A product of tar. A hot-tasting, sooty-smelling liquid; poisonous if swallowed in moderately large quantity; burning the mouth or skin which it touches.

Physicians advise it in one-drop doses for sick stomach, ulcer of the stomach, etc.

In domestic practice it should be on hand as the most effective remedy for toothache in a hollow tooth The end of a bodkin or knitting-needle should be wrapped around with a little piece of cotton, and this be dipped into creosote. Then, carefully, the cotton should be pressed into the hollow of the aching tooth. (It won't hurt, as it at once kills the sensibility of the exposed nerve-end in the tooth.) If any spills over and burns the gums or lips, rinse at once with cold water. Creosote, so used, does no harm to the teeth.
