4 min read

A 2021 review of studies noted that lemongrass extracts and essential oils show anti-hypertensive effects in both animal and human models, indicating its powerful biological activity. While lemongrass tea offers numerous health benefits, understanding the potential side effects of drinking lemongrass tea every day is crucial for safe, informed consumption.

Quick Summary

Excessive intake of lemongrass tea can cause side effects such as dizziness, increased urination, dry mouth, and digestive upset. Individuals with pre-existing health conditions, especially those related to blood pressure, kidneys, or liver, should exercise caution and consult a healthcare professional. Allergic reactions, medication interactions, and contraindications during pregnancy and breastfeeding are also important considerations for daily use.

Key Points

  • Moderate Intake: For most healthy adults, 1-2 cups of lemongrass tea daily is considered safe, but excessive consumption increases the risk of side effects.

  • Diuretic Effects: The tea can increase urination, and over-consumption without adequate hydration may lead to dehydration.

  • Blood Pressure Impact: Lemongrass can lower blood pressure, making it unsuitable for individuals who already have low blood pressure or take blood pressure medication.

  • Contraindications: Pregnant or breastfeeding women, and individuals with liver or kidney issues, should avoid lemongrass tea or use it only under a doctor's supervision.

  • Medication Interactions: Lemongrass can interfere with certain medications, including blood thinners and diabetes drugs; medical consultation is necessary if you are on medication.

  • Allergic Reactions: Though rare, allergies can occur, with symptoms like rashes and itching.

  • Digestive Discomfort: High intake can lead to gastrointestinal issues such as nausea, bloating, or diarrhea.

Understanding the Benefits and Risks of Daily Lemongrass Tea

Lemongrass tea has earned a reputation as a health-boosting beverage, celebrated for its antioxidant and anti-inflammatory properties. A daily cup is a soothing ritual for many, but like any potent herb, its consistent, daily consumption warrants a closer look at potential drawbacks. Understanding the spectrum of effects is the key to enjoying this herbal infusion safely.

Common Side Effects of Daily Lemongrass Tea Intake

For most healthy adults, a moderate amount of lemongrass tea daily (typically 1-2 cups) is considered safe. However, excessive consumption, or sensitivity to the herb, can lead to several noticeable side effects. Some of the most frequently reported issues include:

  • Digestive Upset: Some individuals experience nausea, stomach discomfort, or diarrhea when consuming large quantities of lemongrass tea. This can be due to its high concentration of bioactive compounds affecting the gastrointestinal tract.
  • Increased Urination (Diuretic Effect): Lemongrass is a natural diuretic, meaning it increases the frequency of urination. While this can help flush excess fluids, excessive daily intake can lead to dehydration if not balanced with sufficient water consumption.
  • Drowsiness and Dizziness: Due to its mild sedative properties, lemongrass tea can cause drowsiness or dizziness in some people, particularly when consumed in higher doses. It is advisable to avoid consuming large amounts before driving or operating heavy machinery.
  • Dry Mouth: This is another commonly reported side effect linked to frequent lemongrass consumption. The diuretic effect may play a role in this symptom.
  • Increased Appetite: In some cases, individuals may experience a noticeable increase in hunger, though the exact mechanism for this is not fully understood.

Important Contraindications and Precautions

Beyond general side effects, certain individuals should avoid or limit their intake of lemongrass tea due to specific health conditions or life stages. Medical guidance is essential in these cases.

Who should not drink lemongrass tea?

  • Pregnant and Breastfeeding Women: Lemongrass is not recommended during pregnancy or breastfeeding. In large doses, it may stimulate uterine contractions and menstrual flow, increasing the risk of miscarriage. The effects on infants are not well-studied, so caution is advised.
  • Individuals with Low Blood Pressure: As a hypotensive agent, lemongrass can significantly lower blood pressure. Those with already low blood pressure should avoid it to prevent a dangerous drop that could lead to weakness or fainting.
  • Those with Kidney or Liver Problems: The detoxifying effect of lemongrass can put additional strain on the kidneys and liver. People with pre-existing conditions affecting these organs should consult a doctor before consumption.
  • People on Certain Medications: Lemongrass tea can interact with various prescription drugs, including blood thinners, blood pressure medication, and diabetes drugs, altering their effectiveness. The citral in lemongrass can also induce certain liver enzymes (CYP450) that metabolize drugs.
  • Individuals with Allergies: Although rare, some people may have an allergic reaction to lemongrass, experiencing symptoms like rashes, itching, or difficulty breathing.

Lemongrass Tea vs. Lemongrass Essential Oil Toxicity

It is critical to distinguish between consuming lemongrass tea and ingesting lemongrass essential oil. Essential oils are highly concentrated and can be toxic if consumed in large amounts, potentially causing damage to the liver and stomach lining. The risk of these severe effects is significantly lower with brewed tea, but still emphasizes the importance of moderation.

Aspect Daily Lemongrass Tea Consumption Daily Lemongrass Essential Oil Use (Internal)
Toxicity Level Generally low for moderate amounts; higher risk with excessive intake. High; can cause significant internal damage.
Risk of Side Effects Mild to moderate side effects possible, such as dizziness, digestive upset, and increased urination. Severe side effects including liver and stomach damage.
Medication Interaction Possible interactions with blood pressure, diabetes, and blood thinner medications. Higher risk of severe drug interactions due to high concentration.
Pregnancy Safety Not recommended due to potential to stimulate uterine flow. Likely unsafe due to concentrated compounds that could harm embryo.
Recommended Use Up to 1-2 cups per day for most healthy adults, with a doctor's consultation for specific health issues. Not for internal use. Only for aromatherapy or topical application (diluted).

Best Practices for Safe Consumption

To minimize the risks and maximize the benefits, consider these guidelines for incorporating lemongrass tea into your daily routine:

  • Start with Small Amounts: If you are new to lemongrass tea, begin with a single cup per day to see how your body reacts before increasing your intake.
  • Consult a Professional: Always speak with a healthcare provider, especially if you have pre-existing health conditions, are pregnant, breastfeeding, or taking any prescription medications.
  • Monitor Your Body's Response: Pay close attention to any changes or symptoms, such as dizziness, stomach upset, or changes in blood pressure, and adjust your consumption accordingly.
  • Choose High-Quality Products: Ensure you are using high-quality, reputable lemongrass products to avoid potential contaminants.
  • Moderation is Key: The benefits of lemongrass tea are best reaped through moderate, mindful consumption. Avoid treating it as a quick fix or consuming excessive quantities.

Conclusion

Lemongrass tea offers a pleasant flavor and potential health benefits, but its daily consumption is not without potential side effects, particularly for those with certain health concerns or sensitivities. The herb's natural diuretic, hypotensive, and sedative properties mean moderation is crucial. While a couple of cups per day may be safe for many, pregnant and breastfeeding women, those with specific health conditions affecting the heart, kidneys, or liver, and individuals on certain medications should proceed with caution and professional medical advice. By understanding the risks and practicing sensible consumption, you can enjoy the aromatic and therapeutic qualities of lemongrass tea safely. A healthcare consultation remains the most important step for anyone considering it as a regular part of their diet, ensuring it complements rather than compromises their health goals. For further information on herbal interactions, consult reliable medical sources like the Memorial Sloan Kettering Cancer Center.
