Rooibos: South Africa’s Remarkable Red Bush

There are some plants that simply belong to a place. Rooibos is one of them.

Rooibos (Aspalathus linearis) is indigenous to the Cederberg region of South Africa’s Western Cape, roughly 200 kilometers north of Cape Town. Remarkably, this is the only region in the world where rooibos grows naturally.

Born in the Cederberg

The rugged Cederberg landscape may seem an unlikely place for something so delicate to flourish. Summers are hot and dry, winter brings much of the region’s rainfall, and the soil is coarse, sandy and relatively low in nutrients.

But rooibos is beautifully adapted to these conditions.

The region has a Mediterranean-type climate, with hot, dry summers and cooler, wetter winters. Rooibos has adapted to the deep sandy soils and challenging conditions of this unique landscape.

It is truly a plant shaped by its place.

Why Is It Called Rooibos?

The Afrikaans word rooibos means “red bush.”

Interestingly, the plant begins green. What creates the familiar reddish-brown rooibos we know and love is oxidation.

After harvesting, the leaves and stems are cut and bruised and allowed to oxidize. During this process, they develop their characteristic deep amber-red color, aroma and naturally smooth flavor.

Red Rooibos and Green Rooibos

Both red and green rooibos come from the same plant. The difference is what happens after harvesting.

Traditional red rooibos is oxidized before it is dried, producing its distinctive reddish color and rich, naturally mellow flavor.

Green rooibos is dried soon after harvesting to limit oxidation. It produces a lighter-colored infusion with a fresher, more delicate flavor. Because it undergoes less oxidation, green rooibos generally retains higher concentrations of certain antioxidants.

What Makes Rooibos So Special?

Rooibos is naturally caffeine-free and contains an array of plant polyphenols and antioxidants, including a distinctive antioxidant called aspalathin.

Interest in the potential health benefits of rooibos has grown considerably. In 2022, South Africa’s Department of Science and Innovation invested R4.8 million in rooibos research. The South African Rooibos Council matched the investment, bringing the combined research funding to nearly R10 million.

Scientists continue to investigate the relationship between rooibos and human health.

Potential Health Benefits of Rooibos

Rooibos is particularly valued for its antioxidant compounds, which may help the body defend against oxidative stress.

Research has explored rooibos in several areas of health and wellness, including:

* Antioxidant protection and the body’s response to oxidative stress

* Heart health, including cholesterol and other cardiovascular markers

* Healthy glucose metabolism and blood sugar regulation

* Inflammation and the body’s inflammatory response

* Metabolic health

* Bone health, an emerging area of scientific interest

Research into many of these potential benefits is ongoing, and rooibos should not be considered a treatment or cure for any medical condition.

Naturally Occurring Minerals

Rooibos also contains naturally occurring minerals and trace elements, including potassium, calcium, magnesium, iron, manganese, zinc and copper.

Although these minerals are present, a cup of rooibos generally provides relatively small amounts compared with our daily nutritional requirements. Rooibos is therefore best enjoyed as part of an overall healthy lifestyle rather than as a primary source of dietary minerals.

What About Bone Health?

Bone health is an especially interesting area of emerging rooibos research.

Rooibos contains polyphenols and naturally occurring minerals associated with normal physiological processes involving bone. Early laboratory research has generated interest in the possible relationship between rooibos compounds and bone health.

However, there is not yet sufficient human clinical evidence to say that drinking rooibos prevents osteoporosis or increases bone density. It remains a promising area for continued scientific investigation.

A Naturally Caffeine-Free Cup

One of the wonderful things about rooibos is that it is naturally caffeine-free.

That makes it a beautiful choice throughout the day—from the first cup in the morning to a soothing cup as part of an evening ritual. Its naturally smooth character also means that many people enjoy it without milk or sweeteners.

Hot or iced, red or green, rooibos offers a distinctive taste of South Africa.

From South Africa to Your Cup

Perhaps that is what makes rooibos so extraordinary.

A plant that grows naturally in one small region of the world—adapted to hot summers, winter rains, sandy soil and the rugged landscape of South Africa’s Cederberg—has found its way into teacups around the globe.

Rooibos is more than a beautiful cup of tea. It is a taste of South Africa, a story of place and tradition, and today, the subject of a growing body of scientific research.

At Desert Sage, we believe every cup has a story.

Rooibos has one of the most remarkable stories of all.
