Who said, 'poison is in everything, and no thing is without poison. The dosage makes it either a poison or a remedy'?

Explanation:
The key idea here is the dose–response concept in toxicology: anything can be poisonous at the right dose, and a substance that is harmless in small amounts can become toxic in larger ones, or vice versa. This line is attributed to Paracelsus, a 16th-century physician often called the father of toxicology, who famously said that poison is in everything and that the dosage makes it a poison or a remedy. The other figures were influential in medicine and science, but this precise viewpoint on dose determining toxicity is linked to Paracelsus.
