"All things are poison and nothing (is) without poison; only the dose makes that a thing is no poison."


German (original quote):
Alle Ding' sind Gift und nichts ohn' Gift; allein die Dosis macht, das ein Ding kein Gift ist.

In other words, the amount of a substance a person is exposed to is as important as the nature of the substance. For example, small doses of aspirin can be beneficial to a person, but at very high doses, this common medicine can be deadly. In some individuals, even at very low doses, aspirin may be deadly. Dose-response assesses the dose levels at which adverse effects were observed in test animals, and these dose levels are used to calculate an equal dose in humans.

Phillippus Aureolus Theophrastus Bombastus von Hohenheim

Born 11 November or 17 December 1493 in Einsiedeln, Switzerland died 24 September 1541 in Salzburg, Austria
