Antioxidant Properties of Rooibos (Aspalathus linearis) – In Vitro and in Vivo Evidence

Systems Biology of Free Radicals and Antioxidants

Abstract

The South African fynbos plant, Aspalathus linearis (Brum.f) Dahlg. (Fabaceae, Tribe Crotalarieae), is traditionally used as a herbal tisane referred to as rooibos or redbush. This plant has claimed medicinal properties based mostly on anecdotal evidence. Rooibos is naturally caffeine free and contains a unique blend of polyphenolic compounds. Based on its in vitro antioxidant potential, a few studies also suggest modulation of oxidative stress/damage by rooibos extracts in experimental animals. More recent studies have examined the bioactivity of rooibos in humans. Together, these factors have contributed to the popularity of this herbal tea as a health beverage, both locally and internationally. This chapter focuses on the in vitro antioxidant activity of rooibos and discusses recent animal and human studies.
