“…nonconventional treatments for hypercholesterolemia, such as novel drugs based on a natural product, tea catechins (mainly gallate ester derivatives) have been tested successfully both in vitro and in vivo as cholesterol-lowering agents (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). Globally, these fi ndings indicate that catechins exert concerted, multiple-level action involving the upregulation of the LDL receptor ( 15,24 ), the reduction of cholesterol absorption ( 16,26,27 ), and the modulation of both synthetic ( 15,28,29 ) and metabolic pathways ( 24 ).…”
