Arndt–Schulz rule

The Arndt -Schulz rule, also called the Arndt -Schulz Law, is an alleged directive to the body's reaction to stimuli. It reads:

" Weak stimuli times the life activity, moderately strong stimuli promote, inhibit strong, strongest lift them up. "

This rule was named Friedrich Schulz and Rudolf Arndt psychologist after the pharmacologist Hugo Paul. The two professors from the University of Greifswald developed this policy to 1899.

An example of the Arndt -Schulz rule: A cold stimulus when changing showers boosts the immune system, the same water temperature over time leads to " colds "; a very long time to hypothermia and then optionally to death. Generally, however, this policy needs to be considered individually, such as " What is a weak or strong attraction? ".

Furthermore, the exceptions to this rule so numerous that it should not be referred to as a universal law. For example, many debilitating substances have a different effect, as the policy dictates. In the modern books of pharmacology this policy is no longer cited. The Arndt -Schulz rule was thereby displaced by the theory of hormesis.

The Arndt -Schulz rule is often to explain regulation therapies ( eg, one of the homeopathy ) is used. In homeopathy are in deeper powers of the starting substances only in strong " dilution " exists and the Arndt -Schulz rule is tried, among other things as an explanatory model for the mechanism of action, even if it provides no explanation for the quite usual high potencies, the more no molecules the starting substance.
