Hibiscus Tea: Uses, Benefits, Side Effects By Dr. Smita Barode

By Dr Smita Barode +2 more

Introduction

Ruby red-coloured hibiscus tea is often consumed as an alternative to regular tea and coffee. It is refreshing and has a tangy flavour. Hibiscus is found in several warm countries like India, Thailand, Vietnam, Mexico, Saudi Arabia, Malaysia, Sudan, Egypt, Philippines, and Indonesia. The scientific name of the hibiscus is Hibiscus sabdariffa, and it belongs to the family Malvaceae. Hibiscus is commonly known as ‘roselle’ or ‘red sorrel.’ The fleshy red calyx of hibiscus is often used to make hibiscus tea. Hibiscus is a caffeine-free herbal tea that tastes like berries1. Let us look at some hibiscus tea health benefits.

  • Water: 99.6 g
  • Iron: 0.08 mg
  • Potassium: 20 mg
  • Calcium: 8 mg
  • Phosphorous: 1 mg

  • Vitamin B9 (folate): 1 µg
  • Choline: 0.4 mg

Furthermore, hibiscus has several bioactive compounds like anthocyanin, organic acids, triterpenoids, flavonoids, alkaloids, steroids, carotene, and many more1

Properties of Hibiscus Tea

Several studies have shown that hibiscus tea properties may be as follows1:  

  • It may lower cholesterol levels 
  • It may lower blood pressure  
  • It may lower blood sugar levels  
  • It may act as an antimicrobial agent 
  • It may be an antioxidant  
  • It may help to manage weight  
  • It may act as an anti-cancer agent 
  • It may reduce inflammation  

Potential Uses of Hibiscus Tea for Overall Health

Some of the potential hibiscus tea uses are: 

1. Potential Use of Hibiscus Tea for Lowering Blood Sugar Levels 

A study3  by Jamrozik et al. in 2022 showed that the polyphenols in hibiscus tea might lower blood sugar levels by inhibiting enzymes like α-glucosidase and α-amylase. These enzymes are responsible for digesting carbohydrates and increasing glucose levels after consuming food.However, further studies on humans are required to check if hibiscus tea may help to lower blood sugar levels. Therefore, you must check your blood sugar levels regularly and immediately consult the doctor in case of abnormal sugar levels. 

2. Potential Use of Hibiscus Tea for Lowering Blood Pressure 

A study4 by McKay et al. in 2009 showed that flavonoids like delphinidin-3-sambubioside and cyanidin-3-sambubioside present in hibiscus tea might reduce blood pressure. Hibiscus is a vasorelaxant as it relaxes the tension on the walls of blood vessels; therefore, it may lower blood pressure. However, more studies on humans are required to check if hibiscus tea may lower blood pressure. Therefore, you must check your blood pressure and consult your doctor in case of abnormal blood pressure. 

3. Potential Use of Hibiscus Tea for Lowering Cholesterol 

A study5 by Sanadheera et al. in 2021 showed that hibiscus tea might reduce bad cholesterol levels (total cholesterol, low-density lipoprotein, and very low-density lipoprotein). Additionally, it may elevate good cholesterol levels (high-density lipoprotein). This may be due to the antioxidant properties of hibiscus tea. However, more studies on humans are yet to be done to check if hibiscus tea may affect cholesterol levels. Therefore, you must check your cholesterol levels and consult your doctor if you have abnormal cholesterol levels. 

4. Potential Use of Hibiscus Tea for Reducing Inflammation 

A study6 by Raduan et al. in 2013 showed that saponins, flavonoids, and plant sterols might reduce inflammation. Hibiscus tea may inhibit cyclooxygenase. Cyclooxygenase is an enzyme that elevates the levels of prostaglandins (lipids responsible for inflammation). However, more studies on humans are yet to be done to check if hibiscus tea may reduce inflammation. You must consult your doctor if you suspect inflammation in your body. 

5. Potential Use of Hibiscus Tea for Weight Management 

A study7 by F.J. Alarcon-Aguilar et al. in 2007 on mice showed that anthocyanin, cyanidin, and delphinidin in hibiscus tea might reduce weight. Hibiscus tea may reduce weight by reducing the levels of cholesterol and by inhibiting the gastric and pancreatic lipases responsible for increasing the fat levels in the body.7 However, this is the result of animal studies; more studies on humans are required. You must consult your dietitian before making any essential changes to your diet. 

6. Potential Use of Hibiscus Tea for Microbial Infections 

A study10 showed that hibiscus tea might possess antibacterial and antifungal activity. Hibiscus tea may possess activity against Streptococcus mutans, a bacterium from the oral cavity, Schistosoma mansoni, and Campylobacter species. In addition, hibiscus tea may reduce the formation of aflatoxin, a toxin produced by fungi. However, more studies on humans are required to check if hibiscus tea may be beneficial for microbial infections. Therefore, you must consult your doctor if you suspect a microbial infection. 

7. Potential Use of Hibiscus Tea for Cancer 

A study8 by Lin et al. in 2011 showed that hibiscus tea might act against cancer. The polyphenols, like catechin, may be an antioxidants and act against free radicals. Additionally, the polyphenols may inhibit prostate tumours and deactivate the cancerous cells. However, more studies on humans are required to check the anti-cancer effect of hibiscus tea. Therefore, you must immediately consult your doctor if you suspect it instead of self-medicating. 

Though studies show the benefits of hibiscus tea in various conditions, these are insufficient, and further studies are to establish the true extent of the benefits of hibiscus tea on human health. 

How to Use Hibiscus Tea

Here’s a quick and easy hibiscus tea recipe to follow:

  • To prepare hibiscus tea, collect the flowers, wash them thoroughly, and dry them. 
  • Then, peel off the calyx (the whorl that encloses the petals) and store them in an air-tight container. 
  • Take some dried calyx and crush it with a wooden roller. Keep some water for boiling and pour it into a mug. 
  • Put the dry calyx in a net or a tea bag and steep in the water for a few minutes. 
  • You can enjoy the benefits of drinking hibiscus tea by either adding sugar or lemon to enhance the flavour1 

You must visit a doctor before taking hibiscus tea in large quantities or any herbal products. Do not discontinue or replace an ongoing treatment of modern medicine or herbal preparation without consulting a doctor.
