In this newsletter, we find out more about the role of Rooibos in biodiversity conservation. In particular, we learn about how sustainable Rooibos farming practices can restore natural habitats and contribute to efforts to curb biodiversity loss.

We also take a look at a new study that suggests that brewing a cup of Rooibos might have a purifying effect on the water with which you make your cuppa. This further strengthens the appeal of Rooibos as a health conscious beverage. 

Furthermore, we also discover the various health benefits of Honeybush which was the focus of a recent article that was released on a local news website, Food For Mzanzi.

South Africa is experiencing significant biodiversity loss, primarily due to habitat degradation. Between 1990 and 2018, the country lost approximately 0.12% of its natural vegetation annually, with the rate doubling to 0.24% per year between 2014 and 2018. This accelerating habitat loss poses a serious threat to the nation’s rich biodiversity.

In response to these challenges, the Rooibos industry has demonstrated how sustainable farming practices can protect endangered species, restore natural habitats and contribute to global efforts to curb biodiversity loss.

Marthane Swart, secretariat for the Rooibos Council, highlights how local farmers are taking a proactive approach to conservation. “Many Rooibos farmers are implementing measures to restore and protect the unique biodiversity of the Cederberg region. This includes habitat restoration, conservation of indigenous plant species and the protection of endangered wildlife, such as the leopard of the Cape. Our farmers are showing that sustainable agriculture and conservation can go hand in hand.”

Recent research from Northwestern University suggests that tea may offer an additional benefit beyond its widely recognised soothing properties. The study, set to be published in ACS Food Science & Technology, indicates that tea leaves naturally adsorb heavy metals such as lead and cadmium, potentially reducing contaminants in drinking water. 

By binding these harmful elements to their surface, tea leaves may serve as a natural filtration mechanism before being discarded. This discovery highlights a previously overlooked aspect of tea consumption, with potential implications for public health and water safety.

As part of the study, researchers examined how different tea types influence heavy metal adsorption, comparing traditional varieties like black, green, oolong, and white teas with herbal counterparts such as chamomile and Rooibos. 

Notably, Rooibos—a naturally caffeine-free herbal tea—demonstrated promising adsorption properties, reinforcing its reputation as a health-conscious choice. The study also explored the impact of tea preparation methods, assessing the differences between loose-leaf and pre-packaged tea bags to determine their effect on the filtration process.
