal environment for lustrous hair. Regular diluted use can strengthen hair strands over time, improving overall hair texture and reducing split end breakage — a common cause of dull, lackluster hair. Unlike silicone-based commercial products that coat hair strands superficially, lemongrass essential oil supports shine from the scalp outward through improved follicle and strand health.
11. Eliminates Scalp and Hair Odor
Persistent scalp odor often stems from excess product buildup, bacterial activity, or sebum oxidation — all areas where lemongrass essential oil’s antimicrobial properties are directly relevant. Its broad-spectrum antibacterial activity addresses odor-causing bacteria at the scalp surface, while its astringent properties help remove product residue and sebum buildup between washes. The oil’s bright, clean citrus fragrance also provides a naturally pleasant scent without synthetic perfumes. For anyone who experiences persistent scalp odor that regular shampooing does not fully resolve, a pre-wash scalp treatment using diluted lemongrass essential oil can address the root causes rather than simply masking them.
12. Acts as a Natural Lice Repellent
Lemongrass essential oil’s high citral and geraniol content gives it documented insect-repellent properties that extend to head lice — a common concern among school-age children. Adding a few drops of diluted lemongrass oil to shampoos, conditioners, or hair sprays can help create a natural barrier against lice while simultaneously supporting scalp cleanliness. Lemongrass essential oil offers a gentler, fragrance-pleasant alternative to synthetic lice-prevention products for families looking to reduce chemical exposure. Its dual action as both a scalp health ingredient and a natural repellent makes it a particularly practical addition to children’s hair care routines.
Benefits for Mental and Emotional Well-being
13. Reduces Stress and Anxiety
Lemongrass essential oil has clinical support for its anxiolytic effects — one of the more substantiated aromatherapy applications in the research literature. A study published in the Journal of Alternative and Complementary Medicine found that subjects exposed to an anxiety-inducing situation who inhaled lemongrass oil experienced a significant decrease in anxiety and subjective tension immediately after treatment, compared to control groups. The proposed mechanism involves citral’s interaction with GABA receptors in the central nervous system — the same receptors targeted by many anti-anxiety medications, though through a considerably gentler pathway. Diffusing lemongrass essential oil in a workspace or living area is a practical application of this evidence.
14. Provides Headache Relief
Lemongrass essential oil is frequently recommended for tension headaches and stress-related head pain. Its calming and anti-inflammatory properties — driven by citral — help relieve the pressure, tension, and vascular constriction that contribute to headache onset. When diluted and massaged into the temples or the back of the neck, lemongrass essential oil delivers localized anti-inflammatory action while the oil’s bright citrus aroma simultaneously promotes relaxation and stress reduction. Scalp massage using diluted lemongrass also improves blood circulation to the head and provides physical tension relief — addressing both the mechanical and the neurological contributors to tension headaches.
15. Supports Emotional Balance and Mood
Beyond its documented anxiolytic effect, lemongrass essential oil has a broader reputation in aromatherapy practice for its uplifting and balancing qualities. The oil is described by aromatherapy educators as stimulating, relaxing, soothing, and balancing — a combination that makes it useful for mood support across a range of emotional states. Its bright, fresh citrus scent provides an immediate sensory lift without the sharp edge of pure citrus oils. For use during periods of mental fatigue or emotional overload, diffusing lemongrass essential oil or incorporating it into a personal inhaler is a straightforward, evidence-adjacent strategy for restoring a sense of clarity and calm.
Benefits for Digestive and Internal Health
16. Protects Against Gastric Damage
Lemongrass essential oil has a documented history as a treatment for stomach distress across multiple traditional medicine systems. A 2012 research study demonstrated that lemongrass essential oil (Cymbopogon citratus) protected animal subjects from gastric damage caused by both ethanol and aspirin. The study concluded that lemongrass oil “might serve as a lead compound for future development of novel therapies that combat NSAID-associated gastropathy.” A separate study showed it promotes gastric healing activity. While further human trials are needed, this line of research suggests lemongrass essential oil may have genuine protective value for stomach lining integrity when used carefully and appropriately.
17. Eases Digestive Discomfort and Gas
Lemongrass essential oil helps relieve the discomfort associated with excess gas in the stomach and bowels — a traditional use now supported by modern understanding of its antispasmodic properties. Its calming effect on smooth muscle in the digestive tract can reduce cramping and bloating associated with gas buildup. Research also supports its ability to slow diarrhea: a 2006 study showed lemongrass oil reduced fecal output in mice with castor oil-induced diarrhea. Additionally, lemongrass essential oil has been shown to promote healthy gut microbiota, contributing to the broader gut health that underlies comfortable and efficient digestion.
18. Supports Liver and Kidney Detoxification
Lemongrass oil has been used as a detoxifier across numerous traditional medicine systems, including in Brazil, the Amazon, and across Southeast Asia. Research supports its ability to help detoxify the digestive tract, liver, kidneys, bladder, and pancreas through its natural diuretic action — increasing urine output and helping the body flush accumulated toxins more efficiently. A 2022 study published in PMC reviewed its detoxifying potential, and the evidence supports regular moderate use for supporting the body’s natural elimination pathways. Adding a drop to herbal tea or warm water is one of the most common internal applications cited in traditional use.
19. Relieves Menstrual Cramps
Drinking lemongrass tea is a well-established traditional remedy for menstrual discomfort, and modern research offers supporting evidence. Lemongrass essential oil contains antispasmodic compounds that help relax uterine smooth muscle, reducing the cramping intensity associated with menstruation. It has also been shown to help with the associated symptoms of nausea and irritability that frequently accompany painful periods. One to two cups of lemongrass tea per day during menstruation is the most commonly referenced approach. Lemongrass essential oil may also be diluted in a carrier oil and massaged onto the lower abdomen to provide topical antispasmodic and anti-inflammatory relief.
20. Acts as a Natural Diuretic and Detoxifier
Beyond its targeted support for liver and kidney function, lemongrass essential oil’s broader diuretic properties make it useful for reducing water retention and supporting overall fluid balance in the body. By increasing urinary output, it helps the body eliminate not only toxins but also excess sodium that contributes to bloating. Research published in PubMed confirms that lemongrass can help flush harmful toxins from the body through this diuretic mechanism. This action, combined with its antimicrobial properties in the urinary tract, gives lemongrass essential oil a comprehensive cleansing role that extends well beyond simple surface-level applications.
Benefits for Physical Health
21. Relieves Muscle Pain and Cramps
Lemongrass essential oil is well-established as a topical muscle relaxant. Research confirms its ability to relieve muscle aches, cramps, and spasms, and it may also improve local circulation when massaged into the affected area. Its anti-inflammatory compounds address the underlying inflammatory component of muscle soreness, while its antispasmodic properties directly relax contracted muscle fibers. A lemongrass essential oil foot bath — approximately 10 drops in warm water — is a practical application for end-of-day foot and lower leg muscle fatigue. Diluted lemongrass oil can also be blended with a carrier oil and applied as a post-exercise massage oil for broader muscle recovery support.
22. Reduces Inflammation Throughout the Body
Inflammation underlies the majority of chronic diseases, from cardiovascular conditions to autoimmune disorders and metabolic syndrome. Lemongrass essential oil demonstrates anti-inflammatory effects both internally and externally, with multiple studies confirming its ability to reduce proinflammatory cytokines and inhibit inflammatory pathways. A 2022 study exploring the anti-hypertensive potential of lemongrass compiled substantial evidence of the oil’s systemic anti-inflammatory effects. Research published in 2017 confirmed its specific relevance to inflammatory skin conditions at the cellular level. Whether diffused, applied topically in diluted form, or consumed as lemongrass tea, its anti-inflammatory action operates through well-documented biochemical mechanisms.
23. Eases Rheumatoid Arthritis Symptoms
The anti-inflammatory properties of lemongrass essential oil have been specifically evaluated in the context of rheumatoid arthritis. A 2017 study examined the effects of topically applied lemongrass essential oil on 30 participants aged 35 to 70 with confirmed rheumatoid arthritis. Participants applied 3 milligrams of lemongrass essential oil over 30 days and reported a measurable reduction in pain over the treatment period. While the study involved a relatively small sample and further large-scale clinical trials are needed, the findings align with the broader anti-inflammatory research base for lemongrass oil and offer encouraging preliminary evidence for joint pain management.
24. Reduces Fever
Lemongrass essential oil has a history of use as a natural fever reducer in traditional medicine across Africa, South America, and Southeast Asia. Its cooling properties produce a perceptible reduction in body temperature when applied topically or inhaled, and it contains substances documented by WebMD as “believed to reduce a fever and also relieve pain and swelling.” In the Amazon, lemongrass is traditionally prepared as a sedative tea with fever-reducing properties. In Guatemala, the Carib people use lemongrass leaf tea specifically for fever management. These traditional uses are consistent with the oil’s documented anti-inflammatory and antipyretic compound profile.
25. Supports Immune Function
Lemongrass essential oil supports immune function through several converging pathways. In vitro research has shown that lemongrass oil can reduce pro-inflammatory cytokines in the body — cytokines that, when chronically elevated, contribute to immune dysregulation and illness susceptibility. Animal studies have also found that lemongrass oil supplementation “improved the immune responses and disease resistance” of subjects. Its broad antimicrobial properties — effective against bacteria, fungi, and some viruses — also reduce the pathogen load the immune system must manage. Used preventively during periods of increased illness risk, lemongrass essential oil offers meaningful support to the body’s natural defense mechanisms.
26. Fights Bacterial and Viral Infections
Lemongrass essential oil demonstrates potent antibacterial activity that extends to airborne pathogens. A 2011 scientific article described lemongrass oil as “an effective panacea against bacteria, flu and colds” when used as a vaporizer. Research testing lemongrass oil vapors in an enclosed environment found a 38% reduction in bacteria growth on seeded plates after 20 hours. In an office setting, 89% of airborne bacteria was eliminated within 15 hours. The study concluded that lemongrass essential oil can function as a method of air disinfection, inhibiting both antibiotic-sensitive and antibiotic-resistant bacterial strains — making it particularly relevant as antibiotic resistance becomes a growing public health concern.
27. May Help Lower Cholesterol
A research study published in the journal Food and Chemical Toxicology examined the effects of oral lemongrass essential oil supplementation on cholesterol levels over 21 days in animal subjects with elevated cholesterol. Animals given the highest dose of lemongrass oil (100 mg/kg) showed measurable reductions in blood cholesterol levels. The study concluded that the “findings verified the safety of lemongrass intake at doses used in folk medicine and indicated the beneficial effect of reducing the blood cholesterol level.” While human clinical trials are still needed to confirm these effects in people, the preliminary findings provide a compelling basis for continued investigation into lemongrass oil’s cardiovascular benefits.
28. Supports Lymphatic and Edema Management
According to the New York Institute of Aromatic Studies, lemongrass essential oil “acts particularly on the connective tissue, where structural and immune functions meet. Lemongrass acts on the lymphatic capillaries and vessels draining away from the skin, so it is useful in edema and lymphatic congestion.” This lymphatic action complements lemongrass essential oil’s broader detoxifying and diuretic properties — together creating a meaningful tool for reducing localized swelling and supporting the lymphatic system’s waste-removal function. Topical application of diluted lemongrass essential oil through massage over areas of congestion is the most direct method of activating this lymphatic drainage response.
29. Supports Blood Sugar Regulation
Citral — lemongrass essential oil’s primary compound — has documented hypoglycemic effects in laboratory studies, suggesting potential support for blood sugar regulation. This activity is significant enough that healthcare providers advise people on diabetes medications to be aware of potential interactions before incorporating lemongrass oil into regular use. While this means caution is warranted for people on prescribed blood sugar management medications, it also points to lemongrass essential oil’s potential relevance as a complementary tool in metabolic health support. Further controlled clinical trials are needed to quantify the precise effect in humans, but the underlying biochemical mechanism is well-established in the existing research.
Benefits for Home and Lifestyle
30. Natural Deodorizer, Cleaner, and Food Preservative
Lemongrass essential oil has a dual-purpose role in the home: as a natural deodorizer and as an antimicrobial surface cleaner. Research confirms it sanitizes surfaces effectively while its bright citrus scent naturally freshens air without synthetic fragrance compounds. It can be added to water for use as a room mist, incorporated into DIY cleaning sprays, or diffused to eliminate airborne bacteria. Beyond home cleaning, lemongrass essential oil has a long history as a natural food preservative — its inherent antimicrobial properties inhibit the bacterial and fungal growth that causes spoilage. The FDA recognizes pure lemongrass oil as safe for consumption, supporting its use in culinary and food preservation applications.
Using Lemongrass Essential Oil Safely and Effectively
Understanding the full range of lemongrass essential oil’s benefits is the first step; using it correctly is equally important. The oil can be applied in three primary ways.
Aromatically, it can be diffused in a room using an oil diffuser or vaporizer. Thirty- to sixty-minute sessions in a well-ventilated space are recommended rather than continuous all-day diffusion. Lemongrass essential oil blends particularly well with lavender, bergamot, cedarwood, geranium, and rosemary for customized aromatherapy blends.
Topically, it must always be diluted with a carrier oil such as jojoba, coconut, or sweet almond oil before skin contact. A dilution of 1% (approximately 2 drops per 10ml of carrier) is appropriate for face applications; 2–3% is suitable for body and scalp use. Always perform a patch test on the inner forearm and wait 24 hours before broader application. Avoid applying near the eyes, ears, or mucous membranes.
Internally, lemongrass is most safely consumed as a tea — pour two cups of boiling water over 10 lemongrass leaves and steep. The FDA recognizes pure therapeutic-grade lemongrass essential oil as safe for consumption, but internal use of the concentrated oil should only be undertaken with guidance from a qualified healthcare professional.
Lemongrass essential oil should not be used during pregnancy due to its ability to stimulate uterine contractions, and it is not recommended for use on children under age 10 without professional guidance. Store the oil in a dark glass bottle in a cool, dry location to prevent citral oxidation, which degrades potency and increases skin sensitization risk.
The Case for Lemongrass Essential Oil
Few natural substances offer the breadth of documented, research-supported benefits that lemongrass essential oil delivers. From antimicrobial surface cleaning to rheumatoid arthritis symptom management; from dandruff elimination to immune system support; from tension headache relief to potential cholesterol reduction — the range reflects the remarkable therapeutic profile of a single plant-derived compound.
The most important takeaway is that the evidence is substantive, not anecdotal. The benefits described in this article are supported by peer-reviewed studies, clinical trials, and systematic reviews published in credible scientific journals. Where the evidence is preliminary — such as cholesterol reduction and blood sugar regulation — the underlying biochemical mechanisms are sound, and the research base is actively developing.
Start with one or two targeted applications based on your most pressing needs, use the oil correctly and at the right dilution, and build from there. Lemongrass essential oil rewards consistent, informed use — and the return on that investment, across multiple dimensions of health and well-being, is well worth the effort.
As with any natural therapeutic product, consult your healthcare provider before incorporating lemongrass essential oil into your routine if you are pregnant, taking prescription medications, or managing a chronic health condition.
