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:

    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 (1859–1924)

    I care not by what measure you end the war. If you allow one single germ, one single seed of slavery to remain in the soil of America, whatever may be your object, depend upon it, as true as effect follows cause, that germ will spring up, that noxious weed will thrive, and again stifle the growth, wither the leaves, blast the flowers, and poison the fair fruits of freedom. Slavery and freedom cannot exist together.
    Ernestine L. Rose (1810–1892)

    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)
