Who Should Avoid Lemon Balm Tea?
Though generally considered safe for most healthy adults in moderation, lemon balm tea carries significant risks for specific groups of people. It's crucial to understand these contraindications before incorporating this herbal remedy into your routine. This is especially true for those with pre-existing medical conditions, individuals taking prescription medications, and those in sensitive life stages like pregnancy.
Individuals with Thyroid Disorders
One of the most important warnings regarding lemon balm tea concerns individuals with thyroid issues. The herb has been shown to potentially interfere with thyroid function. Specifically, it may affect thyroid hormone levels and block the binding of Thyroid-Stimulating Hormone (TSH).
- Hypothyroidism and Hashimoto's Thyroiditis: For those with an underactive thyroid (hypothyroidism) or the autoimmune condition Hashimoto's, lemon balm can be particularly problematic. It may slow down thyroid function further, worsening symptoms. Individuals on thyroid hormone replacement therapy, such as levothyroxine, should be aware that lemon balm may reduce the effectiveness of their medication.
- Graves' Disease: In some cases, lemon balm has been used to help manage hyperthyroidism (overactive thyroid) by suppressing thyroid function. However, this should only be done under strict medical supervision, as incorrect dosage or long-term use can still pose risks.
Pregnant and Breastfeeding Women
The scientific community has not conducted enough research to definitively establish the safety of lemon balm for pregnant and breastfeeding women. Due to this lack of reliable information, health experts recommend that both pregnant and lactating individuals avoid the tea entirely to stay on the safe side. Some traditional uses exist, and some sources note its potential to help with nausea in early pregnancy, but the potential for risks, such as its antispasmodic properties potentially interfering with uterine contractions in the third trimester, makes it a risky choice without a doctor's explicit approval.
Children Under 12
While some research has explored the use of lemon balm in children, there is limited data on its long-term safety, especially for younger children. The European Medicines Agency does not recommend using lemon balm medicinally in children under 12 due to this lack of data. It's crucial to consult a pediatrician before giving lemon balm tea to a child.
Individuals Taking Specific Medications
Lemon balm has the potential to interact with several classes of medications, leading to potentially dangerous side effects.
Sedatives and Central Nervous System (CNS) Depressants
Because lemon balm possesses natural sedative and calming properties, combining it with other sedatives can lead to excessive drowsiness, dizziness, and even slowed breathing. This includes prescription drugs for insomnia (like zolpidem), anti-anxiety medications (like lorazepam), and even over-the-counter antihistamines that cause sleepiness. Alcohol also falls into this category, and using it with lemon balm is not recommended.
Glaucoma Medications
Some research has indicated that a volatile component of lemon balm, citral, might increase intraocular pressure. While the evidence is mostly from animal studies and the effect in humans is theoretical, the risk is significant enough that individuals with glaucoma or those taking medications to manage it (such as travoprost) should avoid lemon balm.
HIV Antiretroviral Medications
There is some evidence to suggest that lemon balm could interfere with the effectiveness of certain antiretroviral drugs used to treat HIV. The research is not fully clear, but given the critical nature of these treatments, it is recommended to avoid lemon balm while on HIV medication unless advised otherwise by a doctor.
Pre-Surgery Patients
Due to its sedative effects, lemon balm can interact with anesthesia and other medications used during and after surgery. Healthcare providers recommend stopping all consumption of lemon balm at least two weeks before a scheduled surgical procedure to prevent adverse reactions.
Those with Allergies to the Mint Family
As a member of the mint family, lemon balm may cause allergic reactions in individuals with sensitivities to related plants. Symptoms might include skin redness, rashes, or other irritations. It's best to avoid the tea if you have a known allergy to any plant in the mint family.

|---|---|---|
| Healthy Adults | Yes, in moderate amounts | No specific reason, unless experiencing side effects |
| Thyroid Disease | No | Hypothyroidism, Hashimoto's, Graves' disease, or on thyroid medication |
| Pregnancy/Lactation | No | All stages of pregnancy and during breastfeeding due to lack of safety data |
| Children | Consult a pediatrician | Generally not recommended for regular use in children under 12 without medical advice |
| Sedative Medications | No | Sleep aids, anti-anxiety drugs, and alcohol |
| Glaucoma | No | Glaucoma or on glaucoma medications due to risk of increased intraocular pressure |
| HIV Medication | No | Taking antiretroviral medications due to potential interactions |
| Scheduled Surgery | No | Within two weeks of a procedure due to sedative effects |
| Low Blood Pressure (Hypotension) | Consult a doctor | Individuals with hypotension should exercise caution, as lemon balm can lower blood pressure |
Conclusion: Prioritize Professional Medical Advice
While lemon balm tea can be a relaxing and beneficial beverage for many, it is not suitable for everyone. The herb’s effects on the body are not purely benign, and its interactions with certain medical conditions and medications can be problematic, if not dangerous. The potential risks for individuals with thyroid disorders, glaucoma, or those taking sedatives or HIV medication are particularly significant. Furthermore, the lack of sufficient safety research makes it inadvisable for pregnant or breastfeeding women and children. Before starting any herbal remedy, including lemon balm tea, it is always best to consult with a healthcare provider to ensure it is a safe and appropriate choice for your specific health situation.
