The principle that the dose makes the poison is paramount. It means that all chemicals, from whatever source – human manufacture or natural – are potentially toxic at some dose. This fundamental concept underlies toxicology and is crucial to the assessment of risk from chemicals and their safe use. It is known as the dose-response relationship – it is the amount of the substance that causes it to be toxic, not the substance itself.
Paracelsus (1493–1541) said:
All substances are poisons; there is none that is not a poison. The right dose differentiates a poison from a remedy.
