Who can not drink hibiscus tea? A Guide to Contraindications

While many praise its health benefits, a significant portion of the population should avoid hibiscus tea to prevent adverse effects. The seemingly harmless herbal brew can pose risks to individuals with certain health conditions or those taking specific medications.

Quick Summary

Certain individuals should avoid hibiscus tea, including pregnant and breastfeeding women, those with low blood pressure, and people on specific medications. It can also cause issues for allergy sufferers and those with kidney or liver concerns.

Key Points

• Pregnancy and Breastfeeding: Hibiscus tea is potentially unsafe for pregnant women due to its emmenagogue effect, which can stimulate menstruation. It is also not recommended for breastfeeding mothers.

• Medication Interactions: Hibiscus can interact with medications for high blood pressure, diabetes, and malaria, altering their effectiveness.

• Low Blood Pressure (Hypotension): As a natural antihypertensive, hibiscus can lower blood pressure further in individuals with existing low blood pressure.

• Allergy to Hibiscus: Although rare, some individuals may have an allergic reaction to hibiscus or related plants in the Malvaceae family.

• Before Surgery: Consumption should be stopped at least two weeks before any scheduled surgery, as it can affect blood sugar levels.

• High Doses and Liver Health: Excessive intake of hibiscus extract has been linked to potential liver toxicity in animal studies.

The Primary Groups Who Must Avoid Hibiscus Tea

Hibiscus tea, derived from the dried Hibiscus sabdariffa flower, is known for its tart flavor and potential health benefits, such as antioxidant properties. However, its powerful nature means it's not suitable for everyone. For some, the risks outweigh the rewards, making it essential to understand the contraindications.

Pregnant and Breastfeeding Women

Medical experts and animal studies strongly advise pregnant women to avoid hibiscus tea. The primary concern is its emmenagogue effect, which means it can stimulate menstrual flow. This can increase the risk of miscarriage or early labor, especially when consumed in large quantities. Furthermore, the phytoestrogens in hibiscus may interfere with hormonal balance during pregnancy. The safety of hibiscus tea during lactation is also unclear, with some sources recommending caution or avoidance as a precaution. Given the potential risks, it is best to err on the side of caution and abstain from hibiscus tea during pregnancy and breastfeeding.

Individuals on Specific Medications

The active compounds in hibiscus tea can interact with various prescription medications, affecting their efficacy or causing adverse reactions. This makes it crucial for those on medication to consult a healthcare provider before consuming hibiscus tea.

Potential Drug Interactions

• Blood Pressure Medications (Antihypertensives): Hibiscus tea is a known antihypertensive and diuretic. Combining it with blood pressure-lowering drugs like diuretics (e.g., hydrochlorothiazide) or ACE inhibitors (e.g., lisinopril) can cause blood pressure to drop too low, leading to hypotension,.
• Diabetes Medications: Hibiscus tea has shown the ability to lower blood sugar levels. For individuals taking anti-diabetes drugs, combining it with hibiscus could lead to hypoglycemia (dangerously low blood sugar).
• Anti-malarial Drugs: Studies have indicated that hibiscus tea may decrease the absorption and effectiveness of the anti-malarial drug chloroquine.
• Other Medications: Hibiscus can affect how the liver processes certain medications, including some for pain and high cholesterol, potentially altering their effects or side effects.

People with Low Blood Pressure (Hypotension)

As hibiscus tea has significant blood pressure-lowering properties, it is not suitable for individuals who already have low blood pressure. Regular consumption could exacerbate the condition, leading to symptoms such as dizziness, fainting, or fatigue.

Those with Allergies to Hibiscus

While uncommon, some people can have an allergic or sensitive reaction to hibiscus or other plants in the Malvaceae family (which includes marshmallow plants). Symptoms can range from dermatitis and hives to headaches and nausea. If you have a known sensitivity to similar plants, or experience an adverse reaction, discontinue use immediately.

Who Should Use Caution or Consult a Doctor?

Individuals Undergoing Surgery

Due to its potential to affect blood sugar and blood pressure, anyone scheduled for surgery should stop consuming hibiscus tea at least two weeks beforehand. This helps ensure stable blood glucose and blood pressure levels during and after the procedure.

Young Children and Infants

There is limited research on the safety of hibiscus tea for children under 12. Some pediatricians may suggest avoiding it due to insufficient data. Small amounts may be considered for older children, but it's important to consult with a healthcare provider and monitor any effects. Infants should not be given hibiscus tea.

Individuals with Kidney Concerns

While hibiscus tea has diuretic properties that can help with kidney health, it also contains oxalates. In excessive amounts, these can contribute to the formation of kidney stones in susceptible individuals. People with a history of kidney stones or kidney disease should consult a doctor before making hibiscus tea a regular part of their diet.

How to Identify Risk and Stay Safe

To ensure your safety, it's vital to know your own health conditions and what medications you are taking. Here is a brief checklist and some simple guidelines:

• Consult a Healthcare Provider: If you have any pre-existing health conditions or are taking prescription medication, a consultation with your doctor is non-negotiable before starting a regular hibiscus tea regimen. This includes blood pressure issues, diabetes, and kidney problems.
• Monitor Your Body's Response: When trying any new herbal supplement, including hibiscus tea, start with a small amount. Pay close attention to how your body reacts. Look for any signs of an allergic reaction or unexpected symptoms like dizziness.
• Avoid Excessive Intake: Even for healthy adults without contraindications, extremely high doses of hibiscus extract have been linked to potential liver issues in animal studies. Stick to moderate consumption, generally 1-2 cups per day, as recommended.
• Check Ingredients in Blends: Many commercial herbal teas include hibiscus. Always read the ingredient list carefully, especially if you are in a high-risk group.

Conclusion: Prioritize Safety Over Herbal Remedy

While hibiscus tea offers a range of potential health benefits, it is not a universally safe beverage. Pregnant or breastfeeding women, individuals with low blood pressure, and those on specific medications for blood pressure, diabetes, or malaria should strictly avoid it. Other groups, such as children and those with kidney concerns, must exercise caution and seek professional medical advice. Always prioritize your health and consult a doctor to ensure that this herbal tea is a safe choice for you.
