Can Hibiscus Tea Affect Estrogen?

Hibiscus, also called roselle or sorrel, is a flowering plant best-known for the tea that’s typically made from its flowers. Its flowers, seeds, stems, and leaves are edible, and have been used in foods and traditional medicine for many years, according to Cleveland Clinic.
Hibiscus is believed to have numerous health benefits and is generally considered safe. It is also known to affect estrogen, though research to determine the full potential of the plant is ongoing, according to a study.
Hibiscus Flowers
Many hibiscus species produce bright red flowers. The fresh or dried calyxes, or protective outer whorls of these flowers, are made into hot herbal infusions or cold beverages with a sweet, tangy flavor in a variety of countries, according to a study.
Teas sold by the bag are most common in the United States. You can also find iced, sweetened agua de Jamaica in Mexican restaurants, and sorrel, which is a sweetened hibiscus infusion mixed with spices and served cold, in Caribbean eateries.
Medicinal properties of hibiscus flowers and leaves include reducing inflammation, lowering blood pressure and cholesterol, stimulating weight loss, and supporting liver health, according to Cleveland Clinic. Hibiscus also contains antioxidants, including beta-carotene (vitamin A), vitamin C, and anthocyanin, a plant pigment.
Impact on Estrogen
The specific estrogen-like element of hibiscus is still unknown. But research suggests that hibiscus has the ability to mimic or enhance estrogen in the body. Hibiscus contains phytoestrogens, or plant-based estrogens.
One study looked at rats without ovaries. The study indicated that hibiscus extract lessened the negative effects of the ovary removal on the rats’ memory function. The authors suggest that more research should be done on using hibiscus as an alternative to synthetic hormone replacement therapy in menopause.
Hibiscus Root
The roots of the Hibiscus sabdariffa L. shrub can potentially fight cancerous tumors, research suggests. And the roots of the Hibiscus rosa-sinensis Linn. shrub have long been used in traditional medicine, according to study. In Malaysia, they’ve been used to treat sexually transmitted infections and fever. In Nepal, they’ve been used as a cough treatment. And in India, they’ve been used as an abortion drug.
Recommendations
Various parts of the hibiscus plant have been used in traditional medicine as a form of birth control for thousands of years, according to a research review. And scientific studies provide evidence for its effectiveness.
Women who are pregnant should play it safe and avoid drinking hibiscus tea, according to Banner Health, a healthcare system in Arizona. It can cause miscarriage or make it harder to control blood sugar levels during pregnancy. The effectiveness of using hibiscus products as a form of birth control has not been compared with conventional methods in research. So, opt for birth control that has been approved by the U.S. Food and Drug Administration to prevent pregnancy.
