Key Groups Who Must Avoid Hibiscus Tea
For many, hibiscus tea is a delicious and healthy beverage, but its potent bioactive compounds mean it is not suitable for everyone. Certain health conditions, life stages, and medication use create significant contraindications. Understanding these risks is vital for safe consumption.
Pregnant and Breastfeeding Individuals
Hibiscus tea is strongly not recommended during pregnancy or while breastfeeding due to its potential to negatively affect hormone levels and trigger uterine activity.
- Hormonal Effects: Hibiscus contains phytoestrogens, which are plant-based compounds that can mimic the hormone estrogen in the body. For a pregnant woman, this can lead to hormonal imbalances that could potentially affect the pregnancy.
- Uterine Stimulation: Some evidence suggests hibiscus tea has emmenagogue properties, meaning it can stimulate blood flow to the uterus and menstruation. This effect increases the risk of miscarriage or premature labor.
- Delayed Puberty: Studies on animal models have shown that consuming hibiscus extract during pregnancy can cause complications like delayed puberty in offspring and an increased risk of obesity.
- Breastfeeding Safety: There is insufficient evidence to determine the safety of hibiscus tea during breastfeeding, so it is best to avoid it to prevent any unknown effects on the infant.
People with Low Blood Pressure (Hypotension)
One of the most well-documented effects of hibiscus tea is its ability to lower blood pressure. While beneficial for individuals with high blood pressure, this presents a significant danger for those with naturally low blood pressure.
- Dangerously Low Levels: For hypotensive individuals, drinking hibiscus tea could cause blood pressure to drop to dangerously low levels.
- Risk of Symptoms: This can cause uncomfortable and potentially unsafe symptoms, such as dizziness, fainting, blurred vision, or fatigue.
Individuals Taking Certain Medications
Hibiscus tea can interact negatively with a range of common medications, altering their effectiveness and potentially causing harmful side effects. If you are on any of the following, avoid hibiscus tea without consulting a healthcare provider:
- Blood Pressure Medications: This includes both ACE inhibitors (e.g., lisinopril) and angiotensin receptor blockers (ARBs) like losartan. The combination could cause blood pressure to drop too low.
- Diuretics: Hibiscus can interfere with how the body processes diuretic drugs such as hydrochlorothiazide, which can lead to complications.
- Diabetes Medications: As hibiscus can lower blood sugar, combining it with diabetes drugs could lead to dangerously low blood sugar levels (hypoglycemia).
- Anti-malarial Drugs: Hibiscus tea has been shown to reduce the effectiveness of chloroquine, a medication used to treat malaria.
- Statins: Some research indicates that hibiscus can reduce the effectiveness of statins like simvastatin by speeding up their elimination from the body.
- Pain Relievers: Consuming hibiscus can increase the rate at which the body eliminates acetaminophen (Tylenol), reducing its effectiveness.
Anyone Allergic to Hibiscus or Mallow Family Plants
Although rare, allergic reactions to hibiscus can occur, especially for individuals with sensitivities to plants in the Malvaceae family, which includes marshmallow. Symptoms can range from mild skin irritations to more severe reactions.
Those Undergoing Surgery
Due to its ability to affect blood sugar levels, consuming hibiscus tea is not recommended in the period leading up to a surgical procedure. To be safe, it is advised to stop consumption at least two weeks before any scheduled surgery.
Individuals with Hormone-Sensitive Conditions
Since hibiscus contains phytoestrogens, individuals with hormone-sensitive conditions such as endometriosis or polycystic ovarian syndrome (PCOS) should avoid or use caution when consuming it. The hormonal effects may exacerbate these conditions.

The Verdict on Hibiscus and Your Health
Hibiscus tea offers potential health benefits for many, such as supporting heart health and providing antioxidants. However, its bioactive nature necessitates caution and informed decision-making for specific populations. The risks associated with pregnancy, low blood pressure, certain medications, and specific conditions are well-documented and should not be ignored.
It is always wise to consult with a healthcare professional before incorporating any new herbal remedy into your routine, especially if you have existing health conditions or are taking prescription medications.
