The inhabitants of Wupperthal have over many generations consumed rooibos from their territory and it remains of popular medicinal and therapeutic value there, whether as a treatment for skin disorders or even providing relief for babies suffering from colic. Modern studies by academic institutions globally, and specifically by the Oxidative Stress Research Center at the Cape Peninsula University of Technology in Cape Town, South Africa, further enhance our knowledge of the benefits implicit to regular rooibos consumption.
Rooibos is well-known to be a healthy beverage with many health benefits, including:
A 3 year study undertaken by the Agricultural Research Council between 2009 and 2011, supported by the SA Rooibos Council, investigated the variation in polyphenol levels and antioxidant activity in fermented rooibos tea and how this is affected by, among other factors, the quality of grades of the rooibos samples tested.
A key finding of the study is that higher grades are associated with higher polyphenol levels, making higher polyphenol levels an indicator of higher quality rooibos.
Analyses performed by the Cape Peninsula University of Technology and the Japan Food Research Laboratories confirm that the samples of Wupperthal Rooibos used in comparative analyses with other rooibos demonstrated significantly higher phenolic content and ORAC levels, therein speaking to the superior quality of Wupperthal Rooibos.
