Definition of the noun Hormesis
What does Hormesis mean as a name of something?
- stimulation by the use of a low concentration of a toxin
Hormesis is the term for generally favorable biological responses to low exposures to toxins and other stressors. A pollutant or toxin showing hormesis thus has the opposite effect in small doses as in large doses. A related concept is Mithridatism, which refers to the willful exposure to toxins in an attempt to develop immunity against them. Hormetics is the term proposed for the study and science of hormesis.
- also known as 毒物兴奋效应
