Rooibos tea has been a popular herbal tea in South Africa for centuries. It’s also recently gaining popularity among tea drinkers worldwide for being a palatable alternative to green and black tea, which has a bitter taste. Another sought-after characteristic of rooibos tea is its ample antioxidants, which gives it its valuable health benefits.

What Is Rooibos Tea?

Rooibos tea, also known as red tea or red bush tea, is an herbal tea that’s derived from the Aspalathus linearis plant, a bush native to the mountainous region of Cederberg in South Africa.

The methods used to make organic rooibos tea today are still relatively similar to the processes used more than a hundred years ago. Only the young branches of the Aspalathus linearis plant are used to make the tea. After being harvested, the stems and leaves are then bruised and left to ferment and oxidize.1

The oxidation and fermentation processes give rooibos its distinct reddish brown color, hence the name “red tea.” You should keep in mind, though, that there are other types of tea that are called red tea as well, even though they’re entirely different from rooibos. This includes black tea and hibiscus tea.2,3

This tea comes in an unfermented variant, which is characterized by its green color and grassy taste. Green rooibos is usually more expensive than the traditional red ones, since it contains higher amounts of antioxidants. Rooibos tea also contains other valuable nutrients, which may contribute to its wide array of health benefits.4

Get to Know the Many Health Benefits of Rooibos Tea

Traditionally used to treat different kinds of ailments, the healing properties of rooibos tea have been a subject of numerous studies over the past years. Result shows that its high antioxidant content, together with certain minerals, may help provide numerous health benefits, which include:5

Protects cells against free radicals

Rooibos contains aspalathin and quercetin, which are powerful antioxidants that can help protect the cells against damage caused by free radicals.

Reduces the risk of cancer

Studies have shown that the antioxidants found in rooibos tea, particularly quercetin and luteolin, can help reduce your risk of cancer by killing cancer cells and inhibiting tumor growth.

Improves heart health

According to studies, rooibos tea may help improve heart health by inhibiting the angiotensin-converting enzyme. This enzyme causes blood vessels to contract, indirectly increasing blood pressure levels.

Rooibos tea may also help reduce the bad cholesterol in your body, which may further decrease your chances of developing heart diseases.

Regulates blood glucose levels

The aspalathin found in rooibos tea has an anti-diabetic effect, which may help lower blood sugar levels and reduce the risk for Type 2 diabetes.

Promotes healthy skin and hair

Since rooibos is rich in antioxidants, it can help protect the skin and hair against the negative effects of free radicals.

It also contains alpha hydroxy acid, which is found to be helpful in alleviating skin conditions.6

Maintains healthy brain function

Research shows that regular intake of rooibos tea may help protect the brain against lipid peroxides, ultimately delaying brain aging and preventing deteriorating brain disorders like Alzheimer’s disease.7

In addition to the health benefits mentioned above, rooibos tea is believed to be helpful in enhancing bone health, reducing digestive problems, improving sleep, and alleviating allergies and headaches. Currently, only anecdotal reports are available to support these benefits, so further research is still needed to confirm them.

Rooibos Tea Nutrition Facts

Rooibos is clearly on a par with other types of tea when it comes to antioxidants. What makes it even better is that it has lower levels of tannins, which are linked to poor absorption of certain nutrients. It also does not contain oxalic acid, which is a compound that can increase the risk of kidney stones.8 To view the nutritional facts of rooibos tea, take a look at the chart below:9

Caffeine Content of Rooibos Tea

Even though caffeine is a natural stimulant that may provide positive effects to the body, it can cause palpitations, increased anxiety and other undesirable effects if consumed in high amounts. This is exactly why some tea drinkers are in the search for a type of tea that doe s not contain caffeine. So the question is, does rooibos tea have caffeine?

The answer is that rooibos tea is naturally caffeine-free, which makes it an excellent alternative to green tea and black tea. People who are suffering from sleeping problems can safely drink this tea before bedtime without sacrificing their good night’s sleep. You can also consume this tea without the risk of developing caffeine addiction, which is actually quite common and may lead to withdrawal symptoms such as headache, fatigue and decreased alertness.

How to Make a Good Cup of Rooibos Tea

The brewing process for rooibos is relatively similar to that of other teas. The only difference is that it may require different steeping time and temperature. Here’s a guide on how to brew a good cup of rooibos tea on your own:10,11,12

Use boiling water: Steeping rooibos tea in boiling water makes for a better taste. Make sure that you keep the water hot the entire steeping time. You can do this by placing the cup of tea near a hot surface, like the stove or burner that you just used.

Allow it to steep longer: Rooibos tea requires a longer steeping time than other types of tea, so it’s best to steep it for at least five minutes. Studies suggest that steeping it longer may increase the amount of antioxidants that are imparted to the liquid, making your cup of tea healthier.13

Adjust the serving of tea according to your preference: It’s generally recommended to add 1 teaspoon of rooibos tea per 8 ounces of water. However, this serving is not set in stone, and you may adjust the amount according to your taste.

Although rooibos is already semi-sweet, some people still prefer to serve it with milk and sugar. I suggest that you leave out these ingredients, especially sugar, if you’re after the health benefits of rooibos tea.

How You Should Store Rooibos Tea

Just like other types of tea, rooibos must also be handled and stored properly to retain its flavor and nutrients. Store it in a clean, dry area that’s not exposed to sunlight.15 It’s best to keep it away from other foods with strong odor, such as coffee and spices. You should also put it in an opaque, airtight container to keep it from absorbing odor and moisture from the air. Avoid using plastic containers, as they can transfer chemicals and odors into the tea. Use glass, tin or aluminum containers instead.16

Possible Rooibos Tea Side Effects and Interactions That You Should be Aware of

While rooibos tea is generally very safe to drink, since it has low levels of tannins and is free of caffeine and oxalic acid, there are still a few reported cases wherein it caused several undesirable effects, which include:17,18

Increased liver enzymes: According to a case study, consuming high amounts of rooibos tea daily may increase liver enzymes, which can lead to liver problems. If you have a form of liver disorder, talk to your doctor first before drinking rooibos tea.

Estrogenic activity: The compounds in rooibos tea may stimulate estrogenic activity, so it’s not recommended for people who are at a higher risk of developing hormone-sensitive cancer, such as breast cancer.

There is not enough evidence to determine if rooibos tea is safe for pregnant and breastfeeding women. Remember that it’s always better to be on the safe side, so if you have any doubts regarding the safety of this tea, consult your doctor first before drinking it to avoid any adverse effects.19,20

Choose and Prepare Your Rooibos Tea Properly to Prevent Bacterial Infection

According to a study published in the Journal of the Science and Food Agriculture in 2014, the processing methods of rooibos tea may predispose it to salmonella contamination.21 Salmonella is one of the leading culprits behind foodborne illnesses, and it may even cause death in extreme cases.22

Currently, ozone treatment and salmonella-specific bacteriophages are being used to control salmonella contamination in rooibos tea. If you’re planning to include this tea into your diet, make sure that you purchase it from manufacturers that use these preventive methods to ensure your safety.

You can also prevent falling victim to the life-threatening health issues caused by salmonella by following the proper boiling instructions for rooibos tea. Always use boiling water to kill any harmful microorganisms in the tea.23
