What is rooibos?
rooibos is a plant native to South Africa, more specifically the Cederberg Mountains. Its scientific name is *Aspalathus linearis*. Unlike traditional teas, such as black tea or green tea, it contains no theine (or caffeine), making it a popular drink for those wishing to reduce their intake of stimulants.
Origin and composition of rooibos
rooibos comes from the leaves of a shrub belonging to the legume family. These leaves are fermented to produce red rooibos, while green rooibos is obtained without fermentation. The plant contains numerous beneficial compounds, including antioxidants such as aspalathin and quercetin, as well as flavonoids. These elements are known for their positive health effects, including reducing oxidative stress and inflammation.
The recognised benefits of rooibos
rooibos is renowned for its many benefits, including:
- Antioxidants: Aspalathin, an antioxidant unique to rooibos, helps protect cells against damage caused by free radicals.
- Immune system support: Thanks to its anti-inflammatory properties, rooibos can help strengthen the body's natural defences.
- Improved sleep: Free from theine, rooibos is ideal for evening consumption, promoting relaxation and sleep.
- Cardiovascular health support: Studies suggest that rooibos may help reduce cholesterol levels and improve blood circulation.
However, although these benefits are often highlighted, it is advisable to remain cautious about the potential risks associated with this infusion.

Does rooibos pose any health risks?
Despite its many benefits, some studies highlight potential risks associated with excessive consumption of rooibos. It is essential to understand these dangers in order to assess whether this infusion is truly safe for everyone.
Studies on potential risks
Some research has explored the health effects of rooibos. For example, a study conducted in 2010 highlighted potential effects on the liver. Indeed, a high intake of rooibos could lead to liver problems in some predisposed individuals. However, these findings still need to be confirmed by other, larger-scale studies.
Furthermore, rooibos contains phytoestrogenic compounds, which could interact with hormone levels in the body. Although these effects are generally minor, they could pose a problem for people with hormonal imbalances.
Potential drug interactions
Like many medicinal plants, rooibos can interact with certain medicines. For example, its anti-inflammatory action could increase the effect of medicines intended to reduce inflammation, which could lead to a risk of overdose. People receiving medical treatment are therefore advised to consult a healthcare professional before consuming rooibos regularly.
Side effects linked to excessive consumption
Although rooibos is generally considered safe, excessive consumption can cause side effects, including:
- Gastrointestinal irritation: By drinking too much rooibos, some people have reported digestive problems, such as stomach aches or bloating.
- Kidney problems: Although rare, overconsumption could have negative effects on the kidneys due to the oxalates present in the infusion.
It is therefore important to consume this drink in moderation to avoid these undesirable effects.
Is rooibos safe for everyone?
rooibos is often recommended for its benefits, but certain population groups need to be particularly vigilant.
Can pregnant and breastfeeding women drink rooibos?
rooibos is a popular alternative for pregnant and breastfeeding women seeking to avoid caffeine. Its soothing properties make it an ideal drink for promoting relaxation. However, as with any plant, it is advisable to seek the advice of a healthcare professional before consuming it during pregnancy, particularly because of its phytoestrogenic compounds.
rooibos and children: from what age is it recommended?
Children can also benefit from this theine-free drink. It is often used to soothe digestive issues in infants. However, it is best to introduce it in moderation for younger children, as their digestive system is still developing.

How can rooibos be consumed safely?
To make the most of rooibos benefits while minimising risks, it is essential to follow certain consumption guidelines.
Recommended daily amounts of rooibos
It is recommended to not exceed 3 to 4 cups of rooibos per day. This amount allows you to enjoy its antioxidant benefits without risking potential side effects. Each cup of infusion contains around 200 to 300 ml of water, which is ideal for maintaining good daily hydration.
The best ways to prepare rooibos
For an optimal infusion, follow these steps:
- Boil the water and let it rest for a few seconds before pouring it over the rooibos leaves.
- Use around 1 to 2 teaspoons of rooibos for 200 to 250 ml of water.
- Leave to infuse for 5 to 7 minutes to fully release the aromas and antioxidants.
- You can enjoy your rooibos plain or enhanced with honey, lemon or spices such as cinnamon to vary the flavours.
rooibos is also well suited to making iced teas, offering a refreshing and healthy drink for summer.
Conclusion
rooibos is an infusion rich in health benefits, but as with everything, moderation is key. Although it does not have the drawbacks of theine and is packed with antioxidants, excessive consumption could present certain risks, particularly for the liver or in the event of drug interactions. By following quantity recommendations and listening to their own body, everyone can enjoy this drink with complete peace of mind.
