Common Side Effects of Lemongrass Water
For most people, moderate consumption of lemongrass water or tea is safe and well-tolerated. However, drinking excessive amounts can lead to several adverse reactions. Some of the most commonly reported side effects include:
Digestive Issues
While often used to soothe digestive problems, excessive lemongrass can sometimes have the opposite effect. Some individuals may experience stomach upset, nausea, or stomach pain, especially if they are not used to herbal teas or consume it on an empty stomach. The potent compounds can irritate the stomach lining in large doses.
Dizziness and Fatigue
Lemongrass contains compounds with sedative properties, which can lead to feelings of drowsiness and fatigue in some people. While this can be beneficial for relaxation and sleep, it can be a problem if experienced during the day, particularly when driving or operating machinery. Dizziness is another reported side effect, especially with high intake.
Increased Urination and Dehydration
Lemongrass is a known diuretic, meaning it increases the frequency of urination. While this can help flush out toxins, excessive fluid loss can lead to dehydration or imbalances in electrolytes like potassium and sodium. This effect can put additional strain on the kidneys.
Allergic Reactions
Although uncommon, allergic reactions to lemongrass are possible. Symptoms can range from mild skin rashes and itching to more severe respiratory distress, such as difficulty breathing. If you notice any signs of an allergic reaction, stop consumption immediately and seek medical attention.
Increased Appetite
Some individuals have reported an increase in appetite after consuming lemongrass water. For those who use lemongrass as a weight-loss aid, this potential side effect could counteract their goals.
Who Should Avoid Lemongrass Water?
Certain individuals should be particularly cautious or avoid lemongrass water altogether due to specific health risks:
- Pregnant and breastfeeding women: Lemongrass may stimulate uterine contractions and menstrual flow, potentially leading to miscarriage. It is considered likely unsafe during pregnancy, and its safety during breastfeeding is not well-established.
- People with low blood pressure: Since lemongrass can lower blood pressure, those with already low blood pressure (hypotension) or those on blood pressure medication should be cautious. Excessive consumption could cause blood pressure to drop to unsafe levels, leading to dizziness, weakness, or fainting.
- Individuals with kidney or liver problems: The diuretic and detoxifying effects of lemongrass can place additional strain on the kidneys and liver. Anyone with pre-existing kidney or liver conditions should consult a doctor before use.
- Children: There is insufficient information on the safety of lemongrass for children under 18.
Potential Drug Interactions
Lemongrass can interact with various medications, altering their effectiveness or increasing the risk of side effects. It is crucial to consult a healthcare provider if you are taking any medication.
- Anticoagulant and blood thinner medications: As lemongrass may have blood-thinning properties, combining it with medications like warfarin or aspirin could increase the risk of bleeding.
- Medications for diabetes: Lemongrass might lower blood sugar levels. For those on antidiabetic medications, this could cause blood sugar to drop too low, resulting in hypoglycemia.
- Blood pressure medications: The blood pressure-lowering effect of lemongrass can enhance the effects of antihypertensive drugs, potentially causing hypotension.
- Sedative medications: Combining lemongrass with other sedatives, like pentobarbital, might increase sleepiness and other side effects.
- Medications metabolized by the liver (CYP450 substrates): Lemongrass may affect the liver enzymes that break down certain drugs, potentially changing their effects and side effects.
How to Consume Lemongrass Safely
To minimize risks and maximize benefits, follow these guidelines:
- Start small: Begin with a small amount, like one cup of tea a day, to see how your body reacts before increasing intake.
- Stick to culinary amounts: Consume lemongrass water in moderation. Avoid large, concentrated doses or using essential oils internally.
- Listen to your body: Pay attention to any unusual symptoms. If you experience discomfort, stop use immediately.
- Consult a doctor: If you have any pre-existing health conditions or are on medication, discuss it with your healthcare provider first.

| Feature | Moderate Consumption (1-2 cups/day) | Excessive Consumption (High, regular doses) |
|---|---|---|
| Digestive Impact | Aids digestion, soothes bloating | Can cause stomach upset, nausea, and pain |
| Energy/Alertness | Calming, may promote relaxation | Can cause drowsiness, dizziness, and fatigue |
| Urination | Mild diuretic effect, helps detoxification | Excessive urination, potential for dehydration |
| Appetite | No significant effect reported | May increase appetite |
| Health Risks | Generally safe for most individuals | Increased risk of complications, especially for at-risk groups |
Conclusion
While lemongrass water offers a variety of health benefits, such as aiding digestion and providing antioxidants, it is not without potential risks. The side effects of lemongrass water, particularly with excessive consumption, can include digestive issues, fatigue, dizziness, and dehydration. Certain individuals, including pregnant women, those with low blood pressure, and those on specific medications, should approach its use with caution or avoid it entirely. By consuming it in moderation and being aware of potential contraindications and drug interactions, most people can enjoy lemongrass water safely. It is always best to consult with a healthcare provider before adding a new herbal remedy to your routine, especially if you have an underlying health condition. The Memorial Sloan Kettering Cancer Center offers extensive information on the potential uses and side effects of lemongrass, emphasizing the importance of caution and professional guidance.
