The moment sure to their receptor, drugs range inside their capacity to develop an result (intrinsic exercise). A drug's affinity and intrinsic action are based on its chemical construction.
Fig. 1 shows a block diagram of the controlled adaptive process. The process generates a hypothetical compound. Its regulation is disturbed by an exogenous material of precisely the same composition (see Peper 2004b). The diagram comprises the digestive tract, the bloodstream, the process, the process regulator and an adaptive regulator.

If the regulation adapts by itself to the new predicament—it slowly but surely learns to reduce the compensatory reaction—the magnitude on the drug influence settles at a degree decreased proportionally by twenty percent. In the event the dose is amplified to its initial magnitude, the drug result at first raises to about two times the conventional stage.

The small dose mentioned higher than does not confer with the infinitesimal dose or superior “potency” homeopathic medicines. On the other hand, the analysis reveals that it's not the dose even so the information regarding the existence on the material that triggers the compensatory reaction.
