Take of tar, 2 pints;
water, 1 gallon.
Mix, by stirring them with a wooden rod for a quarter of an
hour, and, after the tar has subsided, strain the liquor, and
keep it in well corked phials.
Tar-water should have the colour of white wine, and an empyreumatic
taste. It is, in fact, a solution of empyreumatic oil, effected by
means of acetous acid. It acts as a _stimulant raising the pulse_,
and increasing the discharge by the skin and kidneys. It may be drank
to the extent of a pint or two in the course of a day.
