Common Side Effects of Lemongrass Tea
For most people, moderate consumption of lemongrass tea is well-tolerated. However, excessive intake can trigger several side effects. It’s important to be aware of how your body reacts and to not overdo it.
Digestive System Issues
One of the most frequently reported side effects is gastrointestinal distress. Consuming large quantities of lemongrass tea can cause an upset stomach, leading to symptoms such as nausea, abdominal pain, diarrhea, and bloating. This is often due to its potent, natural compounds that can irritate a sensitive digestive system.
Drowsiness and Fatigue
Lemongrass possesses mild sedative properties, which can be beneficial for relaxation. However, for some individuals, this can manifest as unwanted drowsiness, dizziness, or a general feeling of weakness, making it unsuitable for daytime use, especially before driving or operating machinery.
Allergic Reactions
Though uncommon, allergic reactions to lemongrass are possible. Symptoms of an allergic response can range from mild to severe and may include:
- Skin rashes, redness, or itching
- Hives
- Swelling of the face, lips, or throat
- Difficulty breathing
- Respiratory issues like sneezing or wheezing
Dry Mouth and Increased Urination
Lemongrass tea has diuretic properties, meaning it promotes increased urination, which helps flush out excess fluid and toxins. While this is often seen as a benefit, it can also lead to dehydration if fluid intake isn't adequately monitored. Some users also report experiencing dry mouth.
Who Should Avoid Lemongrass Tea?
While a cup of lemongrass tea is a safe and enjoyable drink for many, there are specific groups who should be cautious or avoid it altogether to prevent potential complications.
Pregnant and Breastfeeding Women
This is perhaps the most critical warning. Research has shown that compounds in high concentrations of lemongrass, like citral and myrcene, can have adverse effects and have been traditionally used to stimulate menstrual flow. Therefore, pregnant women, particularly in the first trimester, and those who are breastfeeding should avoid it.
Individuals with Low Blood Pressure
Since lemongrass has been shown to lower blood pressure, those who already have hypotension should be very careful. Overconsumption could cause a dangerous drop in blood pressure, leading to dizziness, weakness, or fainting.
People with Kidney or Liver Problems
High or prolonged consumption of lemongrass tea has been linked to potential adverse effects on kidney function. Individuals with pre-existing kidney or liver disease should consult a healthcare provider before adding lemongrass tea to their routine.
Those on Medication
Lemongrass can interact with certain medications, either by enhancing or reducing their effects. A consultation with a doctor is necessary if you are on any prescription drugs.
Lemongrass Tea vs. Medications: A Comparison
To highlight the importance of consulting a healthcare provider, especially if you are on prescription medication, here is a comparative table of potential drug interactions.
| Medication Class | Potential Interaction with Lemongrass | Precaution |
|---|---|---|
| Antihypertensive Medications | May lower blood pressure further, increasing the risk of hypotension. | Monitor blood pressure closely. |
| Antidiabetic Medications | Can reduce blood sugar, potentially causing hypoglycemia. | Monitor blood sugar levels. |
| Anticoagulants (Blood Thinners) | May increase the risk of bleeding. | Avoid high doses of lemongrass. |
| Diuretics | Can increase urination, potentially causing excessive fluid loss and electrolyte imbalance. | Monitor hydration levels. |
The Importance of Dosage and Moderation
As with most herbal remedies, the dose makes the poison. Most of the reported side effects and negative studies are associated with high, prolonged consumption or concentrated forms like essential oils. For general wellness, it is typically recommended to consume just 1-2 cups of lemongrass tea per day. Starting with a small amount allows you to gauge your body's reaction. Never use herbal remedies to replace prescribed medications without professional medical advice.

What to Do If You Experience Side Effects
If you experience any adverse symptoms after drinking lemongrass tea, stop consumption immediately. Mild reactions like digestive upset may resolve on their own, but severe symptoms such as difficulty breathing or significant drops in blood pressure require immediate medical attention. Always err on the side of caution and consult a healthcare professional for guidance.
Conclusion
While lemongrass tea offers several potential health benefits, understanding its side effects and contraindications is vital for safe consumption. For the average, healthy individual, enjoying 1-2 cups daily is typically safe. However, certain groups, including pregnant women and individuals with low blood pressure or kidney/liver issues, should proceed with caution or avoid it entirely. Always consult a healthcare provider if you have pre-existing conditions or take prescription medication. By practicing moderation and listening to your body, you can minimize risks and safely enjoy the citrusy flavor of this popular herbal tea.
