716. Gentian

Gentian is an excellent tonic and stomachic; but when given in large doses, it acts as an aperient.

It is

used internally

in all cases of general debility, and when combined with bark is used in intermittent fevers. It has also been employed in indigestion, and it is sometimes used, combined with sal volatile, in that disease; but, at other times alone, in the form of infusion. After diarrhœa, it proves a useful tonic. Its infusion is sometimes applied

externally

to foul ulcers.
