In other words, it can be defined as the concentration required to obtain a 50% effect. [3] Half maximal inhibitory concentration: It is a measure of the potency of a substance in inhibiting a specific biological or biochemical function.
To counter the reduced potency at high dilutions he formed the view that vigorous shaking by striking on an elastic surface – a process termed succussion – was necessary. [4] It has been said that Hahnemann came to this conclusion after deciding preparations subjected to agitation in transit, such as in saddle bags or in a carriage, were ...
It is commonly used as a measure of a drug's potency, although the use of EC 50 is preferred over that of 'potency', which has been criticised for its vagueness. [3] EC 50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/L.
In pharmacology, an effective dose (ED) or effective concentration (EC) is the dose or concentration of a drug that produces a biological response. [ 1 ] [ 2 ] The term "effective dose" is used when measurements are taken in vivo , while "effective concentration" is used when the measurements are taken in vitro .

The parameters of the dose response curve reflect measures of potency (such as EC50, IC50, ED50, etc.) and measures of efficacy (such as tissue, cell or population response). A commonly used dose–response curve is the EC 50 curve, the half maximal effective concentration, where the EC 50 point is defined as the inflection point of the curve.
The study was designed to assess the effects of informational vs. asymmetrically paternalistic approaches to encouraging low-calorie meal choices. The informational manipulations were (1) providing recommendations for daily caloric consumption for a person of
