Rooibos tea, a caffeine-free drink constituted of the leaves of a shrub indigenous to South Africa, is a part of the nation’s heritage.
The rooibos plant (Aspalathus linearis) grows within the mountainous Cederberg area of South Africa’s Western Cape province. It has been historically harvested and consumed as a natural tea by the Khoisan folks.
Past making tea, the plant has been touted for its potential well being advantages. Rooibos has scientifically confirmed results as an antioxidant. This can be a pure substance that helps to guard your physique’s cells from harm attributable to dangerous molecules.
It’s additionally an anti-inflammatory: a substance that reduces irritation (redness, swelling, and ache) within the physique. It might probably assist defend the center and liver, regulate blood sugar and enhance pores and skin well being.
Industrial cultivation of rooibos started within the early twentieth century. Scientific analysis into its well being advantages began within the Sixties, when its antioxidant properties have been first reported.
Since then, quite a few research have explored its therapeutic potential.
I’m a researcher specializing in the health-promoting properties of South African natural teas, significantly rooibos and honeybush (Cyclopia spp.).
My newest analysis with colleagues suggests rooibos would possibly supply highly effective well being advantages for the intestine. The research aimed to match the anti-inflammatory and barrier protecting results of an unfermented and fermented rooibos aqueous extract on intestinal porcine epithelial cells. We used pigs as a result of their intestines intently resemble human intestine cells.
We confirmed that rooibos extracts made the liner of the intestine stronger by way of its impact on proteins and diminished irritation.
These results are vital as a result of stronger limitations and managed irritation are important for safeguarding tissues just like the intestine from harm and illness.
Digestive (intestine) problems like irritable bowel syndrome (IBS), constipation and dyspepsia (indigestion) have an effect on over 40 per cent of the worldwide inhabitants. Females usually tend to be affected (49%) than males (36.6%). These statistics present the necessity for elevated consciousness, improved analysis and efficient administration of the issue.
Intestine well being has develop into a serious space of curiosity for anybody seeking to enhance their total wellness. A rising physique of proof hyperlinks poor intestine well being to points like continual irritation, fatigue, anxiousness and autoimmune problems. And with rising curiosity in pure options to prescription drugs, persons are turning to eating regimen and drinks for assist.
Inexperienced and pink rooibos and epithelial intestinal cells
In our research, we explored within the laboratory how several types of rooibos tea extracts have an effect on intestine cells. Our analysis group needed to grasp whether or not rooibos may defend the intestine barrier, the microscopic wall of cells that acts as a bodyguard on your intestines.
This barrier retains dangerous substances out whereas permitting vitamins in. When it’s not working correctly, a scenario also known as a “leaky intestine”, it will probably contribute to digestive problems like irritable bowel syndrome (IBS), inflammatory bowel illness (IBD), and different continual well being issues.

Our research centered on two types of rooibos:
Each sorts of tea come from the identical plant, Aspalathus linearis, however the best way they’re processed modifications their chemical composition, particularly their polyphenols. These are pure compounds identified for his or her antioxidant and anti inflammatory properties. The principle polyphenols are known as aspalathin and nothofagin, and aspalathin is exclusive to rooibos.
The three-year research investigated the anti-inflammatory properties of rooibos extracts in intestinal intestine cells of pigs. Cells have been first handled with the extracts for twenty-four hours. Then the extracts have been eliminated and a bacterial toxin was added for an extra 24 hours. The cells’ response was then evaluated by measuring particular markers (indicators) of irritation, and the barrier integrity of the cells was assessed to find out protecting results.
Irritation and intestine safety
Right here’s what we found:
Whereas rooibos is already identified to be wealthy in antioxidants, our research is without doubt one of the first to obviously present how several types of rooibos have an effect on intestine irritation and the intestine barrier in distinct methods. Understanding this may also help folks make smarter dietary selections and doubtlessly give rooibos a task in gut-friendly therapies or useful meals.
Transferring ahead
Our analysis reveals that rooibos tea, each fermented and unfermented, gives distinctive advantages for intestine well being. Fermented rooibos can scale back intestine irritation and unfermented rooibos may also help preserve a wholesome intestine lining.
Rooibos may at some point be utilized in intestine well being dietary supplements, as pure therapies for inflammatory bowel illness, or in on a regular basis meals designed to help digestion.
This was a laboratory-based research, so extra analysis is required to verify the consequences in people. However the proof to date is promising. And contemplating that rooibos is protected, inexpensive, and already extensively consumed, it’s a low-risk addition to a wholesome way of life.
