acetum

Digitalis to be taken every night for six nights, and a saline draught with forty drops of acetum scillit.

And Horace, in a well-known phrase, speaks of Italum acetum, which the scholiast renders by 'Romana mordacitas'.

The word occurs often in a sense in which acetum is the best representative, associated with verjuice and vinegar.

An Acetum digitalis is officinal in the Netherlands and Germany; an extract and infusion are also used to some extent.
