The Simple Answer: Lemongrass Is Caffeine-Free
For anyone asking, 'is lemongrass high in caffeine?', the straightforward answer is no. As a pure herbal tea or infusion, lemongrass contains absolutely no caffeine. Unlike black, green, or oolong tea, which are derived from the Camellia sinensis plant and naturally contain caffeine, lemongrass comes from a completely different botanical source, the Cymbopogon citratus plant.
This makes it an excellent beverage choice for individuals who are sensitive to caffeine, prefer to avoid stimulants, or are looking for a relaxing drink in the evening. The only time a lemongrass beverage would contain caffeine is if it is part of a blended tea that includes ingredients from the Camellia sinensis plant, such as a lemongrass-green tea mix. In such cases, the caffeine content comes from the added tea leaves, not the lemongrass itself.
The Source of Lemongrass
Lemongrass is a tall, perennial grass native to tropical regions of Asia and Africa. It has a distinct lemon aroma and citrusy flavor that is widely used in Asian cuisine, especially Thai food, as well as in traditional medicine and aromatherapy. The stalk and leaves of the plant are used to make the fragrant, caffeine-free infusion that has become popular worldwide.
Lemongrass vs. Caffeinated Teas
Understanding the fundamental difference between true teas (from Camellia sinensis) and herbal infusions is key to grasping why lemongrass is caffeine-free. While many people colloquially call herbal infusions “tea,” the caffeine content is a major distinguishing factor. The table below provides a clear comparison.
| Beverage | Botanical Source | Typical Caffeine Content | Key Takeaway |
|---|---|---|---|
| Lemongrass Tea | Cymbopogon citratus | 0 mg | Naturally caffeine-free, a relaxing herbal infusion. |
| Black Tea | Camellia sinensis | 40–70 mg per 8-ounce cup | A true tea with moderate to high caffeine content. |
| Green Tea | Camellia sinensis | 20–45 mg per 8-ounce cup | A true tea with less caffeine than black tea, but still caffeinated. |
| Yerba Mate | Ilex paraguariensis | High (comparable to coffee) | An herbal infusion, but one of the few that is naturally caffeinated. |
The Benefits of a Caffeine-Free Herb
Choosing a caffeine-free beverage like lemongrass offers several health and wellness advantages:
- Promotes Relaxation and May Reduce Anxiety: Many find the aroma of lemongrass soothing, and some research suggests that inhaling lemongrass essential oil may have a calming effect. Its use in traditional medicine for its mild sedative properties is well-documented.
- Aids Digestion: Lemongrass has traditionally been used to soothe digestive issues such as upset stomach, cramping, and bloating. It can help stimulate the digestive system and is often consumed after meals for this purpose.
- Rich in Antioxidants: Lemongrass contains several antioxidants, including chlorogenic acid, isoorientin, and swertiajaponin, which help combat free radicals in the body. These compounds may play a role in preventing cell dysfunction.
- Supports Healthy Sleep Patterns: Since it contains no caffeine, a warm cup of lemongrass tea is the perfect addition to a bedtime routine, helping to promote relaxation and prepare the body for sleep without disrupting the natural sleep cycle.
- Supports Oral Health: In some cultures, chewing on lemongrass stalks is practiced for dental hygiene. Studies suggest that lemongrass oil has antibacterial and anti-plaque properties.
How to Enjoy Lemongrass Tea
Preparing a cup of delicious lemongrass tea is simple. You can use either fresh or dried lemongrass.
- Ingredients: 1-2 teaspoons of dried lemongrass (or a 2-inch stalk of fresh lemongrass), 8-10 ounces of filtered water.
- Instructions:
- Bring the water to a boil.
- Add the lemongrass to the water.
- Steep for 5-7 minutes to allow the flavors to infuse.
- Strain the tea and enjoy.
Optional Enhancements:
- For added flavor, try adding a slice of ginger or a squeeze of fresh lemon juice.
- A teaspoon of honey or a natural sweetener can balance the citrusy notes.

Potential Side Effects and Precautions
While generally safe for consumption in food and tea amounts, some precautions are necessary:
- Excessive consumption: Drinking too much lemongrass tea could potentially lead to side effects in some people, such as dizziness, dry mouth, or increased urination.
- Pregnancy: Pregnant individuals should avoid drinking lemongrass tea, as it has been traditionally used to stimulate menstrual flow and may pose a risk during pregnancy.
- Allergies: Some people may have an allergic reaction to lemongrass, with symptoms including a rash or itching.
- Medication Interactions: Individuals with certain health conditions or on medications for low blood pressure or low potassium levels should consult a healthcare provider before use.
Conclusion
In conclusion, lemongrass is unequivocally a caffeine-free herb, providing a flavorful and relaxing beverage option without the stimulating effects of traditional caffeinated drinks. Its use as an herbal infusion, rather than a true tea from the Camellia sinensis plant, is the reason for its zero caffeine content. This makes it an ideal choice for a soothing drink in the evening or a refreshing, healthful alternative for those who wish to avoid stimulants. As with any herbal supplement, it is always wise to consult a healthcare professional, especially for pregnant women or individuals with pre-existing health conditions, to ensure it is right for you.
