However, this latest study takes a significant step further by using advanced diagnostic methods to assess heart function in real time. The results of the study were promising, particularly in relation to several key cardiovascular parameters. The participants consumed the equivalent of six cups of either fermented or unfermented Rooibos daily for 12 weeks. These results underscore the potential for Rooibos, particularly in its green form, to positively influence heart health.One of the unique aspects of the study was its focus on the consumption of whole Rooibos, rather than isolating individual compounds.
“Baseline and post-intervention echocardiograms were used to measure changes in heart function,” Hartnick explains. “To see these parameters improve with Rooibos consumption is a major breakthrough,” said Prof Marnewick. “It’s the first time we’ve been able to show these effects in humans.” “Our research contributes to the growing body of evidence that Rooibos could be a valuable part of the solution,” says Hartnick. “By promoting the regular consumption of Rooibos, especially in at-risk populations, we could help reduce the incidence of CVD.”
