The Health Benefits of African Herbal Teas

While coffee often takes center stage in discussions about African beverages, the continent is also home to a remarkable variety of herbal teas with profound wellness properties. From the red mountains of South Africa to the lush highlands of East Africa, traditional herbal infusions have been used for centuries to promote health, treat ailments, and provide nourishment. In this article, we’ll explore the wellness properties of traditional African herbal teas like Rooibos, Honeybush, and Moringa, examining both their historical uses and the modern scientific research that increasingly validates their health benefits.

Rooibos: South Africa’s Ruby Elixir

Rooibos (Aspalathus linearis), meaning “red bush” in Afrikaans, is perhaps Africa’s most internationally recognized herbal tea. Native exclusively to the Cederberg region of South Africa’s Western Cape Province, this distinctive plant has been harvested and enjoyed by indigenous peoples for generations before gaining global popularity.

Historical and Cultural Significance

The indigenous Khoisan people of South Africa were the first to discover the delicious taste and medicinal properties of rooibos. They would climb the mountains to cut the fine, needle-like leaves of wild rooibos plants, then bruise them with hammers, leave them to ferment in heaps, and dry them in the sun. This traditional processing method is still reflected in the production of what we now call “red” or traditional rooibos.

Dutch settlers in the Cape adopted rooibos as an alternative to expensive black tea imported from Europe. During World War II, when traditional tea supplies were disrupted, rooibos consumption increased dramatically, cementing its place in South African culture.

Today, rooibos remains an integral part of South African identity. It’s common to find South Africans carrying a flask of rooibos wherever they go, and the tea is often used as a base for traditional home remedies.

Nutritional Profile and Bioactive Compounds

Rooibos tea is naturally caffeine-free, making it suitable for children, pregnant women, and those sensitive to stimulants. It contains minimal tannins, which means it lacks the bitter astringency often associated with regular tea and doesn’t inhibit iron absorption to the same degree.

The impressive health benefits of rooibos are largely attributed to its unique polyphenol content, including:

•Aspalathin: A rare antioxidant found almost exclusively in rooibos

•Nothofagin: Another rare antioxidant with potent anti-inflammatory properties

•Quercetin: A flavonoid with antihistamine and anti-inflammatory effects

•Luteolin: A flavonoid with antioxidant and anti-inflammatory properties

Rooibos also contains essential minerals including iron, calcium, potassium, copper, manganese, zinc, and magnesium, though in relatively small amounts.

Evidence-Based Health Benefits

Modern scientific research has begun to validate many of the traditional uses of rooibos, revealing a range of potential health benefits:

Antioxidant Protection

Rooibos tea is rich in antioxidants that help combat oxidative stress—a key factor in aging and many chronic diseases. Research published in the journal Food Chemistry found that the antioxidant activity of rooibos may help protect cells from damage caused by free radicals and environmental toxins.

A study in the Journal of Ethnopharmacology demonstrated that rooibos tea provides significant protection against oxidative damage to the liver, suggesting potential hepatoprotective effects.

Heart Health Support

Several studies have indicated that rooibos may benefit cardiovascular health. Research published in the Journal of Ethnopharmacology found that rooibos tea inhibits angiotensin-converting enzyme (ACE), which causes blood vessels to contract and blood pressure to rise. This ACE-inhibiting effect is similar to how certain blood pressure medications work.

A six-week study published in the Journal of Ethnopharmacology involving 40 participants at high risk for cardiovascular disease found that drinking six cups of rooibos tea daily significantly improved lipid profiles and redox status, potentially reducing cardiovascular risk factors.

Blood Sugar Regulation

The unique antioxidant aspalathin, found almost exclusively in rooibos, has shown promising effects on blood sugar regulation. Animal studies published in Phytomedicine suggest that aspalathin may help balance blood sugar levels and improve insulin resistance, potentially offering benefits for managing or preventing type 2 diabetes.

Digestive Health

Rooibos has traditionally been used to soothe digestive discomfort, including colic in infants. Its antispasmodic effects may help relieve stomach cramps and digestive upset. Research in Basic & Clinical Pharmacology & Toxicology suggests that these traditional uses have scientific merit, as rooibos showed antispasmodic effects on gastrointestinal muscles in laboratory studies.

Skin and Allergy Benefits

The antihistamine and anti-inflammatory properties of rooibos make it potentially beneficial for skin conditions and allergies. Topical applications of rooibos have been studied for treating dermatological issues, and some research suggests it may help soothe eczema and acne when applied directly to the skin.

A Japanese study found that rooibos tea significantly reduced production of the antibody Immunoglobulin E (IgE), which is involved in allergic reactions, suggesting potential benefits for managing allergies.

Traditional vs. Green Rooibos

Traditional rooibos undergoes an oxidation (fermentation) process that gives it its characteristic reddish color and sweet, nutty flavor. However, green (unoxidized) rooibos is also available and contains higher levels of antioxidants, particularly aspalathin, which is partially lost during the oxidation process.

While green rooibos may offer enhanced antioxidant benefits, traditional red rooibos has a more developed, sweeter flavor that many find more palatable. Both varieties offer significant health benefits and can be incorporated into a wellness routine.

Honeybush: Rooibos’s Sweet Cousin

Honeybush (Cyclopia species) is another South African herbal tea that shares many characteristics with its more famous cousin, rooibos. Named for its honey-like scent when the bright yellow flowers are in bloom, honeybush grows naturally in the coastal and mountainous regions of the Western and Eastern Cape provinces.

Historical and Cultural Context

Like rooibos, honeybush has been used by indigenous South Africans for centuries. The Khoisan and later the Cape colonists gathered the plant from the wild for its pleasant taste and medicinal properties. Traditional uses included treating coughs, alleviating menopausal symptoms, and stimulating milk production in nursing mothers.

Commercial cultivation of honeybush began much later than rooibos, with organized farming only developing in the 1990s. Today, several species of Cyclopia are cultivated for tea production, with Cyclopia intermedia, Cyclopia subternata, and Cyclopia genistoides being the most common.

Nutritional Profile and Bioactive Compounds

Honeybush shares many characteristics with rooibos—it’s naturally caffeine-free, low in tannins, and rich in antioxidants. However, its phytochemical profile differs in several important ways:

•Xanthones: Rare antioxidants with anti-inflammatory and anticancer potential

•Isoflavones and coumestans: Phytoestrogens that may help balance hormones

•Mangiferin: A potent antioxidant also found in mangoes

•Hesperidin: A flavanone glycoside with cardiovascular benefits

Honeybush also contains essential minerals and is particularly rich in potassium, calcium, and magnesium.

Evidence-Based Health Benefits

While honeybush has been less extensively studied than rooibos, emerging research suggests several potential health benefits:

Antioxidant and Anti-inflammatory Effects

Research published in the Journal of Agricultural and Food Chemistry has demonstrated the significant antioxidant capacity of honeybush tea. These antioxidants help neutralize free radicals that can damage cells and contribute to chronic diseases and aging.

A study in Food Chemistry found that certain honeybush extracts showed potent anti-inflammatory activity, inhibiting various markers of inflammation in laboratory tests. This suggests potential benefits for inflammatory conditions.

Phytoestrogenic Properties

The isoflavones and coumestans in honeybush act as phytoestrogens—plant compounds that can mimic some of the effects of estrogen in the body. Research in the Journal of Steroid Biochemistry and Molecular Biology suggests these compounds may help alleviate menopausal symptoms and support hormonal balance.

This phytoestrogenic activity may explain the traditional use of honeybush for women’s health issues, including menstrual discomfort and menopausal symptoms.

Respiratory Support

Honeybush has traditionally been used to treat coughs, colds, and other respiratory ailments. Some research suggests that its anti-inflammatory properties may indeed help soothe irritated airways and reduce mucus production, though more clinical studies are needed to confirm these effects.

Blood Sugar Management

Preliminary research suggests that certain compounds in honeybush may help regulate blood sugar levels. A study in Phytomedicine found that honeybush extract improved glucose tolerance and insulin sensitivity in diabetic rats, suggesting potential benefits for blood sugar management.

Flavor Profile and Varieties

Honeybush has a naturally sweet, honey-like flavor with notes of dried fruit and flowers. It lacks the slight astringency sometimes found in rooibos, making it particularly appealing to those who prefer sweeter herbal teas.

Different species of Cyclopia offer subtle variations in flavor:

•Cyclopia intermedia (mountain honeybush) has a deeper, more woody character

•Cyclopia subternata (valley honeybush) offers floral and light fruity notes

•Cyclopia genistoides (coastal honeybush) provides a stronger, more robust flavor

Like rooibos, honeybush can be found in both traditional (fermented) and green (unfermented) varieties, with the green version retaining more antioxidants but offering a less developed flavor profile.

Moringa: The Miracle Tree of East Africa

Moringa oleifera, often called the “miracle tree” or “drumstick tree,” is native to parts of Africa and Asia and has been naturalized in many tropical and subtropical regions. While particularly prominent in East African countries like Kenya, Tanzania, and Ethiopia, moringa has spread throughout the continent due to its remarkable nutritional and medicinal properties.

Historical and Cultural Significance

Moringa has been valued for thousands of years across various cultures. Ancient Egyptians, Greeks, and Romans extracted oil from moringa seeds for perfume and skin protection. In traditional African medicine, different parts of the moringa tree—leaves, pods, seeds, roots, flowers, and bark—have been used to treat various ailments.

In many East African communities, moringa has been a crucial resource during times of food scarcity, providing essential nutrients when other food sources were limited. The tree’s ability to thrive in harsh conditions and its year-round leaf production make it particularly valuable in drought-prone regions.

Nutritional Powerhouse

Moringa leaves, which are typically dried and powdered for tea, are exceptionally nutrient-dense:

•Protein: Contains all nine essential amino acids, rare for a plant source

•Vitamins: Rich in vitamins A, C, E, various B vitamins, and vitamin K

•Minerals: High in calcium, potassium, iron, magnesium, and zinc

•Antioxidants: Contains quercetin, chlorogenic acid, and beta-carotene

Gram for gram, moringa leaves contain:

•7 times the vitamin C of oranges

•4 times the calcium of milk

•4 times the vitamin A of carrots

•3 times the potassium of bananas

•2 times the protein of yogurt

This exceptional nutritional profile has earned moringa the nickname “the most nutritious plant on earth” in some circles.

Evidence-Based Health Benefits

Modern scientific research has begun to validate many traditional uses of moringa, revealing an impressive array of potential health benefits:

Nutritional Support and Malnutrition

Moringa’s dense nutritional profile makes it valuable for addressing malnutrition. A study published in the Journal of the Science of Food and Agriculture found that moringa leaf supplementation significantly improved the nutritional status of malnourished children in Senegal.

Organizations like Trees for Life and the Church World Service have promoted moringa cultivation in developing regions specifically to combat malnutrition, with promising results in multiple African countries.

Antioxidant and Anti-inflammatory Effects

Moringa leaves are rich in antioxidants that help combat oxidative stress and inflammation. Research in the Journal of Food Science found that moringa leaf extract has potent free-radical scavenging activity, comparable to or exceeding many common antioxidant supplements.

A study in Inflammation Research demonstrated that moringa extract significantly reduced inflammatory markers in cells, suggesting potential benefits for inflammatory conditions.

Blood Sugar Regulation

Several studies have indicated that moringa may help regulate blood sugar levels. Research published in the Journal of Diabetes found that moringa leaf powder reduced fasting blood glucose levels in diabetic patients. Another study in the International Journal of Food Sciences and Nutrition showed that adding moringa leaves to a meal reduced the glycemic response in healthy subjects.

The blood sugar-regulating effects are attributed to several compounds, including isothiocyanates and chlorogenic acid, which may help improve cellular sugar uptake and inhibit digestive enzymes that break down carbohydrates.

Cholesterol and Heart Health

Moringa may benefit cardiovascular health by helping to regulate cholesterol levels. A study in the Journal of Ethnopharmacology found that moringa leaf extract reduced cholesterol levels in high-fat diet-fed rats, with effects comparable to the cholesterol-lowering drug simvastatin.

Human studies have shown similar promise. Research published in Frontiers in Pharmacology found that moringa leaf powder supplementation significantly reduced total and LDL (“bad”) cholesterol while increasing HDL (“good”) cholesterol in hyperlipidemic subjects.

Liver Protection

Moringa appears to have hepatoprotective properties, helping to protect the liver from damage. Research in the Journal of Medicinal Food demonstrated that moringa extract protected against liver damage induced by anti-tubercular drugs, suggesting potential benefits for liver health.

The liver-protective effects are attributed to the high concentration of polyphenols and other antioxidants that help reduce oxidative damage to liver cells.

Traditional Preparation and Modern Uses

In traditional African settings, moringa tea is prepared by steeping dried leaves in hot water. The resulting infusion has a mild, slightly earthy flavor that some compare to matcha or spinach. Often, it’s combined with honey, lemon, or ginger to enhance the taste.

Modern preparations include:

•Pure moringa tea bags for convenience

•Moringa powder that can be stirred into hot water

•Moringa blends with other herbs or tea leaves

•Moringa supplements in capsule form

For those new to moringa, starting with a blend or adding honey can make the earthy flavor more approachable.

Other Notable African Herbal Teas

Beyond the three major herbal teas discussed above, Africa offers a wealth of other traditional infusions with significant health benefits:

Buchu (Agathosma betulina)

Native to the Western Cape of South Africa, buchu has been used by indigenous San and Khoi peoples for centuries. Traditionally, it was used as a general health tonic and specifically for urinary tract and kidney issues.

Modern research has confirmed buchu’s diuretic and anti-inflammatory properties, making it potentially beneficial for urinary tract infections and prostate health. It contains diosphenol and other volatile oils that have antimicrobial effects against common urinary pathogens.

Buchu tea has a strong, minty-blackcurrant flavor and is often blended with other herbs to make it more palatable.

Bissap (Hibiscus sabdariffa)

Known as bissap in Senegal and other West African countries, hibiscus tea is made from the dried calyces of the hibiscus flower. This vibrant red infusion is consumed throughout Africa, from Egypt (where it’s called karkade) to Senegal, Mali, and beyond.

Hibiscus tea is rich in anthocyanins, which give it its characteristic red color and potent antioxidant properties. Research has shown that regular consumption may help lower blood pressure and improve lipid profiles. A study published in the Journal of Nutrition found that drinking three cups of hibiscus tea daily for six weeks reduced systolic blood pressure in pre-hypertensive and mildly hypertensive adults.

The tart, cranberry-like flavor of hibiscus makes it refreshing both hot and cold, and it’s often sweetened with honey or sugar.

Lemon Bush (Lippia javanica)

Also known as fever tea or lemon bush, this aromatic plant is native to central and southern Africa. It has been used traditionally to treat fever, coughs, colds, and malaria.

Research has confirmed the antimicrobial and antipyretic (fever-reducing) properties of lemon bush. A study in the Journal of Ethnopharmacology found that extracts showed significant activity against several bacterial strains.

As the name suggests, lemon bush tea has a pleasant citrusy flavor with herbal undertones, making it enjoyable without additives.

Wild Dagga (Leonotis leonurus)

Wild dagga, also called lion’s tail, is native to southern Africa and has been used in traditional medicine by various indigenous groups, including the Hottentots and Zulu. Despite its name (dagga is a local term for cannabis), it is not related to marijuana but does have mild psychoactive properties in concentrated forms.

As a tea, wild dagga is much milder and has been used traditionally for treating fever, headaches, and respiratory conditions. Research has identified marrubiin as one of its active compounds, which has bronchodilatory effects that may help with asthma and other respiratory conditions.

The tea has a somewhat bitter, earthy flavor and is often mixed with honey or other herbs.

Brewing Tips for Maximum Health Benefits

To get the most out of African herbal teas, proper preparation is key:

Water Temperature and Steeping Time

Unlike true tea (Camellia sinensis), which can become bitter when over-steeped, most African herbal teas benefit from longer steeping times to fully extract their beneficial compounds:

•Rooibos and Honeybush: Use boiling water (212°F/100°C) and steep for 5-7 minutes. These teas don’t become bitter with extended steeping, so you can even leave the leaves in while drinking.

•Moringa: Use water that’s slightly below boiling (195-205°F/90-96°C) and steep for 3-5 minutes. Higher temperatures can degrade some of the heat-sensitive vitamins.

•Hibiscus: Use boiling water and steep for 5-7 minutes. Longer steeping will produce a stronger, more tart flavor and deeper red color.

Quality Matters

The quality of herbal tea significantly affects both its flavor and health benefits:

•Look for organic certification when possible, as this ensures the plants were grown without synthetic pesticides or fertilizers.

•For rooibos and honeybush, products from South Africa are generally of higher quality than those grown elsewhere, as these plants are indigenous to specific South African regions.

•With moringa, leaf color is a good indicator of quality—the powder or dried leaves should be vibrant green, not dull or brownish.

•Whole leaf or cut leaf products generally retain more beneficial compounds than finely powdered tea bags (with the exception of moringa, which is typically consumed as a powder).

Enhancing Absorption and Flavor

Certain additions can enhance both the flavor and the bioavailability of beneficial compounds in African herbal teas:

•Adding a squeeze of lemon or a small amount of vitamin C-rich fruit can improve the absorption of iron from rooibos tea.

•A small amount of fat, such as a teaspoon of coconut oil or a splash of milk, can enhance the absorption of fat-soluble vitamins and antioxidants in moringa tea.

•Raw honey not only sweetens but adds its own antimicrobial and antioxidant properties to complement the tea’s benefits.

•Warming spices like cinnamon, ginger, or cardamom pair well with African herbal teas and add their own health benefits.

Supporting African Producers

Many African herbal teas, particularly rooibos and honeybush, support rural economies in their regions of origin. By purchasing fair trade certified products, consumers can help ensure that farmers receive fair compensation for their work.

Organizations like the South African Rooibos Council have worked to secure geographic indication protection for rooibos, ensuring that the name can only be used for tea produced in specific regions of South Africa. This helps protect the livelihoods of local farmers and the authenticity of the product.

Environmental Considerations

Wild harvesting of plants like honeybush has raised sustainability concerns as demand increases. Supporting certified sustainable or cultivated sources helps protect wild populations.

Climate change poses significant challenges for many African herbal tea producers. Rooibos, in particular, grows in a very specific climate zone that is threatened by rising temperatures and changing rainfall patterns. Supporting climate-resilient agricultural practices through conscious purchasing decisions can help address these challenges.

Cultural Appreciation vs. Appropriation

As we embrace traditional African herbal teas, it’s important to acknowledge their cultural origins and the indigenous knowledge systems that discovered and developed their uses. Supporting companies that acknowledge these origins and give back to source communities helps ensure that the benefits of these traditional products flow back to their places of origin.
