Understanding Rooibos Tea
Don’t know much about rooibos tea? Understanding where it comes from and what it’s made of will help you learn why it’s a must-have.
What is Aspalathus linearis?
Originating from South Africa, rooibos (also called redbush tea in South Africa or Aspalathus linearis) is a herbal tea made from the leaves of the Aspalathus linearis plant. It’s slightly nutty, earthy, naturally sweet, and packed with antioxidant properties—basically, it’s the perfect alternative to your usual cup of green tea, black tea, or coffee.
South African rooibos tea has historically been used for its healing benefits and health properties. It’s versatile, so you can enjoy it solo or blend it with your favorite flavors.
Types of Rooibos Tea
There are several types of rooibos teas available to choose from, including:
Red rooibos: Traditional red rooibos tea undergoes fermentation (harvested leaves are bruised and oxidized naturally), resulting in a tea that’s reddish-brown in color and a robust, full-bodied flavor with a hint of sweetness, earthiness, nuttiness, and caramel aroma.
Green rooibos: Green rooibos teas skip the fermentation process, which preserves its delicate flavor and natural green color. This form of rooibos tea offers a refreshing, crisp, lighter, slightly sweeter flavor with grassy notes and an herbal aroma.
Rooibos flavor blends: Flavored rooibos tea blends contain green or traditional red rooibos as a base and flavors added during processing. Examples of flavor add-ins include:
- Herbs and spices (peppercorns, cloves, cinnamon, cardamom, ginger, and more)
- Oranges, berries, or other fruits
- Peppermint
- Vanilla extract
- Milk
- 100% juice
- Chamomile
- Honey
- Maple syrup
- Rose petals or other flowers
- Hibiscus or other teas
Caramel, chocolate, or other sweet flavorings can enhance the tea’s natural taste and aroma.
Health Benefits of Red Bush Tea
Many studies have examined the beneficial health effects of consuming rooibos teas on a regular basis. Examples include:
Antioxidant and Nutritional Properties
Rooibos teas promote antioxidative status, supporting protection against inflammation and free radical damage. The key nutrients present in 1 cup of brewed rooibos tea includes:
- Calories: 2
- Protein: 0 grams
- Fat: 0 grams
- Carbohydrates: 0.5 grams
- Calcium: 5 milligrams
- Iron: 0.2 milligrams
- Magnesium: 2.4 milligrams
- Potassium: 22 milligrams
- Thiamin: 0.02 milligrams
- Riboflavin: 0.01 milligrams
- Folate: 2.4 micrograms
Examples of the antioxidants present in this tea include aspalathin, nothofagin, flavonoids, and dihydrochalcone glucoside, which enhance antioxidant status and support optimal cellular function.
Caffeine-Free Alternative
Rooibos tea is a caffeine-free alternative to green and black teas, which is beneficial for individuals who are sensitive to this stimulant. Choosing caffeine-free beverages vs. caffeinated drinks can also help enhance sleep quality, sleep duration, and relaxation.
However, being caffeine-free doesn’t mean that rooibos teas are less stimulating. While more clinical studies are needed in this realm, rodent studies suggest that fermented rooibos herbal teas help improve cognitive performance.
Potential Medicinal Uses
Rooibos has the potential for use as a medicinal food based on recent studies. Researchers suggest that rooibos tea may provide the following health benefits:
- Healthier inflammatory response
- Less oxidative stress
- Enhance lipid profiles
- Boosted antioxidant status
- Enhanced blood sugar control
- Optimal skin health
- Heart-healthy benefits
- Enhanced bone, liver, respiratory, and cognitive health
- Neuroprotection against Alzheimer’s disease risk factors
- Healthy weight management support
One review analyzed 18 publications, half of which were conducted in South Africa. Study subjects experiencing optimal health perks consumed between 0.8 and 5 cups (200-1,200 milliliters) of rooibos tea.
Managing inflammation risks means rooibos teas have the potential to support heart health, reduce allergy symptoms, and enhance cellular function while lessening the risk of cellular damage.
While more research is needed, rooibos teas may support healthy skin, diminishing the risk of eczema flare-ups, acne, and wrinkles.
Preparing and Enjoying Rooibos Tea
Some of the many ways to add rooibos tea to your lifestyle and reap its numerous health benefits include:
Brewing Techniques
Prepare a traditional rooibos tea brewing recipe by boiling 8 ounces of water and pouring it over 1 tablespoon of rooibos tea leaves. Let the mixture steep for 5-10 minutes, and enjoy! Some studies show that steeping for 10 minutes or longer creates the ideal cup of rooibos tea.
You might also use tea bags instead, drink the tea cold over ice, or add your favorite flavorings to enhance the flavor of Aspalathus linearis.
Culinary Uses
Consider the following recipes containing rooibos tea:
Drink Aspalathus linearis tea hot, over ice, with extra flavorings, or mixed in with fruit or protein smoothies.
Comparing Rooibos to Other Teas
Rooibos is similar in composition and health benefits to both green and black teas.
Rooibos vs. Green Tea
Rooibos and green teas are both low in calories and packed with antioxidants, though green tea is often characterized by its high content of catechins.
Unlike rooibos and other herbal teas, green tea is also a source of caffeine (containing 29 milligrams per cup), which is why some people prefer green or black teas over herbal varieties. Green tea has a grassy, sharper flavor while rooibos is naturally sweet and softer.
Green tea is known for its effects on weight management due to its catechin and caffeine content, though both rooibos and green teas support a healthy weight, reduced oxidative stress, and protection against neurodegenerative disease and other chronic diseases.
Rooibos vs. Black Tea
The main difference between rooibos and black teas are their flavors and caffeine content. Rooibos tea contains no caffeine, while brewed black teas provide 48 milligrams of caffeine per cup.
Black tea is a rich source of health-promoting polyphenols called theaflavins, which most other teas do not possess. Like green teas, black teas contain catechins, while rooibos teas do not.
Aspalathus linearis teas are typically sweeter and lighter in flavor than black teas, which have more of a bold, slightly malty, full-bodied flavor and strong aroma.
Benefits of Rooibos, Green, and Black Teas
All three of the teas (green, black, and rooibos) contain the cellular health-supporting antioxidant quercetin and an array of other antioxidants, offering protection against cell damage, allergy symptoms, inflammation, heart problems, and other chronic conditions.
Research suggests that all three of these teas support optimal bone health by enhancing osteoblast activity.
Lastly, green, black, and rooibos teas are low in calories—enhancing healthy weight management. Studies show that higher intakes of hot tea consumption were associated with less obesity, smaller waist circumferences, and reduced body mass indexes (BMIs), heart disease risk factors, and inflammation.
Sustainability and Ethical Considerations
Sustainability and ethical considerations pertaining to Aspalathus linearis teas are important to remember.
Environmental Impact of Rooibos Farming
The environment impacts the sustainability of rooibos farming practices. Disabled ecosystems (often due to human impacts), such as climate warming, extreme weather, infectious diseases, water scarcity, and loss of biodiversity, are all concerns for rooibos farmers because of the direct climate and weather influences. The production of sustainably sourced Aspalathus linearis is critical.
Supporting Local Communities
Purchasing rooibos teas grown by South African farmers offers economic benefits for individuals living in this community. Fairtrade and ethical sourcing are vital to the success of Aspalathus linearis’s sustainability, production, and quality.
Collective efforts by businesses, policymakers, nonprofit organizations, development organizations, and rooibos industry producers are essential to mitigate and address environmental and sustainability concerns and facilitate necessary farming practice adaptations.
Implementing certification and quality assurance systems by farmers in South Africa and other areas of production are highly beneficial to ensure top-quality teas. Choose products that have been third-party tested for contaminants and toxins.
