Flor•Essence, a blend of eight herbs, is a very precise formulation with a synergistic effect that is much more powerful than taking the herbs individually. Its benefits have been proven time and time again – by the patients treated by Rene Caisse and Dr. Charles Brusch with the specific herbal formula that is now called Flor•Essence, as well as through several studies (in vitro and in vivo). Since Flora became the custodian of this historic herbal blend, many thousands more have experienced the effects of this cleansing tea.
