Many of our most powerful medicines, including those for diabetes, chemotherapy, and cardiovascular health, are derived from plant extracts. One reason that plants hold so much potential for human health is that they are able to withstand a variety of destructive forces such as environmental radiation, oxidative damage, and chemical toxins due to their unique ability to manufacture complex molecules called flavonoids. For humans, these same conditions can be lethal. Yet when we consume plants as food and beverages, the protective benefits of these same flavonoids are readily transferred to our bodies!
