Rooibos Tea (Red Bush Tea) – Side Effects & Health Benefits

Rooibos Tea (Red Bush Tea) – Side Effects, Health Benefits (Caffeine-Free, Acne, Hair, Sleep, Acid Reflux & Weight Loss), Taste:

Rooibos tea, also known as red bush tea, is made from the leaves of the Aspalathus Linearis, a plant that grows extensively in the Cederberg Mountains of South Africa.

It is often called “red tea” because of the bright red coloring the leaves take on during the fermentation and oxidation processes. A properly brewed cup of tea will be a rich red color and have a nutty, sweet flavor.

Because it does not derive from the Camellia sinensis plant (like white, black, green, or oolong teas), this tea is considered more of an herbal drink, than a „true” tea.

It has gained appreciation among tea lovers in recent years for its delicious flavor. It’s quite popular in Germany, Japan, Holland, and England.

But it has also gotten a lot of attention from researchers, who have been testing its health-promoting elements, including stomach cramps, headaches, immune system health, allergies, asthma, and aiding with common aches and pains.

The absence of caffeine in red tea makes it a wonderful bedtime drink that can aid those with insomnia and calm an irritated throat.


It has an earthy flavor like yerba mate, and a taste somewhat similar to hibiscus tea. Also, it is less sour than most herbal teas and far less bitter than green or black teas.

Side Effects Of Rooibos Tea (Or Red Bush Tea)

Iron Absorption 

Although it is hard to think that tea may present side effects, the key to all things is moderation.

At the moment, no research is available that focuses on the long-term effects or side effects of red bush tea consumption. There are, however, a few known side effects, like the slow absorption of iron in food.

Because of its low levels of tannin, this tea, much like black tea, makes it difficult for the body to absorb iron in vegetables (not in meat).

Hence, people with iron deficiency are recommended to drink this tea after meals and even consult with their healthcare specialist before including it in their daily diet.

Increased Anxiety And Irritabilityanxiety stress

Daily consumption of this tea is also linked to increased anxiety. Moreover, one may also suffer from a temporary increase, if consumed in excess.

However, the good thing about aspalathus linearis is that the increased irritability and anxiety due to its consumption decreases naturally after a few hours. But one should remain cautious and not go for over-consumption of this tea.

Skin And Breathing Problems 

There are no studies that show these problems, but some people may face any of them. The tea can also cause skin or breathing problems to those allergic or in the case of overdose.

These may present in the form of breathing difficulty, rashes, itchy or swollen skin, shortness of breath, and chest tightness. In case any of these symptoms appear after consuming the tea, a doctor should be consulted immediately.

However, the safety of tea is not regulated. Please always discuss your decision to drink the tea with your doctor or healthcare provider.
