author avatar Dr. Eric Berg 04/02/2024

Hibiscus flowers are rich in antioxidants. They have been found to promote healthy blood vessels, and evidence suggests that drinking hibiscus tea may help lower blood pressure naturally.

Discover the health benefits of hibiscus and learn how to make hibiscus tea for high blood pressure.

What is hibiscus tea?

Hibiscus tea is typically made from dried flowers of the hibiscus plant, also known as hibiscus sabdariffa

Hibiscus plants are native to tropical and subtropical climates, and their trumpet-shaped flowers are used for culinary and medicinal purposes in many parts of the world.  

Hibiscus tea is known for its vibrant red color and refreshing taste. It has long been known to promote cardiovascular health and improve liver function.

Benefits of hibiscus tea for high blood pressure

Regularly drinking hibiscus tea may be particularly beneficial for individuals with hypertension, a cardiovascular disease characterized by elevated blood pressure.

Hibiscus flowers are rich sources of flavonoids and anthocyanins. These potent antioxidants are believed to stimulate the production of nitric oxide, a gaseous compound that helps relax and widen blood vessels.

“Relaxed blood vessels improve blood flow and lower resistance in the arteries,” explains Dr. Berg. “This ultimately lowers blood pressure and promotes cardiovascular health.”

In fact, research published in the Journal of Nutrition found that mildly hypertensive adults who drank eight ounces (240 ml) of hibiscus tea three times per day for six weeks significantly lowered systolic and diastolic blood pressure.  

While further research is needed to confirm its role in cardiovascular health, hibiscus tea may be as effective in lowering blood pressure as conventional antihypertensive drugs, thereby reducing the risk of potential side effects and drug-induced nutrient deficiencies.

Recipe for Hibiscus Tea

Hibiscus tea, also known as sour tea in some regions, is just as easy to brew as other herbal teas. 

Here’s a simple hibiscus tea recipe you can make at home.


1 Tbsp dried hibiscus flowers  

8 oz (240 ml) boiling water 


Add dried hibiscus leaves to a cup or teapot and steep in boiling hot water for five minutes. 

Strain the tea and allow it to cool until it reaches your desired temperature.


You can also opt for an iced tea recipe and chill the hibiscus infusion in the fridge before consuming it throughout the day. 

Hibiscus tea has a naturally tart flavor, and some people prefer to add some cinnamon or vanilla extract to balance its sharpness.

Teabags are a convenient alternative to loose hibiscus leaves, and it’s important to follow the instructions on the product label to achieve the best flavor and optimal potency of hibiscus tea.

How much hibiscus tea should you drink?

Hibiscus tea is naturally caffeine-free, and most people can safely consume several cups daily.

If you want to boost your antioxidant intake and promote general health, it’s generally recommended to drink one to two cups of hibiscus tea per day.

To manage hypertension, it’s best to aim for three cups of hibiscus tea daily. It can take up to two months of regular hibiscus tea consumption to see a reduction in blood pressure.

Potential risks of hibiscus tea

While hibiscus tea offers various health benefits, it’s crucial to be aware of the potential risks associated with its consumption. 

It’s best to avoid hibiscus tea during pregnancy and while trying to conceive. Hibiscus can stimulate uterine blood flow and trigger menstruation, which may increase the risk of miscarriage during the early stages of the first trimester. 

In addition, hibiscus tea can interact with blood pressure medication and lead to dangerously low blood pressure linked to fainting and severe dizziness.

It’s essential to consult a healthcare provider if you are taking antihypertensive drugs and are considering adding hibiscus tea to your daily routine.

Other benefits of hibiscus tea

In addition to its potent blood pressure-lowering properties, hibiscus tea has several other potential health benefits.

Here are four reasons why you should be drinking hibiscus tea regularly.

1. Nutritional powerhouse 

Hibiscus is a rich source of vitamin C, folic acid, calcium, zinc, and various phytochemicals with potent antioxidant properties. 

In fact, research published in The Journal of Dietary Supplements found that hibiscus contains more antioxidants than green tea, which is often hailed as one of the most antioxidant-rich beverages.

Antioxidants protect cells from the adverse effects of free radicals. These harmful metabolic by-products can cause cellular damage and impair normal cell functions, linked to increased risk of inflammation, chronic diseases, and premature aging. 

2. Supports metabolic health and liver function 

Drinking hibiscus tea may lower the risk of obesity and liver steatosis, also known as fatty liver.

It’s believed that flavonoids and polyphenols in hibiscus promote metabolic health by improving blood sugar control and cholesterol balance and boosting the liver’s ability to metabolize fats.

This study published in Food and Function summarizes, “Hibiscus extract reduced obesity, abdominal fat, and improved liver steatosis and could act as an adjuvant for preventing obesity and non-alcoholic fatty liver.” 

3. Natural antibiotic 

Hibiscus tea has traditionally been used as a natural remedy for various digestive and respiratory tract infections.  

Its antimicrobial properties are linked to the high concentrations of antioxidants in hibiscus flowers, which may help eliminate bacteria and fungi by damaging their cellular membranes and causing microbial death. 

Hibiscus has been found beneficial in managing infections caused by E. coli, Salmonella, and Candida, the main culprit for yeast infections and oral thrush.

4. Promotes kidney health 

Hibiscus has mild diuretic properties that stimulate urine production, which can help prevent high oxalate kidney stones by aiding in the removal of oxalates and other waste products from the kidneys.
