Hibiscus Tea And Pregnancy: A Safe Combination?

Drinking hibiscus tea is a popular alternative to caffeinated beverages during pregnancy. However, there are concerns about its safety for pregnant women. While some sources claim that it is safe in moderation, others advise against consuming it during pregnancy due to potential risks.

Most of the research on the effects of hibiscus during pregnancy comes from animal studies, which have shown that hibiscus can interfere with hormones and may increase the risk of complications and adverse pregnancy outcomes. These studies have found potential links to delayed puberty in offspring, miscarriage, and altered menstrual cycles.

Due to these findings, experts recommend that pregnant women avoid hibiscus tea until more research is conducted to determine its safety for human consumption during pregnancy.

Hibiscus tea's impact on hormone balance

Hibiscus tea has been shown to have an impact on hormone balance, particularly in women. The tea contains phytoestrogens, which are plant-based estrogens. These compounds can interfere with and alter the body's natural hormone balance, affecting the levels of estrogen in the body. Estrogen is a crucial hormone that regulates almost every aspect of pregnancy, from facilitating the implantation of the fertilised egg to stimulating fetal development.

The impact of hibiscus tea on hormone balance has been observed in several studies, primarily conducted on animals. For example, a study on mice found that high doses of hibiscus extract led to a 92% fetal loss when consumed during pregnancy. Another study on rats showed that hibiscus extract prevented the implantation of the zygote (fertilised egg) in the uterus, acting as a natural contraceptive. Additionally, hibiscus tea has been linked to changes in libido and fertility, menstrual irregularities, and increased risk of miscarriage.

While the research on hibiscus tea's impact on hormone balance is not conclusive, the existing evidence suggests that it can interfere with hormonal balance, particularly in women. As such, it is generally recommended that pregnant women and those trying to conceive avoid consuming hibiscus tea or products containing hibiscus.

Potential to induce labour

While it may be tempting to try and speed up the onset of labour with a cup of hibiscus tea, it is not recommended. Hibiscus tea is known to stimulate uterine contractions, which can induce labour. However, it is not safe to consume during pregnancy and should be avoided altogether.

Judith Lothian, a Ph.D. and childbirth expert, explains that "induction of labour alters the process of labour and birth in significant ways." Instead, it is best to let nature take its course and let your body decide when it's time for labour.

Although the research on the effects of hibiscus during pregnancy is limited and largely based on animal studies, the findings are concerning enough to strongly discourage its consumption in human pregnancy. The studies suggest that hibiscus can cause hormonal imbalances, which can lead to complications during pregnancy, such as miscarriage and preterm labour.

Therefore, it is crucial to avoid hibiscus tea if you are pregnant or trying to conceive, as it may interfere with the implantation of the embryo and increase the risk of adverse pregnancy outcomes.

Miscarriage risk

While the research on hibiscus tea and pregnancy is limited, with most studies conducted on animals, the findings are concerning. Hibiscus tea is believed to have the potential to cause hormonal imbalances, which can lead to an increased risk of miscarriage.

Hibiscus, also known as hibiscus sabdariffa, is a flowering plant native to tropical and subtropical climates. It is often consumed as a hot or cold tea, made by brewing the flower's dried petals. The tea is rich in antioxidants and has several health benefits, including improved liver health, lower blood pressure, and reduced cholesterol levels. However, it is not recommended for pregnant women due to potential risks.

The potential risks of hibiscus tea during pregnancy are mainly related to its impact on hormone balance. Hibiscus contains compounds called phytoestrogens, which can interfere with normal estrogen levels. Estrogen is a crucial hormone that regulates many aspects of pregnancy, such as facilitating the implantation of the fertilized egg and stimulating fetal development. By altering the hormone balance, hibiscus tea may block the implantation of the fertilized egg or trigger a miscarriage, especially during the early stages of the first trimester.

In animal studies, researchers found that treating pregnant animals with hibiscus stopped embryos from implanting into the wall of the uterus, which is essential for a successful pregnancy. Additionally, hibiscus tea has been associated with encouraging the onset of menstruation and mild uterine contractions during the later stages of pregnancy. Consuming large amounts of hibiscus tea can increase the risk of preterm labour during the third trimester.

While the research is limited and based primarily on animal studies, the potential risks are significant enough to warrant caution. As a result, it is generally recommended that pregnant women avoid consuming hibiscus tea to mitigate any potential risks to themselves and their unborn child.

It is important to note that the majority of commercially sold hibiscus teas contain far lower concentrations of hibiscus extract than those used in the studies. However, due to the potential risks, it is advisable for pregnant women to avoid hibiscus tea altogether.

Lack of human studies

While there is some research on the effects of hibiscus on pregnancy, most of it is based on animal studies. Human studies are lacking, and the few that exist are small-scale.

The information on hibiscus and pregnancy is based on a single study that gave mice high doses of hibiscus extract, resulting in loss of pregnancy. However, the dosage given to the mice was extremely high—the equivalent of a 60kg woman consuming 60g of hibiscus per day. In contrast, a typical cup of hibiscus tea contains only a fraction of this amount, and one would need to consume an extremely large quantity of hibiscus tea to reach the same dosage as the mice in the study.

The lack of human studies makes it challenging to draw definitive conclusions about the safety of hibiscus tea during pregnancy. While some sources advise avoiding hibiscus tea altogether during pregnancy, others suggest limiting intake to 2-4 cups per day as a precautionary measure.

The existing human studies on hibiscus and pregnancy have shown a potential correlation with certain hormonal changes, specifically with estrogenic properties. Hibiscus may influence and regulate hormones, which could explain the higher risk of complications and adverse pregnancy outcomes found in animal studies. However, more human studies are needed to confirm these findings.

Safe alternatives to hibiscus tea

While hibiscus tea is a delicious and nutritious drink, it is best avoided during pregnancy. The good news is that there are plenty of other herbal teas that are safe to consume while pregnant. Here are some safe alternatives to hibiscus tea:

• Peppermint tea: This herbal tea can help ease digestive discomfort during pregnancy, such as reflux and bloating. It is best to avoid peppermint tea during the first trimester.
• Rosemary tea: This herb has a refreshing aroma and flavour and is safe to consume in moderation during pregnancy.
• Bitter orange tea: A moderate amount of bitter orange tea is safe during pregnancy.
• Red raspberry leaf tea: This tea may help prepare the uterus for labour and should only be consumed during the last trimester. It is important to get a doctor's approval before consuming this tea.
• Ginger tea: Ginger tea is known to reduce morning sickness during the early stages of pregnancy. It is also packed with antioxidants and is generally considered safe to consume during pregnancy.
• Lemon balm tea: This calming tea relaxes the central nervous system and is beneficial for anxious women, especially before labour.
• Rooibos tea: This caffeine-free tea is rich in antioxidants and other beneficial phytochemicals. It is a great alternative to hibiscus tea, providing similar health benefits without the risks.
• Rose tea: Rose tea is a rich source of vitamin C and health-promoting antioxidants. It is generally considered safe to consume during pregnancy.

While these herbal teas are believed to be safe during pregnancy, it is always recommended to consult your doctor or healthcare provider before consuming any new drinks or supplements to ensure they are right for your individual needs.
