Phytoestrogenic potential of cyclopia extracts and polyphenols

Abstract

Cyclopia Vent. species, commonly known as honeybush, are endemic to Southern Africa. The plant is traditionally used as an herbal tea but several health benefits have recently been recorded. This minireview presents an overview of polyphenols found in Cyclopia and focusses on the phytoestrogenic potential of selected polyphenols and of extracts prepared from the plant. © Georg Thieme Verlag KG Stuttgart New York.
