Dispelling the Myth: Lemongrass Promotes Rest
Many assume that lemongrass, with its bright, citrusy flavor, must be stimulating like a morning cup of coffee. However, this is a misconception. Lemongrass is a herbal powerhouse that is entirely caffeine-free, making it an excellent choice for a soothing nighttime beverage. For centuries, traditional medicine practitioners have used it for its mild sedative effects to ease anxiety and promote a sense of calm. Instead of keeping you awake, its properties work to signal to your body that it's time to relax and wind down for sleep.
The Science Behind Its Sedative Effects
The calming properties of lemongrass are primarily attributed to its natural compounds. Research, including some animal and laboratory studies, has highlighted the potential anxiolytic (anxiety-reducing) and sedative effects of compounds such as citral and myrcene found in lemongrass. These compounds may interact with the body's nervous system, promoting a state of calm. For example, some studies suggest that lemongrass extracts may affect GABAergic pathways, which are involved in regulating anxiety and sleep. A warm cup of lemongrass tea can help calm the mind and relax muscles, both of which are crucial for preparing the body for a restful night.
How Lemongrass Supports Restful Sleep
Multiple mechanisms contribute to lemongrass's sleep-promoting reputation. First and foremost, the absence of caffeine means there is no stimulant to interfere with your natural sleep cycle. In contrast, many people consume caffeinated drinks late in the day, disrupting their ability to fall asleep. Additionally, the herb's ability to soothe the digestive system can indirectly help with sleep. Lemongrass has traditionally been used to relieve issues like indigestion and bloating, and by eliminating this discomfort, it helps ensure a more peaceful night.
Documented Effects on Sleep Quality
While more human studies are needed to confirm the full range of its sleep benefits, some research is promising. For instance, a 2025 study on postpartum mothers found that drinking a lemongrass and lemon herbal drink significantly improved their sleep quality compared to a control group. Another aspect is the use of lemongrass essential oil. Aromatherapy with lemongrass oil has been shown to produce a relaxing effect, with one study indicating it might positively affect emotional and sensation states. This suggests that even the scent of lemongrass can help prepare the mind and body for sleep.

Incorporating Lemongrass into Your Bedtime Routine
There are several ways to enjoy the soothing benefits of lemongrass for better sleep:
- Lemongrass Tea: The most common method. Brew a cup of fresh or dried lemongrass tea about an hour or two before bed. Simply steep 1-2 teaspoons of dried lemongrass or a couple of fresh stalks in a cup of boiling water for 5-10 minutes.
- Aromatherapy: Use lemongrass essential oil in a diffuser in your bedroom. The calming, citrusy aroma can help create a tranquil atmosphere, easing the mind and promoting sleep.
- Relaxing Bath: Add a few drops of lemongrass essential oil (properly diluted with a carrier oil) to a warm bath for a deeply relaxing soak. This helps soothe muscle tension and prepares your body for rest.
- Massage Oil: Create a simple massage oil by blending diluted lemongrass essential oil with a carrier oil like almond or jojoba. Gently massaging it into your temples, neck, or shoulders can help relieve tension.
Important Precautions and Considerations
While generally safe for most people, some precautions should be taken. Individuals with low blood pressure or low heart rate should use lemongrass with caution, as it can cause a moderate drop in systolic blood pressure. It is also known to have diuretic properties, so a cup too close to bedtime might lead to increased nighttime urination. Women who are pregnant or breastfeeding should avoid consuming lemongrass tea due to limited safety evidence. Always consult with a healthcare professional before adding any herbal remedies to your routine, especially if you take prescription medication.
Conclusion: A Natural Path to Better Sleep
The idea that lemongrass could keep you awake is a clear myth. This naturally caffeine-free herb is, in fact, widely recognized for its ability to promote calmness and relaxation. Through its soothing compounds and traditional use as a mild sedative, incorporating lemongrass into your evening routine—whether through a warm cup of tea or relaxing aromatherapy—can be a natural and effective way to prepare your mind and body for a restful night. While more large-scale human studies are needed, the existing evidence and centuries of anecdotal use point to lemongrass as a valuable tool for supporting better sleep.
