Theory of hormesis

Webb11 mars 2013 · According to the original publication of Southam and Ehrlich in 1943, “ The term hormesis (adj. hormetic) is proposed to designate such a stimulatory effect of sub-inhibitory concentrations of any toxic substance of any organism .” [ 10 ]. Figure 1. WebbHormesis is both a term and a phenomenon. Rooted in the Greek language, it can be translated into “excite” or “stimulate”, referring to the stimulatory effect of various agents on living organisms. This stimulation is often equated with a “beneficial” effect, although as we will see later that this is not necessarily so.
