We have selected Rooibos from the CEDERBERG region in western South Africa. The leaves of this thorny shrub with thin stems and yellow flowers are used to prepare a beverage which, unlike tea, is tannin-free and low in caffeine. In addition to its natural antispasmodic and draining virtues, this plant is also rich in minerals, vitamin C and antioxidants. According to various studies on the health effects of Rooibos, it plays an important role in the proper functioning of the human body thanks to the presence of flavonoids, plant substances such as rutin and quercetin (known as anti-free radicals).
