Poison
In the context of biology, poisons are substances that cause disturbances to organisms, usually by chemical reaction or other activity on the molecular scale, when a sufficient quantity is absorbed by an organism. The fields of medicine (particularly veterinary) and zoology often distinguish a poison from a toxin, and from a venom. Toxins are poisons produced by some biological function in nature, and venoms are usually defined as toxins that are injected by a bite or sting to cause their effect, while other poisons are generally defined as substances absorbed through epithelial linings such as the skin or gut.

Famous quotes containing the word poison:
“To save the theatre, the theatre must be destroyed, the actors and actresses must all die of the plague. They poison the air, they make art impossible. It is not drama that they play, but pieces for the theatre. We should return to the Greeks, play in the open air: the drama dies of stalls and boxes and evening dress, and people who come to digest their dinner.”
—Eleonora Duse (1858–1924)
“You know the worst: your wills are fickle,
Your values blurred, your hearts impure
And your past life a ruined church—
But let your poison be your cure.”
—Louis MacNeice (1907–1963)
