An herbal tea from South Africa, rooibos is a delicious, caffeine-free way to upgrade your tea habit. While other teas have an acquired taste, rooibos tea has a sweet, mild flavor profile with notes of honey and vanilla. The red beverage is one of the most palate-pleasing types of tea. In addition to the flavor, the tea is packed with health benefits that will earn it a space in your morning (or evening) routine.

What is rooibos tea and what does it taste like?

Loose rooibos tea leaves

Rooibos tea comes from the shrub aspalathus linearis, and isn’t actually a true tea — it’s an herb with long, needle-like leaves. When it is harvested and dried, rooibos is brewed into a reddish-brown, caffeine-free, herbal infusion also known as African red tea or red bush tea. The plant is cut by hand and then bruised to encourage oxidation, which generates the rich color and flavor. As it oxidizes, rooibos becomes redder and sweeter.

It has a mild, aromatic taste that is sweet and fruity with hints of vanilla and honey. You can drink it just as you would black or green tea — plain, with lemon and sweetener, as a creamy latte or with butter as a caffeine-free substitute for Bulletproof Coffee.

In the late 1990s, tea distributors began offering green rooibos tea, a less oxidized type of rooibos. This green version has double the number of antioxidants than red rooibos and offers a more mineral, grassy flavor.[3]

The benefits of rooibos tea

Cup of rooibos tea

Boosts antioxidant levels in the body

Rooibos gives you a delicious dose of antioxidants. Antioxidants clean up the harmful free radicals that can damage cells.

Research shows that drinking rooibos tea helps regulate glutathione metabolism in the body.[4]The most prevalent antioxidant in the body and certainly one of the most powerful, glutathione has been shown to protect against toxins, free radicals and pathogens. Think of it as your body’s own natural detoxifier..[5]

Aspalathin — found only in rooibos tea — and nothofagin are two powerful antioxidants that have been shown to have beneficial properties.[6][7]

May improve blood pressure and circulation

Rooibos may provide some cardio protection.[8] A study involving 17 healthy volunteers took a look at the effects that different teas had on angiotensin-converting enzyme (ACE), an enzyme located in the inner layer of blood vessels that causes blood vessels to shrink, thus increasing blood pressure. The study found that one hour after people drank 13.5 ounces of rooibos tea, ACE levels went down, lowering participants’ blood pressure.[9]

Promotes healthy cholesterol

Another study over a six-week period showed that drinking six cups of rooibos tea daily significantly increased levels of polyphenols. These are plant compounds with vital antioxidant properties which increase HDL cholesterol. HDL cholesterol repairs the walls of your blood vessels and acts as a scavenger. It collects idle or unused LDL cholesterol in your bloodstream and routes it back to your liver for dispatch. This study showed participants’ LDL markers went down, potentially because the HDL was doing such a great job.[10]

Aids in weight management

Low calorie and naturally sweet, rooibos tea can be a great addition to your beverage choices while trying to lose weight.

Research suggests that aspalathin, an active ingredient in rooibos tea, helps reduce stress hormones that trigger hunger and fat storage. Data from this study showed that rooibos tea has the potential for preventing obesity by affecting the balance of energy and how it’s used as energy or stored as fat.[11]

To get the most out of aspalathin, choose green rooibos over red.[12]

Aids digestion

In a study using rabbits and mice, results showed that rooibos tea benefits the digestive system by reducing loose stools, calming muscle spasms in the stomach and decreasing gastric secretions. The presence of flavonoids such as quercetin, luteolin and others are thought to be the reasons for the beneficial effects on the GI system.[13]

Calms colicky babies

In 1968, Annetjie Theron was a South African mother who was struggling with a colicky infant. She discovered that a rooibos tea infusion calmed her baby of chronic colic and allergies. She studied the benefits of rooibos tea and eventually went on to create her own products using Rooibos extract.[14]

May support bone health

The variety of polyphenols in rooibos tea has been shown to improve osteoblast activity (aka cells that develop bones).[15]

The flavonoids orientin and luteolin were specifically studied on bone cells and showed an increased level of bone growth and mitochondrial activity. These flavonoids enhanced the mineral content of the bone cells used in the study, suggesting that rooibos tea had an overall improvement in bone growth.[16]

Rooibos tea side effects

Rooibos has multiple benefits, but as with anything you add to your diet, some people can experience side effects. Be mindful of how you feel after adding rooibos to your diet. If you’re concerned, consult your healthcare provider before using rooibos regularly.
