Rooibos (pronounced ROY-boss) tea is a red herbal tea that comes from the fermented leaves of the Aspalathus linearis shrub, a plant native to South Africa.
Many people enjoy it as an alternative to green or black tea. Unfermented green rooibos tea is also available.
Rooibos tea has a sweet, delicate, and earthy flavor. It contains several antioxidants, which may help explain some of the tea’s health benefits.

Tannins interfere with the body’s absorption of iron, particularly nonheme iron, which is the form that comes from plant-based foods.

3. Rich in antioxidants
Antioxidants are important for human health because they stop free radicals from damaging cells in the body.

Studies in humans have found that rooibos tea consumption increases the levels of antioxidants in the body, but that the effects are small and wear off quickly.
4. Heart health
Antioxidants are important for a healthy heart, which is why rooibos tea may provide cardiovascular benefits. It may also keep cholesterol levels in check.
At the end of this period, the participants had significantly reduced low-density lipoprotein, or “bad,” cholesterol levels and significantly increased high-density lipoprotein, or “good,” cholesterol levels, in comparison with the control group.

The tea also stopped the formation of new fat cells and encouraged quicker fat metabolism.
7. Fewer wrinkles
If a person applies rooibos tea topically, it may improve the appearance of the skin by reducing wrinkles, according to some research.
The researchers found that the tea and rooibos mixture was most effective at reducing wrinkles, while ginkgo was best for moisturizing the skin.
However, it is unlikely that drinking rooibos tea will provide any notable skin benefits.
Other reported benefits
Some people advocate drinking rooibos tea to help treat:
- digestive problems
- mental health issues
- poor appetite
There is no scientific evidence on the effects of rooibos tea for these complaints, however.
People can enjoy rooibos tea hot or cold, in a similar manner to black tea.
For the best results, brew it according to the instructions on the packet. As a general rule, use 8 ounces of boiling water per teabag or a heaping teaspoon of loose leaves.
Allow the tea to steep for at least 5 minutes. Drink the tea plain or add dairy milk, plant-based milk, honey, or sugar to taste.

Rooibos tea is a good alternative to black or green tea, especially for people who want to avoid caffeine or tannins.

However, research into the benefits of rooibos tea is very limited, and many of the existing studies are in animals and human cells.
While it is unclear how effective rooibos tea is for health conditions in humans, most people can enjoy drinking it without any risks. Any health benefits are a bonus.
