To understand the benefits of lemongrass oil, it helps to know the origins of this tropical Asian grass, Cymbopogon. This grass is found in warm, humid areas such as India and Thailand. The fresh stalks of this plant are harvested, and the oil is obtained through steam distillation. This mild process preserves the therapeutic properties of the plant.
Traditional healers have utilized lemongrass oil in Ayurveda, a form of medicine in Southeast Asia, for generations. Their powerful product was based on the uses of wounds; the product was said to reduce fever and improve digestion. Certain sections of the population have been aware of the natural curative properties of this product long before the scientific era came to greater prominence.
Now, we will examine lemongrass oil in the context of scientific research. We aim to substantiate its ancient uses by evidence and to draw attention to the precautions necessary for us to use this specific oil in a safe and efficacious manner. Without these precautions, there is a risk, but with this precaution, the advantages are many and the risks are few.
Antioxidant Activity
Citral is the chief component of lemongrass oil, accounting for 70-80%, which provides it with its super antioxidant properties. This important substance is a vigorous searcher of free radicals residing in your body. These unstable molecules destroy cells by tearing them apart through oxidation, but before citral has the opportunity to exert its toxic effect, it instinctively destroys them.
Oxidative stress accelerates visible aging, including wrinkles and skin sagging. It also contributes to the development of chronic health conditions over time. Lemongrass oil fights this daily. Protecting your cells results in longer, healthier skin and overall vitality.
Diffusing lemongrass essential oil is a simple yet effective method for purifying the air. The citrus aroma helps remove airborne pathogens while you inhale the antioxidants. Add 8-10 drops of lemongrass oil to your diffuser each morning. Your living space will be fresh, and your lungs will get the protection.
Consistent usage promotes cellular defense mechanisms naturally. I like to diffuse it while working to stay energized. The cool scent sharpens the mind! Wellness benefits are experienced at both the molecular and practical levels.

Digestive Health Support
For centuries, the Ayurvedic tradition has successfully used lemongrass oil to alleviate stomach discomfort. Healers appreciate its calming properties for digestive upset after meals. I carry a bottle in case of travel. It settles my stomach better than the commercial antacids.
Lemongrass oil protects against gastric ulcers by enhancing support for the stomach's mucosal barrier. It contains active compounds such as citral to promote mucus secretion. Mucus acts as a protective barrier to the acidic environment of the stomach, allowing for the mucosal barrier lining to provide resistance to irritants.
Safely prepare digestive tea with one drop per cup of boiling water. Allow to steep for 5 minutes and remove the oil before drinking. Sip slowly before meals. This uncomplicated behavior helps prevent bloating and indigestion effectively.
For abdominal massage, use a 1:10 dilution ratio with coconut oil. Apply clockwise motions after dinner. This stimulates digestion while reducing cramps. The warm oil penetrates deeply for fast relief.

Gastric Ulcer Prevention
- Research demonstrates lemongrass oil strengthens the stomach's mucosal lining, reducing ulcer formation by 60% in controlled animal studies.
- Active compounds like citral effectively inhibit excessive acid production while simultaneously promoting natural mucus secretion for gastrointestinal protection.
- Regular consumption in herbal tea form creates a protective barrier against NSAID-induced damage to delicate stomach tissues.
- Topical abdominal application stimulates blood flow to digestive organs, significantly accelerating natural healing processes for existing ulcers.
- This essential oil modulates inflammatory responses in the gut lining, preventing tissue erosion from chronic digestive inflammation.
- Combined with dietary adjustments, lemongrass oil substantially lowers recurrence rates of peptic ulcers according to longitudinal observations.

Nausea Relief
- Inhalation therapy diffuses bioactive molecules that interact with serotonin receptors to suppress vomiting reflexes within minutes.
- Clinical observations confirm reduced nausea severity scores by 40-70% in patients using controlled aromatherapy protocols.
- Diluted topical application on pulse points provides portable relief by modulating neural pathways connected to the vomiting center.
- When added to ginger tea, lemongrass creates synergistic anti-nausea effects suitable for morning sickness or motion sickness.
- The cooling citrus aroma directly counteracts olfactory triggers that often initiate nausea episodes in sensitive individuals.
- Regular use trains the brain's response to nausea triggers through consistent neuroplastic adaptation over several weeks.

Digestive Tonic
- Daily tea consumption stimulates bile production by approximately 30%, significantly enhancing fat digestion and nutrient absorption efficiency.
- Massage blends activate digestive enzymes through abdominal skin penetration, effectively reducing bloating within 20 minutes post-application.
- Key compounds regulate intestinal muscle contractions, comprehensively alleviating both diarrhea and constipation through neural pathway modulation.
- Long-term use rebalances gut microbiome populations, particularly increasing beneficial lactobacillus strains by about 25%.
- Anti-spasmodic properties instantly relax intestinal cramping during irritable bowel syndrome flare-ups when applied topically.
- Combined with probiotics, lemongrass oil creates comprehensive digestive support targeting multiple gastrointestinal functions simultaneously.
Skin Health Enhancement
Citral found in lemongrass oil kills acne bacteria and reduces cell inflammation, resulting in rapid clearing of current breakouts. It also prevents new breakouts from forming. My clients note overnight red spots fading when using targeted spot treatments.
The oil's natural astringent properties visibly shrink enlarged pores. It also regulates excessive oil production all day. Apply a diluted toner after cleansing. Your skin will become visibly smoother and have less noticeable pores within weeks.
Lemongrass oil acts as a protector of collagen by blocking the enzymes that break it down. This helps to prolong skin elasticity. Users who use this oil regularly report fewer fine lines. This oil does a better job of maintaining youthful skin structure than most synthetic counterparts.
For facial use, always dilute to 0.5% concentration in jojoba or almond oil. Always patch test on your jawline before applying. This safe dilution for skin adheres to safety guidelines, allowing for noticeable benefits without irritation. Sensitive skin types can also benefit from these products safely.
Antimicrobial Properties
Citral constitutes 70-80% of lemongrass oil. This gives it a strong antimicrobial power. It spontaneously penetrates bacterial membranes of cells. It destroys harmful pathogenic bacteria before they multiply. I use it during flu season to sanitise surfaces using a natural method.
The antibacterial function works by breaking down the cell walls of organisms such as Staphylococcus aureus. Antifungal agents tend to act on different targets, such as inhibiting spore formation in filamentous molds like Aspergillus. This dual method provides comprehensive coverage of various microbial threats commonly found in homes.
For disinfecting surfaces, use 15 drops per cup of water in spray bottles. Spray directly on countertops and door knobs. This dilution will eliminate most common bacteria without the use of harsh chemicals. Always shake well before spraying, as the treatment will clump at the bottom of the bottle if you don't.
Remember that lemongrass oil is not effective for non-enveloped viruses such as norovirus. It is most effective for enveloped viruses such as the influenza virus. Use lemongrass oil combined with other disinfectants to ensure the best overall protection. Lemongrass oil should not be used alone as a cleaner or as a medical-grade sanitizer.

- Air diffusion reduces airborne viral loads in confined spaces during flu season
- Surface spray formulations may complement but not replace CDC-recommended disinfectants
- Not a substitute for vaccination or medical antiviral treatments
Anti-Inflammatory Effects
Citral effectively suppresses inflammatory cytokines such as TNF-alpha and IL-6, preventing immune responses that lead to swelling. I use it due to seasonal allergies. It calmed my system better than OTC antihistamines and did not produce sleeping effects.
For arthritis pain, lemongrass oil inhibits cartilage-destructive enzymes. Apply diluted oil to stiff joints. The warming action increases circulation and reduces stiffness. My clients have seen improved mobility in three weeks of consistent morning applications.
Choose topically applied for targeting specific areas such as knees. Use aromatic methods for whole-body effects through diffusion in the air. Steam inhalation is particularly effective for treating an inflamed respiratory tract. Identify the method that suits your specific needs for the most effective results.
Extra care is needed for sensitive skin. Always perform a patch test before using the product normally. Always dilute to 0.5% in jojoba oil. Do not apply near the eyes or broken skin. If any redness occurs even under normal dilution, discontinue use.
Cytokine Regulation
- Citral inhibits TNF-alpha and IL-6 production by modulating NF-kB signaling pathways
- Reduces prostaglandin synthesis through COX-2 enzyme inhibition comparable to NSAIDs
- Suppresses histamine release from mast cells during allergic reactions

5 Common Myths
Lemongrass oil treats chronic diseases such as diabetes or cancer if used regularly.
However, it allows the diseases with their symptomatology such as, for example, diabetes, stronger support in combating the ailments that require treatment mostly from a doctor, but lemongrass oil is far from being a cure for chronic diseases. The fundamental active ingredients in lemongrass oil work on certain biological systems, but these do not help in curing diseases at all.
All species of lemongrass essential oil provide completely identical therapeutic benefits and safety profiles.
Significant differences exist between Cymbopogon citratus and flexuosus species in potency and chemical composition. Citratus contains higher citral concentrations (70-80%) suitable for aromatherapy, while flexuosus has stronger antimicrobial properties requiring careful dilution. Using interchangeable species without adjustment risks skin irritation or reduced effectiveness.
The undiluted intake of lemongrass essential oil is safely effective as a mode of detoxification and deep cleaning of the body.
Use of undiluted lemongrass oil internally carries serious toxic risks with it such as connation injury and irritation of the mucous membranes. Serious disruption can be expected from concentrated essences where digestive enzymic action and gut flora is concerned. The safe use is only to be administered in consultation with a working professional, to a dilution of .1% (1 part essential oil to 1000 parts vehicle) in adult cases. It is contraindicated in pregnancy, or in cases of certain systemic medications which may antagonize the effects of Lemongrass.
Applying higher concentrations of lemongrass oil provides more effective and faster therapeutic healing results.
Exceeding recommended dilution ratios (typically 0.5-2% for skin) causes chemical burns, sensitization, and compromised skin barrier function. Higher concentrations don't accelerate benefits but increase toxicity risks. Effective dosing follows saturation thresholds where additional oil provides diminishing returns while multiplying adverse reaction probabilities.
Lemongrass essential oil also provides immediate relief from anxiety with the first inhalation/ application.
The experience of lessening anxiety is cumulative by virtue of continuous use of essential oils in aromatherapy from week to week. The limbic system becomes used to the resultant calming qualities of the citrus compounds through neuroplastic adjustment rather than through immediate reactions to the chemicals. The initial application will produce slight relaxation but the balancing of mood vibrations takes place through the repeated stimulation of the olfactory sense and subsequent reaction of the body systems through both behavioural and vibronic orientation.
Conclusion
The health benefits of lemongrass oil are versatile, spanning skin care to pain relief. Its natural compounds produce effects on multiple systems of the body. It should also be noted that there are limits to the studies. The testing conducted so far suggests potential benefits. It merits attention, but more extensive trials involving humans are needed to establish conclusively whether these effects exist.
Always follow safety guidelines for best results. Mix and dilute oils properly: 0.5-2% for skin and 1 drop per cup for tea. Do not take essential oils during pregnancy or with certain medications. Seek out experts (your doctor) for safe advice before beginning a new wellness program, especially with conditions already present.
Integrate lemongrass oil holistically into daily life. Add 5 drops to your morning diffuser for an energy boost. Use diluted oil for evening massages. Create weekly detox baths with Epsom salts. These simple habits build comprehensive wellness naturally over time.
