Hormesis has actually been defined to be a biphasic dose-response marriage wherein the response at small doses is opposite to the outcome at higher doses. Samples of reverse effects of drugs (and radiation) at lower and high doses are available abundantly while in the literature (Calabrese and Baldwin 2001, 2003; Conolly and Lutz 2004; Ali and Rattan 2006).

That is demonstrated in simulations Together with the mathematical design demonstrated in Fig. six, in what is posology which the dose and also the drug influence are plotted independently from time For example the influence of tolerance improvement on dose-reaction curve measurements.
