What is Lemongrass?
Lemongrass is a tropical, perennial plant known botanically as Cymbopogon. While there are many species, Cymbopogon citratus is the most common variety used for culinary and medicinal purposes. The leaves and oily stalks of the plant are prized for their potent, citrusy flavor and scent. From fragrant teas to a staple ingredient in Southeast Asian cuisine, lemongrass is a versatile plant. However, its use extends far beyond the kitchen into the world of herbal remedies and aromatherapy.
The Benefits: Why Lemongrass Can Be Good
Lemongrass contains several bioactive compounds, including citral, flavonoids, and phenolic compounds, that contribute to its positive health effects. Incorporating it into your diet or using its essential oil can provide a range of advantages.
Potential Health Perks
- Antioxidant and Anti-inflammatory Properties: The flavonoids and phenolic compounds in lemongrass act as powerful antioxidants, helping to neutralize free radicals that cause oxidative stress and cellular damage. Chronic inflammation is a factor in many diseases, and the anti-inflammatory effects of lemongrass may help combat this.
- Digestive Aid: Traditionally used to soothe stomach issues, lemongrass tea can help calm an upset stomach, bloating, and cramps. Studies on rodents have also shown its potential to protect the stomach lining from damage.
- Relieves Anxiety: The aroma of lemongrass essential oil is believed to have a calming effect, and inhaling it may reduce anxiety. Some research suggests it can promote relaxation and mental clarity.
- Boosts Oral Health: Chewing on lemongrass stalks is a traditional practice for improving dental health. Studies have shown that lemongrass oil mouthwash can reduce plaque and gingivitis.
- Lowers Blood Pressure: Some research suggests that the citral in lemongrass can help lower blood pressure by widening blood vessels and promoting fluid excretion.
- Antimicrobial Effects: Lemongrass essential oil has shown antibacterial and antifungal properties in laboratory studies, effective against certain bacteria like E. coli and fungi like Candida albicans.
The Risks: When Lemongrass Can Be Bad
Despite its many benefits, lemongrass is not without its risks. The potential for harm depends heavily on the form, dosage, and individual health factors.
Potential Side Effects and Interactions
- Allergic Reactions: Some individuals may have an allergic reaction to lemongrass, with symptoms including skin rashes, itching, or respiratory distress.
- Pregnancy and Breastfeeding Concerns: Lemongrass is considered likely unsafe when taken orally in large amounts during pregnancy, as it can stimulate menstrual flow and potentially cause a miscarriage. Due to a lack of reliable information, it is best to avoid during breastfeeding as well.
- Drug Interactions: Lemongrass can interact with certain medications. For example, it can potentially lower blood sugar, which is a risk for diabetics on medication. It can also interact with sedatives and medications metabolized by the liver, altering their effects.
- Essential Oil Toxicity: Lemongrass essential oil should never be ingested or applied directly to the skin without being properly diluted. There have been reports of toxic side effects from misuse, such as lung problems from inhalation. High oral doses can also potentially damage the liver.
- Excessive Tea Consumption: Drinking too much lemongrass tea can lead to side effects such as dry mouth, dizziness, fatigue, and increased appetite.

Safe and Delicious Ways to Use Lemongrass
For most healthy adults, incorporating lemongrass into your diet is safe and enjoyable. The key is moderation and using the correct form for the intended purpose.
Preparing Lemongrass for Culinary Use
- To use the stalks in soups or curries, trim the very end and peel off any dry outer layers.
- Gently bruise the stalk with the flat side of a knife to release its aromatic oils.
- You can add the whole stalk to a dish and remove it before serving, or finely chop the tender inner part for marinades or pastes.
Brewing a Soothing Tea
- Ingredients: 1-3 teaspoons of fresh or dried lemongrass per cup of boiling water.
- Method: Steep for 5-10 minutes, then strain. You can enjoy it hot or iced. Start with one cup a day to see how your body reacts before increasing.
Using Lemongrass Essential Oil Safely
- Aromatherapy: Use 3-4 drops in a diffuser to enjoy its calming and stress-relieving scent.
- Topical Application: Always dilute with a carrier oil like coconut or almond oil before applying to the skin. Perform a patch test first to check for allergic reactions.
Conclusion
So, is lemongrass good or bad? The answer is nuanced. For most people, when used moderately in culinary applications or as a tea, lemongrass is a beneficial and flavorful herb. Its antioxidant, anti-inflammatory, and digestive properties are well-regarded and supported by both traditional and modern understanding. However, its potential for side effects, drug interactions, and specific contraindications, especially for pregnant women, means it is not universally safe for everyone. Always listen to your body and consult a healthcare professional before using lemongrass for medicinal purposes, particularly in concentrated forms like essential oils or high-dose supplements.
