Elena Carbone Professor of Nutrition Associate Dean for Curriculum & Academic Oversight, Commonwealth Honors College Hormesis is a characteristic of many biological processes, namely a biphasic or triphasic response to exposure to increasing amounts of a substance or condition. Within the hormetic zone, the biological response to low exposures to toxins and other stressors is generally favorable. The term "hormesis" comes from Greek hórmēsis "rapid motion, eagerness", itself from ancient Greek hormáei…

Webthe toxicological literature. As a result of these initial limitations, we established rigorous a priori entry and evaluative criteria to assess the frequency of hormesis in the toxicological literature. Over 20,000 articles were evaluated from the mid-1960s to the late 1990s, with only 1.5%–2.0% of studies being able to satisfy entry
