Poison

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:

    They love not poison that do poison need.
    William Shakespeare (1564–1616)

    I wonder what subtle form of manslaughter is next on the program. Am I to be dropped into a vat of molten steel and become part of a new skyscraper, or are you going to ask this female to kiss me again and poison me to death?
    Ernest Lehman (b.1920)

    What’s the greatest enemy of Christianity to-day? Frozen meat. In the past only members of the upper classes were thoroughly sceptical, despairing, negative. Why? Among other reasons, because they were the only people who could afford to eat too much meat. Now there’s cheap Canterbury lamb and Argentine chilled beef. Even the poor can afford to poison themselves into complete scepticism and despair.
    Aldous Huxley (1894–1963)
