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:
“When there’s no future
How can there be sin
We’re the flowers in the dustbin
We’re the poison in your human machine
We’re the future
Your future
God Save the Queen”

“The vilest deeds like poison weeds,
Bloom well in prison-air;
It is only what is good in Man
That wastes and withers there:
Pale Anguish keeps the heavy gate,
And the Warder is Despair.”
—Oscar Wilde (1854–1900)
“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.”
