Uses and Benefits of Hibiscus sabdariffa

Posted by Emily van Oosterom on

Arguably one of the most delightful and delicious medicinal plants available to us is Hibiscus sabdariffa. Commonly known as Roselle, is a versatile and vibrant plant that is widely used and appreciated due to its unique flavour and health benefits.

Native to West Africa, Roselle has become a staple in various cuisines and traditional medicinal systems, and is as widely used for its vibrant colour and tart flavour as it is for the many medicinal benefits.

Historical and Traditional Uses

Roselle has a long history of use in various traditional medicine systems, particularly in West Africa, the Middle East, and Southeast Asia. Its uses have ranged from treating digestive issues and respiratory infections to managing hypertension and maintaining heart health. In many cultures, Roselle has been consumed as a refreshing beverage to help cool the body and promote hydration.

In addition to its medicinal uses, Roselle has also played a role in culinary applications. The calyces, or the fleshy red sepals enclosing the plant's seedpods, are used to make drinks, jams, and sauces. The leaves are often consumed as a leafy vegetable, while the seeds are used for their oil or as a coffee substitute.

Current Uses

Today, Roselle is commonly used to make herbal teas, juices, and natural food colourings. The dried calyces are used as a popular ingredient in beverages like the Mexican Agua de Jamaica and the West African Bissap.  

Roselle's popularity has also extended to the world of natural health and wellness, with many people consuming it for its antioxidant, anti-inflammatory, and diuretic properties. It's available in various forms, such as tea, powder, and extract, making it easy for individuals to incorporate it into their wellness routines.

Health Benefits and Active Compounds

Roselle is rich in a range of bioactive compounds that contribute to its potential health benefits including anthocyanins, flavonoids, and organic acids. These compounds are believed to possess antioxidant, anti-inflammatory, and diuretic properties, among others.

Some studies have suggested that Roselle may help manage hypertension, as it has been shown to lower blood pressure in some individuals. Additionally, its antioxidant properties may help protect the body against oxidative stress and free radical damage, supporting overall health and well-being.

Precautions and Contraindications

While Roselle is generally considered safe for most individuals, there are some precautions and contraindications to keep in mind:

  1. Pregnancy and breastfeeding: Due to limited research proving it’s safety during these times, those who are pregnant or breastfeeding may wish to avoid its consumption.
  2. Low blood pressure: As Roselle may lower blood pressure, individuals with very low blood pressure or those taking blood pressure medications should consult with a healthcare professional before consuming it.
  3. Diabetes: Roselle may affect blood sugar levels, so individuals with diabetes or those taking medications to manage blood sugar should consult a healthcare professional before using Roselle.


Nutritious Roselle Recipes

To help you incorporate Roselle into your diet, here are some easy recipes:

Roselle Tea

Cultivating Roselle in a Home Garden

Growing Roselle in your home garden can be a rewarding experience, allowing you to enjoy its beautiful flowers and harvest its flavourful calyces. Roselle is a tropical plant and thrives in warm climates, but it can also be grown in cooler regions with some extra care.

To cultivate Roselle in your garden, follow these steps:

  1. Choose a sunny location with well-draining soil. Roselle prefers full sun and will produce the best yield in a spot that receives at least six hours of sunlight per day.
  2. Prepare the soil by adding organic matter, such as compost or aged manure, to improve its fertility and drainage. Roselle prefers slightly acidic to neutral soil with a pH between 6.0 and 7.0.
  3. Sow the seeds directly in the garden after the last frost, or start them indoors 6-8 weeks before the last frost if you live in a cooler climate. Space the seeds about 18-24 inches apart and cover them with 1/4 inch of soil.
  4. Keep the soil consistently moist but not waterlogged. Roselle is moderately drought-tolerant but will produce the best yield with regular watering.
  5. Fertilise the plants with a balanced, slow-release fertiliser or organic compost every 4-6 weeks throughout the growing season.
  6. Prune the plants regularly to encourage branching and bushier growth. Pinch off the growing tips when the plants reach 12-18 inches in height.
  7. Harvest the calyces when they are plump and bright red, typically 3-4 weeks after the flowers bloom. The leaves and young seedpods can also be harvested for consumption.
